This could be referred to P. perpulcher were it not for the strong contrast 
between its rather small flowers and the large showy ones of this. Then the 
dehiscence character is unique in the P. glaber group. Some of the red-flowered 
species of Penistemon, recently erected into a separate genus by Dr. GREENE, 
have anthers in which the upper portion of the cells remain closed and saccate, 
but none are known to the writers in the other sections of the genus. The 
SACCANTHERA section, of course, has anthers in which the base of the cell is the 
part that remains closed. 
ee ae ae four numbers are all representative, but the first is named as 
the type: no 9, Jarbidge, Nevada, July 9, 1912; no. 977, MACBRIDE, 
Twilight Gulch, ‘oupiee Co., Idaho, June 23, 1910 (distributed as P. speciosus 
Dougl.); 1774, House eek: Owyhee Co., Idaho, June 29, 1912; 2157, 
Bieroth’s Ranch (McDonald Creek), Nevada, August 2, 1912. 
PENTSTEMON PERPULCHER pandus, n. var.—Smaller than the 
species, the leaves more or less curved or arcuate: puberulence very 
dense, that of the stem extending to the rachis but not to the 
pedicels and calyx. 
No. 1884, July 2, 1912, on the high plains, near the ‘‘ Hot Hole” of the East 
Bruneau is the type 
Downingia brachyantha (Rydb.), n. comb.—Bolelia brachyantha 
Rydb., Mem. N.Y. Bot. Gard. 1:458. 1900. 
Downingia corymbosa (A. DC.), n. comb.—Clintonia corym- 
bosa A. DC. Prodr. '7:347. 1838. 
Because of some splendid specimens secured of these species in the field 
work of 1912, our attention has been called to the fact that in accordance with 
the action of the Vienna Congress (‘‘nomina conservanda”’) these species must 
be transferred. 
Erigeron elkoensis, n. sp.—Plant low, subcinereous with a 
rather dense short more or less retrose pubescence throughout, with 
a short simple or sparingly branched caudex clothed with dead leaf- 
bases: stems few, simple, decumbent-ascending, monocephalous, 
leafy throughout or often naked-pedunculate above, about 4-10 
cm. long: leaves numerous on the crowns, 2-4 cm. long including 
the petiole, oblong-spatulate, subacute, tapering to a narrowly 
winged petiole as long as or longer than the blade, inclined to be 
conduplicate; stem leaves similar, becoming smaller upward and 
linear: heads large, 20-25 mm. broad: bracts lance-linear, acute, 
unequal, one-nerved, in 2-3 series, the inner scarious-margined,
