﻿28 PLANTS FENDLERIANjE. 



ZANTHOXYLACE^E. 



94, 95. Ptelea angustifolia, Benth. ! PL Hartw. no. 42. Steep and rocky 

 banks of the Rio del Norte : No. 95, in flower, May ; No. 94, in fruit. " Shrubs from 

 7 to 10 feet hi^h : leaves of an agreeable odor." — The foliage becomes smooth and 

 shinin°- above with age. The fruit (which is wanting in the Hartwegian specimens) is 

 much smaller and more emarginate than in P. trifoliata ; and, like that species, .it is fre- 

 quently tricarpellary. 



A NACARDIACE.E. 



f96. Rhus Copallina, Linn. Bottoms, along the Kansas River. 



97. R. glabra, Linn. var. ? R. la?vicaulis, Ton: in Bot. Ex. Exped. ined. Steep 

 mountain-sides, valley of Santa Fe Creek ; July. — This clearly belongs to the Oregon 

 species which Dr. Torrey distinguishes from R. glabra, on account of its short calyx, 

 " scarcely half the length of the petals, linear-oblong anthers," &c. But a specimen 

 from New York has nearly as short a calyx, while in others it is as long as the corolla. 

 Being sub-polygamous plants, I suspect that the difference may be attributed to sex. 



98. R. Toxicodendron, Linn.; Ton: fr Gray, El. 1. p. 218. Valley of Santa Fe 

 Creek, in the mountains ; June. 



l 99. R. (Lobadium) trilobata, Nutt. in Torr. 8f Gray, Fl. 1. p. 219. Rocky pre- 

 cipices, overhanging the Rio del Norte, in flower and fruit ; May. Also on the Mora 

 River, in ripe fruit ; August. Shrub 3 to 8 feet high : possesses a peculiarly disagreeable 

 odor. — Some (fruiting) specimens are nearly glabrous, as described by Nuttall : others 

 are softly cinereous-tomentose. The ripe fruit is scarlet, and sparsely hirsute. 



ZYGOPHYLLACE.E. 



" 100. Kallstrcemia maxima, Ton: 8f Gray, El. 1. p. 213. (Tribulus maximus, 

 Linn.) Plains and waste places, Rio del Norte and around Santa Fe ; May to Aug. — 

 The inappropriate specific name was derived from the Tribulus terrestris major, Jiore 

 maximo of Sloane ; but the flower is far smaller than in T. cistoides, L. The latter 

 (which grows on Key West, kc.) is a genuine Tribulus. 



ACE RACEME. 



^ 101. Acer tripartitum, Nutt. in Ton: 8f Gray, El. 1. p. 247. Shady places, near 

 the creek, in the mountains east of Santa Fe ; May, in flower ; June, in fruit. A 

 shrub 15 feet high, of slender growth. — A beautiful species, allied to A. glabrum,
