DIADELFIIIA DECANDRIA. 
Stem 3 — 4 feet high, branching, and with most parts of this plant more 
scabrous than any other species we have described. Leaves of a pale 
green, beautifully veined, hairy, and scabrous particularly on the under sur- 
face, very obtuse at base, common peduncles 2 — 3 inches long. Stipu- 
les dilated at base, large, obliquely ovate, acuminate, hairy and persis- 
tent. Bracteas ovate, lanceolate, hairy. Calyx 4 cleft. Corolla 3 times 
as large as the calyx, purple. Lomentum larger than in any other of our 
own species, 3 — 6 jointed, joints somewhat triangular. 
This is one of the species which has been referred to the H. Canescens 
of Linnaeus — The H. Canescens of Willdenow, is the H. Rotundifolium 
of Michaux, and our later botanists. I have among my specimens one 
sent me as the H. Canescens, according to Sir James Edward Smith, in 
which the leaves resemble this ver} 7 much in shape, size, and colour, but 
are thinner in their texture, less hairy, less scabrous, not so distinctly ar- 
ticulate, and the flowers apparently forming much more compact racemes, 
with bracteas nearly thrice as long as in our plant. 
Grows in dry soils. Very common. 
Flowers June and August.

H. caule repente, vi- 
ridi lineato; foliis sub- 
sessilibus, trifoliatis, 
suborbiculatis; racemis 
elongatis, laxe parvi- 
floris ; lomenti ar- 
ticulis lenticularibus.

Stem creeping, 
streaked with green ; 
leaves nearly ses- 
sile, trifoliate, nearly 
round; racemes long, 
with small scattered 
flowers; joints of the 
pod lenticular. 
If the Stem of this plant had been rigidly erect, it would resemble ve- 
ry much the H. ciliare of this sketch. If no error has crept into the des- 
cription of Michaux, his plant has not recently been seen by any of our 
botanists. 
Grows in Carolina. Michaux.
