Mimulus Mohavensis. Annual, a span or more high, viscidulous 
puberulent ; leaves oblong and lanceolate, acute and mostly a 
sile, 3-1 in. long; flowers alternate in the axils, short-peduncled ; 
corolla with a dark crimson eye and a pale border to the lobes, the 
latter numerously red-veined and glandular-ciliolate, 3-5 lines in 
diameter. 
On sandy slopes or dry washes along the Mohave river, Cal., between Dag- 
gett and Waterman, May 10, and opposite, near Calico ay 11, 1884. a 
Stems erect, sometimes simple, usually branching and ascend- 
‘ing, 2-5 inches in height; the leaves in all the specimens dis- 
covered are approximate and tinted a warm Indian red ; the. 
curious flowers peering out of the thick foliage display vivid con- 
trasts of dark crimson center bordered with light rose, the whole 
disk traversed with radiating and branching veins of blood red. 
Generally associated in groups, these little plants are quite at- 
tractive with their odd reddish-green leaves, strict habit and 
bright-eyed flowers. 
e specific name Mohavensis I have chosen in order to ub- 
lish more extensively the peculiar region where this novelty 1s 
found. The Mohave valley is noted for many rare forms including 
the types of four as yet monotypic and local genera—Mohavea, 
Canbya, Lemmonia and Parishella—while it is the headquarters. 
of several other odd genera of wider latitude, such as Monoptil- 
lon, Trichoptilium, Tricardia, Hesperocallis and Nicolletia, the 
latter, however, having a second species outside. 
n this connection it may be well to report the names apd 
localities of a few of the new species discovered during the same 
trip, and mostly in the same valley. he q
