96 SYSTEMATIC ARRANGEMENT OF THE SPECIES 
so much so, that Scheele has named it pulcherrima ; I therefore feel justified in the liberty I take with Choisy’s name 
in lopping off its negative in. — This is a wide-spread and quite variable species, extending from the United States to 
Brazil, always readily recognized by the structure of the fleshy white flowers, which consist of large convex cells, which 
make the surface appear rough and the margin crenulate ; these cells are on the surface sometimes elongated into oval 
or cylindric papillz ; inflorescence loosely paniculate or in some forms at last more compact ; lobes of calyx ovate or 
lanceolate, acute, of different lengths; lacinize ovate-lanceolate, inflexed at the acute point, erect or spreading, not re- 
curved ; scales large, broadly oval ; styles usually stout and very unequal, about as long as the conic ovary ; capsule 
enveloped by the corolla; seeds usually several, 0.6-0.9 line long, ery ovate, rostrate, rough, with a very short, 
oblong, transverse hilum. The following varieties may be distinguished :

minor, Engelm.! in Boston Journ. N. Hist. V. 223: flowers 1-— “uy lines long, on long pedicels, loosely 
panicled, with very short calyx.— On the Rio Grande, Berlandier! 865 & 2285 ; Texes, Lindheimer! 123, (in some 
of the distributed collections the numbers 123 and 124, both forms of this species, are transposed). — A papillose-hispid 
form of this variety is C’. verrucosa, a. hispidula Engelm.! Sill. Journ. XLIII. p. 341. C. hispidula, Engelm.! ib, 45, 
p- 75; DC. Prod. IX. 461; Texas, Berlandier! 956 & 2386 ; Drummond! 248; Lindheimer! 474; Wright! Some 
of these specimens by their larger flowers approach the next form.

Linnea, 21, p. 750: smooth or rarely slightly papillose ; inflorescence loose or sometimes more compact ; flowers vari- 
able in size, 1}-1? lines long, usually broadly campanulate ; calyx as long or longer than tube ; styles usually as long 
as ovary, rarely much longer; anthers and stigmas yellow or often purple. A form with very large and broad flowers 
is C. neuropetala, y. littoralis, Engelm. Boston Journ. 1. c. — On wet and dry prairies, from the sea-coast to the mountains,

Var. y. SUBNUDA: lower half of capsule enveloped by the tough remains of the corolla, upper part naked ; short 
styles divaricate. — “ Common on the overflowed islands of the Parana,” Brazil, Tweedie! in Hb. Hooker. 
> Var. 8. INTEGRIUSCULA : calyx shorter than the deeply campanulate tube of the corolla; laciniz erect ; scales 
triangular, acutish, thin, almost entire ; styles capillary, shorter than ovary. — Mendoza, on Ephedra, Gillies!
