ELAEAONACEAE 



at moderate altitudes. They are frequently cultivated for wind- 

 breaks, ornamentals and for their fruit which makes very good jelly. 



Shophordia rotundif ol ia , the Round-leafed Buffalo Berry, is 

 a rare shrub found along the San Juan River, in the Grand Canyon in 

 Arizona and in Zion National Park. Scouting vail doubtless give it 



a wider distribution. It is an interesting shrub of a prostrate 

 or nearly prostrate habit, #iich grows in dry sites below cliffs as 

 well as similar sites where there is a little seepage. Its habit 

 suggests its use for erosion control work. Up to the present we 

 have net grown it in the 2iurseries. 



A third Buffalo Berry, Shcpherdia canadensis, grows in the 

 high mountains. It has no significance for erosion control work 

 but is sometimes used as an ornamental. The fruits are bright red 

 and as bitter as quinine. 



ONAGRACEAE 



The Evening Primrose family contains many showy annuals and 

 perennials, some of which are fair forage. The low creeping type 

 may even have som.e value for erosion contrcl. Host of the important 

 ones can be classified in the large composite genus, Oenothera, 

 which contains both the large white-f lowered forms and those with 

 small or large yellow flower::. All of these can be recognized by 

 their four petals and inferior ovary. Zauschne ria, californi ca 

 goes in this family but has a strikingly different flower. It is 

 red and somewhat irregular. The leaves are clamy. The plant has 

 a rhizomatous root system and is an excellent soil binder in draws 

 and in the mountains at about 4,000 feet elevation. This plant has 

 a wido distribution in the southwest. 



ARALIACEAE 



Aralia humilis is a very uncommon shrub occurring in the 

 United States only in southern Arizona. It has large bipinnate 

 leaves and umbels of flowers ana black fruits. It occurs only in 

 rocky canyons and en steep rugged north-facing slopes. It is a 

 tender shrub of no erosion control value but one vhich may prove to 

 be of value for an ornamental and for medicine. 



CQRI'TACSAE 



Garr y a spp . These tall shrubs are sometimes called Coffee 

 Berries because of the peculiar odor of the plants. They have 

 rather large, ovate to oblong, thick hard grayish leaves. There 

 arc three species in the southwest which quite closely resemble 

 each ether, the chief noticeable variation being in the pubescence 

 or hairiness of the berries. Those occur in spikes and are black
