appressed ; aclienia muricate and spiiiulose toward the apex, when mature 
shorter than the beak. — The specimens now collected have leaves 3-4' long 
and 5-6'' wide, slightly toothed and very obtuse. The involucral scales are 
certainly corniculate, as they are also in Hall & Harbour's plant : — no 
European specimens are at hand for comparison. Arctic America aiul La]^- 
rador to Alaska; Colorado, (357 Hall & Harbour;) Grreenland, Europe, and 
Northern Asia. Uintas, on a peak at the head of Bear River ; 12,000 feet 
altitude ; August. (723.) 
Taeaxacum phymatocarpum, J. Vahl. Dwarf, glabrous ; leaves 1-2' 
long, lanceolate, runcinate with rather sliort obtuse teeth, or nearly entire ; 
scapes scarcely exceeding the leaves ; heads very small, blackish ; outer 
involucral scales short, spreading; inner ones 8-12, 3-4" long, not cornicu- 
late, narrowly scarious-margined ; flowers very short ; mature aclienia not 
seen. — Described from Greenland specimens sent from Copenhagen with tiie 
above name. The present specimen, a single one only, is rather larger than 
those from Greenland, but is plainly the same plant. It is assuredly not T. 
lavigatum. It must be noted that both T. 2?alustre and T. phymatocarpum 
are considered forms of T. Dens-leonis by Dr. Hooker. Uintas, with the last, 
on a peak at the head of Bear River; 12,500 feet elevation ; August. (724.) 
Glyptopleuka^ makginata. — Sandy Artemisia plain in Truckce Pass of 
the Virginia mountains, in a cailon of the Trinity Mountains, and in Union- 
ville Valley, Nevada; 4-5,000 feet elevation; May, June. Also collected in 
1870 at St. George in Southern Utah by Dr. Edward Palmer, a form with 
less deveh)ped outer involucral scales. Plate XX. Fig. 11. A single branch ;
