摘要:

报道中国柿科(Ebenaceae)柿属(Diospyros)植物二新记录种——粗毛叶柿(Diospyros dasyphylla Kurz)和苏门答腊柿(D. sumatrana Miq.),提供了二新记录种的形态特征、物候期、生境特点和分布等信息,并基于国内的野外调查情况对其进行了濒危等级评估。粗毛叶柿与木果柿(D. xylocarpa Y. M. Shui, W. H. Chen & Sima)相似,区别在于前者的幼枝及叶背密被黄褐色糙毛,成熟果直径约6 cm,宿存果萼长8 mm; 苏门答腊柿与椭圆叶柿(D. elliptifolia Merr.)相似,区别在于其前者的花冠白色,瓶状,果直径约2 cm,宿存果萼直立。凭证标本存放于广西植物研究所标本馆(IBK)和北京林业大学博物馆(BJFC)。这些资料为中国柿属植物多样性研究提供了基础数据。

Abstract:

Diospyros dasyphylla Kurz and D. sumatrana Miq.( Characteristics Ebenaceae )in genus Diospyros of family Ebenacceae are reported as newly recorded species in China. Information such as morphological characteristic, phenological period, habitat characteristics and distribution of the two newly recorded species are provided. The endangered category of the two newly recorded species is assessed based on field survey. D. dasyphylla closely resembles D. xylocarpa Y. M. Shui, W. H. Chen & Sima, and the former can be distinguished by its young branchlets and leaves, which are densely covered with yellow-brown hairs, and mature fruits approximately 6 cm in diameter, accompanied by a fruit calyx measuring 8 mm; while D. sumatrana is similar to D. elliptifolia Merr., but differs in its white and urceolate corolla, fruit 2 cm in diameter and erected calyx. The voucher specimens are deposited in Herbarium of Guangxi Institute of Botany( IBK )and Museum of Beijing Forestry University(BJFC). These findings provide basic data for the biodiversity research of Diospyros plants in China.
