with very small leaves and inconspicuous pale blue flowers, 

 that grows upon the mesas at the southern end of the State. 

 It is of little or no economical importance. The second, 

 (Anisocanthus thurberi) is a branching shrub 3 or 4 feet high 

 with numerous stems, upon which are borne the rather large 

 pinkish flowers in considerable abundance. This plant grows 

 in the foothills of the southwestern part of the State, and is 

 well worth cultivation as a decorative plant. 



Bouvardia ovata is a low shrub, generally not over 3 feet 

 high, the upper portions of the stems herbaceous and leaves 

 1 to 2 inches long. Its flowers are bright red and tubular, 

 borne in terminal clusters an inch or so in diameter. This plant 

 occurs only in the extreme southwestern corner of the State, 

 coming in from Mexico. Several species of the genus are in 

 cultivation, and this one would lv well worth trying. 



The Honeysuckle Family (Caprifoliaceae). This family 

 contains several important shrubs and trees. The Elder 

 (Sambucus) is represented in our State by 5 well marked 

 species, all of which are worth cultivating. The Mexican 

 Elder Tapiro (Sambucus mexicana) occurs only in the I 

 hills at the southern end of the State, where it has probably 

 been introduced. It is a low stunted tree, with round, dense 

 top which retains its Laves almost throughout the year and 

 produces large clusters of whitish blooms throughout the 



summer season. Its fruit rarelv matures.

In the mountains four other species occur as shrubs, but

 defined trunk. One species (Sambucus microbotrys) has red 

 berries, while the fruit of the others is black. 



The Snowberry (Sytnphorkarpus) displays 3 species, 

 all of which are low shrubs from 1 to 5 feet high. The flowers 

 are usually small, tubular, pink or white, and are succeeded 

 by white 2-seeded berries. They are graceful plants and 

 rather profuse bin mers. and while the flowers are small, thev
