ACANTHUS. 
flat ciliate, 2 pistillate flowers on the peduncle 
of the staminate flower. — In Louisiana, stem 
2 feet, flowers axillary only 3, authers almost 
in a spike. No figure. 
8. A. fruticulosa Raf. fl. Louis. 368. Shrub- 
by, branches divaricate, rufous tomentose, 
leaves petiolate ovate dentate : involucres invo- 
lute unequally dentate, a single pistilate and 
staminate flowers. — In Louisiana, stem 2 feet, 
with many slender branches, flowers axillary 
geminate. No figure. 
These two last species neglected by our Bo- 
tanists, are very distinct and approximate to 
the tropical species. Linneus states his A , 
virginica to grow in Jamaica and Ceylon, 
quoting the figures of Brown and Plukenet ; 
they must apply to other kinds, which may be 
called 
9. A. jamaicensis Raf. Fruticose, leaves 
ovate-lanceolate longer than petiols, serrate, 
scabrous : Spikes axillary, involucre multifid 
(Lin.) but cordate crenate (Brown) — In Ja- 
maica and perhaps in Florida, shrub 4 to 5 
feet high. See Brown, Lunan and Jamaica au- 
thors. Very different from all ours, perhaps 2 
Sp.there. 
10. A. zeylanica Raf. In Ceylon, certainly 
more distinct yet, but I have no materials at 
hand on it. 
ACANTHUS of Lin. Genus foreign to N. 
America, the following doubtful species may be 
a Pedicularis. 
A. rubens, Raf. fl. Louis. ' 104. Leaves 
inerme soft, clasping, broadly sinuate. — In 
Louisiana near New Orleans ! A. mollis Ro- 
bin. Stem 3 to 4 feet, flowers pale red. 
c Var Minor smaller, leaves deeper sinuate, 
flowers remote
