long, rather wider than their length, more or less deeply toothed or lobulate. Heads 
1-14 line diam., several-flowered, 20-30 in a dense corymb. Disc-fl. glandular, 
12-15; ray-fl. 5-6, with very short, imperfect corollas. 1 have not seen any speci- 
men of Lessing's Schistostephium flabelliforme, but, by description, it can hardly be 
different from Tanacetum argyreum, DC. 
_ 2.8. rotundifolium (Fenzl. Ms.) ; herbaceous, erect, tall, branched ; 
stem and branches terete, villoso-tomentose ; leaves on slender petioles, 
those of the sterile twigs sub-opposite, the rest alternate, roundish, 
3-7-nerved, coarsely toothed, closely silky on both sides ; upper branches 
ending in many-headed, branching corymbs; heads globose; inv.-scales 
lanceolate, acute, silky, shorter than the flowers ; achenes without pap- 
pus ; marginal female flowers with short, bilabiate corollas, and flattened, 
pilose achenes. Zanacetum rotundifolium, DC. / 1. c. 133.

2-3 ft. high, robust, densely leafy. Petioles } inch long, very slender. Leaves 
7-1 inch long, and equally wide, truncate or broadly cuneate at base, toothed above, 
the teeth shallow, very broad, mucronate. Fl. branches in a terminal panicle, each 
corymb 10-20-headed. ecept. conical. Some of the central flowers abortive. 
3. 8. crategifolium (Fenzl, Ms.); stem half-shrubby, branched, erect 
or ascending ; branches appressedly silky-villous ; leaves sessile with a 
stipular lobe at base, pinnatifid, the lower lobes short and simple, lan- 
ceolate, acute, the upper oblong, often toothed or trifid, all copiously 
silky, especially beneath ; fl. branches shortly naked at top, bearing a 
few-headed corymb ; pedicels long or short; heads globose, many- 
flowered ; inv.-scales pluriseriate, silky, linear, acute ; marginal-flowers 
female, with short corollas, and flattened, pilose achenes. Zanacetum 
crategifolium, DC. l. c. 134. Also 7’. consanguineum, DC. l. ¢. fide sp. ex

A robust, branching, half shrub, 1-2 ft. high, with copious, straight, silky, whit- 
ish pubescence. Leaves 1-14 inches long, deeply pinnatifid or pinnati-partite, when 
young on both sides silky, the older ones becoming naked above, lobes 1-14 line 
wide, 2-3 lines long. “Inv. somewhat silvery. Heads 4-12 in a corymb, 2-4 lines 
across. I find marginal female flowers in Drege’s specimen of “ 7. consanguineum,” 
and therefore venture to combine that with the present; the size of the fl.-heads and 
length of pedicels are characters too inconstant to be trusted. The marginal fl. are less 
clearly bilabiate, and their teeth much smaller than in the other species. 
LXIV. ARTEMISIA, Linn. 
Heads discoid, homo- or heterogamous, the marginal flowers in one 
row often female, 3-toothed, with a long, exserted, bifid style; disc ft. 
5-toothed, hermaphrodite, or abortive, or male. Jnvol. imbricate, the 
scales with membranous borders. ecept. without palex, flattish or 
convex, naked or hairy-fimbrilliferous. Achenes obovate, with a small 
epigynous disc. Pappus none. DC. Prodr. 6, p. 93. 
A. very large genus of bitter or aromatic herbs or suffrutices, almost exclusively 
natives of the northern hemisphere. Leaves alternate, variously pinnatisect. Heads
