AND GENERA OF PLANTS. 373 



Leptapoda *dmticulata; smooth; leaves linear-sublanceolate, denticulate, 

 acute, attenuated at the base, cauline broadly decurrent, uppermost sessile, 

 acuminate; sepals as long as the disk, lanceolate-linear; achenium smooth, pap- 

 pus deeply lacerate. 



Hab. In Georgia. L. Helenium; Decand., "Vol. V., p. 653. Leaves almost all equally nar- 

 row. Flower larger than the preceding. Rays more than twenty, broad cuneate, trifid and quad- 

 rifid. The peduncle conically enlarged under the capitulum. 



Leptopoda ^hrevifolia; smooth; radical leaves spathulate, subsessile, cauline 

 spathulate, denticulate, obtuse, slightly decurrent, uppermost lanceolate, en- 

 tire, acute; stem smooth, one-flowered; achenium pilose, turbinate; pappus 

 slightly lacerated. 



Hab. In South Carolina. A remarkable species, clothed distantly with leaves nearly to the 

 summit; radical ones very short, about an inch, nearly sessile, cauline leaves about two inches 

 long, half an inch wide. Flower large and showy, the rays few, (about twelve,) and much dilated. 

 Sepals lanceolate, shorter than the disk. Discal florets dark brown. Achenium covered with 

 brown, chaffy hairs. 



BAHIA. (Decand.) Trichophyllum. (Nutt.) 

 Bahia integrifolia; (Decand.) 



Hab.- Oregon and the Blue Mountains. Pappus about ten-leaved, nearly equal. 



Bahia multiflora. Trichophyllum multiflorum; Nutt. in Journ. Acad. Nat. 

 Sci. Philad., Vol. VII., p. 35. 



Bahia lanata; herbaceous and erect; lower leaves often bipinnatifid, segments 

 linear, equal, beneath and the stem canescently tomentose, above greenish; 

 flowers loosely corymbose, peduncles of moderate length. Trichophyllum lana- 

 tum; Nutt. Gen, Am., 1. c. 



Hab. With the above, of which it may be, perhaps, only a variety. The stem and leaves are 

 more slender, and the latter not so tomentose above; the peduncles are also fastigiate, and form a 

 loose corymb ; in the preceding the peduncles are very long and few. Pappus unequal. The speci- 

 mens described by Hooker, according to one sent from the author to Schweinitz, are weak ones, 

 in which the bipinnatifid leaves are not developed. 



Bahia tenuifolia; (Decand.) Very nearly allied to B. lanata. Perhaps only 

 a variety, with narrower leaves and shorter pedicels. 

 Hab. Common on the banks of the Oregon, in rocky places.
