branches. Bracts mostly 3-cleft and as long as the pedicels. Calyx-lobes triangular- 
acuminate, growing longer and more slender with age, as in the S. Oregana. Petals 
neatly half an inch in length. It is a smaller and more slender plant than the 8S, Ore- 
gana. A full account of this genus is given in the subjoined note (p. 18 et seq.). The 
species have been for the most part referred to Sida, with which they have little in com- 
mon excepting the naked calyx. 
80. S. canpipa (sp. nov.): caule folioso inferne petiolisque parce hirtellis; foltis 
inferioribus et radicalibus orbiculatis sinu clausis 7-lobatis levibus ciliolatis, lobis cuneato- 
rotundatis grosse 3—5-crenatis incisisve, supremis 7- (floralibus 3-5-) partitis, segmentis 
lanceolatis integris; stipulis ovalibus; racemo brevi compacto glandulosi-tomentoso ; 
pedicellis brevissimis ; calycis tomentosi laciniis ovatis obtusiusculis ; corolla alba ; coccis 
levibus glabris angulo interno apiculo pubescente mucronatis. — Gray, Gen. Ill. t. 224. 
— Along Santa Fé Creek; June, July. Plant 18 inches high; the’stems simple from 
a perennial creeping rhizoma, glabrous except the scattered bristly hairs below: the 
smooth leaves almost exactly orbicular in circumscription, 2 to 2+ inches in diameter. 
Raceme spicate, only 3 or 4 inches long, densely flowered, not elongating in fruit, leafy 
at the base, glandular-downy, as well as the calyx; the upper bracts linear or lanceolate 
and little longer than the pedicels: the latter are spreading, shorter than the calyx, 
2 to 3 lines long. Petals apparently pure white, obovate, over half an inch long. Sta- 
mineal column slender, hairy (as in the other species), the phalanges less distinct than in 
_ the foregoing. Anthers blue. Carpels 9 or 10, cochleate-reniform, minutely apiculate 
at the inner angle. — A remarkable variety of this fine species, having larger cauline 
_ leaves with a very open sinus, and subsessile flowers, was gathered by Col. Fremont in 
his third expedition, probably in the Rocky Mountains.
