gis, 2 mm. longis; staminodia membranacea; ovaria pubescen- 
tia, stylis rectis stamina superantibus; folliculi ignoti. 
Hab. In the Pinus ponderosa area, Buckskin Mountains, 
Northern Arizona. (Tidestrom, no. 2328, June 28, 1909.) 
There is another species, A. longissima Gray, which is 
still more remarkable on account of the length of the spurs. 
In this species we find the spur sometimes over 1 dm. in length 
and the relation of the length of the sepals to that of the 
spurs is sometimes 2.5:10. Of A. longissima, I have seen only 
two specimens, one collected by Dr. E. Palmer in the Caraco! 
Mountains, Coahuila, Mexico, and the other by Dr. V. Havard, 
in Los Chisos Mountains, Texas, near the Mexican boundary. 
A. longissima differs from our plant by its greater height; 
by its much larger leaves, with petioles sometimes 3 dm. or 
longer; and by its linear-oblong sepals. 
ugust 22, 1908, while riding over the Wasatch 
Plateau, near the eminence called Wasatch Peak, I met with 
another Aquilegia which does not appear to be related to any 
of the above eim os species. It grew at an altitude of 
3150 m., in the sand and among the gravel and loose rock 
which is so haracterite of certain slopes in the Wasatch 
Mountains. The plant is apparently sub-alpine and very rare, 
"aen I have not seen it in other eee localities, —not even 
e Big Horse Shoe Summit (3600 m. alt.), some twenty- 
^ miles occae nor on Mount Teri (3300 m.). The 
following is the diagnosis of our form 
Aquilegia scopulorum nov. sp. 
Herba perennis, glabra v. supra pubescens, 1-2 dm. alta,

This plant differs feo Kite coerulea var. calcarea 
Jones, by its cauline leaves, which in the latter form 
he lobes oval and entire. As to the leaf-form, f. 
calcarea is vict closely related to A. scopulorum than t 
A. coerulea. In our plant the petioles as well as the leat- 
blades and lower part of the stems are glabrous and glaucous. 
Mr. Jones, however, describes his form as having “petioles
