Revision of endemic Marquesas Islands Bidens (Asteraceae, Coreopsideae)
During the preparation of the Vascular Flora of the Marquesas Islands four new species of Bidens (Coreopsideae, Asteraceae) have come to light and are described herein: Bidens woodii W.L. Wagner, J.R. Clark & Lorence, sp. nov. from Ua Pou, and Bidens microcephala W.L. Wagner, J.R. Clark & Lorence sp. nov., Bidens evapelliana W.L. Wagner, J.R.

متن کاملBidens meyeri (Asteraceae, Coreopsideae): a new critically endangered species from Rapa, Austral Islands
Bidensmeyeri (Asteraceae/Compositae) is described and illustrated from Rapa, Austral Islands, (French Polynesia). This new species is presumed to be most closely related to Bidenssaint-johniana from nearby Marotiri Island. Bidensmeyeri may be distinguished from Bidenssaint-johniana based on the length of the peduncle (3 cm versus 10 cm), apex of the inner involucral bracts (glabrous vs. puberul...
متن کاملLectotypification of Linnaean names in Pedicularis (Orobanchaceae)
Ten Linnaean names of Pedicularis (Orobanchaceae) are lectotypified: P. comosa, P. flammea, P. hirsuta, P. incarnata, P. lapponica, P. resupinata, P. rostrata, P. tristis, P. tuberosa and P. verticillata. Lectotypes are designated from the Linnaean herbarium at LINN. The type choices made here maintain the present usage of the corresponding Linnaean names for ten Pedicularis species.
متن کاملLectotypification, emended description and distribution of Planothidium distinctum (Achnanthidiaceae, Bacillariophyceae)
The rare boreo-alpine, oligotraphenic diatom Planothidium distinctum (= Achnanthes distincta) was first described from the western Alps in 1954. Achnanthes hirta, a species described in 1970 from the Pyrenees, is regarded as a heterotypic synonym of Planothidium distinctum but almost all morphological details of P. distinctum are known from the type material of Achnanthes hirta. On the basis of...
متن کاملNovelties in Cardueae (Asteraceae)
The current investigations suggest the segregation of Jurinea cartilaginea from Jurinea, and its placement among Centaureinae. Molecular studies, based on the nuclear ribosomal internal transcribed spacers (nrITS), chromosome number data and pollen morphology, support the morphological results. Based on these results, J. cartilaginea is related to and, therefore, transferred to the genus Karvan...
