ANACAEDIACEAE 215 



Daphniphyllum macropodum Miquel. 



A glabrous shrub or small tree, 8-10 m. tall. Branchlets red. Leaves 

 oblong, about 22 cm. long and 5 cm. wide, bluish on the under surface; 

 petiole red, 2.5^5 cm. long. Fruit black, 12 mm. long. 



Central China and Japan. 



ANACARDIACEAE 



Trees or shrubs with resinous or milky sap. Leaves alternate, 

 simple, trifoliate or pinnate, without stipules. Flowers regular, perfect 

 or unisexual, sometimes polygamous, small and numerous. Calyx 5 

 cleft; petals 3-5, alternate with the sepals or absent ; stamens as many 

 as or twice as many as the petals, rarely more, inserted with the petals 

 at the base of the disk. Ovary 1, rarely 2-6 celled ; ovules 1 in each cell. 

 Fruit a drupe or nut, rarely dehiscent. Seeds exalbuminous. 



About 50 genera and 400 species, mostly in the tropics of both 

 hemispheres. Ehus, the largest genus, reaches farthest north. Mango, 

 Oashew, Anacardium and Pistacia are important tropical or subtropical 

 genera. 



KEY TO GENERA 



I. Ovary 1 celled; fruits small; compressed, composed of 1 seeded 

 drupe. 



A. Flowers apetalous Pistacia. 



B. Flowers with petals Rhus. 



II. Ovary 2-5 celled, fruit a large ovoid diupe, the stone several 

 celled Spondias. 



SPONDIAS 



Trees. Leaves deciduous, alternate, odd pinnate, witli opposite, 

 stalked leaflets. Flowers polygamous, in racemes or panicles; calyx 4-5, 

 small, deciduous; petals 4 or 5; stamens 8-10; styles 3-5; ovary sessile, 

 3-5 celled; ovules solitary in each cell. Fruit a drupe with fleshy exocarp 

 and a hard, bony endocarp, 1-5 celled. 



j^bout 12 species of subtropical plants in the West Indies, tropical 

 America, India and China. The branches root readily when cut off'and 

 inserted in the ground; for this rrason, Spondias is especially useful as 

 windbreaks and hedges and for holding sandy banks.
