as belonging to Jack's I. icosandra. The fruit is only imperfectly 10- 

 celled in this species, the vertical processes from the back walls of the 

 culls of tlie capsule being incomplete. In the next species they are 

 nearly quite complete, and its capsules are really 10-celled. 



2. IxoNANTHBS RETICULATA, Jack in Mai. Miscel. II, No. 7, 51 ; Hook. 

 Comp. Bot. Mag. I. 154. A small tree, occasionally only a shrub. Leaves 

 coriaceous, not black when dry, elliptic, sometimes elliptic-rotund, the 

 apex blunt, the base cuneate ; main nerves 7 or 8 pairs, slightly pro- 

 minent when dry, interarching "25 in, from the edge ; length 3*5 to 5 

 in., breadth 2 to 2"75 in., petiole '6 to '8 in. Cymes on stout peduncles, 

 few-flowei'ed. Floivers ovoid to ovoid-rotund, scarcely opening, '3 in. 

 long", petals broadly elliptic ; stamens about 10, the filaments much 

 longer than the petals. Capsule 1-35 to l'?5 in, long, 5-valved, 10- 

 celled. Hook. fil. Fl. Br. Ind. I, 417; Griffith Plant. Cantor, 11. 

 Hypericinea macrocarpa, Wall. Cat. 4833. Gordonia decandra, Roxb. 

 Fl. Ind. ii., 573 ; Wall. Cat. 4408. 



In all the provinces except the Nicobar and Andaman Islands. 

 DiSTRiB. Sumatra. 



In this species the 5 cells of the fruit are converted into 10 by 

 a dissepiment springing from the wall of each valve. I have never seen 

 the seeds, all the capsules I have met with being empty. 



Order XXI. MALPIGHIACE^. 

 Trees or shrubs, often climbing. Leaves (in the Indian genera) 

 opposite, quite entire; stipules small or 0. Inflorescence axillary or 

 terminal ; pedicels articulate, usually 2-bracteolate. Floivers middling- 

 sized or small, white or yellow, more rarely red, yellow, or blue, herma- 

 phrodite, regular or irregular. Calyx usually 5-partite ; segments im- 

 bricate or valvate, 1 or more (never all) furnished with a large gland, 

 rarely eglandular {Aspidopterys). Petals 5, clawed or not, often fim- 

 briate, imbricate. Disc obscure. Stamens 10, hypogynous or subperi- 

 gynous, equal, or 1 or more much larger than the others, filaments free 

 or connate below, anthers 2-lobed. Ovary 3-celled ; styles 1-3, rarely 

 4, straight or circinate, stigmas capitate or punctiform or lateral ; ovules 

 solitai'y in each cell, micropyle supei'ior, raphe ventral. Fruit (in all 

 the Asiatic genera except Brachyloplion) of one or more winged samaras. 

 Seed exalbuminous ; embryo straight or curved, radicle superior. — 

 DiSTRiB. An order, largely represented in America, but scantily in Asia ; 

 genera about 50, species about 620. 



Styles 1 rarely 2 ; calyx glandular. 



Fruit of 3, united, many- winged samai-as ... 1. Tristellateia.
