The original specimens were collected by the writer in the 

 Ochlockonee River swamp, near Thomasville, Georgia, July 12- 

 22, 1895. 



Aster Camptosorus. 



Perennial, slender. Stems erect, 4-6 dm. tall, finely ridged, 

 slightly flexuous, green or purplish green, simple or nearly so, 

 glabrous, or very sparingly pubescent near the top ; leaves few, 

 the blades lanceolate, 6-15 cm. long, resembling the leaves of 

 Camptosorus rhisophyllns, attenuate from near the base to the finely 

 acute apex, entire, undulate, sometimes crisped, dark green, 

 smoth and lustrous above, paler and hispid beneath with a scat- 

 tered pubescence, the lower ones deeply cordate at the rounded 

 ear-like base, the upper ones subcordate or truncate, petioled; 

 petioles slender, villous, the lower ones nearly as long as the 

 blades, the upper about \ as long as the blades; heads usually 

 few; pedicels angled, bearing minute appressed bracts, scabrous 

 with short, stiff, spine-like hairs; involucres cylindric-campanu- 

 late, constricted at the middle (or turbinate in the dry state), 5 

 mm. high, the bracts linear-subulate, in 4 or 5 series, incurved, with 

 a narrow green midrib and green acute tip; corolla about 6 mm. 

 long; stamens and style glabrous; rays purple, linear-oblance- 

 late, I cm. long, slightly 3-toothed at the apex. 



In open woods, in and near the mountains, Georgia and Ala- 

 bama. September to October. 



A very curious and handsome species on account of the close 

 resemblance of its leaves to those of Camptosonts rhizophyllus. 

 Compared with its nearest relative. Aster Shortii, the new species is 

 more slender and, in addition to the Cainptosorus-Wko. leaves, and 

 the characteristic gradual attenuation from the base to the apex, 

 these organs are smooth, dark green and lustrous above. The 

 involucre of Aster Shortii is campanulate, whereas that of Astet 

 Camptosorus is cylindric-campanulate and constricted at the mid- 

 dle; the bracts in the new species are rigid, linear-subulate 

 and incurved, while those of Aster Shortii are rather thin, hardly 

 rigid and simply linear. 



Fine specimens were sent to me by Prof. Carl F. Baker from 

 Wright's Mill, five miles south of Auburn, Alabama. They were 

 collected on October 17, 1896. In addition to these I find an old 

 sheet in the Columbia University Herbarium on which are two 

 specimens collected in the mountains of Georgia by Mr. liuckley.
