Three new species of Eleocharis R. Br. subg. Scirpidium (Nees) Kukkonen (Cyperaceae) from southern Brazil are described and illustrated: E. angustirostris Trevis. & Boldrini, neesii riograndensis Boldrini. They have fertile proximal scales achenes with longitudinal rows horizontally oriented rectangular cells, characteristic Scirpidium. is distinguished all the Brazilian subgenus by achene narrowing into a neck narrow stylopodium that appears to be continuation neck; related radicans (Poir.)...
Abstract— During the first author’s doctoral research, in part developed at New York Botanical Garden and guided by William Wayt Thomas, several new species of Rhynchospora were discovered when revising NY herbarium specimens. In this study, we describe name one these as waytii , honor renowned sedge specialist friend. is closely related to R. nanuzae but displays distinguishing characteristics such broader leaves, inconspicuous rhizomes, larger spikelets stylopodia. It also exhibits a...
Rhynchospora caduciglumis, a new species of sect. Glaucae C.B. Clarke is described and illustrated. The similar to R. polyantha Steud., but it has shorter spikelets (2.8–4.0 vs. 4.0–5.0 mm), fascicles with fewer spikelets, deciduous scales when the achenes are mature narrower leaves (1.6–2.0 (–3) 2.0–4.0 (–4.5) mm). gollmeri Boeckeler neotypified its disjunct distribution between Venezuela southeastern Brazil discussed.
During the preparation of a taxonomic revision Rhynchospora sect. Longirostres, we found several scientific names that needed to be lectotypified or neotypified. In addition, amazonica subsp. guianensis is being recognized at level species and requires new name, rionegrensis. This described illustrated differs from R. by its lateral terminal, generally turbinate inflorescences, brown spikelet scales, loose fascicles, longer stylopodium. Lectotypes are chosen for Calyptrostylis longirostris...
