180 PITTONIA. 
filaments are more deeply and sharply notched in these 
Tejon Mountain specimens than in any of the originals; 
and I have some misgiving lest as here presented the species 
may prove an aggregate. 
28. P. Hyacinruinus. Crinite-hirsute, though less so than 
P. crinitus, the plant comparatively low, slender, more 
nearly acaulescent, the scapiform peduncles only 3 or 4 
inches high: leaves only an inch long, with an apical cal- 
losity, but this obscured by the dense pubescence : corollas 
less than an inch broad, white or cream-color; petals 
cuneate-obovate, equalled by the very many stamens; fila- 
ments of the outer series not much shorter than the others 
but slightly obcordate, the others more narrowly spatulate- 
oblong and merely obtuse, all the anthers uncommonly 
short, merely elliptical and only subsessile, the short but 
- distinct suggestion of a stipe being present in all: ovaries 
glabrous, not known in maturity. 
Only a single specimen seen, that in U. S. Herb. from 
H. M. Hall, gathered in a meadow at 4500 feet altitude on 
San Jacinto Mountain, 19 May, 1897; distributed for P. 
crinitus, but very distinct; its stamens altogether peculiar. 
29. P. Antoninus. A foot high or more, the ascending 
leafy branches and firm upright peduncles of about equal 
length, the habit rather strict: small linear obtuse leaves 
and stoutish peduncles only lightly hirsute: flowers very 
small for the plant, little more than } inch broad ; petals 
narrowly obovate, pale cream-color within and also at the 
base outside, otherwise of a deep rose-purple: filaments very 
unequal, otherwise all alike, spatulate-linear, retuse under 
the linear anthers, and with the petals closely investing the 
mature fruit: carpels 12 to 15, barely 4 inch long includ- 
ing the short lance-linear stigmas, the joints about 6, 0b- 
viously and even rather strongly turgid-wrinkled.
