282 XXX. malpighiacE-e; (oliveh). [Triaspis. 



coriaceous, elliptical or oblong-elliptical, obtuse or rather broadly cuspidate 

 and somewhat acute, broadly rounded or occasionally subcordate at the base, 

 entire, appressed rusty-pilose at first, early glabrescent above and beneath 

 excepting usually the' midrib, 2-4 in. long, 1^-2 in. broad or sometimes 

 larger ; petiole 1-4 lines. Flowers rose-coloured, in axillary shortly pedun- 

 culate umbels, much shorter than or occasionally equalling the leaves ; pedun- 

 cles often 2 or 3 together or from a very short or obsolete axillary branch ; 

 pedicels slender, \- f in., rusty-pilose, with scaly bracts at the base. Sepals 

 oblong-lanceolate, obtuse. Petals clawed, reflexed ; lamina entire or slightly 

 denticulate. Filaments filiform. Ovary glabrous. Fruit-wings very thin, 

 6-10 lines broad and long, broadly 2-partite above, truncate or broadly re- 

 fuse or 2-fid below ; usually produced nearly twice as much below the carpel 

 as above and nearly all the reticulating nervures directed downwards.
