TROPICAL AMERICAN COMPOSITAE. 27 
which, however, has white woolly stems and petioles, and broader as 
well as more caudate-acuminate leaves, which are 3-nerved from 
above the base rather than feather-veined.

Recent material, agreeing with this species in all essential characters 
of habit, inflorescence, florets, and achenes, as well as in the toothing, 
venation, and punctation of the leaves, still exhibits such marked 
differences in the rounded leaf-base closely sessile upon the stem as 
to present a decidedly exceptional appearance when compared with 
typical specimens. There is also a tendency on the part of some 
material now available to have much more coarsely toothed leaves 
than the type. To provide appropriate classification for these varia- 
tions the following varieties may be proposed. 
Var. typicum, foliis breviter serrato-dentatis (dentibus 0.6-0.9 mm. 
altis 3-5 mm. latis) basi cuneatis; petiolo 6-8 mm. longo.— CuBA 
Ramon de la Sagra (Gr.); in crevices of rocks at the Farallones, 
Wright, no. 1311 in part (Gr.). 
Var. apodophyllum, var. nov., foliis breviter serrato-dentatis 
(dentibus ut apud var. typicum) basin versus angustatis sed ima basi 
Totundatis arcte sessilibus vel cum petiolo brevissimo 1-2 mm. longo 
Munitis.— Cupa: base of coastal cliffs near Rio Yamuri, Oriente, 
6, 8 Dec. 1910, J. A. Shafer, no. 783 (type, Gr., N. Y.); margin of 
rivulets near Pinar del Rio, 3 Dec. 1860-1864, Wright, no. 1311 in 
part (Gr.). 
The plant of Shafer has sessile leaves, that of Wright has leaves of 
closely similar form, but very shortly petioled (petioles 1-2 mm. long).
