Edaphic Distribution of Some Species of the Fern Genus Adiantum in Western Amazonia1

The distribution patterns of Adiantum species were inventoried at twelve noninundated rain forest (tierra firme) sites in Amazonian Peru and Ecuador. Six species belonging to the genus were found, and four of these were abundant at some of the sites. At six of the sites none of the species was particularly abundant. Both the occurrence and the abundance of the species varied among sites with regard to soil texture and concentration of exchangeable bases and within sites with regard to topography. Adiantum tomentosum) Klotzsch was restricted to loamy soils with intermediate to low content of extractable bases and was locally most abundant in the well drained parts of slopes and ridge tops. Adiantum terminatum Kunze ex Miq. and A. humile Kunze occurred at sites with intermediate to high content of extractable bases, but their relative abundances differed among and within sites. Adiantum pulverulentum L. was restricted to soils with relatively high base concentration. Ecological differences among the species obviously explained many of the differences in their distribution patterns at the local and regional scales, and may be important for the understanding of such patterns at biogeographical scales as well.     

An annotated check-list of the Pteridophyta of Ceylon

The indigenous species of Pteridophyta known to occur in Ceylon number 314. In addition, 18 naturalized species occur as weeds of cultivation or as introduced aliens. Fifty-seven species are endemic to Ceylon and 28 non-endemic species are absent from India. Lists of these and other phytogeographical groupings are given. The full list of species is followed by comments on the taxonomy or nomenclature of 76 taxa. Four new combinations are made: Asplenium polyodon var. bipinnatum (Sledge) Sledge; Deparia polyrhizon (Baker) Sledge; Polystichum harpophyllum (Zenker ex Kunze) Sledge, and Bolbitis appendiculata var. asplenifolia (Bory) Sledge. Athyrium puncticaule (Blume) T. Moore and A. lanceum (Kunze) T. Moore replace A. anisopterum Christ and A. macrocarpum (Blume) Beddome, respectively.

云南鳞毛蕨属毛柄组的分类研究

本文记载了云南产鳞毛蕨属植物18种,其中新种3种,云南新分布的种3种。对一些长期混淆不清的种还进行了分类学讨论。     

Thelypteris amazonica sp. nov. (Thelypteridaceae) from Amazonian Brazil

A new species of Thelypteris subgenus Goniopteris (Thelypteridaceae) is described and illustrated: Thelypteris amazonica Salino & R. S. Fernandes is apparently most similar to Thelypteris anoptera (Kunze) C. Chr. (Brazil‐Bahia) and T. abrupta (Desv.) Proctor (Antilles, Central America, South America), but differs from both by the clavate vein ends, basal vein pairs from adjacent segments not united below the sinuses, and petioles with simple and stellate hairs. Thelypteris amazonica is known only from Amazonian Brazil.     

On the ecology and Fennoscandian area of Chara strigosa A. Br.

Summary The fairly recently established disjunctional Fennoscandian area of Chra strigosa A. Br., which species was earlier known only from a few alpine lakes in the European Alps, is described and mapped. A survey of some of its ecological traits shows that the species requires neutral or alkaline reaction, a relatively high lime content, and probably a low chloride content of the water. The factors involved in the formation of the recent area of the species are discussed.Received for publication 30.X.1953.

A record of the Plain Tiger,Danaus chrysippus,in Turkey

Summary

In this publication, a subdivision of the genus Annenica O. Boettger, 1877 sensu Auct. is proposed. One result of our study is the recognition of the genus Sprattia O. Boettger, 1883 for most of the South Anatolian species of the former genus Armenica. The genus Astrogena Szekeres, 1970, which was synonymised by H. NORDSIECK (1975: 98) with Armenica is redefined and used as a subgenus of Armenica for some species. Extensive recent collections contain new species and subspecies of this genus, which are described here.     

Kompatibilitätsverhältnisse in Chaetomium

Zusammenfassung Weitere Ergebnisse über das Vorkommen von Homo- und Heterothallie in 50 Stämmen aus 18 Arten von Chaetomium Kunze ex Fr. werden mitgeteilt. Unter 13 in dieser Richtung noch nicht untersuchten Arten wurde bei 11 Homo- und bei 2 (C. nozdrenkoae Serg. und C. subaffine Serg.) Heterothallie gefunden.Unter den 18 untersuchten Stämmen von C. elatum Kunze ex Fr. gab es Homosowie auch Heterothallie, während für die 6 untersuchten Stämme von C. cochliodes Palliser, entgegen der Auffassung anderer Autoren, Homothallie nachgewiesen wurde. Bei allen umtersuchten heterothallischen Arten und Stämmen konnten je zwei Kreuzungstypen nachgewiesen werden.

Compatibility in Chaetomium I. Occurrence of homo- and heterothallism in species and strains

Summary Further data are given about the occurrence of homo- and heterothallism in Chaetomium Kunze ex.Fr. 50 strains including 18 species were examined, monospore cultures being isolated by micromanipulation. Among 13 species, not previously investigated in this respect, heterothallism was noted in only 2 cases (C. nozdrenkoae Serg. and C. subaffine Serg.).In 18 strains of C. elatum Kunze ex Fr. homothallism as well as heterothallism was observed, while all 6 strains of C. cochliodes Palliser, in contradiction to other investigators, were identified as homothallic. Two opposite mating types were indicated in all heterothalic species and strains.

Typification of Smittium, an important genus in the taxonomy of Harpellales

The Harpellales genus Smittium is based on a type species, S. arvernense, which was described by Poisson in 1937 without designation of a type specimen. Smittium arvernense has not been reported since its original publication. Because the other 79 species of Smittium cannot be compared to the type species, a lectotype is proposed as well as an epitype for that lectotype that is also the holotype of S. mucronatum. Because Smittium is believed to be polyphyletic these type designations will provide stable application of names and, as well resolved phylogenetic analyses of member species emerge based on morphological and DNA sequence characters, they will provide a foundation for a more robust and revised classification.     

A revision of the Afrotropical taxa of the genus Amerila Walker (Lepidoptera: Arctiidae)

This paper comprises a complete revision of the Afrotropical species of the genus Amerila ( Rhodogastria auct.), based on adult morphology. Examination of type material for most described taxa has resulted in numerous taxonomic changes. From a total of forty-seven previously described African taxa, thirty-five species including five newly described species and two new subspecies are recognized. For ten taxa, lectotypes have been selected, and for one species a neotype had to be designated. For each species, in addition to synonymy, a brief diagnosis based on external characters and genitalia is given, and the known distribution summarized. All species are illustrated by photographs and illustrations of male genitalia (except A.rufifemur , the male of which is unknown), and a key for determination of males by external characters is provided.     

Annotated catalogue of the types of Indo-Burmese non-marine Gastropoda deposited in the Faculty of Tropical Medicine,Mahidol University,Thailand

ABSTRACT

Four decades after its publication, Rolf A.M. Brandt’s 1974 monograph on the non-marine molluscs of Thailand remains the main authority on freshwater and estuarine species for Southeast Asia and includes up to 165 new species of snails and bivalves described by Brandt and colleagues in the same book and preceding publications. All the holotypes are lodged at the Forschungsinstitut und Naturmuseum Senckenberg in Germany, and are largely inaccessible to Thai and other Southeast Asian researchers, who rely heavily on the Brandt collection as a key reference. Paratypes were, however, donated to various other collections, including some in Thailand. We present the first catalogue of 45 paratypes of gastropods of the Brandt collection, described from Thailand, Laos and Cambodia, which are lodged at the Faculty of Tropical Medicine, Mahidol University, Thailand.
