326 APOCYNACEAE. 
Nerium. Oleander. 
(Family Apocynaceae). 
Shrubs or small trees with 
milky sap: evergreen. Twigs 
moderate, more or less 3-sided: 
pith moderate, irregular, spongy. 
Buds solitary, sessile, small, round- 
ed, with 2 or 3 exposed scales. 
Leaf-scars in whorls of 3 or op- 
posite, broadly triangular, slight- 
ly notched, little raised, the axils 
tomentulose and fringed: bundle- 
trace 1, rounded: stipule-scars 
lacking. Leaves lance-oblong, en- 
tire, firm, slightly revolute, the 
lower surface with minute pubes- 
cent pits in which the stomata 
are grouped. 
Notwithstanding its attractive 
flowers, the oleander, which has 
made itself at home in the South- 
west, is regarded with disfavor as 
being poisonous. This aspect of 
the plant is presented by Wilson in Bulletin 59 of the Ari- 
zona Agricultural Experiment Station. 
Branches green and puberulent, becoming glabrous. 
N. Oleander.
