The original plant of Cavanilles, judging from his description 
and figure, was referable to the var. vulgaris above named. Hol- 
way 3054, from Mexico City, and Berlandier, without number or 
habitat, are more or less intermediate between var. hypomalaca 
and var. adenotricha. 
Schizoptera lyrata Klatt! Ann. Naturh. Hofmus. Wien ix. 360 
(1894). The type collection of this species, Schmitz 609, now in 
the Gray Herbarium, is identical with Duaes1a mexicana Gray, 
Proc. Am. Acad. xvii. 216 (1882), with which it was identified some 
_ years ago by Drs. Robinson and Greenman, although no pub-

which S. trichotoma Turez. is a synonym. 
GrypocarpHa Greenm. Trees & Shrubs i. 145, t. 73 (1903). — 
Sanvitaliopsis Sch. Bip. ex Benth. & Hook. Gen. Pl. ii. 357 (1873), 
as syn. (Zinnia); O. Hoffm. Nat. Pflanzenfam. iv. pt. 5,225 (1890), 
as syn.; Greenm. Proc. Am. Acad. xli. 260 (1905). — According 
to the International Rules of Nomenclature, the name to be used 
for this genus is the one given above. Sanvitaliopsis, a manuscript: 
name used by Schultz in the Liebmann Compositae (no. 552), WaS 
never published until given by Bentham & Hooker as a synonym , 
2 —— and again used in synonymy by Klatt and later byO- 
offmann, always as a synonym of Zinnia. Such publication 
does not validate a genus, and the name must give way to that of 
Grypocarpha, properly published by Greenman in 1903. The adop-
