Wooton: THE LARKSPURS OF NEw Mexico 35 
Defiance, New Mexico, June 18, 1883, Marsh (U. S. Nat. 
Herb., 70. 7997).

A small scrap of a Delphinium collected by W. B. Pease in 
New Mexico (doc. ?) in 1878 (U. S. Nat. Herb., sheet vo. 725,937) 
belongs in this group, but the material is too scanty for identifica- 
tion with the means at my command. 
4. Delphinium amplibracteatum sp. nov. 
An erect tall plant, appressed-pubescent throughout; leaves 
palmately deeply 5-parted into narrowly oblong or cuneate lobes, 
these again lobed and toothed into narrow oblong divergent 
divisions or teeth, the ultimate divisions from 3-5 mm. broad, 
abruptly rounded and tipped with a small callosity, about equally 
pubescent on both surfaces with short, curled white hairs ; inflo- 
rescence a strict raceme about 4o cm. long, the lower pedicels 5 
cm. long, the upper ones bearing open flowers but 1 cm. long; 
bracts extremely variable, those of the inflorescence below |leaf- 
like, twice 3-lobed, making the flower appear axillary, those of 
the middle of the raceme oblanceolate, few-toothed, 2-3 cm. long, 
attached to the middle of the pedicels; those toward the top of 
the raceme smaller and entire, but never linear and acuminate like 
the bracts of its nearest allies; floral bracts showing the same 
variation, the lowermost being foliaceous and toothed, only the 
upper ones being acuminate; flowers bright blue, about 2 cm. 
long, all parts which are outside in the bud appressed-pubescent, 
spur slightly longer than the sepals, rather slender, straight, hori- 
zontal or ascending ; sepals elliptic, obtuse, the uppermost slightly 
narrower, each with a pronounced saccate callus at the apex ; 
upper petals blue above, greenish white below; lower petals 
broadly oblong, irregularly 2~3-toothed, not deeply bifid; ovary 
appressed-pubescent, not viscid ; mature fruit not seen. 
Type collected by E. O. Wooton at the N Bar Ranch in the 
Mogollon Mountains, Aug. 2, 1900, at an altitude of about 2100 
m. in open pine forest. 
This description rests upon a single specimen and but for the 
peculiar bracts I should not name it. I have waited in vain for 
several years for more material, but the region is so difficult to 
get to that no collector has been there since. The material is
