Abstract

Abstract: Two new species of Orchidaceae from China, Bulbophyllum malipoense and Arachnis zhaoi, are described and illustrated. The former is related to B. unciniferum, from which it differs by having clustered, ovoid-globose pseudobulbs, smaller leaves 2 - 3.5 cm long, and shorter lateral sepals 1.4 - 1.7 cm long and with their middle margins connate to each other; the latter is akin to A. labrosa , from which it differs by its pale yellow-green flowers lacking red-brown marking, and its petals slightly broader than sepals.

Key words: Bulbophyllum malipoense

摘要： 对中国兰科两新种———麻栗坡卷瓣兰( Bulbophyllum malipoense) 和赵氏蜘蛛兰(Arachnis zhaoi) 作了描述和绘图。前者与直立卷瓣兰( B. unciniferum) 相近, 区别点在于新种的假鳞茎聚生, 卵球形; 叶较小,长2～3.5 cm; 侧萼片较短, 长1.4～1.7 cm, 仅中部合生; 后者与窄唇蜘蛛兰(A. labrosa) 有亲缘关系,但新种花淡黄绿色, 无红棕色斑, 花瓣稍宽于萼片, 易于区别。
