6. B. PANICULATA, sp. n. Foliolis 2-4-jugis ovali-oblongis basi inæquilateris coriaceis 
canescenti-tomentosis glabratisve, racemis brevibus paniculatis, bracteis parvis ca- 
ducis, petalis subæquilongis, 4 spathulatis, summo breviter stipitato, staminibus 10 
basi diadelphis. 
Arbor mediocris, late comosa, 30 pedes attingens, sed jam statu juvenili 5-6 pedes alta frequenter florens. 
Ramuli foliaque novella tomento brevi molli canescentia, adulta sepe glabrata. Foliola 2-4-polli- 
caria, obtusissima v. breviter obtuseque acuminata, rigidule coriacea, petiolulo 1-2 lin. longo, lamina 
tamen latere inferiore fere ad basin petioluli decurrente. Stipulæ parvæ, late, rigide. Racemi breves 
densique, in paniculam ramosam folia superiora sæpe æquantem dispositi, rhachi bracteis bracteolisque 
fulvo-tomentosis, floribus ex albido flavescentibus. Bracteæ orbiculatæ, concave, 1-2 lin. late. 
Pedicelli vix unquam 1 lin. longi. Bracteolæ suborbiculatæ, concavæ, 6-7 lin. longs, alabastra 
includentes, per anthesin patentes. Calycis tubus discifer brevissime turbinatus, vix 1 lin. longus ; 
limbi segmenta 5, rigidule petaloidea, margine ciliata, obovali-oblonga, 2-3 lin. longa. Petala 4 
inferiora spathulata, 4-5 lin. longa, lamina 1-2 lin. lata, 2 infima lateralibus paullo minora ; quintum 
summum interius breviter unguiculatum, late ovato-suborbiculatum, concavum, ceteris paullo 
brevius. Stamina 10, longiuscule exserta, 9 inferiora basi in vaginam fere 2 lin. longam connata, 
decimum summum a basi liberum. Ovarium brevissime stipitatum, breve, villosissimum, ovulis 4—5 ; 
stylus elongatus, glaber, involutus, stigmate peltato. Legumen oblongum, valde obliquum, 2-3 poll. 
longum, 1-11 poll. latum, junius dense tomentosum, demum glabratum, læve nec rugosum. 
Hab. West tropical Africa. Angola district, forming with other Leguminous trees considerable woods in the 
district of Huilla, and, judging from a specimen in fruit only, also in Pungo Andongo (Welwitsch). 
This species, in its small flowers, short calyx-tube, and reduced petals, forms some 
approach to the genus Brachystegia, and differs from that, as well as from the true Ber- 
linias, in the stamens diadelphous at the base; but this character does not appear to be 
of sufficient importance for its separation from the latter genus, with which it is closely 
connected through B. angolensis. 
Var. ? ferruginea, foliis molliter fulvo-villosis. Rare near Mumpulla in the Huilla 
district (Welwitsch). ; 
The specimen is in fruit only, but appears to differ from the normal form only in the 
indumentum.
