The nomenclatural notes, discussed in the present communication, are based on the revision of Iris Linnaeus (1753: 38) names described from Turkey, considering this genus in its wide sense (e.g., Dykes 1924, Mathew 1989, Güner 2012). Iris haussknechtii Bornm. ex Baker (1892: 4) is a species endemic to Turkey referred to I. ser. Spuriae (Diels 1930: 502) Lawrence (1953: 361) of I. sect. Limniris Tausch (1823: without pagination), treated at the generic level under the name Chamaeiris Medikus (1790: 417) (Crespo 2011, Crespo et al. 2015). It is a rhizomatous, perennial herbaceous, compact plant, with two terminal pale yellow or yellow and white flowers on single stem, the perianth segments with only yellow veins, and the narrow, rather tough leaves slightly shorter than flowers. According to some authors (Dykes 1912, 1924, Peckham 1939, Mathew 1984), it is a close relative to I. sintenisii Janka (1877: 244), except for the colour of the flowers, the shape of the outer perianth segments, the fact that the spathe valves are not sharply keeled (Dykes 1924), and the reported chromosome number: 2n = 18 in I. haussknechtii (Özkan et al. 2001, as “I. kerneriana”) vs 2n = 16 in I. sintenisii (Popova & Ceschmedjiev 1975). Based on herbarium specimens examination (deposited at E, K, and P; acronym according to Thiers 2019), we conclude that I. haussknechtii is distributed in the following northern Turkey provinces: Canakkale, Balikesir, Bolu, Kastamonu, Cankiri, Ankara, Corum, Sinop, Amasya, Tokat, Erzincan, as well as in Eskisehir, Afyonkarahisar, Kirikkale, Kirsehir, and Sivas (A. Güner, pers. comm.). This plant usually occurs in open sites, on stony soil amongst woodland, in dry meadows, scrubland, and on steep stony slopes at elevations ranging from 1150 to 2350 m (Mathew 1984). At the best of our knowledge, the name I. haussknechtii has not yet been typified. After the examination of all the original material and protologue, we designated the lectotype for this name.

The distribution of Sonchus palustris in Slovakia was studied using herbarium specimens and literary sources. The herbarium studies, supplemented with targeted field search in the years 2015–2018, revealed 61 new localities and confirmed many other older locations. The species has been recorded in 19 phytogeographical districts and sub-districts of Slovakia. Most of the records are concentrated in the Podunajská nížina lowland in SW Slovakia and in the Ipel'sko-rimavská brázda region in southern Slovakia. Our results showed that the species is relatively common in different types of wetlands and its re-evaluation in the recent version of the Slovak red list is not needed. Chromosome number data for two new populations in eastern Slovakia (both 2n = 18) were counted. The distribution map is given.

A taxonomic revision of Hibiscus trionum from Egypt was undertaken using morphological and cytological studies of field collections and herbarium specimens. The data indicate that all specimens so far collected in Egypt belong to H. tridactylites, rather than H. trionum. This paper includes a comprehensive description of H. tridactylites, its occurrence, a comparison with other species in the H. trionum complex, and comments on habitat, along with images for easy identification. In addition, chromosome counts for this species from Egypt have been determined for the first time, which add to existing information on chromosome counts for the species from different regions of the world.

The taxonomic notes in this article are based on the result of an analysis of the protologues, relevant literature, and a study of herbarium specimens of Iris sect. Hexapogon. This section comprises species with bearded claw in both outer and inner segments of perianth. These are relatively poorly known psammophytes occurring mostly in the desert and semi-desert regions of some of the former Soviet Central Asian republics, as well as in Iran, Afghanistan and Pakistan (Baluchistan). It is now generally accepted that I. sect. Hexapogon comprises two species, I. falcifolia and I. longiscapa. The present study has shown that this section contains only I. longiscapa. The name I. falcifolia is for the first time reduced to a synonym of I. longiscapa. A neotype for the name I. longiscapa and lectotypes for the names I. falcifolia and I. filifolia are designated. Notes are provided on the original material for all the three considered names.

The morphological diversity of North American specimens of Arctagrostis latifolia ssp. arundinacea (Trin.) Tzvelev was evaluated for possible varieties within the subspecies by considering (i) descriptions of three previously recognized taxa included in the subspecies, (ii) measurements of spikelet characters of the types of five taxa, (iii) Macoun's illustrations of spikelet diversity, (iv) a morphological study of 130 herbarium specimens, and (v) a transplant garden study. Characters thought to be uninfluenced by environment were examined. These included (i) the seed protein banding patterns revealed by SDS–PAGE, (ii) the guard cell sizes from plants of known chromosome number, and (iii) a study of anther lengths and pollen diameters. The data do not support the recognition of varieties. Key words: SDS–PAGE, transplant garden, pollen, chromosome number, guard cells, Arctagrostis, Poaceae, taxonomy.

Metaphase I

Edible chia seeds, purchased from the local markets in Guatemala, Mexico, and southern California, were used for species identification, chromosome counts, karyotype construction, and meiotic analyses. Plants raised from those seeds had ovate leaves, dense racemose inflorescences, pale-blue flowers, and were identified from herbarium specimens as Salvia hispanica L. Mitotic analyses of root tips from 50 plants showed 2n = 12—the lowest chromosome number in the genus. Chromosomes were small, ranging from 2 to 3.5 pm. One pair of chromosomes was metacentric (with the long arm: short arm ratio, r = 1.5), four pairs were submetacentric (r = 2.6 to 3.6), and one pair was telocentric (r = 12). Meiosis was regular and six bivalents were observed at metaphase I. Ring and rod bivalents averaged 1.53 ± 1.05 and 4.47 ± 1.05, respectively;

The lectotype of Chara pelosiana Avetta 1898 was designated in 2000 by Langangen, who merged the species with Chara fibrosa Agardh ex Bruzelius. Chara pelosiana belongs to the section Agardhia Wood, but the true identity of the species has yet to be confirmed. The purpose of this work is to show some historical and morphological findings regarding this enigmatic species, on the basis of the analysis of herbarium specimens. The original material, which was studied by Avetta, is missing in Italian herbaria, but portions of it have been found in the Herbarium of Jena. Historical research on botanists related with this species resulted in the discovery of several specimens to be considered “original material”, and new unpublished localities in Northern Italy. Morphological observations have been made on portions of herbarium specimens as a contribution to unveil the taxonomic identity of this taxon. The specimens are diplostichous with ecorticate branchlets, have stipulodes in a single row, one or two per branchlet, and spine cell up to 1 mm long.

Solidago ×niederederi Khek (1905: 22) is a hybrid between North-American S. canadensis Linnaeus (1753: 878) and European native S. virgaurea Linnaeus (1753: 880). Solidago canadensis was introduced to Europe in the 17th century (Kowarik 2003). It has spread invasively throughout Europe since the second half of the 19th century (Weber 1998), reaching, besides sites disturbed by human activity, also (semi)natural biotopes, as forest edges, abandoned meadows and field margins which are often inhabited by native S. virgaurea. Their hybrid was discovered for the first time in nature by a local schoolmaster Franz Niedereder in the area of Vorderstoder village (Austria). Niedereder sent a plant material of the assumed hybrid to Eugen Johan Khek (born in 1861, Neuhaus/Jindřichov Hradec; died in 1927, Vienna), the pharmacist and botanist who lived in Vienna since 1889 (Anonymous 1916). Khek described the hybrid species under the name S. ×niederederi in honour of his discoverer (Khek 1905). The protologue indicates that the relevant communication between Niedereder and Khek was going on between July 1900 (when they met for the first time) and February 1905 (when the hybrid’s description was published). Before its description, Khek studied the hybrid for four years and he saw a herbarium material from Niedereder as well as a living material. In the protologue, no particular herbarium specimens or illustrations had been indicated or associated with S. ×niederederi (Khek 1905).

And Behavior

Twelve species of Gryllinae were studied to determine the number, morphology and behavior of their chromosomes. The male diploid numbers ranged from 19 to 31. Gryllus campestris and a population of "G. bimaculatus" from Singapore showed anomalies in chromosome behavior and structure, including breaks, stickiness, C-mitosis, polyploidy, lagging, unequal segregation and non-disjunction in the former and many aberrations and loss of fertility in the latter. One or two B-chromosomes occurred in some individuals of G. veletis, the chromosome number of this species thus varying from 2n ♀ = 29 to 31. In the Gryllinae, karyotypic differences are shown to be more useful than chromosome number at the species level; differences in chromosome number are useful taxonomically at the generic level, when combined with differences in karyotypes.
