OF NORTH AMERICA.

deeply 5fid colorate villose, petals 5 equal ve- 
nose, stamens 20 inserted on a torus adnate to 
the base of calix, pistils 5 equal sessile, capsu- 
les 5 sessile tomentose monosperm. Habit of 
the paniculate Spireas . I have adopted this 
Genus and name on the suggestion of Lindley, 
who proposed to unite to it the next, but the 
habit is too different. Schizonotus appears to 
mean Split back and I do not know how it ap- 
plies unless the capsules open outside. 
673. Schizonotus discolor Raf. Spirea do 
Pursh, Torrey Dec. ariafolia Sm. Hook. Lind, 
b. reg. 1365. Leaves petiolate ovatoblong sub- 
lobate and laciniate serrate, white villose be- 
neath, flowers terminal paniculate racemose, 
pedicels and calix villose, petals oblong with 3 
veins — Origon region and Mts. A very pecu- 
liar shrub, quite different from my Thecanisia 
discolor 297, to which I refered by mistake the 
Sp. discolor of Pursh, flowers white, leaves cal- 
led elliptic by Smith, ovate by Pursh and Torrey 
but they are realy ovate oblong, 
f 674. BASILIMA Raf. 1815. Sorbaria subg, 
Ser. Schizonotus land. Cal. patent 5parted 
smooth not colorate, base acute, petals 5, sta- 
mens 15 to 20 inserted at the base of the calix, 
pistils 4 to 5 sessile, capsules 4 to 5 unequal ses- 
sile smooth monosperm. Large shrubs with 
{ the foliage of Roses and Sorbus , leaves alter- 
nate stipulate oddly • pinnate , folioles oppo- 
site sessile , flowers bracteolate paniculate or 
corymbose— This fine natural Genus is certain- 
ly more different from Spirea than Lowea is 
from Rosa ! it may be known at first sight by 
| its habit.
