CORYMRIFERES. 
Of this extensive tribe of plants, I have yet a 
crowd of new and interesting N. G. and sp. 
some of which have been given in the first part, 
I must here confine myself to some of the most 
striking, waiting to see what Decandole and 
Torrey will do ; good monographs of the G. 
Aster, Solidago, Erigeron, Helianthus, Coreop-

and blended are much wanted, and may be un-

910. NEACTELIS Raf. Flosculose, peri- 
anthe in triple series adpressed not ciliate, inner 
colored, phoranthe convex with subulate chaffs, 
floscules with tube and limb terete tubular, 
5dentate, stamens and styles inclosed. Seeds 
without crown, linear compressed. Leaves op- 
posite, stem uni jl ore nearly naked — A singu- 
lar Genus with habit of my G. Discomela ( 1 825) 
and the Helianthea with naked stems, yet not 
radiate ; perhaps blended with them as did Col- 
lins, and as Elliot blended my G, Anactis with 
Aster, being his A . discoideus . Radiate and 
flosculose plants are always of different Genera 
even Senecio and Jacohea . Mv name means 
Sun without rays . By the seeds near to Es- 
peletia, Heliopsis, Helepta, Acmella & c. 
911. Neactelis strigosa Raf. Helianthus 
apetalus Coll, herb, stem virgate grooved nearly 
smooth and naked uniflore, lower leaves oppo- 
site oblong acute entire, thick strigose on both 
sides by white tubercles ending in a bristle, a 
few short alterne leaves higher up ; perianthe 
with segments ovate lanceolate acute— in 
Florida collected by Kinn ? stem 15 inches, 3
