NEW SPECIES OF POLYGONUM. 199 
not manifest except near the margin, there very promi- 
nently raised, light-colored and conspicuous, in form and 
arrangement recalling the young sori of some simple- 
- fronded Asplenium; cauline leaves narrowly linear, sessile, 
their long ocreæ ending in a short and cyathiform scarious 
margin: spikes round-ovoid, } inch high: flowers white, 
their bracts ovate, acuminate. 
The perfect type of this is Mr. Flodmans’ n. 386, as in the 
U. S. Herb., from Spanish Peaks, Madison Range, Montana, 
14 July, 1896. Rydberg and Besseys’ n. 5357, from Indian 
Creek in the same State, 1897, is evidently of this species. 
The little cup-like margins of the ocreæ are peculiar. 
P. BERNARDINUM. Stems upright, tufted on a stout con- 
torted and rather coarsely fibrous-coated root, themselves 
about a foot high, stout, but the leaves are small, the basal 
scarcely larger than the cauline and 2 or 3 inches long in- 
cluding the short petiole to which the blade is somewhat 
rounded, scarcely acute at apex, thickish as to texture, 
Veinlegs, glabrous, inclined to be revolute: spikes ovoid, 
about # inch long; flowers white; floral bracts ovate, 
acuminate. 
Bluff Lake, eastern base of the San Bernardino mountains, 
California, at 7,400 feet altitude, S. B. Parish, 24 June, 
1894. With its stout sheathed stems and remarkably small 
foliage the plant is reedy-looking by the side of others of 
similar height. 
P. GLAsTIFOLIUM. Stout and tall from a short thick 
knotted or contorted root: lowest leaves erect, often a foot 
long or more, on a long stout petiole; blade elliptical to 
oblong, 5 to 8 inches long, the cauline oblong-lanceolate, 
Sessile, 2 or 3 inches, the upper face of all smooth, some- 
what glossy, finely reticulate, the lower face glaucous and as 
if lepidote-puberulent, the broad flat midvein 3 to 5-striate ;
