The perianth, however, is only slightly thickened ; and the oblong 
(not cylindrical) capsule has straight valves, not twisted as in 
every true Jsotachis, and the male flowers are 1- (not 2- or 3-) 
androus.

appears to be not uncommon on the mountains of both islands. 
The following species, which I believe to be new, was found 
only once.
