incurved. The striking columnar dark seeds are almost per- 
fectly tetragonal, 4.5™" long, and 2™™ broad, with the concave 
ventral facets slightly papillate; the caruncle is large, stipitate, 
and shaped like a water-carrier’s neck yoke. 
EUPHORBIA JALISCENSIS Durangensis var. nov. 
This form differs from the species in its denser foliage 
and more ramose habit. Heterophyllous; lower leaves linear- 
lanceolate, 0.5 to 4 inches long, upper leaves spatulate to 
panduriform, dentate at the cuneate apex, I-2 inches long, ~ 
as broad above the constriction as below. Involucre smaller 
than in the species, the glands less stipitate, the appendages 
narrower and only 4—6-crenate-dentate, the seed blacker and 
smaller (3™" long, 1.8™" broad), and the caruncle simply 
peltate.

EuPHORBIA RADIANS Benth. Pl. Hartweg. 8. 
The involucres of this spe- 
cies, described by Boissier 
(DC. Prod. 15: 74) as subses- 
sile, are pediceled one-half the 
length of the tube; the invol-— 
ucral lobes are from 4—6-fim- 
briate, the four missing glands 
are replaced by similar 1-2- 
fimbriate false lobes. The 
seeds are ashen, ovate, glob- 
ular in section, 4.1™™ long, by 
2.5™" brpad, the ventral facets 
marked by a strong transverse 
ridge, the dorsal by two, and 
numerous irregular verruce, 
not “smooth ;” a smooth seed- 
ed species could hardly belong 
to POINSETTIA. 
In Dr. Palmer's 34 Durango, the strigose hairy leaves are
