﻿New Plants from Western North America.— I, 



By A. A. Heller. 



(Plates 338-340.) 



The following species, with one exception, were collected by 

 Mrs. Heller and myself, either in Nez Perces county, Idaho, dur- 

 ing the season of 1896, or in New Mexico, in the vicinity of Santa 

 Fe, in 1897. Besides these, a number of others, still undescribed, 

 have been distributed, and it is now the intention to publish them 

 as speedily as possible. The type specimens of all new species 

 described in these papers, are deposited in the herbarium of the Uni- 

 versity of Minnesota. The drawings for the illustrations were 

 made by Mrs. Heller. 



Calypso occidentals (Holzinger) 



Calypso bulbosa forma occidcntalis Holzinger, Cont. U. S. Nat. 

 Herb. 3 : 251. 1895. 



This western plant is very similar to the eastern C. bulbosa, but 

 differs in several points which seem to be constant. The color of 

 the bunch of hairs on the lip is white, instead of yellow. These 

 hairs also appear to be less numerous, straighter, and more slender. 

 The lip also is usually longer, and more slender in proportion. 

 So far as I have been able to ascertain, there is no record of speci- 

 mens with yellow hairs from any point west of the Rocky moun- 

 tains. The fact that these hairs are longer and fewer, is also noted 

 in an account of certain Californian plants.* The plant is certainly 

 as worthy of specific rank as many species now recognized by 

 all, and is distinct geographically. 



Collected in deep, damp woods, along the Sweetwater, and on 

 the Craig mountain plateau, Nez Perces county, Idaho, June to 

 July, 1896, no. 3185. It is the same as no. 211 of Sandberg, 



MacDougal and Heller, collected at the same place on the Sweet- 

 water, in 1892, which is the type locality. It has been collected 

 at different places in Idaho, Oregon, Washington and California.
