Apocynaceae. 



Allamanda. 

 (Family Apocynaceae). 



Tender usually scrambling 

 shrubs with milky sap: ever- 

 green. Stems green or reddened, 

 obtusely somewhat angled below 

 the leaves, moderate: pith rather 

 large, roundish, spongy. Buds 

 rather small, solitary, sessile, 

 roundish, with 2 pairs of scales. 

 Leaf-scars variably opposite or in 

 whorls of 3 or 4 or 5, half-round 

 or half-elliptical, raised: bundle- 

 trace 1, indistinct: stipule-scars 

 lacking, but persistent outer 

 scales occupy the position of sti- 

 pules, which are considered to be 

 characteristically absent from the 

 family. Leaves simple, entire. 



Though the Tropical American 

 allamandas are known only as 

 conservatory plants in the North, 

 in one or other of the distinct 

 forms that are collectively named A. cathartica, their large 

 yellow flowers are familiar everywhere. In the extreme 

 South, they make effective and showy covering for trellises, 

 etc.
