234 MR. GEYER’S ROCKY MOUNTAIN PLANTS. 
the Nez Percez Indians. June. (n. 414.)— Of the Genus - 
of this I am exceedingly doubtful. The immature fruit 
and leaves are not unlike those of some Angelica ; but there 
are no large sheathing bases to the petioles. My speci- 
mens are very imperfect: they consist of a fusiform root, 
clothed, especially above, with dense, coarse, long fibres, 
the remains of former petioles :—there is only one root leaf; 
the main petiole of which is about a span high, semiterete, 
channelled, striated, glabrous, as is the whole plant; this 
divides into 3 at the top, and each of those again into 3, - 
bearing generally 5 oblong-ovate, membranous leaflets, 
opposite and slightly petiolate :—the extremity of a flower- - 
ing branch has a whorl of about four pinnated and la- 
ciniated, sessile, small (2-3 inches long) leaves, within 
which is an umbel of 6 rays, the centre ray is twice, as 
long and 4-5 times as stout as the others, each bearing an 
umbel of many petiolated umbellules of fertile flowers, 
- yellowish white, the stylopodia very large, much broader 
than the ovary: the other 5 rays are sterile, (having . mo 
trace of pistil), and are each terminated by a com- 
pound sterile umbel, the whole forming a whorl around 
the central ray, whence Mr. Geyer’s specific name, There 
-is besides a separate fertile umbel, with very i 
deeply sulcated, obovate fruit. The umbels ani umbel 
lules have no involucral scales. ; As
