﻿the body elliptical, wings 2" wide or more, fruit deeply 

 emarginate above and below, oil tubes 2-3 in the intervals 

 and 4 on the commissure; leaves ovate in outline, the 

 blade i£-2*' long, glaucous, thick, segments in the typ- 

 ical form nearly contiguous, very small, ovate to nearly 

 square ; old leaf-sheaths very persistent at the crown, the 

 green sheaths large, hyaline, nerved and usually colored; 

 root long, erect and fleshy. In other respects this plant 

 closely resembles C. montanus, having the same very thin 

 wings without any enlargement except next the seed and 

 all nearly equally developed. 



This is No. 1685 0± m . v Utah collection, and abounds 

 on the clayey and gravelly plains, valleys and lower hill- 

 sides throughout Utah and Nevada. 



A common form of this species is the variety monoceph- 

 alus Jones in Herbarium, having the umbellets densely 

 congested into a single close head, especially in fruit; 

 the leaves are much reduced and the segments contigu- 

 ous or imbricated. This form is C. montanus var. glob- 

 osus Wats, in King's report as to the fruit; it is also his 

 specimen from the Trinity Mountains, Nevada. The 

 type of this form is my specimen gathered at Terminus, 

 Utah, in 1890. To this I also refer a specimen from Can- 

 delaria, Nevada; also Palmer's specimen from Pocatello, 

 Idaho, probably Marsh's specimen from Ft. Wingate, 

 New Mexico, and possibly a specimen of Whipple's Ex- 

 pedition ticketed ' < California. ' ' All the above specimens 

 are in the National Herbarium, there being a duplicate of 

 my type in the Herbarium. 



Cymopterus Utahensis var. Eastwoods. 



Much more robust than the type with stems sometimes 

 16' high and occasionally somewhat caulescent; rays 

 1-2' long; fruit narrower and often much longer pro- 

 portionally, usually with thin wings i-if wide, generally
