fiber of the leave? of this plant is used extensively for basketry* 

 Since this is more rapid growing and more easily transplanted than 

 some of the Yuccas it night be well to try it for erosion control 

 plantings. 



♦Yucca harrimaniae, Harriman Yucca, is a low acaulescent 

 form found naturally in southern Utah and southern Colorado. It 

 forms dense colonies and may be suited for erosion control work. 

 It grows in the heavy slippery soils with considerable alkali as 

 well as in more rocky sites. It is extremely drought resistant 

 and my be found suitable for erosion control work in certain sites. 



♦Yucca mohaven s i s , Mohave Yucca, is confined to the extreme 

 desert in northwestern Arizona and adjacent Nevada and California. 

 It extends southward into the desert of Lower California. Trunks 

 are three to fifteen feet high and grow cither singly or in small 

 clumps. It is doubtful if this plant has any place in our erosion 

 control program. Seedlings in the nursery at Tucson while appar- 

 ently healthy, are extremely slow growing. The one feature about 

 this plant is that the fruits when ripe arc very juicy and have a 

 fine flavor. If it were not for the work of the pronuba moth the 

 fruits might readily become a table delicacy. 



"Yu cca schcttii, Schctt's Yucca, is confined in our territory 

 to extreme southwestern Hew Mexico and southern Arizona. In 

 Santa Cruz County its apparent optimum rang;;, it grows to be ten 

 foot high or more and frequently forms caespitosc clumps a rod 

 or so square. It has enormous clusters of large flowers which are 

 greedily eaten by stock when they can reach them. The fruits are 

 large and both fruits and flowers arc doubtless used for food by 

 the Indians, The flowers should be tried as salad by nore adven- 

 turous wives of Soil Conservation Service. 



Vo rat ru n spec io sum, False Hellebore, is widely known in the 

 Rocky Mountains as Skunk Cabbage. This, however, is more properly 

 applied to a very different plant of the northern and northwestern 

 swamps, Ly sic hit on kajnts chat ens o. The Vcratrum grows at high 

 altitudes in wet places, forming dense stands. The plants bear 

 large, dark green leaves which at times are greedily eaten by 

 sheep, frequently with serious results as the plant is one of the 

 definitely poisonous herbs, heedless to stay, this plant is not 

 recommended for erosion control work.
