SAPOTACEAE. 285 



Chrysophyllum Cainito L., Star-Apple, tropical American, occasionally 

 planted, is a large tree with oblong or oval, petioled, pointed leaves 2'-6' long, 

 green above, yellow-brown and densely pubescent beneath; the small purplish 

 or whitish flowers are in sessile axillary clusters on slender pedicels about 5" 

 Jong, the corolla deeply 5-7-lobed, the purplish globose fruit 1^-4' in diameter, 

 8-10-celled, several-seeded. 



Sapota achras Mill., Sapodilla, West Indian, also occasionally planted, is 

 a large tree with oblong-lanceolate petioled glabrous coriaceous leaves, green 

 on both sides, 3'-5' long, the whitish flowers solitary in the axils, on rather 

 stout peduncles as long as the pedicels or shorter, the 5-6-lobed corolla about 

 as long as the pubescent sepals; the well-known fruit is a globular brown, 

 rough-skinned berry SV in diameter or less, usually containing several large 

 black shining seeds, 



Sideroxylon foetidissimum Jacq., Masticbully, West Indian, a large 

 tree, Avith oblong or ovate-oblong, evergreen rather thin, slender-petioled 

 leaves 8' long or less, the small yellowish pedicelled flowers in lateral or 

 axillary clusters, the nearly rotate corolla 5-parted, the oval drupe nearly 

 1' long, containing a single large seed, the pulp thin, grew in 1913 in a Paget 

 garden, the only tree of this species known to me in Bermuda. [S. masticho- 

 dendron Jacq.] 



Calocarpum mammosum (L.) Pierre, Mammee-Sapota, of tropical 

 America, recorded by Jones in 1873 as ''Mammee Apple," is a large tree 

 with obovate leaves 6'-9' long, greenish-white flowers about 6" wide, short- 

 pedicelled on the twigs, the rough oblong fruit 5'^6' long, usually containing 

 a single large seed. [Achras mammosa L.] 



A tree of a species of Lucuma, about 25° high, was observed at Bellevue 

 in 1913 ; it is probably L. multiflora A. DC, West Indian, but its fruit has 

 not been obtained. The oblanceolate to elliptic pointed short-petioled leaves 

 are 3'-5' long, the axillary, short-peduncled flowers have a white fugacious 

 tubular corolla about 3" long. 



Family 2. EBENACEAE Vent. 



Ebony Family. 



Trees or shrubs with very hard wood, entire estipulate leaves, and dioe- 

 cious polygamous or rarely perfect regular flowers, solitary or cymose in 

 the axils. Calyx inferior, 3-7-lobed, commonly accrescent and persistent. 

 Corolla gamopetalous, deciduous, 3-7-lobed, the lobes usually convolute in 

 the bud. Stamens 2-3 times as many as the lobes of the corolla in the 

 sterile flowers, and inserted on its tube, usually some imperfect ones in the 

 pistillate flowers; anthers introrse, erect. Disk none. Ovary superior, 

 several-celled ; in the staminate flowers rudimentary or none ; ovules 1-3 in 

 each cavity, suspended; styles 2-S, distinct, or united below^; stigmas 

 terminal, sometimes 2-parted. Fruit a berry. Seeds oblong, the testa bony ; 

 endosperm copious, cartilaginous; embryo small; cotyledons large, folia- 

 ceous. About 6 genera and 275 species, mostly tropical. 



1. DIOSPYROS L. 



Flowers lateral, cymose, racemose or solitary, th-e pistillate commonly 

 solitary, the staminate usually clustered. Calyx 4-6-cleft. Corolla ureeolate 

 in our species, 4-6-lobed. Stamens 8-20 in the sterile flowers. Styles 2-6 

 in the pistillate flowers; ovary globose or ovoid, its cavities twice as many as 

 the styles. Berry large, pulpy, containing 4-12 flat hard seeds. [Greek, Zeus' 

 wheat.] About 160 species, abund^ant in Asia. Type species: Diospyros
