MR. BENTHAM ON TROPICAL LEGUMINOSÆ. 313 
membranaceæ, caducissimæ. Spicæ fulvo-pubescentes, novellæ cylindricæ bracteis alabastrisque im- 
bricatis, per anthesin oblongæ, rhachi demum 1-14-pollicari. Bracteæ, orbiculatæ, concavæ, 2 lin. 
longæ, caducissimæ. Pedicelli vix ulli. Bracteole obovato-orbiculatæ, concave, 3-4 lin. longæ, per 
anthesin patentes. Calycis segmenta squamiformia 1-5, sepius 2, inæqualia, oblonga v. linearia, 
rarissime lineam excedentia. Petala sæpius 0, rarissime adsunt 1-2 minuta. Stamina 10, breviter 
exserta, basi in cupulam brevem irregulariter connata. Ovarium breviter stipitatum, dense villosum, 
ovulis ad 6; stylus glaber, stigmate truneato. Legumen 3-4 poll. longum, 14-13 poll. latum, 
coriaceo-sublignosum, læve, sutura superiore incrassato-dilatata. 
Hab. Tropical Africa. In woods of the Huilla district of Angola, rather frequent between Mumpulla 
and Nene, and between Morino and Lake Tvantala (Welwitsch). 
Var. parviflora. Bracteoles scarcely 3 lines long, but every other character precisely 
as in the western specimens. Robeho mountains, in Zanguebar, at an elevation of 
4700 feet (Speke and Grant, who observe that the bark is made into kilts, cloths, 
band-boxes, huge grain-stores, mats, roofing for camp-huts, &c., and that a blood-red 
juice exudes on cutting the bark). 
Var. (?) grandiflora. Bracteoles rather above 4 Hines long, and flowers not quite so 
sessile, but otherwise the same. Summits of the Sierra da Hella in the Huilla 
district, at an elevation of 4000 feet, with flowers and young leaves at the ends of the 
branches, otherwise nearly leafless ( Welwitsch). 
3. B. APPENDICULATA. (Plate XLII.) Foliolis 3-6-jugis ovali-oblongis lanceolatisve vix 
coriaceis glabris breviter petiolatis, racemis confertis subramosis, pedicellis brac- 
teolis subæquilongis, ovario longe stipitato. 
Arbor 20-40-pedalis, inflorescentia excepta, glabra ; foliola secus petiolum tenuem per paria dissita, 1-2- 
pollicaria, acuminata v. obtusa, obliqua, falcata v. basi inæquilatera v. rarius subæqualia, multo 
tenuiora quam in speciebus præcedentibus, pennivenia et venulosa. Stipulas non vidi. Glandule 
parvæ vesiciformes ad basin foliolorum sæpe stipellas mentientes. Racemi dense multiflori, oblongi, 
breviter pedunculati, 1-2-pollicares, solitarii simplicesque v. basi ramo uno alterove instructi. Bracteæ 
minimize, lineares, caducissimæ. Pedicelli graciles, ad 3 lin. longi. Bracteolæ 2-2} lin. longs, late 
obovatæ, concavæ, extus tomentellæ, per anthesin patentes. Calycis segmenta squamiformia sepius 
2.3. Petala nulla invenimus. Stamina 10, bracteolis dimidio longiora, filamentis gracilibus basi 
breviter connatis; antheræ glandula minuta apiculatæ. Ovarium longiuscule stipitatum, breve, 
margine ciliatum, ovulis 5-6. Legumen 3-4 poll. longum, 14-13 poll. latum, sutura superiore in- 
crassato-dilatata. 
Hab. East tropical Africa. Highlands of the Batoka Country and about Zomba, on Lake Shirwa, the 
fibrous bark one of those used for cloth by being beaten out, and the seeds eaten (Kirk).
