164 PITTONIA. 
family. The habitat is said to be sandy ravines near the sea- 
shore on the east or peninsular side (Cedros Island being 
opposite) of the Bay of Sebastian Viseaino. I have thought 
it well to dedieate the genus to the memory of that celebrated 
early Spanish discoverer whose name is permanently associ- 
ated with the geography of the region. 
CEDRONELLA RUPESTRIS. Shrubby, erect, slender, 1—3 feet 
high, with numerous divergent branches; pale-puberulent 
throughout, and closely punetieulate; leaves an inch long or 
more, almost sessile, narrowly lanceolate, entire, with a promi- 
nent midvein and an obscure nerve running parallel with it 
on either side: inflorescence terminal, also lateral at the ends 
of the branches, few-flowered and loose: calyx not colored, 
the teeth triangular, acute, one fourth the length of the tube : 
corolla an inch long, pale rose-color.—?C. cana, var. lanceo- 
lata, Gray, Syn. Fl. Supplement, 462. 
Colleeted by myself at Mangos Springs, near Silver City, 
in the southern part of New Mexico, 1880, also at the same 
place later by Dr. Rusby. I assume, with a little doubt, that 
this is what the late Dr. Gray founded his variety upon. But 
it is a most distinct species, inhabiting rocky ledges, being 
shrubby, and of an altogether bushy habit and aspect. 
‘'TRITELEIA HENDERSONI. Leaves 2, 8—10 inches long, the 
solitary scape of scarcely more than equal length: pedicels 
6—8, slender, 1—2 inches long: perianth funnelform, 3 inch 
long, cleft to the middle, yellowish, with purple-veined and 
-tinged segments : filaments equal, joined to the entire length 
of the perianth-tube, free above and subulate-dilated, bearing 
the anthers above midway of the segments: anthers blue, 
1 line long, obtuse at both ends, fixed by the middle: ovary 
on a stout stipe of more than its own length. 
Glendale, Oregon, June 30, 1887, Thomas Howell; the 
specimens distributed under the name Brodiæa Hendersoni.
