94 PITTONIA. 
Frequent in subalpine moist meadows among the moun- 
tains about the headwaters of the Humboldt River in eastern 
Nevada. A graceful subscapose species, quite recalling the 
Californian D. uliginosum both in aspect, and its swampy 
habitat, yet in no degree related to that species. In all 
probability it is the D. depauperatum of the Botany of Clar- 
ence King's Expedition, for it seems to be the only Del- 
phinium of the region referred to; but the author, or authors, 
of that volume did not describe their plant, but only repeated 
Nuttall’s character of his D. depauperatum, to which this 
is far enough from answering. 
DELPHINIUM Hansent. D. hesperium var. Hanseni, Greene, 
Fl. Fr. 304. To the character ascribed in the place cited 
must be added: seeds white and bur-like by a dense coat of 
prominent flattened and somewhat scale-like processes: ra- 
cemes in the type short and dense: spur of the calyx rather 
long, only slightly eurved. Nearly allied to this, and con- 
fused with it in the Flora Franciscana, is a variety or sub- 
species which may take the name arcuatum, and be dif- 
ferentiated as follows: spiciform raceme long and loose: 
sepals much broader; spur short, strongly curved: radical 
leaves, and especially the petioles, hispid-hirsute: seeds as 
in true D. Hanseni. The discovery of the marked peculiarity 
of the seeds, on account of which the plant must needs be 
separated from D. hesperium altogether, is due to Miss East- 
wood, who was first to obtain the species in fruit. 
DELPHINIUM COGNATUM, Greene, of page 14 preceding, is 
probably the plant which should stand for the type of Dr. 
Gray’s D. Andersonii, which species is certainly a mixture 
of the grumose-rooted D. decorum var. Nevadense, Wats., an 
the fibrous-rooted species of the Nevada deserts. Since the 
author credits his species with fibrous-roots, we must, of 
course, take as typical the one which answers to that part of 
the description. In the Flora Franciscana I very inexcus-
