649. Spire a bracteata Raf. levigata ? L. 
or of some botanists. Quite smooth, branches 
terete yellowish, leaves quite sessile oblong en- 
tire, base cuneate, apex obtuse cuspidate, some 
mixt ovate elliptic, panicle racemose, bracts 
ovate acute — Sibiria and New Sibiria, proba- 
bly a large shrub, branches thick, leaves 2 or 4 
inches long, one broad, base almost semiam- 
plex. panicle compound, flowers white race- 
mose. In my specimen some elliptical smaller 
leaves intermixt. Not quite answering to Sp, 
levigata see below, yet sent me as such. 
650. Sfirea cuneifolia Raf. Herff Quite 
smooth branches terete dark purple, leaves ses- 
sile cuneate entire, apex very obtuse cuspidate, 
panicles axillary and terminal racemose, bracts 
subulate — Origon and New Albion, a fine hand- 
some shrub disc, by Walton, quite different 
from last by red flowers, small bracts and large 
leaves 3 to 6 inches long, quite cuneiform or 4 ta- 
pering from end to base. The real Sp. levi - 
gata of Lin. is akin to both these sp. but it ap- 
pears to differ by lanceolate glaucous less ob- 
tuse leaves and white flowers, (some botanists 
call the cuneate leaves lanceolate ! which is the 
reverse tapering from base to end) while Smith 
blends the Sp. altaica with it, which I add for 
contrast. 
651. Spirea altaica Pallas fl. ross. t. 23. 
Stem terete redish, leaves fasciculate sessile 
cuneate acute repand glaucous, racemes pani- 
culate axillary and terminal, bracts lanceolate. 
— Altaic Mts. flowers white large, capsules 
large smooth 2sperme, leaves 2 or 3 inches 
long, not cuspidate nor obtuse ; thus quite dif- 
ferent from the two last. Is it the real levigata 
of Linneus as deemed bv most of botanists?
