22 PITTONIA. 
pairs lateral and terminal, very short-peduncled: largest sepal 
elliptical, the others nearly linear, all acute, moderately hispid 
except at tip: corolla small, very little exceeding the calyx; | 
stamens wholly included: capsule round-oval, very villous above 
the middle. 
The type specimen of this very well marked species is one of 
two specimens sent me by Mr. Parish, form San Bernardino, 
California, in 1891, under the name of P. distans. The other 
Specimen, with its finely cut foliage and short divaricate spikes, 
may well be what the label indicates; but this other specimen 
is extremely different, with its broad ample foliage and elongated 
erect spikes in numerous pairs, 
I next subjoin the characters of several species that have been 
placed, in the herbaria, with P. Davidsonii and often under that 
name. All are annual.

P. ALDERSONIT. Low, only 3 to 6 inches high; herbage pale 
and soft with a fine pubescence, hispid hairness wanting: leaves 
all simple and entire, acutish, 1 inch long, but the petiole much — 
longer, dilated and as it were winged below the middle: sepals _ 
oblanceolate, obtuse, softly hirsute: corollas open-campanulate, : 
twice the length of the calyx. 
Collected at Witch Creek, San Diego Co., Calif., in 1893, by 
R. D. Alderson, and distributed for P. Davidsonii, from which 
it is now seen to differ much in foliage, pubescence, calyx, etc- 
P. Conepont. Branched from the base and widely spreading, 
only very sparingly leafy; herbage almost hoary with a coarse 
pubescence which is sparse and spreading on the branches, dense 
and appressed on the foliage; leaves simple, entire, elliptic, short- 
petiolate: racemes lax, solitary or in pairs: sepals linear, hispi- 
dulous, in maturity twice the length of the ovate capsule: 
corolla campanulate, twice the length of the calyx, apparently 
light-purple. 
Buckeye, Mariposa Co., Calif., 25 April, 1895, J. W. Con g don 
who distributed it for P. Aumihs, which it little resembles,
