The family Sapotaceae, which consists of about 445 species distributed in 
more than 31 genera, occurs in the tropics of the whole world, but is absent in 
Europe and extra-tropical Asia. In the Hawaiian Islands two genera are rep- 
resented: Chrysophyllum with a single species, and Sideroxylon with four dis- 
tinet species and several varieties, all of which are peculiar to these Islands. The 
Sapotaceae are characterized mainly by their milky sap, and regular cyclic con- 
struction of their flowers. All Sapotaceae are woody plants with entire leaves, 
Save in a single exception.

ing. Cotyledons thin, foliaceous——Milky trees with alternate ovate or lanceolate leaves, 
without stipules. Flowers usually small, whitish or yellowish, shortly stipitate in axil-

The genus Chrysophyllum, with its 70 species, is mainly tropical and is most 
numerous in species in tropical America. 
In Hawaii the genus is represented by a single species, Ch. Polynesicum Hbd., 
which is peculiar to these Islands, and inhabits the dry regions on the leeward 
sides, but is by no means common.
