Aspidistra punctatoides Yan Liu & C. R. Lin (Ruscaceae) is described and illustrated as a new species from limestone areas in southwestern Guangxi, China, near the border with northern Vietnam. It resembles A. punctata Lindl. in leaf size, a campanulate perianth densely covered with purple spots, lobes adaxially with two fleshy keels, and the peltate stigma, but differs by the stigma being adaxially truncate and densely papillate, and by the margin being 3‐ or 4‐lobed with lobes emarginate at apex. 相似文献

The genus Aspidistra with almost 100 species is the most diverse in southern China and northern Vietnam. We describe a new species Aspidistra phanluongii N.Vislobokov from southern Vietnam. Species of Aspidistra are herbs characteristic of Southeast Asian forests. Flowering of these plants can be considered cryptic. There are no recorded field observations on phenology, biology of flowering or pollination of Aspidistra. Previously proposed pollinators of Aspidistra include collembolans, amphipods, fungus gnats (Diptera: Mycetophilidae, Sciaridae) and even slugs. We present observation data on the flowering of A. phanluongii in the wild. Flowers were visited by flies of Megaselia (Phoridae) and ants. Megaselia flies, well-known pollinators of numerous tropical plant species, are shown to be likely pollinators of Aspidistra phanluongii. The present study does not provide evidence of pollination by fungus gnats. 相似文献

报道了产自云南屏边的中国蜘蛛抱蛋属一新记录种——垂花蜘蛛抱蛋(Aspidistra nutans Aver.&Tillich)。该种是2017年发表的新种,采集于越南西北部地区,原文缺少果实描述,现补充描述该种果的形态特征。本种与辐花蜘蛛抱蛋(A.subrotata Y.Wan&C.C.Huang)在形态上相近,但其叶片中脉和侧脉明显突出,花梗近先端向下弯曲,长0.8~4.5 cm,花下垂,常贴生于地面,花被紫褐色,常平展,柱头纯白色(后者叶脉凹陷,花梗直立,长约5 mm,花斜向上开,花被暗紫色,内面具有小乳突,柱头白色带紫色斑点)而显著有别于后者。 相似文献

A new species of Exostyles (Leguminosae, Papilionoideae, Swartzieae s.l.), from Paraná State, Brazil
LUCIA HELENA SOARES-SILVA VIDAL DE FREITAS MANSANO 《Botanical journal of the Linnean Society. Linnean Society of London》2004,146(1):103-106
A new species Exostyles godoyensis Soares-Silva & Mansano (Leguminosae, Papilionoideae, Swartzieae), endemic to Paraná state in southern Brazil, is described and illustrated. The new species is distinct from all the other species of Exostyles in having a leaf with up to five leaflets, while the other species have at least seven leaflets per leaf. The new species is distinct from Exostyles amazonica Yakovlev in its longer stamen filaments and ovary stipe and from E. glabra Vogel and E. venusta Schott by its shorter anthers. In addition to these morphological characters E. godoyensis has a disjunct geographical distribution. © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 146 , 103–106. 相似文献

Li & S. C. Tang, but differs in having the perianth white by the sides, white pistils, bracts longer than the perianth, anthers only 2 mm long, pistil obconical and stigma slightly enlarged, 4–5 mm in diameter. The new species is currently only known from the type locality in southwestern Guangxi, near the border to northern Vietnam. 相似文献

Four new Entoloma s.l. species (E. azureosquamulosum, E. caeruleoflavum, E. hainanense, and E. subtenuicystidiatum) are described from southern China. E. azureosquamulosum fits well within the section Rhamphocystotae, E. caeruleoflavum belongs to the section Entoloma, E. hainanense is placed in the section Calliderma, and E. subtenuicystidiatum is a species in the section Cyanula. Preliminary phylogenetic analyses for the four new species are provided based on ITS and LSU sequences in this paper. 相似文献
