432. ALpDAMA UNISERIALIS. Gymnopsis uniserialis, Hook. 
Ic. Pl. t. 145; Torr. & Gray, Fl. 2. p. 317. Shady woods, 
On Comale Creek. June— August. In this and the allied 
species, united by De Candolle with Gymnolomia, H. B. K., 
under the common name of Gymnopsis, “the remarkable 
- manner in which the fertile achenia of the disk are inclosed 
in the pale of the receptacle, like those of the ray-flowers in 
Melampodium, seems fully to warrant the retaining for them 
Llave and Lexarsa’s generic name, Aldama.” Benth. Voy. 
Sulph. p. 116. 
433. Simsta (Barrattia: achenia calva glabra) cava. 
Barrattia calva, Gray & Engelm. in Proceed. Amer. Acad. 1. 
p. 40. Rocky hills and terraces, often under shrubby live oak, 
along the Guadaloupe and Pierdenales. July —( ctober. — 
Root fleshy, perennial. Size and number of the rays very 
variable. — The discovery of an allied species with a slightly 
biaristulate or bidentate pappus, as described in Plante Fend- 
leriane, p. 85., invalidates the character of the genus Bar- 
rattia, which we had established on this plant. Although 
the want of a pappus would refer it to a different Candol- 
lean division of Helianthee, it cannot now be generically 
distinguished from the genus Simsza. 
+ Vieurrra Brevires, DC. Prodr. 5. p. 578. Rocky-hill 
tops, on the Upper Guadaloupe. October. — The same form 
was collected in Western Texas by Mr. Wright. It agrees 
with the character in the Prodromus.
