 cuous disk. Ovary sessile or rarely shortly raised on a thick columnar 

 torus, free or more or less confluent with the disk, 3-5-celled ; style entire 

 or lobed ; stigma simple or lobed. Ovules 2 (rarely 1) or 6o, anatropous, 

 erect or ascending. Fruit a capsule, drupe, or subapocarpous and often sama- 

 roid. Seeds sometimes winged {Hippocratea), with or without a fleshy 

 albumen, frequently arillate. — Shrubs or trees, occasionally spinescent or 

 scandent. Leaves opposite or alternate, most frequently coriaceous, simple. 

 Stipules minute or 0. Inflorescence cymose, axillary or terminal. Flowers 

 small, greenish yellowish or white. 



A cousiderable and wide-spread ligneous Order, most frequent in warm countries. One 

 mouotypic genus is confined to tropical Africa. 



Stamens as many as petals. 

 Ovules 2 in each cell. 



Leaves alternate. Fruit a capsnle 1. Celastrus.

1. CELASTRUS, Linn. ; Benth. et Hook. f. Gen. PL i. 364. 



(Gymnosporia, Wight ct Am. ; Benth. et Hook. f. 1. c. 365.) 



Flowers frequently polygamous. Calyx 5-partite or 5-fid. Petals 5, 

 sessile, usually spreading. Stamens 5, inserted upon or under the margin ot 

 the disk; anthers dehiscing longitudinally. Ovary 2-3-(rarely 4-)celled, 

 free or more or less confluent with the disk ; style short ; stigma with as 

 many lobes as cells in the ovary or subcapital. Ovules 2 in each cell. 

 Capsule globose or obovoid, often trigonous, 3-2-1-celled, with 1 or 2 seeds 

 to each cell, dehiscing loculicidally. Seeds with a fleshy albumen, frequently 

 more or less invested by a fleshy* arillus. — Shrubs or trees frequently armed 

 with axillary spines. Leaves alternate, usually more or less coriaceous and 

 serrulate or toothed. Flowers small, in (African species) axillary forking 

 cymes or pedicels simple, fasciculate. 



A large genus widely distributed in the warmer and tropical countries of the Old World- 

 The tropical African species appear to be endemic with the exception of one wide-spreaa 

 species, C. senegalemis. The species do not admit of being separated by decisive characters 

 in an analytical table. 

 Peduncles forking. Armed or unarmed. 



Leaves acute, 3-6 in., elliptical, serndate. Peduncles 1J-34 in., 



slender. Ovary half-immersed \. C. gracilipet- 



Leaves acute (or the fasciculate leaves obtuse), oblanceolate or 

 oblanceolate-rhomboid, much narrowed below, 2-3 in. Ovary

 narrowed below, glaucescent, serrulate or entire, J-4 in.
