462 Thirty-first Annual Report 



without injury, and thrives in both valley and mesa soils. It can 

 be used to advantage as an undershrub in planting. It grows 

 readily from cuttings or by layering and has been under observa- 

 tion for ten years. 



Solanum jasminoidcs is a clean, evergreen climber from Brazil. 

 It has smooth, glossy leaves and propagates readily by layering. 

 The flowers are white, very attractive, and borne in clusters, and 

 are produced in abundance from spring until late in the fall. It is 

 tolerant to our hot summer weather and has not been injured with 

 temperatures of 12 degrees Fahrenheit. 



Common Rosemary (Rosmarinus officinalis) is an evergreen shrub, 

 with a pleasing aroma and spreading branches that grow three to 

 five feet tall. The leaves are narrow and rather thick, with the 

 edges recurved, and the flowers are light blue and appear during the 

 winter and spring seasons. This is an excellent bee plant and can 

 be propagated readily from cuttings. It is a native of the Mediter- 

 ranean region, is drought resistant, and grows well under our 

 conditions. 



Golden bell (Forsythia suspensa) is an attractive shrub with 

 smooth, yellowish-brown, recurved stems. The leaves are smooth 

 and drop late in the fall. The plant is a native of China and pro- 

 duces a wealth of golden yellow flowers early in the spring before 

 the leaves appear. 



Algerita (Berhcris trifoUata) is an evergreen shrub with thick, 

 tough, bluish-green and more or less spiny leaves. The stems are 

 reddish-brown and the flowers are yellow and borne in the spring. 

 It is a native of western Texas and very resistant to southwestern 

 conditions. The plant resembles generally our native Fremont'-s 

 barberry, but is perhaps more ornamental. The fruits are edible. 



Common Jujube (Zizyphus sativa) is a small, deciduous, spiny 

 tree or large shrub from the Mediterranean region. It is of erect 

 growth and very attractive during the growing season with its 

 glossy foliage. The fruits are about the size and shape of an olive, 

 blackish when ripe, and produced in enormous quantity. Plants 

 have been under observation for 12 years and have endured with- 

 out injury the usual summer temperatures and winter temperatures 

 as low as six degrees Fahrenheit. On the University ground in 

 lime soil the growth was very unsatisfactory, but at the University 

 Farm with more or less alkali in the soil their growth has been 

 all that could be desired. These plants are regarded as entirely 

 hardy for growing under southern Arizona conditions and they 

 should prove a valuable secondary fruit for the home.
