ROBINSON. — ON CERTAIN EUPATORIEAE. 193 
men upon which Dr. Watson founded his species, becoming a striking 
feature, seems to be accompanied by no other differential character 
and is, as shown by later collections, by no means constant. 
Trichogonia capitata (Rusby), comb. nov. Hupatorium capitatum 
Rusby, Bull. N. Y. Bot. Gard. iv. 380 (1907). An examination of a 
cotype of this species (Bang, no. 2114) in the Gray Herbarium shows 
not only that it has the general habit and foliage as in T’richogonia, 
but possesses the plumose pappus characteristic of that genus, to which 
accordingly it should be referred. 
EUPATORIUM BETONICIFOLIUM Mill, var, integrifolium (Gray), comb. 
nov. FE. Hartwegi Benth. Pl. Hartw. 19 (1839). Coelestinia Hartwegi 
(Benth.) Walp. Rep. ii. 545 (1843). Conocliniwm betonicum DO., var. ! 
integrifolium Gray, Pl. Wright. i. 88 (1852). Hupatorium betonicum 
(DC.) Hemsl., var. swbintegrum Gray, Syn. Fl. i. pt. 2, 102 (1884). 
Conoclinium integrifolium (Gray) Small, Fl. 8. E. U. 8. 1170, 1338 
— Eupatorium betonicum, var. intregrifolium (Gray) Small, 
ce. 
EUPATORIUM COELESTINUM L., var. SALINUM Griseb. Cat. Pl. Cub. 146 
(1866). This plant (Wright's no, 2811 from Cuba) though a marked 
form is described somewhat misleadingly thus: “ forma foliis acute 
dentatis.” The teeth of the leaves are in fact by no means acute, 
being in most instances actually rounded at the tip; but whiat pa 
nishes the really striking difference between this form and the 5 at 
E. coelestinum is the fact that the leaves are considerably more deep! y 
and somewhat doubly toothed. The blades also are of a more deltot 
outline.
