This interesting Orchideous plant, peculiar to Java * and 

 Ceylon, is referred by Dr. Lindley to the tribe Neottiea, and the 

 division Cranichidece, and is placed next to Mr. Brown's Austra- 

 lian genus Cryptostylis, to which it has perhaps too close an affi- 

 nity, as observed by Dr. Lindley, who however considered the 

 clinandriwn to be of a different form ; and t lie flowers are singu- 

 larly drooping or nutant in Cryptostylis, while they are erect in 

 Zosterostylis. My specimens from Ceylon appear to be quite 

 identical with those from Java, and there is, I fear, but one 

 species of the present genus, if genus it may be considered. 



Descr. Boot fascicled, consisting of a few elongated cylin- 

 drical tubers. Leaves long-petioled, ovate, rather sharply acumi- 

 nated, striato-nervose, the nerves connected by transverse veins. 

 Scape six or eight to eighteen inches high, much sheathed with 

 bracteas; the base and the petioles dark-purple. Spike lax,
