Khaosokia caricoides , D.A. Simpson, Chayam. & J. Parn., a newly discovered genus and species of Cyperaceae is described and illustrated. The genus is characterized by a narrowly paniculate dioecious inflorescence with 2–4 nodes, each of the nodes having a leaf-like inflorescence bract that exceeds the inflorescence. Spikelets in both sexes are linear-cylindric and each flower has seven perianth bristles. The nutlet was immature in the specimens examined. The photosynthetic pathway is C3 . Khaosokia is endemic to limestone cliffs in peninsular Thailand; its conservation status is assessed as Vulnerable (VU B1a + 2a). It has affinities to tribes Cariceae, Dulichieae and some members of Scirpeae, but the exact nature of these relationships has yet to be determined. A revised key to the genera of Cyperaceae in Thailand is presented. © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society , 2005, 149 , 357–364. 相似文献

The genus Piper L. is estimated to contain over 1000 species which are distributed mainly in tropical regions of the world. Several species have great economic and cultural importance and are used as foods, medicines, stimulants, antiseptics and antioxidants. Moreover, their essential oil and leaf extracts possess activities against several bacterium strains and fungi. Leaves of P. hispidinervum C. DC. contain a high level of safrole (83%–93%) which is an important raw material for chemical… 相似文献

Aulonemia fulgor shares with most species of this primarily South American genus a paniculate inflorescence, unbranched spikelets (i.e., not pseudospikelets), and weak or scandent culms that bear a single branch at the node. It is unusual in its amphipodial rhizomes and distinctive leaf anatomy in which, unlike most bamboos, the more complex epidermis is the adaxial. 相似文献
