the tube: corolla white or pinkish with yellow center, sur- 
passing the calyx and about 2 lines broad, the lobes obovate, 
obtuse. 
In pine woods of Graham's Park, Rio de los Pinos, at 
7,800 feet, southern Colorado, 12 May, 1899, C. F. Baker. 
The species bears more resemblance to real Old World A. 
septentrionalis (not believed by me to exist in this country), 
than do any of the plants of the far West and North that 
have been referred to it. Iis habitat, in its native southern 
latitude, is not even subalpiue. The short pedicels aud 
contracted umbel appertain, it may be, to young and merely 
flowering plants. Other specimens, obtained by Mr. Baker 
from along irrigating ditches, and being in fruit, exhibit 
long pedicels and a loose diffuse umbel; and the plants 
are larger every way than in those from the pine woods 
above; a natural result of generous nourishing. 
ANDROSACE ASPRELLA. Perhaps annual or biennial, the 
root very slender, sustaining a small rosula and several 
low slender scapes with lax few-flowered umbels, the pedicels 
nearly as long as the scapes: leaves à inch long, spatulate 
to oblong-linear, entire, glabrous beneath, nearly so above, 
the margins sparsely ciliolate; scapes, bracts, pedicels, and 
even the calyx rough with short hairs, these seldom simple, 
usually divaricately forked, much coarser than the pubes- 
cence of allied species: calyx broadly obpyramidal, the 
broadly or triangularly subulate teeth almost as long as the 
tube. 
Rogue River Valley, Oregon, 16 July, 1887, Thomas 
Howell; distributed for. A. septentrionalis, and with the 
habit of A. diffusa, but exhibiting the best of specific char- 
acters. 
PHYSALIS POLYPHYLLA. Perennial, the erect freely 
branching and very leafy stems 6 to 10 inches high, from 
apparently horizontal roots; the branches and main stem
