 exstipulate leaves. Tristellateia, Hiptage, Aspidopterys, Triopterys, Tetrapterys, Hircea, &o. 



Teibe IV. GAUDiCHAUDiE.a5. — Stamens 8 or fewer, some or all of those opposite the petals, 

 and sometimes others, anantherous. Style 1. Carpels winged or not, usually pendulous from 

 a raphe-like thread. — Erect or climbing ; leaves often alternate. Flowers often dimorphic.

Malpighiaccm are near Erijthroxylece (which see), Aeerinem and Sapindacece ; they are separated from 

 Acerinece by their glandular calyx, long clawed petals, monadelphous stamens, usually 3-merous fruit, 

 1-ovuled ovarian cells, curved ovules, and superior radicle. The affinity is still more close with Sapin- 

 dacece, from which they only differ in the inconspicuous disk and solitary abnormally-formed ovules. 

 Malpighiaceee mostly inhabit the plains and virgin forests of the southern tropic of America ; they are less 

 numerous beyond this region, rarer still in equatorial Asia, and very rare in Africa and Australia. 



Many Malpighiaceee owe to the colouring matter and tannin contained in their bark astringent 

 properties, which are useful in various disorders, and especially in dysentery and intei-mittent fevers ; as 

 the different species of the American genus Byrsonima. The acidulous-sugary fruits of Mcdpighia wens and 

 glabra are recommended as refreshing and antiseptic.
