﻿New and interesting Plants from Western North America.— IV. 



By A. A. Heller. 



FENDLERELLA gen. nov. 



[Fendlera § Fendlerella Greene, Bull. Torr. Bot. Club, 8 : 



26. 1881.] 



Low, cymosely much branched shrubs, with small, opposite, 

 or subverticillate leaves, narrowed at the base, and sparingly ap- 

 pressed pubescent : the slender branches terminated by compound 

 cymes, which bear small, white flowers, these five-merous : calyx 

 cylindrical turbinate, pubescent, its lobes oblong : petals oblong, 

 unguiculate : capsule oblong, affixed to the calyx-tube for half its 

 length : cells one-seeded. 



Fendlerella Utahensis (Wats.) 





Whipplea Utahcnsis Wats. Amer. Naturalist 7 : 300. 1873. 

 Fendlera Utahensis Greene, Bull. Torr. Bot. Club, 8 : 26. 

 1881. 



Originally collected by Mrs. E. P. Thompson, at Kanab, in 

 Southern Utah, " on dry rocky cliffs ; July, August." That this 

 plant is not a Whipplea is evident, neither does it agree much bet- 

 ter with the genus Fendlera, with its large usually solitary flowers, 

 tetramerous, and its ovoid capsule, which is attached to the calyx- 

 tube only at the base. At first sight, dried specimens suggest 

 Ceanothus Fendleri. Good specimens were collected by Dr. D. T. 

 MacDougal in the Grand Canon of the Colorado, Arizona, June 

 26, 1898, no. 158. 



Inadvertently the wrong authority was cited in my treatment of 

 a species of Opidastcr on page 581 of this volume. The citation 

 should read as follows : 



Opulaster pauciflorus (T. & G.) 



Spiraea opulifolia, y pauciflora T. & G. Fl. N. A. 1:414- J 8 4° 

 Spiraea pauciflora Nutt. MSS.; T. & G. Fl. N. A. i: 4 J 4 



1840. 



Ncillia malvacca Greene, Pittonia, 2 : 30. 1889.
