SOME RUDBECKIA SEGREGATES. 177 
^R. AMPLECTENS. A slender perennial about 18 inches 
high with simple, sparingly hispidulous stem: the lower 
cauline leaves lanceolate-spatulate, entire or remotely denti- 
culate; the upper oblong, subcordate, clasping; all 3- 
nerved, somewhat reticulate-venulose, appressed-pubescent 
and acutish: peduncles about 6 inches long: involucral 
braets numerous in several series with appressed bases and 
the herbaceous free portion about 2 inches long, lanceolate- 
oblong, reflexed, strigose-hispidulous: rays 8 to 9 linear- 
oblanceolate, 1 inch long; disk, low, conical. 
Specimens collected by Mr. G. McCarthy (No. 28), near 
Rome, Ga.,in 1888; preserved in the United States National 
Herbarium under the name R. hirta. 
Quite unlike any other species of this group. Possibly 
nearest to R. truncata, small, of which no specimens have 
been seen by me; but it has not the prominently 3-nerved, 
linear-oblong to linear leaves attributed to that. Besides, 
its involucral bracts are broader, longer and more foliaceous. 
This plant may be identical with one Mr. Small has seen in 
the Columbian University [Chapman Herbarium], **col- 
lected many years ago at Rome, Ga.," but it is certainly 
distinct from his R. truncata. (Cf. Small. Bull. Torr. Club, 
xxv. 478.) 
/ R. DIVERGENS. Perennial, with divergently branching 
stem, about 3 feet high, sparingly beset with a fine, white, 
hirsute pubescence: basal leaves oblanceolate on slender 
petioles, the lower cauline spatulate-lanceolate, remotely 
serrate-denticulate; the upper linear-oblong, entire or re- 
motely serrate-denticulate; all faintly 3-nerved and strig- 
ose with fine white hairs: peduncles tortuous, about 12 
inches long, glabrate: involueral bracts short, about 6 lines 
long, oblong-linear or linear-lanceolate, hispid: rays 8 to 12 
linear-oblong, light yellow, fading greenish: disk depressed- 
globose of a light brown.
