﻿Wooton : New Plants from New Mexico 457 



Collected also by Schott H between the Colorado and Santa 



Cruz River, Sonora," some time in the early fifties. Pringle's 



plants collected in Arizona on mesas and in valleys in flower, Apr. 



23, 188 1, and in fruit, August 3, 1884, belong here as well as the 



specimen collected by Dr. Wilcox at Fort Huachuca, Ariz., May, 

 1892. 



The plant is of course closely related to Prosopis glandulosa 



Torr, but is easily distinguished from that species by its velvety 



pubescence on the leaves, fruit and all young parts and by the 



leaves with frequently two pairs of pinnae and small crowded leaf- 

 lets. 



Parryella rotuxdata. 



Low shrub, 6 dm. high or more, branching at the ground and 

 spreading, young parts canescent, with appressed rather coarse 

 white hairs, numerous sessile brown glands on all parts : leaves 

 alternate, narrow, 10-12 cm. long, 7-10 mm. wide ; leaflets about 

 25 pairs, broadly elliptical to rotund, obtuse or retuse, 1—6 mm. 

 in longest diameter, the largest leaflets near the middle of the 

 rachis, those at the tip exceedingly small ; proper petiole short, 

 only 3-5 mm long; stipules about as long, narrowly lanceolate, 

 deciduous : flowers inconspicuous in short terminal almost sessile 

 crowded spikes, 1-2 cm. long, generally rather closely resembling 

 the flowers of the other known species : bracts linear, two-thirds as 

 long as calyx ; calyx-tube angular, turbinate, very canescent and 

 glandular, 2-3 mm. long ; limb 5 -parted, segments triangular, acute, 

 densely hirsutulose within: corolla wanting: stamens 10, free, 

 exserted, of unequal length ; anthers similar : ovary elliptical, two- 

 °vuled, and with the 4-5 mm. long style sparingly hirsute : fruit 

 unknown. 



Collected at a point about five miles north oi Winslow, Ariz., 

 J u ne 29, 1892, in reddish soil. 



It is easily separated from the only other known species of the 

 genus by its rounded leaflets and its very glandular calyx. The 

 exact size of the shrub will probably need correction, since I only 

 saw one poorly developed individual. 



Phacelia intermedia. 



Krect, branching, viscid, glandular and slightly hispidulous an- 



^ay T ~^ ^ m ' kigh (generally about 1.5 to 2 dm.) : stems terete, 

 dish tinged, quite glandular with a fine puberulence next the
