ROSACEAE. 
Prunus pemissa, Walp.—My specimens were obtained doubtless from 
near where Fendler secured his. In some of its forms too close to P. 
serotina. No. 400 of the Colorado collection I have doubtfully assigned to 
this species —Nevada and Utah. 
Neiu1a* paucirtora, Benth. & Hook. (Spirea opulifolia, y. pauciflora, 
T. & G. Fl. 1, p. 414.)—Differing from Neillia opulifolia (Benth. & Hook.) in 
smaller leaves, fewer flowers (5-10) to the corymb, and having usually less 
than four hairy carpels, and one to two mature ovaries. Still, however, it 
is quite variable. 402, from Mount Graham, has large leaves, and 53, from 
Santa Fé, has as high as 14 flowers to the corymb. 
Sprr#A MILLEFOLIUM, Torr. (Pacific R. R. Report, 4, 83, t. 5).— 
“ Woolly-tomentose; leaves oblong-lanceolate in outline, pinnate, with many 
- pairs of small leaflets, pinne pinnatisect, or parted, oblong-linear, densely 
crowded with the very minute oblong divisions; flowers racemose-panicu-
