A Study on Dichocarpum (Ranunculaceae)

The genus Dichocarpum was established by W. T. Wang and Hsiao in 1964, who divided the genus into 2 sections: Sect. Dichocarpum including 10 species distributed on the mainland of E. Asia, and Sect. Hutchinsonia including 9 species native to Japan. M. Tamura and L. A. Lauener made a revision of the genus in 1968, who divided the genus into 4 sections, three for the species of the mainland of E. Asia, including 3 series and 10 species, and the other for the species of Japan, including 2 subsections, 3 series and 9 species. In the present paper, the genus is divided into 2 sections and 6 series, including 15 species and 3 varieties, and a putative phylogeny of the genus is proposed. The genus may be close to the genus Asteropyrum, and these two genera are rather specialized in Thalictroides (Ranunculaceae), because they have three very similar characters: the petal with a long claw, the stephanocolpate pollen and the chromosome morphology. The genus has 2n=24, 35(36?), which indicates that its basic number is X=6, and the species on the mainland of E. Asia (Sect. Dichocarpum) may well be paleotetraploids, whereas those in Japan (sect. Hutchinsonia) are paleohexaploids. Most of the advanced species are distributed in Japan and the most primitive ones in China and the Himalayas, the distribution pattern seggests that the Japanese members of this genus might have immigrated from China in the Tertiary, and differentiated and evolved there. The putative phylogeny of the genus is shown in Fig. 2 (at series level)     

The Geonemertes problem (Nemertea)

A new genus of monostiliferous hoplonemerteans, Pantinonemertes gen. nov., provides evidence for the separate evolution of terrestrial nemerteans. The genus is established for two new species found in Australia, P. enalios sp. nov., an intertidal form, and P. winsori sp. nov., which lives in fallen timber in the supralittoral brackish water regions of mangrove swamps. One only of the known species of land nemerteans, Geonemertes agricola from Bermuda, closely resembles these two species morphologically and is transferred to the new genus as Pantinonemertes agricola .
A re-examination of all the known species of Geonemertes has shown that two major groups can be distinguished on the basis of morphological characters. In one group the rhynchocoel musculature is in two distinct layers, a frontal organ is present, the mid-dorsal blood vessel has a single vascular plug, and the flame cells are binucleate and reinforced with cuticular support bars. It comprises the genus Pantinonemertes gen, nov, and the Pelaensis or Indopacific group of terrestrial nemerteans, for which the generic name Geonemertes is retained. In the second major group the rhynchocoel musculature is composed of interwoven longitudinal and circular fibres, there is no frontal organ, the mid-dorsal blood vessel bears two vascular plugs, and the flame cells are mononucleate and lack support bars. Five genera, three of which are new, are distinguished in this group. Australian species are united in the genus Argonemertes gen. nov., and New Zealand forms comprise the genus Antiponemertes gen. nov., while Acteonemertes bathamae from New Zealand and the Auckland and Ocean Islands remains in a separate genus. Geonemertes nightingaleensis is transferred to a new genus, Katechonemertes gen. nov., and for Geonemertes chalicophora a previously used generic name, Leptonemertes , is adopted.
A key to the terrestrial, brackish-water and marine nemertean species described in the present paper is provided.

Ultrastructure of muscle cells in Acetabulostoma (Crustacea, Ostracoda) – mussel shrimp from the Ross Sea (Antarctica)

Two new antarctic species of the genus Schizotricha Allman have been studied. The material comes from the Scotia Sea (Antarctica) and was collected by the Spanish antarctic expedition `Antártida 8611'. Both species are described and figured and the systematic position is discussed. A general survey of the geographical and bathymetrical distribution of the antarctic and subantarctic species of the genus is given. Finally, a key for the identification of the antarctic and subantarctic species of the genus, together with a comparative table including main features, are presented.

The genus Rhanterium (Asteraceae: Inuleae)

WIKLUND, A., 1986. The genus Rhanterium (Aateraceae: Inuleae) . This revision of the genus Rhanterium Desf. of the /nu/a-group in the Asteraceae: Inuleae, subtribe Inulinae, is based on studies of herbarium material. The genus is distributed over western North Africa, the Arabian peninsula, Iraq and Iran. Three species are recognized: R. adpressum Coss. & Durieu, R. epapposum Oliver and R. suaveolens Desf. A fourth previously accepted species, R. intermedium Coss. & Durieu ex Pomel, is here considered to be composed of hybrids between R. adpressum and R. suaveolens. A laxonomical recognition of these hybrids is not found to be justified. The morphology, phylogeny and phytogeography of the species are discussed and a cladogram of the genus is proposed.     

A revision of the genus Trabaea Simon (Araneae: Lycosidae)

The pennatulacean genus Cavernularia Valenciennes (Octocorallia: Veretillidae)

Two new species of sea pens referable to the genus Cavernularia Valenciennes are described from Natal and Transkei, east coast of southern Africa, at depths of 24 and 190 to over 300 m. The two new species are distinguished from other members of the genus by unique combinations of features regarding the axis, colonial growth form, autozooid size, as well as the size, shape, and distribution of sclerites. A comparative review of the genus is included. The 13 presently recognized worldwide species are differentiated and a key for their separation, together with a table of comparative characters, is provided. Of these, ten (77%) are Indo-Pacific in distribution whilst the remainder (23%) are presumably restricted to the eastern Atlantic. Four species are presently recorded from southern Africa. The deepest known bathymetric stations for the genus are here recorded from northern Namibia at 274 m, and from northern Natal at 310/320 m. Relationships to members of the related genus Cavernulina Kükenthal & Broch are discussed.     

Taxonomic revision of Driessenia (Melastomataceae)

The genus Driessenia Korth. comprises fourteen species and two varieties. Eleven species are endemic to Borneo, the remaining three species occur on Sumatra, Java or Sulawesi. Five species ( D. sessiliflora, D. planopetiolata, D. attenuata, D. grandithyrsa and D. aequiappendiculata ), one variety ( D. microthrix Stapf var. pteroclada ) and one combination ( D. dispar (Cogn.)) are new. The genus Triuranthera Back. is made a synonym of Driessenia . The revision includes a key to the species, illustrations of various floral parts and maps of distribution.     

Die Entwirrung desBotrytella(Sorocarpus)-Komplexes (Ectocarpaceae,Phaeophyta)

Sorocarpus Pringsh. is a later synonym forBotrytella Bory. Four species of the genus are known from northern European coasts. Three of them are found at Helgoland (North Sea), type locality of bothBotrytella uvaeformis (Pringsh.) andB. reinboldii (Reinke). A third species, most frequently seen, still remains unnamed. Plants of similar habit, however, have been described from Japan. The type species for the genus,Botrytella micromora Bory, was originally published asEctocarpus siliculosus β.uvaeformis by Lyngbye. A sample from Danish waters proved to be identical with it. In a previous paper (Kornmann & Sahling, 1984), the life history of two species was studied and the investigation is now extended to include the other two, demonstrating the conformity of the four species with the genus characters as to morphological and developmental features.
