BIGI70ITIACEAE 



Thec oma stans, Wild Trunpet Plant, is confined in our region 

 to western Texas and southern New Mexico and Arizona. It is a very 

 handsome low shrub with pinnate leaves and large brilliant yellow 

 trunpet- shaped flowers. Years ago Mr. M. E. Mus grave of the Soil 

 Conservation Service introduced this plant into the commerce of the 

 southwest. For many decades, probably hundreds of years, it has 

 been used by the inhabitants of Mexico as an ornamental. At pre- 

 sent Mr. M. E. Musgrave has plants growing in his yard at Albuquerque, 

 Hew Mexico. Frequently, even in southern Arizona, this plant freezes 

 to the ground but it readily sprouts from the roots. 



ACAHTBACEAE 



* Anis acanthus thurberi, Desert Honeysuckle, is confined to 

 southern New Mexico, southern Arizona and Mexico. It is a shrub 

 with opposite, rather broad lanceolate leaves and white papery 

 bark. It is browsed extensively when more palatable forage becomes 

 scarce. It is a fair erosion control plant along dry washes. It 

 is ideal for nursery production from cuttings but seed production 

 is small because of a tiny fly which infests the seed pods, des- 

 troying the seeds. Cuttings and nursery stock used for range plant- 

 ing is severely injured by jack rabbits. Although nursery stock has 

 been raised at Albuquerque it is nob yet known that this species 

 will withstand the climate of the Upper Rio Grande or of the north- 

 ern portion of Hew Mexico generally. 



There are several other Acanthaccous plants which arc interest- 

 ing as forage or erosion control plants. These have not yet been tried 

 en the nursery or on the range but they are worthy of mention and some 

 of an early trial. 



Belopcrone calif om ica is a tender shrub confined with us to 

 the warmer portions of southern Arizona and southern California. 

 It has drab, hairy opposite thick leaves and red flowers. It is 

 a good erosion control plant in some of the extremely hot south- 

 western deserts as it protects the banks of dry washes but it is 

 hardly suitable in any regions on which we are at present conduct- 

 ing control work. 



Tetramerium hispidum is a low herbaceous perennial which is 

 abundant in rocky sites at lower altitudes in our southwestern 

 ranges and is found not infrequently in me s quite regions where it 

 is difficult for stock to get. It is highly palatable and will not 

 withstand heavy grazing. Plants are easy to establish in the nursery 

 either from roots collected in the field or from seed. This species, 

 however, is hardly significant as an erosion control agent.
