Var. geraniifolium n. var. 
D. geranitfolium Ryvs. Bull. Torr. Club, 26: 583. 1899. 
Differs from the type only in having broader leaf segments, 
bractlets variable in size, and pedicels slightly more spreading. 
Charles valley, Arizona (f). 
29. D. camporum GREENE, Erythea, 2: 183. Nov., 1894. 
D. albescens Ryvs. Bull. Torr. Club, 26: 583. 1899. 
Roots fascicled, fleshy-fibrous: stem stout, erect, 1 to 3 feet 
high, pubescent throughout, especially above: a dense cluster 
of finely dissected root-leaves, and very few stem-leaves: ra- 
ceme long and simple, often dense; pedicels short, erect or ap- 
pressed: flowers white with blue spots on sepals, and sometimes 
tinged with blue or flesh color; spurs straight or curved, longer 
than the sepals; upper petals often tinged with yellow, lower 
ones 2-lobed, bearded: follicles pubescent, seeds scaly and often 
winged at the angles. Widely distributed. Manitoba to Ar- 
kansas and San Antonio, Texas, west to the Rockies (f). 
Var. Penardi n. var. 
D. Penardi Hutu, in Helios 10: 27. 1893. 
Flowers and leaves much like the type: upper petals toothed : 
seeds large, black, slightly scaly. Flagstaff Hill and Boulder, 
Colo., #de Huth. No type of this is known in America, but 
seeds of it have been sent to Columbia University by M. E. 
Autran, of the Boissier Herbarium. A specimen from Esmeralda 
Co., Neb. (W. H. Shockley, 1881), in Gray Herbarium agrees 
in characters of seeds and leaves, but notin color of flowers. It 
is an intermediate form between this variety and D. Geyer (ft), 
Var. macroseratilis n. var. 
D. macroseratilis Ryps. Bull. Torr. Club, 26: 585. 1899. 
Slender, leaf-segments fewer than in the type: flowers much 
the same. Represents the southern variation of the camporum 
eroup. “Hom Greene Co-,;) Nex...(7). 
30. D. scaposum GREENE, Bot. Gaz. 6: 156. 1881. 
Root a cluster of thickened, fleshy fibres: stem leafless as in 
D. nudicaule; radical leaves rather fleshy, pubescent, 3-parted, 
the divisions wedge-shaped, 3—5-cleft or toothed, the teeth end- 
ing in a calloused point: racemes many-flowered, pedicels as 
long as the deep azure blue flowers; spur incurved: follicles 3 
to 5; seed coat somewhat loose and wrinkled. Southern Utah 
and Arizona (f).
