tinctly clawed, while in T. Hornemannianum they are rudimentary. This character 

 may prove inadequate, in which case the two plants must he reunited under the spe- 

 cific name verrvcosum, first applied to*the Madagascar plant. Hayne, in his original 

 publication of TrachyloUum, in Flora (1827, ii. 473), describes the petals as 5, sub- 

 equal ; but in his " Arzneigewachse" (xi. t. 18 and 19) gives T. Gcertnerianum and 

 T. Homemannianum as tripetalous. 



26. CRUDIA, Schreb. ; Benth. et Hook. f. Gen. Plant, i. 584. 



Calyx-tube short, turbinate, segments 4 (-5), thin, broadly imbri- 

 cate, at length reflexed. Petals 0. Stamens 10 (or fewer), free ; fila- 

 ments filiform, anthers elliptical, versatile, dehiscing longitudinally. 

 Ovary shortly stipitate, narrowed above and below; style slender, 

 stigma small, terminal ; ovules few. Legume (not seen in the African 

 species) " obliquely orbicular, ovate or broadly oblong, flat, rigidly 

 coriaceous, 2-valved, often with thickened margins. Seeds 1 or 2, 

 large .... exalbuminous." — Unarmed shrubs or trees. Leaves un- 

 equally pinnate. Stipules small, caducous or (in following species) 

 rather large subpersistent. Flowers rather small, racemose. Bracts 

 and bracteoles minute, deciduous. 



A small genus, chiefly Tropical American, with but 1 species African, and 1 or 2 in 

 the Indian Islands. 



1. C. senegalensis, Planch. ; Benth. in Linn. Trans, xxv. 314. A 

 shrub or small tree, wholly glabrous. Leaves 4-7-foliolate. leaflets 

 alternate, submembranous or at length coriaceous, elliptic-oblong or 

 varying from ovate to obovate-elliptical, shortly acuminate or apiculate, 

 base slightly unequal, more or less rounded, reticulation subprominent 

 or not conspicuous, 2-4 in. long, \-2\ in. broad; petiolules 1-2 lines. 

 Stipules erect, rather rigid, venose, ovate-lanceolate or lanceolate acumi- 

 nate, connate below on the inner margins, \- 1 in. long. Racemes ter- 

 minal, often on lateral branchlets or extra-axillary, rather laxly many- 

 flowered, 3-6 in. long. Pedicels slender, J-f in. long. Bracts and 

 bracteoles at base or below the middle of pedicel, minute, deciduous, or 

 bracteoles present at flowering. Calyx- tube very short, turbinate, 

 segments broadly elliptical, subequal, 2-3 lines long. Filaments gla- 

 brous. Ovary densely villous, narrowed below into the' short free 

 stipes, above into the slender at length glabrous style ; ovules 5-6. 

 Legume not seen.

M. Baillon rinds occasionally 5 sepals (Adansonia, vi. 200). A specimen of prooably 

 the same species is in the British Museum Herbarium from S. Leone (Afzelius), with 

 an immature fruit — compressed about 1 in. long and nearly as broad, very oblique, 

 the valves coriaceous, transversely rugulose, tawny-tomentose. 



27. DETARIUM, Jussieu; Benth. et Hook. f. Gen. Plant, i. 585. 



Calyx divided nearly or quite to the base into 4 (rarely 5) segments, 

 subvalvate with very narrowly bevelled imbricate margins. Petals 0.
