It has seemed best not to enter into a detailed discussion of 

 the foregoing specimens at this time, but simply to publish them 

 with the hope that observers who may run across similar speci- 

 mens will kindly communicate with the writer, who intends pub- 

 lishing a more elaborate essay on Liriodendron in the near future.

TWO SPECIES OF CHAMAELIRIUM 



By John K. Small 



More than ten years ago Dr. Britton collected a fruiting plant 

 of a Chamaeliriwn in the mountains of West Virginia. This 

 specimen was seen to be characteristic, particularly on account 

 of its large long-pedicelled capsules, but for some time nothing 

 else in our collections appeared to correspond to it very closely. 

 However, several years since, specimens from a number of locali- 

 ties have been obtained which have characters similar to those 

 possessed by the West Virginia plant and which together with 

 it doubtless represent an undescribed species. Therefore, the 

 genus Chamaelirium becomes a genus of two species, instead of 

 being monotypic as heretofore considered. 



Key to the Species 

 Capsules oblong or ovoid-oblong, 7-10 mm. long. 1. C. hiteum. 



Capsules obovoid or oblong-obovoid, 12-14 mm. long. 2. C. obovale. 



i. Chamaelirium luteum (L.) A. Gray. Stems 2-12 dm. 

 tall, those of staminate plants shorter than those of the pistillate,
