266 BOTANICAL GAZETTE [OCTOBER 
tral convex, linea ventralis slight; surface marked with short and 
irregular interrupted rugae, not pitted. 
Type from Kansas, Fendler no. 789, co-types New Mexico, Santa Fé, 
fendler no. 797 and Dofia Ana, Wright no. 59 (omnia visa). The 
following specimens agree well with type: Colorado, Marcus E. Jones 
no. 786 (1878); Durango, Mexico, Dr. Edward Palmer no. 43 (1896), 
Bor. Gaz. 25:19, 1898 ; Chihuahua Mexico, C. G. Pringle no. 1076 (1886) 
and his Coahuila, Mexico, no. 80 (1885). 
Var. a. Texensis, var. nov.—Similar to the species in general habit, but 
less hairy and of looser growth, with longer internodes. Lobes of the 
involucre columnar, pseudolobe a deep sulcus with a long linear pseudo- 
gland at its fundus; appendages very narrow, entire, and generally pres- 
ent. Seeds bluish-ashen, strongly tetrangular, 1™™ long, .6"™" broad, 
the dorsal facets concave, the ventral plane, all marked by strong, 
sharp, transverse rugae, that show only a tendency to anastomosis and 
interruption. 
Texas, southern portion, altitude 1600-2000 ft., 4. A. Heller, nos.

EUPHORBIA COROLLATA L. 
In this species, the most showy of the eastern United States, there 
is almost unlimited form variation in the general appearance of the 
plants from different localities, among which those given below may 
be considered good varieties by strong and reproducing differences 
in their leaves and glandular appendages. Inall the forms and varieties 
the seeds maintain their full and distinctive characters ; they are white- 
cinereous, ovate-pyriform with a strong nipple-like tip, sub-globular in 
section, 2.5"" long, 2™™ broad, linea dorsalis a rounded evident keel, 
linea ventralis a dark evident groove, the surface marked with irregular, 
very shallow, pits. 
Sp. COROLLATA L., Ameen. Acad. 3:122.—Leaves sub-petiolate, 
spatulate oblong, glabrous, green both sides, 3 long, 2™ broad. 
Floral pedicels 4™™ long, strict and filiform; appendages oval, plane 
3-7"" long, 2.1™ broad. 
Var. a. GRANDIFLORA Boiss., DC. Prod. 157: 67.— Leaves strongly 
sessile, lanceolate to narrow-lanceolate, glabrous, green both sides, 
2.8™ long, 1.4™ broad, less veined than in the species. Floral pedicels 
8™ long, strict and filiform, appendages broadly ovate, spreading and 
drooping, 3.3™" long, 4™ broad.
