Systematic Importance of Perigynium Morphology and Achene Epidermal Silica Body in Sixteen Species of Carex L. (cyperaceae) from the Darjeeling and Sikkim Himalayas, India
The cosmopolitan genus Carex L. represented about 1,800-2,000 species mainly in temperate and cold regions of the world. 49 species of Carex found in North-eastern India and 33 species in the rest part of India. Systematics of different taxa (subgenera, sections species pairs etc.) of the genus is quite complicated. In Carex, utricle morphology and fruit epidermal silicabodies have been used to...
متن کاملStructures of new sesquiterpenes from Curcuma comosa.
From the methanolic extract of the rhizomes of Curcuma comosa cultivated in Thailand, six new sesquiterpenes, (+)- and (-)-comosols (1, 2), comosones I (3), II (4), and III (5), and dimethoxycurcumenone (6), were isolated. Their structures were elucidated on the basis of chemical and physicochemical evidence.

Subgenus Primocarex was generally thought to be artificial and derived from diverse multispicate species. Relationships of rachilla-bearing species of subgenus Primocarex, however,...
متن کاملFourteen polymorphic microsatellite markers for a widespread limestone endemic, Carex eburnea (Cyperaceae: Carex sect. Albae)1
PREMISE OF THE STUDY Microsatellite primers were developed for a widespread limestone endemic sedge, Carex eburnea, to facilitate investigation of the genetic diversity and phylogeography of this taxon and its closest relative, C. mckittrickensis. METHODS AND RESULTS Forty-eight primer pairs were designed from Illumina sequence data and screened for suitability. Fourteen of these primer pairs...
