﻿PLANTS FENDLERIAN.E. 55 



steep sides of the mountains, between rocks, eleven miles above Santa Fe ; 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.

 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.*

The foliage and flowers are somewhat like those of Pyrus Aria in aspect. — To the vicinity of this genus 

 I should have referred the curious Pterostemon Mexicanus, Schauer, in Linncsa, 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 Pomacese, and considers it 

 as an intermediate link with Myrtaceae. I notice that the petals are convolute in aestivation : but so they are, 

 likewise, in Gillenia.
