D. Leschenaultianum. — A native 

 of the mountains of S. India and 

 Ceylon, grows 1 to 2 ft. high, and 

 produces white bell-shaped flowers in

 treatment. 



D. Menziesi. — A native of California, 

 ] to 3 ft. high, with greenish flowers 

 and oval lance-shaped leaves rounded

D. pnllum (Jj. fulvum ; TJvularia 

 ddnenfifi). — A singular - looking 

 Chinese and Indian plant about H 

 ft. high, with angular zigzag stems, 

 ovate lance-shaped pointed leaves, 

 and brownish flowers in September

 There is a smaller yellow- flowered

DOLICHOS (doliko$, long ; referring 

 to the long shoots). Nat. Ord. 

 Legummosae. — This genus contains 

 over twenty species of more or less 

 climbing plants, with three foliolate 

 leaves, and clusters of pea-like 

 flowers. 



D. simpUcifoiius. — This species 

 from Tropical Africa differs from 

 most of its tribe in having a woody, 

 tuberous root -stock, from which arise 

 annually herbaceous, erect stems 

 about 1 ft. long, bearing simple lance- 

 shaped leaves about 6 ins. long, in 

 the axils of which clusters of pink 

 pea-shaped flowers are produced 

 (Bot. }farj. t. 7316). 



This species is of botanical interest. 

 It should be grown in sandy loam in 

 a warm greenhouse or stove. The 

 same may be said of another species, 

 pseudoiMidojrrhizxa, which has a large 



tuberous root-stock, climbing stems, 

 three-foliolate leaves, and violet-blue 

 flowers in racemes 6 to 18 ins. long.

 tuber-like stems produced at the
