16 BOTANICAL GAZETTE [JANUARY — 
slight and ashen. Jn this and the related species, £. hyperictfolta, 
E. nutans, E. lasiocarpa,and E. Brazilensis, there exists a minute 
black caruncle that appears to have escaped the attention of the 
authors of the species. 
EuPHORBIA NUTANS Lag.? Gen. et. Sp. nov. 17. : 
In Dr. Palmer’s 226 Durango we find a form that answers 
exactly to Lagasca’s species, so far as his meager description 
gives the characters of his plant. In the absence of his type, I 
cannot do better than to accept, as a basis of differentiation 
between it and &. Pres/i, his ‘‘floribus axillaribus solitariis,” 
which cannot possibly mean any known form of the glomerate 
flowered E. Presiii. Lagasca says: ‘‘Caule patulo dichotomo 
villoso: ramis apice floriferis nutantibus: foliis ovato-oblongis 
subcordatis obsolete serratis: floribus axillaribus solitariis,’’ to 
each and every character of which Dr. Palmer’s plant agrees, 
except mayhap the ‘‘villoso,” a character never determinative 
or constant in any plant. Taking this form, therefore, to answer 
to £. nutans Lag.,l add the following to the original descrip- 
tion: Caule patulo dichotomo 
villoso at the extremities of 
s the branches only, ramis apice — 
floriferis, the upper angulate, 
the lower striate, the stems 
terete ; folits ovato-oblongis sub- 
cordatis obsolete serratis at the 
apex, 3-nerved ; stipules inter- 
petiolar, triangular, long fim- 
briate-ciliate ; floribus axillari- 
bus solitariis, involucres small, 
turbinate, long pediceled; 
lobes lanceolate, 3 to 4-irreg- 
ular-fimbriate, glands 4, small, ovate, appendages little more than 
a sarcous dorsal ridge upon the stipe of each gland, fifth gland 
replaced by a 2-fimbriate smaller involucral lobe; capsule gla- 
brous, carpels obtuse; seeds ashen-black, the transverse ruge 
more prominent than in Z. Presii, the ventral suture extending 
from the caruncle downward, 
and the dorsal angle sharper.
