foiiose leaves as high, flat convex be- 
neath at the base not vaginate, end 
obtuse. Spikes united and thick, 
upper subequal, between them a ca- 
ducous bract ovate lanceolate mem- 
branaceous. Maryland to New York 
and Canada. T. latifolia of the 
Northern botanists. Stem only 3 or 
4 feet high spikes 4 to 6 inches long, 
one inch thick, lower spike brown 
very dense and thick. 
These 3 sp. are very distinct.

4 10. Two New Genera of Umbel- 
liferous Plants from Kentuc- 
ky. 
These two singular plants were 
discovered in 1822, one Orimaria 
is near to Buplevrum having entire 
leaves, the other Streblanthus is 
near Eryngium having opposite 
leaves and capitate flowers. 
1, Orimaria. Pistil oblong, seeds 
linear smooth black, angular behind . 
Calix entire. Petals 5 white minute 
base with a foveole or small round 
pit, end retuse involute, ti p adnate 
inside. Stamens 5 small anthers 
subsessile round. Stigma 2 sessile 
small. General Involucre triphy- 
lous subulate, partial 5 phyllous, 
folioles equal elliptic acuminate sca- 
riose trinerve. Annual herbs smooth 
dichotomous , leaves alternate sessile 
entire linear . 
Orimaria jiliformis . Raf. Stem 
filiform flexuose, dicho tamely branch- 
ed, leaves remote linear— filiform, 
acute, lower nearer with broader re- 
tuse tip. Umbels terminal 3-4fid, 
umbel lule 3-6flore, peduncles une- 
qual, shorter than involucres. 
In the barrens or glades of West 
Kentucky, rare, vernal. Stem 4 to 
8 inches. Habit of a grass. Flow- 
ers white minute hidden in the invo- 
lucre. Different from Buplevrum 
by the petals and seeds, the foveole 
of the petals has suggested the ge- 
neric name. 
2. Streblanthus. Flowers mo- 
noical in separate heads. Involucre 
4-5 phyllous, folioles linear unequal, 
phoranthe cylindrical naked. M. fl. 
in ovate heads, calix 4 fid, pistil ad- 
herent abortive. Petals none. Sta- 
mens 4 subsessile very small. F.fh 
in oblong heads, calix 4 toothed per- 
sistent, pistil obovate punctate. Pe- 
tals none. Styles 2 filiform persis- 
tent, stigmas capitate. Fruit bipar- 
tite, crowned, 2 seeds convex scrp- 
biculate behind. Annual herbs pros- 
trate , , leaves apposite simple heads 
axillary . 
Streblanthus auriculatus Raf. 
Smooth prostrate, stems filiform 
flexuose, leaves opposite subsessile, 
lower petiolale, ovate lanceolate, 
base with 1 or 2 auricles, end acute, 
heads axillary solitary pedunculate. 
A striking N. G. of the group of 
Eryngides by its monoicai apetalous 
tetrandrous flowers. The Er. cer- 
vantesi of Mexico, ErJenue of Caro- 
lina and Er, jloridanum of Torrey’s 
herbarium come nearer to it and per- 
haps belong to this G. Found in 
the glades of W. Kentucky. Esti- 
val, heads somewhat bluish. Stems 
a foot long, leaves entire or with 
some notches, auricles unequal when 
Streblanthus means deceitful 
2 
flowers, since they resemble Eelip - 
ta r Scabiosa and many Rubiacea.

111. On 12 N. Sp. of Plants from 
Illinois, &c. 
By C. S.Rafinesque. 
They were chiefly discovered in 
1818, or given me since by Dr. Mul- 
ler and Dr. Ward. 
1. Collinsia purpurea Raf. 1818. 
Stems simple pauciflore, leaves re- 
mote, lower obovate, upper linear 
acute, peduncles equal to flower, 
calix campanulate, corolla purple, 
upper lip short...Annular and vernal 
like the C, bicolor or verna, on the 
bank of the Wabash, only 3 to 4 
inches high. 
2. Plant ago gonophylla Raf. 1818 
Smooth stemless, leaves petiolate 
ovate oblong acute, margin unequal- 
ly angular, 7 nerved. Scape round 
spike slender elongate, flowers scat- 
tered lax ovate globose, bracts and
