CLUSIACEAE. 



petioled, ovate-elliptic, acuminate leaves 4'-6' long, and numerous small flowers 

 in terminal panicles, the five petals hairy, the fruit berry-like. H. B. Small 

 regarded the determination of this plant as doubtful. 



Family 4. CLUSIACEAE Lindl. 

 CLUSIA FAMILY.

 dioecious or polygamous flowers in cymes or solitary. Sepals 2-6, imbri- 

 cated. Corolla of 1-9 hypogynous petals. Stamens numerous in the stam- 

 inate flowers, in the pistillate flowers usually represented by starninodes; 

 filaments usually more or less united into a tube. Ovary 1 -several-celled ; 

 styles stout, or wanting in some genera ; ovules one, several or many, borne 

 on axile placentae. Fruit baccate, drupaceous or capsular. Endosperm 

 none. About 40 genera and some 500 species, natives of tropical regions. 



1. CALOPHYLLUM L. 



Trees with short-petioled, coriaceous, pinnately striate-veined leaves, and

 2-4; petals 1-4, or wanting. Stamens many, distinct, or their bases united; 

 filaments short; anthers ovate or oblong. Ovary 1-eelled; style long or short, 

 the stigma peltate; ovule 1, erect. Fruit a drupe. [Greek, beautiful-leaved.]

1. Calophyllum Calaba Jaeq. 



GALBA. SANTA MARIA. (Fig. 270.) 

 A tree, becoming at least 60 high, 

 often branched nearly to the base. 

 Leaves elliptic or oblong-elliptic, 3'- 

 6' long, glabrous, dark green, rounded 

 or slightly emarginate at the apex, 

 narrowed or obtuse at the base, shin- 

 ing, the midvein rather prominent, 

 the lateral veins very numerous and 

 close together ; racemes lateral or 

 axillary, few-flowered, much shorter 

 than the leaves; pedicels rather stout, 

 2"-5" long; flowers white, fragrant, 

 the few petals about twice as long as 

 the orbicular sepals, or petals want- 

 ing; staminate flowers with about 50 

 stamens; pistillate flower with a 

 short style, a globose ovary and 

 many starninodes; drupe nearly 1' in 

 diameter, the endocarp crustaceous. 



Hillsides, hedges, and planted along roads. Introduced from the West Indies 

 and naturalized. Flowers in late summer and autumn. 



Mammea americana L., MAMMEE APPLE, West Indian, is represented by 

 a few trees in gardens; a fine tree may be seen at Par-la-Ville. It has thick, 

 leathery, oblong-obovate leaves 4'-8' long, few or solitary, large white axillary 

 flowers, and large, russet-colored drupes 3'-6' in diameter. 



Garcinia Xanthochymus Hook, f., East Indian, is a small tree, related to 

 the Mangosteen. A tree 12 high, called "Lemon Squash," was observed at 

 Bellevue in 1913; it has leathery oblong pointed entire leaves about 10' long
