New taxa within the orderOrchidales

One new tribe (Telipogoneae) and nine new subtribes (Bartholininae, Cheirostylidinae, Elleanthinae, Epidendrinae, Herminiinae, Isochilinae, Oberoniinae, Phragmipeddiinae, Thecopodinae) are described. The status changes for five other taxa are proposed.

The lesser-known protostome taxa: an introduction and a tribute to robert p. Higgins

Most biologists are familiar only with a few of the approximately40 extant animal phyla. The purpose of this symposium was torenew interest in the lesser-known invertebrate taxa, encouragetheir use in research and teaching and to promote the relevanceof high-level systematic studies. This paper reviews the twomajor views of metazoan evolutionary relationships with particularattention to the lesser-known taxa and to some of the new and/orconflicting terminology used in current animal phylogeneticstudy. The current use of lesser-known taxa in research is brieflydescribed, and the discussion that followed the symposium issummarized. The paper concludes with a brief history of thesymposium and a tribute to Robert P. Higgins, who organizedthree "Symposia on the Lesser-Known Invertebrates" over thepast 25 yr.

Taxonomic relationships of the western Asian taxa of Gentiana sect. Pneumonanthe

The taxonomic position of western Asian members of Gentiana sect. Pneumonanthe has long been a matter of conflict. In this paper, the six western Asian species currently recognized as belonging to sect. Pneumonanthe ( G. boissieri , G. calycina , G. freyniana , G. gelida , G. paradoxa , and G. septemfida ) are compared and their relationships established using a morphological phylogenetic analysis. Seed testa and flower and leaf morphological characters were studied and 11 characters were selected for a cladistic analysis. Euro-Siberian and Far Eastern taxa of sect. Pneumonanthe ( G. pneumonanthe and G. scabra ) were used as outgroups. Our results suggest the presence of two morphologically distinct clades within the western Asian gentians: a Septemfida and a Gelida clade. G. calycina and G. freyniana show close affinities to G. boissieri and G. gelida , and are distinct from G. septemfida s.l. Biogeographical aspects of the two groups are discussed.  © 2006 The Linnean Society of London, Botanical Journal of the Linnean Society , 2006, 152 , 197–208.     

New taxa from the Venezuelan Guayana

Seven new taxa, mainly from the Guayana Highland of Venezuela, are described. These include four new species (Cottendorfia atrorosea, Navia emergens, Navia ovoidea, and Pitcairnia nematophora) and one new variety (Cottendorfia brachyphylla var. angustior) of Bromeliaceae, one new species (Swartzia cowanii) of Leguminosae, and one new species (Marlierea pudica) of Myrtaceae.     

New and critical taxa of aquatic hyphomycetes

Species of Alatospora and Margaritispora have been studied in pure culture. The conidial morphology of 33 Alatospora isolates was examined. The concept of Alatospora acuminata is broadened to embrace strains with a high percentage of unbranched and triradiate conidia as well as those with large conidia with an arcuate axis and narrow branch insertion. Alatospora constricta is neotypified, and a new generic name is introduced to accommodate a species with similar conidia but different conidiogenesis. Margaritispora aquatica is neotypified and M. monticola is neotypified and recombined in a new genus.
