Typification and synonymy of names in Santolina (Asteraceae: Anthemideae) published by Hoffmannsegg and Link

During recent studies in the Santolina rosmarinifolia L. aggregate, nomenclatural problems with the the names S. impressa and S. semidentata published by Hoffmannsegg and Link were revealed. Here, both names are neotypified and S. rosmarinifolia var. cinerea Pau & Merino and S. zamorana Losa are lectotypified. The criteria used to recognise S. impressa and S. semidentata and their diagnostic characters are discussed. Revision of the lectotypes of S. rosmarinifolia var. cinerea Pau & Merino and of S. zamorana Losa suggests that both names are synonyms of S. semidentata. The full synonymy of S. impressa and S. semidentata is provided.     

Typification and delimitation of Omphalina Quel

The typification of the genus Omphalina Quél, is discussed. There is conclusive evidence to prove that the type should be Omphalina umbellifera (L. ex Fr.) Quél. = O. ericetorum (Fr. ex Fr.) M. Lange and not a species now referred to as O. pseudoandrosacea (Bull, ex St.–Amans) Mos. = O. grisella (Weinm.) Mos. A neotype for O. ericetorum is selected. The recent classifications of Omphalina and related genera are not convincing, and a rearrangement of Gerronema, Phaeotellus, Ric–kenella , and Haasiella inside genus Omphalina is proposed. A series of corresponding new combinations are made or validated.     

Typification of Sphagnum capillifolium (Ehrh.) Hedw.

Abstract

On the basis of the protologue, the name Sphagnum nemoreum Scop. is treated as a nomen dubium and consequently is rejected. S. capillifolium (Ehrh.) Hedw. is lectotypified through a Dillenius specimen, and is proposed to be adopted as the correct name of this species.     

Typification and synonymy of <Emphasis Type="Italic">Meriania</Emphasis> species (Merianieae – Melastomataceae) from Brazil

Taxonomic studies of Brazilian Meriania species (Merianieae – Melastomataceae) have identified taxonomic and nomenclatural gaps. The present work proposes one new synonym, M. sanchezii, for M. paniculata; one new neotypification of M. glabra; and five lectotypifications for M. calophylla, M. glabra var. parviflora (= M. glabra), M. paniculata, M. pergamentacea (= M. robusta), and M. urceolata.     

A taxonomic revision of Calymperes in southern India and neighbouring islands

Abstract

The fourteen species of Calymperes occurring in southern India and neighouring islands are described and their relationships discussed. Syrrhopodon subgenus Heliconema is raised to generic status and a nomenclatural account of its single Asian representative is provided (Heliconema peguense (Besch.) L. T. Ellis and A. Eddy).

Typification of Nordic vascular plants. 1. Names published by G. Wahlenberg

Names of sixtyone taxa described by G. Wahlenberg based on Nordic material are typified. An additional four are listed but no type material is traced. Wahlenberg's four journeys and various modifications of his handwriting are presented. Flora nordica notes no. 4     

Typification of the name Thymus serpyllum L. (Lamiaceae)

Lectotypification of the name Thymus serpyllum L. (Lamiaceae) is presented. The name is typified by a specimen from the Burser herbarium (UPS), the only one which corresponds well with the present concept of T serpyllum and undoubtedly represents original material.     

Typification of the Boissier names in Anthriscus Pers. (Apiaceae)

Boissier described several taxa in Anthriscus , summarized in his Flora orientalis account. The names include A. lamprocarpa, A. kotschyi, A. ruprechtii, A. tenerrima, A. t. var. leiocarpa, A. anatolica, A. macrocarpa, A. nemorosa var. mollis, A. n. var. glabra; the hst four are still recognized as separate species. These names are typified in this paper, based on the material in Boissier herbarium at G.

Oscillatoria agardhii var. suspensa nov. var.

Zusammenfassung Oscillatoria agardhii var. suspensa n. var. ist ein Süßwasser-Planktont, der O. agardhii nahe steht, sich aber durch geringere Abmessungen und den Bau der Trichom-Enden unterscheidet. Sie wurde durch Waschen von anderen Organismen befreit, was bisher noch bei keiner Cyanophycee gelungen war.Die Art lebt im Wasser schwebend. Nur in alten Kulturen sammelt sie sich an der Oberfläche an.O. agardhii var. suspensa ist streng photo-autotroph und macht von organischen Nährstoffen keinen Gebrauch. Sie ist sogar sehr empfindlich gegen manche von ihnen, besonders gegen Glucose (aber nicht gegen andere Zucker), die schon in geringen Konzentrationen die Vermehrung unterdrückt.Die weißlich-grüne Farbe der Art wird durch die Pseudovacuolen bewirkt; der Chlorophyllgehalt ist aber nicht geringer als der von anderen Cyanophyceen, die tief blaugrün aussehen.

---

Summary Oscillatoria agardhii var. suspensa n. var. is a freshwater planktont allied to O. agardhii but differing in smaller dimensions and the shape of the trichome-ends. It was freed from other organisms by the washing procedure, a technique that had not yet been successful in any member of the Cyanophyceae.The organism lives suspended in the water except in old cultures when it tends to accumulate near the surface.O. agardhii var. suspensa is strictly photo-autotrophic not utilizing any organic nutrients and even to some of them very sensitive, particularly to glucose (though not to other sugars) which prevents growth at minute concentrations.The whitish green hue of the species is due to pseudovacuoles while the content of chlorophyll is not lower than that of Cyanophycean species appearing deep blue-green to the eye.

     

Typification of the Linnean species of Saxifraga

WEBB, D. A., 1987. Typification of the Linnean species of Saxifraga. Types (mainly lectotypes) arc assigned to all the species of Saxifraga described by Linnaeus. There are 38 names in all, of which one is now assigned to Bergenia, one is known to be a hybrid, three have been rejected in the past as nomina ambigua, one was later reduced to synonymy by Linnaeus himself, while 32 are accepted as valid species today. Three have been previously typified by Pugsley, one by Steam and one by the author; for the others the types are newly proposed here. Nineteen names are typified from the Linnean herbarium in London (LINN), three from the Linnean herbarium in Stockholm (S), seven from the Burser herbarium at Uppsala (UPS), one from the Tournefort herbarium in Paris (P), and eight from illustrations cited by Linnaeus in synonymy. Lists are appended of all specimens of the genus in the Linnean herbaria in London and Stockholm and the Burser herbarium at Uppsala, and a determination is given for each specimen, though in some cases these can only be tentative. The specimens include 15 species which Linnaeus did not describe, though in the case of five he probably regarded them as varieties.
