mesa above the Abbott Ranch, Rito de los Frijoles, northwest of Santa Fe, 

 New Mexico, in August, 1912, by Mr. Frank Springer (No. 4). 



This proposed new species is related to N. multicaulis and N. multi- 

 flora, but in most of its dimensions it is smaller than either. Nuttallia 

 multiflora, particularly, has much larger flowers, as well as broad and 

 more dissected leaves. The seeds, too, are unlike those of the two species 

 mentioned. 



The specimens were forwarded by Prof. T. 1). A. Cockerell. At his 

 request, the species has been named in honor of its collector, Mr. Frank 

 Springer, who is well known for his contributions to the science of pale- 

 ontology. 



Amelanchier australis Standley sp. nov. 



Slender shrub 2 meters high or less with ascending branches; older 

 twigs glabrous, brown or grayish brown, the younger ones tomentose or 

 villous with white hairs; buds ovoid, more or less villous; leaf blades 

 thick and coriaceous, ovate-oblong or rounded-oblong, 20 to 32 mm. 

 long, 14 to 25 mm. broad, rounded to nearly truncate at the apex or 

 sometimes acutish, broadly rounded or truncate at the base, pale dull 

 green, villous on the upper surface with mostly appressed hairs, more 

 densely villous or tomentose beneath, coarsely crenate-serrate above the 

 middle, the teeth abruptly short-pointed; petioles slender, 5 to 7 mm. 

 long, villous or tomentose; stipules 6 to 10 mm. long, subulate, reddish 

 brown, villous, soon deciduous; racemes terminal, slender, sometimes 

 somewhat paniculate, each with 6 to 15 flowers; pedicels slender, erect, 

 5 to 15 mm. long, densely villous with mostly appressed hairs; hypan- 

 thium in anthesis campanulate, bright green, sparingly villous; calyx 

 lobes bright green, lanceolate to narrowly elliptic or linear-lanceolate, 4 

 to 5 mm. long, acute, villous on both surfaces, after anthesis reflexed or 

 spreading and accrescent, equaling or exceeding the fruit; petals narrowly 

 oblong or elliptic-oblong, narrowed at the base, obtuse, 5 to 6 mm. long; 

 mature fruit not seen, the best developed immature ones spherical, 

 slightly villous, 5 to 6 mm. in diameter. 



Type in the U. S. National Herbarium, No. 661,083, collected at Ropes 

 Spring in the San Andreas Mountains, Dona Ana County, New Mexico, 

 September 23, 1912, by E. O. Wooton. 



This is as closely related to Amelanchier oreophila A. Nels. as to any New 

 Mexican species. That, however, so far as now known, reaches only the 

 mountains of the northern part of the State, occurring in the Transition 

 Zone. The locality for A. australis is in the Upper Sonoran Zone. 

 Amelanchier oreophila differs from this shrub of southern New Mexico 

 in its thinner, bright green leaves, fewer flowers, and less abundant 

 pubescence. The new species here described is best distinguished by 

 its bright green, foliaceous calyx lobes, which are unlike those of any other 

 North American species.
