Pollen Powder or Sari : Aspects of Morphology, Systematics and Application on Menthol Family Plant          Pollen is the important component of plant to develop through reproductive. Pollen is the male organ of plants that plays an important role in the process of the evolution of plants. Menthol family plants (the Family Lamiaceae) is one of biggest families after Asteraceae. The process of the cross breeding often dominates the process of the evolution to the ment al Family. The research on the menthol Family's pollen aimed to know the affinity and the process of his pollination. The form of pollen of the Family Lamiaceae, was round and hexacolpate, the form was the same as the species member with their relatives. In the process of pollination often helped by the bee where pollen that clung to the abdomen part and the chest of the bee and moved to the other flower where the cross-pollination happen. The process of the cross-pollination happened also because of the same of maturity time between pollen of male and the stigma surface of female. The seed was still being the dominant factor in the reproductive in the Family Lamiaceae. Key words : Pollen, Pollination, Lamiaceae, the Mint family, the bee, the seed Abstrak          Serbuk sari atau dikenal dengan pollen merupakan komponen penting tanaman untuk berkembang melalui reproduktif. Serbuk sari merupakan organ jantan pada tumbuhan yang berperan penting dalam proses evolusi tumbuhan. Tumbuhan Keluarga Mentol (Famili Lamiaceae) merupakan salah satu Famili yang terbesar setelah Asteraceae. Proses perkawinan silang banyak mendominasi proses evolusi pada Keluarga Mentol. Penelitian terhadap serbuk sari Keluarga Mentol bertujuan untuk mengetahui kekerabatan dan proses penyerbukannya. Bentuk morfologi serbuk sari pada Famili Lamiaceae, yaitu bulat dan heksakolpat (hexacolpate), bentuk yang sama dengan jenis – jenis anggota Famili Lamiaceae. Pada proses penyerbukan banyak dibantu oleh lebah dimana pollen yang menempel pada bagian perut dan dada lebah penyerbuk dan berpindah pada bunga yang lain sehingga terjadi penyerbukan silang. Proses penyerbukan silang terjadi juga karena adanya waktu pemasakan yang sama antara serbuk sari sebagai organ jantan dan kepala putik sebagai organ betina. Biji masih merupakan faktor yang dominan pada perbanyakan Famili Lamiaceae.Kata kunci : Serbuk sari, Pollen, Lamiaceae, Keluarga Mentol, Lebah, biji.

The developmental morphology of Cissus antarctica Vent, was followed from seed to seed. As in the other taxa in the family we have examined (Vitis, Parthenocissus, Ampelopsis), both leaves and uncommitted primordia arise on the flank of the apical meristem. Also as in the other taxa, the uncommitted primordium may develop into either a tendril, an inflorescence, or an intermediate organ. An abaxial bract forms on the uncommitted primordium. If the primordium is going to develop into an inflorescence, the lateral arm develops in the axil of the bract. A second order inflorescence arm may also form and it is on these two axillary structures that most of the flowers develop. Each arm of the inflorescence forms a compound series of dichasia, with each dichasium oriented at 90° from the previous one. Flowers are tetramerous. The first two sepals are initiated at approximately 90° to the last-formed inflorescence branch primordium, in the same position as the dichasial bracts would form. Thus the early distinction between a floral and an inflorescence branch primordium is very difficult. A ring primordium then forms and the calyx becomes continuous. The petals arise simultaneously, followed by the stamens, which are petal-opposed. Thus there is no common petal–stamen primordium. The gynoecium arises as a ring primordium, and subsequently two septa form opposite one another on its inner wall. The septa touch, but they do not fuse. Two ovules form at the base of each septum. A floral nectary develops from the ovary base. At anthesis, the greenish petals reflex, usually for a day or less and then are shed, along with the stamens. Fruits are dark bluish and are usually one-seeded. Key words: development, flowers, Vitaceae, Cissus, morphology.

The asymmetrical leaf of Begonia raises both biological and mathematical questions. The leaf organogenesis of two species of Begonia is analyzed in this study, one with asymmetrical, palmately nerved leaves, Begonia scabrida A.DC, the other with quasi-symmetrical, pinnately nerved leaves, Begonia radicans Vellozo. Additional observations on Begonia fagifolia Fischer, a species of the second type, are included for comparison. In the three species studied, the leaf primordia are asymmetrical at initiation, notwithstanding mature leaf symmetry or nervation. In B. radicans, the leaf is asymmetrical at initiation and becomes quasi-symmetrical, while in B. scabrida, it remains asymmetrical throughout. The Begonia leaf thus represents a true case of asymmetry, related to the morphogenetic properties of the vegetative apex. None of the present theories of leaf organogenesis are able to fully account for this phenomenon. Leaf asymmetry represents an ontogenetic constraint in the evolutionary history of Begoniaceae. The hypothesis is presented that the palmately nerved leaf is a plesiomorphic state and the pinnately nerved leaf an apomorphic one that appeared repeatedly within the family.

We describe a new finding of Cirsotrema matugisiense (Ozaki, 1958) from the northern Sea of Japan. This species differs from the other species of the family Epitoniidae having few low, flattened, wide spiral ribs throughout the whole surface of each whorl excluding the base. Most similar to C. matugisiense is Amaea iwaotakii Azuma, 1961 which differs from the former in having the whorls with many distinct minute spiral striae except on the upper third of each whorl (vs. a few low, flattened, wide spiral ribs throughout the whole surface of each whorl excluding the base in C. matugisiense); all axial ribs are rather similar in size (vs. the axial ribs of different thickness, especially on the last whorl in C. matugisiense). Key words: Gastropoda, Epitoniidae, Cirsotrema, Sakhalin, Sea of Japan. Описана новая находка гастроподы Cirsotrema matugisiense (Ozaki, 1958) из Японского моря. Этот вид хорошо отличается от других видов семейства Epitoniidae наличием 6 низких, уплощенных, широких спиральных ребер на всей поверхности каждого оборота, исключая основание. Наиболее сходным c C. matugisiense видом является Amaea iwaotakii Azuma, 1961, который отличается от него наличием оборотов раковины с многими отчетливыми, мелкими спиральными бороздками за исключением верхней 1/3 каждого оборота (несколько низких, уплощенных, широких спиральных ребер на всей поверхности каждого оборота, исключая основание у C. matugisiense); все осевые ребра довольно сходны по размеру (осевые ребра различной толщины особенно на последнем обороте у C. matugisiense).

Strawberry Cultivars

Comparisons were made to determine the cross-pollination potential of four strawberry cultivars. The weight per fertilized ovule of self-pollinated strawberries was compared to that from cross-pollination. Results indicated in 1986–1987 that the weight of strawberries was influenced by cross pollination. In 1986, the primary strawberries obtained by the crossing of Bounty × Glooscap had an average achene weight superior to that of the control. We also noticed the same observation for the secondary strawberries by the crossing of Honeoye × Bounty in 1986 and Redcoat × Honeoye in 1987.Key words: Strawberry, cross pollination, production, xenia

Collections of colonies of the termite Incisitermes schwarzi from mangroves around the coast of Jamaica revealed six chromosomal types, all involving variations or rearrangements of the sex chromosomes. One of the types had a heteromorphic sex bivalent in which the Y chromosome was larger than the X. The other five races had complex interchange multiples: a chain of 11, a chain of 12, a ring of 12, a ring of 14, and a ring of 18 chromosomes. The situation is similar to that described previously for Kalotermes approximatus, another member of the family Kalotermitidae, in the southeastern United States. The different chromosomal types can be arranged in an evolutionary series, each step requiring an interchange or fusion between an autosome and a previously existing sex chromosome. Such polymorphic chromosome systems, containing Y-segregating elements of different evolutionary ages, may offer an unusual opportunity for studying the sequence of changes accompanying the evolution of Y chromosomes.

Previously we reported that tannic acid is a very effective fixative for proteins including polypeptides. Especially, in the cross section of microtubules, thirteen submits in A-tubule and eleven in B-tubule could be observed very clearly. An elastic fiber could be demonstrated very clearly, as an electron opaque, homogeneous fiber. However, tannic acid did not penetrate into the deep portion of the tissue-block. So we tried Catechin. This shows almost the same chemical natures as that of proteins, as tannic acid. Moreover, we thought that catechin should have two active-reaction sites, one is phenol,and the other is catechole. Catechole site should react with osmium, to make Os- black. Phenol-site should react with peroxidase existing perhydroxide.

Middle Class People

Marriage is an important thing in the life of a woman. The importance that our society attaches to marriage is reflected in our literature and it is the central concern of Shashi Deshpade’s novels. In our society where girl learns early that she is ‘Paraya Dhan’, and she is her parents’ responsibility till the day she is handed over to her rightful owners. What a girl makes of her life, how she shapes herself as an individual, what profession she takes up is not as important as whom she marries. Marriage is the ultimate goal of a woman’s life. This paper attempts to probe into the problems of marriage through the protagonists of her novels where one enjoys the freedom of marriage and the other accepts the traditional marriage. Shashi Deshpade highlights the problems of marriage faced by middle-class people in finding suitable grooms for their daughters. This problem is well-illustrated through the characters of her novels. Since the girl’s mind over her childhood is tuned that she is another’s property, she tries to attach a lot of importance to it. it is indeed a tragedy that even in the modern age, Indian females echo the same sentiment where it was marriage which mattered most of them but not to the men. It is a beginning of females sacrifices in life that marriage brings to her. Shashi Deshpande encourages her female protagonists to rise in rebellion against the males in the family matters, instead she wants to build a harmonious relationship between man and woman in a mood of compromise and reconciliation.

Abstract In the paper we present the selected properties of composition relation of the convergent and divergent permutations connected with commutation. We note that a permutation on ℕ is called the convergent permutation if for each convergent series ∑an of real terms, the p-rearranged series ∑ap(n) is also convergent. All the other permutations on ℕ are called the divergent permutations. We have proven, among others, that, for many permutations p on ℕ, the family of divergent permutations q on ℕ commuting with p possesses cardinality of the continuum. For example, the permutations p on ℕ having finite order possess this property. On the other hand, an example of a convergent permutation which commutes only with some convergent permutations is also presented.

Background: Pigmented tumour of the skin is one of the common tumour in human including the benign pigmented tumours (more common) called Nevi tumours and the malignant one called melanoma which was less frequent but the most poor in prognosis. In addition, the others not belonging to these group had the same clinical appearance, so the application of histopathology and immunohistochemistry for the definitive diagnosis was indespensible. Objectives: 1. To describe the macroscopic features of the pigmented tumoral-like lesions; 2. To classify the histopathologic types of the pigmented cell tumours and the other pigmented tumours of the skin. Materials and Method: Cross-sectional research on 55 patients diagnosed as pigmented tumoral lesions by clinician, then all definitively diagnosed by histopathology combining the immunohistochemistry in difficult cases. Results: There was no difference in gender, the disease was discovered most common in adult, especially with the age over 51 years old (58.1%). the most region located was in the face accounting for 60%, following the trunk and limbs (14.6%, 12.8% respectively). All 3 malignant melanomas happened in foot. The most common color of the lesions was black (65.4%), the other ones were rose, grey and blue. Histopathology and immunohisthochemistry showed that the true pigmented cell tumours were 52.6% encompassing benign ones (Nevi tumour) (41.8%), melanoma (5.4%) and lentigo (5.4%). 47.4% was not the true pigmented cell tumour including pigmented basocellular carcinoma (36.4%) and the others less common as histiofibromas, acanthoma and papilloma. Conclusion: the pigmented tumoral-like lesions of the skin could be the true pigmented cell tumours and the others, so the application of the histopathology and the immunohistochemistry after the clinical discovery helps to determine and classify the disease definitely and for the best orientation of treatment as well. Key words: skin tumour, benign pigmented tumour (Nevi), malignant pigmented tumour (melanoma), pigmented basocellular carcinoma
