‘SPECIES OF LAPPULA 545 
by a smooth depression from the pilose crest: nutlets 3-4 mm. 
long, the marginal prickles united at base for about half their 
length, all glochidiate ; dorsal surface with a faint central ridge, 
muriculate, and bearing 6-12 glochidiate bristles half as long as 
the marginal ones; inner face smooth, the oblong scar central. 
Salmon River bluffs, Idaho, altitude 2500 feet, 2 July 1895, 
L. F. Henderson, 3006. Type in the U.S. National herbarium, 
no. 231836. 
I would also refer here two specimens from Boise, Idaho ; one 
collected by A. Isabel Mulford, July and August, 1892, which in 
the Gray herbarium specimen is mixed with LZ. floribunda; the 
other collected June 1881, by Dr. 7. Z. Wilcox and referred by 
Dr. Gray to L. hispida. The fruit of the Wilcox specimen is 
rather larger than that of the type, being 5 mm. long.

Echinospermum ursinum Greene; Gray, Proc. Am. Acad. 1'7: 
224. 1882. 
No other material has been seen of this species except that 
which was before Dr. Gray. Fendler 633 from New Mexico re- 
ferred here by Dr. Gray is very probably a distinct species unde- 
Scribed. Parry’s 172 collected in South Utah in 1874 is a form 
of Z. caerulescens.

Pressed short hairs with papillose bases; basal leaves spatulate- 
oblanceolate, obtuse, petioled ; cauline oblong-lanceolate, acutish : 
branches of the inflorescence with 15-25 rather densely crowded 
OWers : calyx hispid, the ovate-oblong lobe obtuse: corolla blue, 
the tube barely exceeding the calyx, the limb 5 mm. broad; ap- 
Pendages broader than long, papillose, the protuberance small : 
fruit ’5 mm. long on recurved pedicels about as long: nutlets with 
the Marginal prickles united into a wing, all glochidiate ; back 
smooth with a prominent heel ; ventral surface smooth, the trian- 
gular scar central,
