114 | PITTONIA. 
a minute short, straight and closely appressed pubescence; 
the stem and inflorescence hirsute: calyx short, its lobes 
broadly ovate-lanceolate: nutlets as in the last as to form, 
but wholly light-gray, smooth. 
Confined, as far as I know, to the Arkansas Valley, in 
southern Colorado, where it occupies low subsaline clayey 
soils, being associated with such local species as Frankenia 
Jamesii, Oonopsis foliosa and certain shrubby chenopodia- 
ceous plants. 
OREOCARYA MULTICAULIS. Eritrichium multicaule, Torr. 
Marcy’s Report, 262 (as a synonym under E. Jamesit). 
Tufted perennial, twice or thrice as tall as the preceding, 
far less leafy, the stems stout and rigid, bearing more 
numerous and elongated spikes at and near the summit: 
leaves rather broadly oblanceolate; pubescence dense and 
somewhat tomentose: spikes appearing uniserial and unl- 
lateral: nutlets as in the last very smooth and shining. 
Frequent in the mountains of northern New Mexico and - 
Arizona; the type Fendler's n. 636, forming a part of Dr. 
Gray's Eritrichium and Krynitzkia Jamesii. A similar plant 
of western Texas may or may not be specifically identical 
with it. 
OREOCARYA ABORTIVA. Perennial, freely branching from 
the base, the short rather flaccid branches almost prostrate, 
3 to 5 inches long, leafy and floriferous throughout: herb- 
age somewhat silvery-silky, altogether destitute of other 
pubescence, except that the calyces and pedicels are finely 
and densely tomentose: leaves oblanceolate: calyx short, 
its lobes ovate-lanceolate: corolla-tube not exserted: nutlets 
usually solitary (3 of the ovaries abortive), strongly inflexed, 
the lateral outline subreniform with a stout stipe-like pro- 
jection from near the middle of the ventral edge, the dorsal - 
side polished and shining, smooth up and down the middle, 
but granulate along the very acute margins.
