TREES AND SHRUBS 135 



native on the mesas and plains at the southern end of the 

 State. It would also probably respond to cultivation. Lycium 

 pallidum is a slightly larger species of shrub, sometimes 6 or 

 7 feet high, with purplish-brown thorny stems and medium 

 sized pale green leaves. It flowers are funnel form, dull green, 

 and about an inch long. The fruit is as large as a currant 

 and when ripe is dark red. It occurs on the drier slopes of 

 the mountains in the southern part of the State. 



Of the family Bignoniaceae there are two shrubby rep- 

 resentatives probably occurring in New Mexico. The Desert 

 Willow Jano (Chilopsis linearis) is one of the most satis- 

 factory of native shrubs for purposes of cultivation in dry sit- 

 uations. It is thoroughly at home in the arroyos and foothills 

 of the mountains at the lower elevations in our State, and is- 

 easily transplanted to the gardens. Under favorable condi- 

 tions of moisture it not infrequently reaches the size of a 

 small tree, while in most situations it is a shrub 5 to 15 feet 

 high. It may be pruned to the tree form or allowed to branch 

 at the base. Its long willow-like leaves give it its common 

 name. It is a profuse bloomer, having large purplish or whit- 

 ish flowers, somewhat after the type of catalpa blossoms. 



Stanolobium stans is another shrub that occurs commonly 

 in the mountains about El Paso, and probably gets into south- 

 ern New Mexico, though as yet it has not been collected with- 

 in our boundaries. This shrub is 3 to 5 feet high, with slender,, 

 graceful stems and large compound leaves, the leaflets of 

 which are an inch or two long and one-fourth as broad, dark 

 green above, paler beneath. It bears large yellow flowers in 

 conspicuous terminal clusters, and occurs in the driest of sit- 

 uations on the sides of the mountains. It should respond to^ 

 cultivation very readily, and would be well worth the care- 

 necessary to grow it. 



The Acanthus Family (Acanthaceae) has 2 shrubby rep- 

 resentatives in New Mexico. The first, Carlowrightia lineari- 

 folia, is a green stemmed branching shrub 3 or 4 feet high,.
