448 SYNGENESIA FRUSTRANEA. 



Root perennial? Stefn two to three feet high, terete, glabrous, with very 

 numerous branches* Leaves linear, almost setaceous, glabrous, alternate, 

 sessile. Floivers terminal, somewhat fastigiate. Involucrum many leaved, 

 imbricate, the leaves narrow ovate, acuminate, equal, covered with glandu- 

 lar atoms and arranged nearly in two series. Florets of the ray small, yel- 

 low; of the disk numerous, yellowish. {Anthers bisetose at base, Nutt.) 

 Seed inversely conic, very acute at base, clothed with a glossy silken pubes- 

 cence, radiated, ofi the summit. Pappus short, expanding, obtuse, almost 

 truncate, the scales fourteen? generally equal to the rays on the summit of 

 the seed. Recex)tach nearly globular, cellular, the cells much deeper than 

 the included seed and pappus, somewhat hexagonal, with six acuminate 

 teeth, each of which from its structure is necessarily ^common to three 



cells. T- T> - 



Grows in the sand hills along the Altamaha; near Fort Barrmgton. 



Flowers in the autumn. 



As it is considered incorrect to change names once publicly given, I have 

 continued the name imposed upon this genus, however reluctant the gentle- 

 man to whom it is dedicated was to have it preserved. The two species, 

 however, are scarcely congeners; they differ in habit, in their involucrum, 

 and still more essentially in their seed and pappus. Indeed the bisetose an- 

 thers and deep cellular receptacle seem alone to unite them. To the former 

 I had originally given the name of FavQsa. The second, as far as imper- 

 fect specimens wUl permit me to describe it, offers the following characters. ^

AcTiNOSPERMUM. Tuvolucrum polyphyllum, foliis equalibus, duplici se- 

 rie imbricatis. Receptaculnm sub globosum, profunde favosum, celluhs 

 hexagonis, 6-dentatis. Semina obconica, summitate radiata. Pappus po- 

 lyphyllus, (12 — 14) cupulatim patens. 



When a mature head of this plant is first examined, the seed are seen 

 nestling in the bottom of the cells, exhibiting nothing but their radiated 

 summhs, and resembling in a striking manner some of the starry madre- , 

 pores. . ,
