SORGHUM, SPIRJEA. 
panicled racemes are very numerous and spread every way, so as to 
bring the one-sided flowers upwards ; rays half as long again as the ca- 
lyx. But this species is so variable that students generally endeavour 
to make several species of it. The serratures of the leaves are equal 
and unequal ; it is hairy or villose; and sometimes the racemes diverge 
but little. 3—6 f. S. 
pat'ula, (spread golden rod. O. y. S. 2]..) stem erect, glabrous; leaves 
oval, serrate, glabrous ; radical ones oblong-spatulate ; racemes pani- 
cled, spreading ; peduncles pubescent. Stem wand-like, angular and 
striate ; stem-leaves sessile, about an inch long, pointed ; the radical 
ones resemble those of the ox-eyed daisy ; racemes about an inch long; 
flowers rather large. 2 f. S. 
3. Racemes erect. 
bi-color , (white golden-rod. O. w. Au. 2J..) stem hairy; leaves oval, hairy ; 
lower ones serrate ; those on the flower branches entire, numerous, and 
small ; scales of the calyx obtuse. Racemes are short and compact ; 
rays white, somewhat numerous and shortish ; disk florets rather nu- 
merous. 2 — 4 f. S.

sacchara'lum. (broom-corn. y-g. Au. ©.) panicle somewhat whorled, spread- 
ing ; seeds oval; glumes covered with permanent soft ish hairs; leaves 
linear. From the East Indies. 6 — 8 f. 
10—5. SPERGULA. 22. 82. 
arveri'sis , (spurry. w. Ju. ©.) leaves whorled: panicles dichotomous ; pe- 
duncles of the fruit becoming reflexed. 6 — 10 i. S. 
20—5. SP1NACIA. 12. 28. 
Exotic. 
olera'cea , (spinach. J. ©.) fruit sessile, prickly or unarmed; leaves has-

album: 1—2 f.

Stem more or less u-oody. 
salicifo'lia, (meadow sweet, willow hard-hack. O. r. w. J. Tj.) leaves 
lance-ovate or obovate, serrate, glabrous ; flowers in panicled spreading 
racemes. Var. alba, has white petals, and generally the twig3 are red- 
dish. the small branches are generally killed by frost in the winter, as 
also of the next species. 2 — 4 f. S. 
tomenlo'sa , (steeple bush, purple hard-hack, meadow-sweet. O. r. Ju. Tj.) 
leaves lanceolate, unequally serrate, downy beneath : racemes in a 
crowded, suli-panicled, spike. 2 — 3 f. S. 
hypericifo'lia , (john’s-wort, hard-hack. w. M. I?.) leaves obovate, entire 
or toothed at the apex; umbels sessile. Cultivated. 3 f. 
opulifo'lia , (nine-bark, snow-ball, hard-hack. E. w. J. ??.) leaves sub- 
ovate, lobed, doubly toothed or crenate, glabrous ; corymbs terminal, 
crowded; capsules inflated; flowers trigynious. Wet. 3 — 5 f. S. 
Exotic. 
ulma'ria , (queen of the meadow. w r . Au. 2J..) leaves pinnate, downy be- 
neath ; the terminal leafets larger, 3-lobed ; the lateral ones undivided: 
flowers in a proliferous corymb. Stem herbaceous.
