278 xxx. malpighiace.e (oliveb). [Acridocarpus. 



in. broad ; petiole \-\ in. Flowers in terminal simple branched or panicu- 

 late rusty-pubescent or -tomentose racemes often considerably overtopping 

 the leaves, frequently also in shorter axillary racemes. Pedicels slender, \- 

 f in. ; bracts triangular, acute, tooth-like,' 1 line or usually less. Calyx 

 variously thickened at the base, usually with 1 disciform gland alternating 

 with 2 of the lobes. Wing of samara oblong or obliquely oblanceolate, 

 more or less curved towards the obtuse extremity, 1J— \\ in. long, •J— f un. 

 broad, the base of the wing half-clasping the nut or slightly narrowed and 

 not broader than the nut. — Heteropterys ? Smeathmanni, DC. Prod. i. 592.

Var. o. Wing of the fruit narrowed to the nut.

 precise locality.) 



Var. 0. Base of the wing half-clasping the nut.

The leaves vary considerably in texture in our specimens, bnt not more than is frequent 

 in climbers which have their lower branches in the shade and their upper exposed. The 

 differences in the outline of the samara may be more important than I have been led to con- 

 sider them, although they are but slight absolutely. Unsupported, however, by other 

 characters, I cannot regard them as of specific value. 



2. A. plagiopterus, Guill. et Perr. FL Seneg. i. 123. t. 29. Very 

 nearly allied to A. Smeathmanni, but with the leaves obovate-elliptical or 

 broadly elliptical, rounded or retuse at the apex with a very short (1-2 lines) 

 or obsolete or subacute cusp, obtuse or narrowed to the base with lateral 

 petiolar glands, 3-5 in. long, 2-2^ in. broad. Bracts ovate or ovate-lanceo- 

 late, concave, \ in. Calyx-glands nearly obsolete on 1-3 of the lobes. 

 Fruit-wings about \\ in., narrowed at the base, widely divergent according 

 to Guillemin and Perrottet. — Anomalopteris obovata, Don, Gen. Syst. i. 642.

3. A. corymbosus, Hook. f. FL Nigrit. 246. t. 24. Extremities 

 slender, glabrous or very early glabrescent. Leaves alternate, firmly mem- 

 branous, oblong-elliptical, subacute or cuspidate, rounded or slightly narrowed 

 at the base, entire or undulate-denticulate, glabrous, 2|-4 in. long, 1-2 in. 

 broad, with or without the basal glands. Flowers in very short corymbose 

 racemes, terminal or on short axillary shoots. Pedicels slender, spreading 

 rusty-pubescent, |-f in. Bracts subulate, rather rigid. Calyx with 1-4 

 sunken glands. Wings glabrous, either rather broader above oV broadly ob- 

 long, 1 in. or less m length, diverging at 70°-80° in our specimens, still red 

 or purple when dry.

This may prove to be the Malpighia aUernifolia ol Schumacher and Thonning, cited 

 with doubt as a synonym of A. Smeathmanni.
