PLANTZ FENDLERIANZ. 55 
steep sides of the mountains, between rocks, eleven miles above Santa Fé; June, July. 
—A very handsome species, well distinguished by its remarkably small leaves. The 
specimens bear a profusion of flowers, which are for the most part solitary at the apex of 
the branchlets, and are large in proportion to the foliage, the petals being nearly equal in 
size to the leaves themselves. Their margins are somewhat erose. 
267. Jamesia Americana, Torr. § Gray! Fl. 1. p. 593. Banks of Santa Fé 
Creek, near the water, where the stream is walled in on both sides by high rocks ; June. 
— The genus was founded upon an extremely imperfect specimen, gathered by Dr. 
James in Long’s expedition to the Rocky Mountains. The fine specimens brought by 
Fendler now afford the opportunity of completing, and correcting in some points, the 
generic character ; which is accordingly appended.*

foliis oppositis, exstipulatis, petiolatis, ovatis vel oblongis, penninerviis, grosse serratis, membranaceis, deciduis, 
supra pubescentibus viridibus, subtus cum ramulis calycibusque canescenti-pilosis ; floribus cymosis, majuscu- 
lis, albis ; petalis intus puberulis. 
The foliage and flowers are somewhat like those of Pyrus Aria in aspect. — To the vicinity of this genus 
I should haye referred the curious Pterostemon Mexicanus, Schauer, in Linnea, 20. p. 736, which is also in 
Coulter’s- Mexican collection, no. 85, from Zimapan (but without fruit), except that Schauer describes the 
seeds as destitute of albumen, and notices minute stipules. He refers the genus to Pomacez, and considers it 
as an intermediate link with Myrtacez. I notice that the petals are convolute in zstivation : but so they are, 
likewise, in Gillenia.
