摘要:

芒苞草的染色体数目为2n=38,染色体很小。染色体数目表明芒苞草与百合科蜘蛛抱蛋属
Aspidistra。和开口箭属Tupistra有一定联系,这也得到形态特征的支持。

Abstract:

 Chromosome number, 2n=38, is reported for Acanthochlamys bracteata
P. C. Kao for the first time. This number and the basic chromosome number
x= 19 imply the isolated position of this genus in monocotyledons. The affinities
are discussed based on the cytological evidence. It seems that Acanthochlamy is
more closely related to Aspidistra and Tupistra of the Liliaceae than to any of the
Amaryllidaceae.
