中国天门冬科植物一新记录种——暹罗万年青OA
Rohdea siamensis(Asparagaceae),a Newly Recorded Species in China
暹罗万年青(Rohdea siamensis)原产泰国和老挝,近期发现中国云南马关县古林箐省级自然保护区亦有其自然分布种群,凭证标本藏于中山大学标本馆(SYS).该种与分布在中国南部的开口箭(R.fargesii)形态相近,但叶片呈剑形,苞片较长且边缘有小锯齿.此新记录种的发现对万年青属植物系统分类学、生物地理学和区域生物多样性等方面的研究具有重要意义,同时也为探讨西南地区和中南半岛植物区系的关系等提供了研究材料.
Abastract Rohdea siamensis,originally native to Thailand and Laos,has recently been found to have its natural populations in the Gulinqing Nature Reserve in Maguan County,Yunnan,China.The voucher speci-men is deposited in the Sun Yat-sen University Herbarium(SYS).This species is morphologically similar to R.fargesii,which is distributed in Southern China,but it features sword-shaped leaves,elongated bracts with the serrated margin.The discovery of this newly recorded species holds significant implications for studies on the systematic taxonomy and biogeography of the genus Rohdea and the regional biodiversity.It also provides research material for exploring the floristic relationships between Southwest China and the In-dochina Peninsula.
