ROSACEAE 



Plants of this character, however, handled with extreme care give 

 practically no results in the nursery or the field. Seeds, however, 

 germinate readily and one year old seedlings are not difficult to 

 transplant. Direct planting of the Apache Plume in the field should 

 give good results if proper methods can be developed. 



V auque linia californica or Arizona Rosewood, is an evergreen 

 tree with thick, grayish, linear crenate -margined leaves and large 

 clusters of white rosaceous flowers. It is frequently a tree up to 

 30 feet high with a trunk 1 to l-g- feet in diameter. More often, 

 however, it is a low, much branched shrub. The v/ood is very beauti- 

 ful and as hard as adamant and very heavy. Apparently it has never 

 been used for commercial purposes owing to the inaccessibility of 

 the trees, their extreme slow growth and small size. It is confined 

 to the southwestern ranges from southwe stern New Mexico to southern 

 California and south into Mexico. Owing to its extreme slow growth 

 it is unsuited to erosion control work. Recently this was discovered 

 to be the host of one of the O-ymnocporangias which attacks Junipers. 



Gor bus, soop ulina , the Mountain Ash, has a very wide range in 

 the west but grows at relatively high altitudes. It is frequently 

 used, as a yard and street ornamental because of its beautiful pin- 

 nate foliage and large clusters of flowers and fruits. It is one 

 of the ornamentals which is frequently sold in commercial nurseries. 

 It has no place in a revegetation program except possibly as an 

 ornamental along highways at high altitudes. One of the Gyrnnos- 

 porangia attacking Junipers lives on this as its alternate host. 



P eraph yllum ramosissimum, Colorado Bitter Crab, is a tall, 

 widely spreading shrub, very common in southern Colorado and ex- 

 tending into northern How Mexico. It has narrow leaves and blos- 

 soms and fruits which closely resemble those of the apple. It is f 

 an excellent soil binder on slopes just below the yellow pine reg- 

 ion and extending into the pinons. Its use in the revegetation 

 program cannot be recommended, however, where junipers are likely 

 to be planted or where they arc already present. It is extremely 

 susceptible to at least two of the Gymno sporangia s . 



MIM03ACEAE 



Calliandra eri ophylla, Fairy Duster, stands paramount among 

 shrubs on our extreme southwest ranges both as an erosion control 

 plant and as forage. It ranges throughout western Texas, southern 

 Arizona, i-Jcw Mexico and almost throughout Mexico. A good grass 

 range well dotted with this plant can be considered the ideal stock 

 range. This shrub can be oaten down close to the ground and thorou- 

 ghly trampled and yet survive. Seed germinate readily and plant
