(A form with smaller oblanceolate leaves.) 
_ Cassipourea congensis, R. Br., DC. Prod. iii. 34, may be the same plant, as suggested 
in “ Fl. Nigrit.” 342, and the same or a very near ally grows at Natal (Gerrard, 1655). 
2. 'W. plumosa, Oliv. Tree of 30 ft.; terete branches and foli- 
age glabrous. Leaves thinly coriaceous, elliptical or oblong-ellip- 
tical, narrowed into a distinct rather obtuse acumen 4— in. long, 
base slightly rounded or cuneate, obsoletely undulate-crenate above ; 
2-34 in. long without the acumen, 1} to nearly 2 in. broad; petiole 
% in. Flowers sessile or subsessile in axillary fascicles of about 3—5 or 
solitary. Bracteoles very minute. Calyx glabrous externally, 4-fid, 
campanulate, lobes ovate, appressed setose-hirsute within. Petals 
considerably exserted, elongate-spathulate with slender claw, lamina 
closély fringed, lacinie plumose. Stamens 1-seriate, subhypogynous, 
about 28-30; filaments filiform, anthers oblong-elliptical. Ovary 
sheathed by free calyx-tube, densely setose-hirsute; style appressed, 
hispid, rather stout, much exceeding the ovary; stigma 2-lobulate.

3. ‘W. Afzelii, Oliv. Terete extremities and foliage glabrous. Leaves

solitary; bracteoles microscopic. Calyx glabrous outside, appressed- 
hispid within, deeply 5-fid, lobes erect, ovate-lanceolate. Petals ex- 
Serted as in W. plumosa. Stamens 10, 5 being opposite to the petals, 
subhypogynous. Ovary setose-hirsute, 3-celled, wholly free.
