1. DELPHINIUM CAMPORUM Greene, Erythea 2: 183. 1894 
Type locality: “A plant of dry sandy plains along the 
eastern base of the whole Rocky Mountain range, apparently 
from British America to Mexico,” 
I have not seen type material of this species, but from what I 
find of other species of this region it seems doubtful to me that a 
species occurring on the plains of Wyoming would occur in south- 
ern New Mexico. In a paper discussing the members of the 
azureum group of the genus,* Dr. Rydberg has referred two New 
Mexican specimens to the species under discussion. These are 
Thurber’s zo, 297 from the Jornado del Muerto and Rusby’s xo. 
5 from Mangas Springs. Thurber’s specimenI have not seen, but 
Rusby’s matches the following specimens : 
Mangas Springs, New Mexico, May 24, 1903, Metcalfe 85. 
Flats near Nutt, New Mexico, May, 12, 1905, Metcalfe 1579- 
Las Cruces (probably Organ Mts.), June, 1898, Herrick 215. 
Organ Mts., New Mexico, May 26, 1905, Wooton. 
Besides these, I have also the type of D. Wootoni Rydb.,* 
which is from the Organ Mts., and it seems to me hardly separ- 
able from the above named specimens. The Jornado del Muerto 
(a wide open plain about 75 miles long) ends at the Organ Mts. 
and it is likely Thurber collected his plant not very far from these 
mountains. If Dr. Rydberg is incorrect in assigning his New 
Mexican specimens to D. camporum Greene, all this material be- 
comes J. IWVootont Rydb.; otherwise the latter name becomes a 
synonym. 
2. Delphinium confertiflorum sp. nov. 
Plant low, 20 to 30 cm. high, tufted, from a perennial root, 
finely appressed-pubescent throughout with short white hairs ; 
* Bull. Torrey Club 26: 583 and 587. 1899.
