This paper presents the flower morphology, pollination mechanisms and seed germination of three indigenous medicinal plants of Bangladesh namely, Asclepias curassavica L., Clerodendrum viscosum Vent. and Scoparia dulcis L. The minimum days taken for seed germination in Asclepias curassavica, Clerodendrum viscosum and Scoparia dulcis are 6, 14 and 9, respectively. Epigeal type of seed germination has been noted in Asclepias curassavica and Scoparia dulcis, whereas hypogeal type of seed germination has been found in Clerodendrum viscosum. Fruit production is highest in Scoparia dulcis among the species studied and a maximum of 304 seeds are produced per fruit in it. Maximum 108 seeds are produced per fruit in Asclepias curassavica. Among the species investigated Asclepias curassavica and Clerodendrum viscosum are cross-pollinated, and Scoparia dulcis is self-pollinated. Butterflies, bees and ants are noted to be the pollinators in Asclepias curassavica and in Clerodendrum viscosum black ants, butterflies and long tongue hawk moths are the pollinators.Keywords: Taxonomy; pollination; seed germination; Asclepias curassavica L.; Clerodendrum viscosum Vent.; Scoparia dulcis L.DOI: 10.3329/bjpt.v17i1.5391Bangladesh J.

Germination Behaviour

This paper focuses on seed germination of six indigenous medicinal plants of Bangladesh, namely Adenanthera pavonina L., Helicteres isora L., Murraya paniculata (L.) Jack, Psoralea corylifolia L., Uraria lagopodioides (L.) Desv. and U. picta (Jacq.) Desv. ex DC. The minimum days taken to germinate seeds in Adenanthera pavonina L., Murraya paniculata (L.) Jack, Psoralea corylifolia L., Uraria lagopodioides (L.) Desv. and U. picta (Jacq.) Desv. ex DC. are 12, 36,  10, 39 and 14, respectively. Seeds were not germinated in Helicteres isora L. indicating that seeds are not suitable for propagation, however, propagation through stem cutting in this species revealed that plants flowers and set fruits in the same year and take only six to seven months. Epigeal type of seed germination was observed in all cases.DOI: http://dx.doi.org/10.3329/bjpt.v21i1.19270Bangladesh J. Plant Taxon. 21(1): 71-76, 2014 (June)

The genus Zephyranthes Herb. is revised along with its pollination mechanism, seed germination and vegetative propagation. Detailed taxonomy of four Zephyranthes species occurring in Bangladesh, namely, Z. atamasco (L.) Herb., Z. candida (Lindl.) Herb., Z. carinata Herb. and Z. tubispatha (L’Her.) Herb. ex Traub. was studied with their updated nomenclature, important synonyms, phenology, specimens examined, habitat, distribution, economic value and mode of propagation. A dichotomous bracketed key is provided for easy identification of the species. Pollination investigation reveals that all studied species of Zephyranthes are self-pollinated. Minimum five days were required for germination of seeds in Z. atamasco, and three days each in Z. candida, Z. carinata and Z. tubispatha. Pseudovivipary type of germination has been reported in Z. candida and Z. carinata for the first time. The maximum number of seeds (30) per fruit are produced in Z. tubispatha, whereas the minimum seeds (2) per fruit are found in Z. atamasco. Vegetative propagation through bulb was found more suitable than seeds in Z. atamasco, Z. candida and Z. carinata. Pollen viability has been found 100% in Z. candida, and Z. tubispatha, whereas, Z. atamasco and Z. carinata have shown 80% and 98% viability, respectively. Bangladesh J.

Traditional knowledge is an important source of obtaining new phytotherapeutic agents. Ethnobotanical survey of medicinal plants was conducted in Nossa Senhora Aparecida do Chumbo District (NSACD), located in Poconé, Mato Grosso, Brazil using semi-structured questionnaires and interviews. 376 species of medicinal plants belonging to 285 genera and 102 families were cited. Fabaceae (10.2%), Asteraceae (7.82%) and Lamaceae (4.89%) families are of greater importance. Species with the greater relative importance wereHimatanthus obovatus(1.87),Hibiscus sabdariffa(1.87),Solidago microglossa(1.80),Strychnos pseudoquina(1.73) andDorstenia brasiliensis,Scoparia dulcisL., andLuehea divaricata(1.50). The informant consensus factor (ICF) ranged from 0.13 to 0.78 encompassing 18 disease categories,of which 15 had ICF greater than 0.50, with a predominance of disease categories related to injuries, poisoning and certain other consequences of external causes (ICF  =  0.78) having 65 species cited while 20 species were cited for mental and behavioral disorders (ICF  =  0.77). The results show that knowledge about medicinal plants is evenly distributed among the population of NSACD. This population possesses medicinal plants for most disease categories, with the highest concordance for prenatal, mental/behavioral and respiratory problems.

: Medicinal plants are traditionally familiar to treat various physical abnormalities, diseases and illness throughout the world. A very large number of plant wealth has been offered by the nature for all living organisms, which preserves medicinal excellence. Traditionally in the rural areas folk medicinal practitioners perform a more ordinary manner of medicine, where medicinal plants constitute the foremost and most often only components of formulations. Geographical and cultural factors of Bangladesh create it an abundant source for herbal remedies. Nowadays, several medicinal herbs having their hypnotic and sedative effects are thoroughly used in the treatment of various psychiatric related disorders that include anxiety and insomnia. Sedatives are that types of drugs which diminish the action, inducing a calming and relaxing outcome. Sedatives, in general, produce sleep at higher doses. From recent years the prevalence of psychiatric disorders which include anxiety and insomnia is rising and therefore different researches are going on to reveal better medicine to treat these disorders. In this present review, we have performed a comprehensive literature search to find out the five most frequently used medicinal plants with sedative effects for the treatment various disorders like anxiety and insomnia and their pharmacological activities in scientific researches. The featured plants of this review articles are, Kaempferia galanga, Cleome Rutidosperma, Kalanchoe pinnata, Calotropis gigantea, Scoparia dulcis L. In herbal and traditional medicines, numerous plants are used in the absence of their scientific validation and we intend to carry out a literature review in order to find out the effective scientific value of the featured plants. This study will help to affirm the uses of these plants as traditional medicine and for researchers to detect the efficient therapeutic drugs according to their pharmacological studies.
