SYNGENESIA FRUSTRANEA. 
Root perennial? Stem two to three feet high, terete, glabrous, with very 
numerous branches. Leaves linear, almost setaceous, glabrous, alternate, 
sessile. Flowers 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 on the summit. Pappus short, expanding, obtuse, almost 
truncate, the scales fourteen? generally equal to the rays on the summit of 
the seed. Receptacle 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. 
Grows in the sand hills along* the Altamaha, near Fort Barrington. 
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 F avosa. The second, as far as imper- 
fect specimens will permit me to describe it, offers the following characters. 
Actinospermum. Involucrum polyphyllum, foliis equalibus, duplici se- 
rie imbricatis. Receptaculum sub globosum,. profunde favosw», cellulis 
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 
summits, and resembling in a striking manner some of the starry madre- 
pores. 
GALARDIA. Fougeroux. 
Involucrum poly- 
phyllum, foliis subae- 
qualibus. Corollulce 
radii tripartitae. Pap- 
pus paleaceus, paleis 
8—10 aristatis. Re- 
ceptaculum convexum, 
setosum. 
Involucrum many 
leaved, leaves nearly 
equal. Florets of the 
ray three-parted. Pap- 
pus chaffy, chaff-8 — 10 
awned. Receptacle 
convex, bristly.
