S. capitata, Bolle. Vern. name— 4, Mfofof. A shrub or small tree, frequent in Lourenzo Marques and Maputa, and extending north to Inhambane. Leaves 5-7 c.m. 
long, with a distinctly winged rachis and 4-7 pairs of glabrous, shining, sessile, obovate oblong leaflets 1-2 c.m. long, 1 c.m. wide or less. Flowers numerous in 
dense compact panicles; sepals, petals and stamens crimson. Ovules about 10. Pod 5-6 c.m. long, 3 c.m. wide, elliptical, 5-8 seeded, the seeds each set in a 
yellow aril, the valves breaking away and leaving the keeled circumference carrying the seeds. 
S. brachypetala, Sond. Vern. names— i, Boerbean ; 2, Boer-boon ; 4, Mfofof; 13, Umgxam ; 15, Shimnum-ynan. A medium sized tree, 7-10 metres high, with stem 
30-45 c.m. diameter, and rough dark bark. Leaves alternate, 10-14 c.m. long, 7-10 c.m. wide, with about 4 pairs of ovate or obovate nearly sessile leaflets 3-5 c.m. 
long, 3 c.m. wide. Panicles axillary and terminal, many flowered, calyx crimson ; petals smaller than calyx-lobes ; stamens exserted, monadelphous. Pod 
obliquely oblong, 5-10 c.m. long, 4 c.m. wide, nearly flat, beaked, margined on both sides, about 6-secdcd, with red aril round the base of each seed. Seeds 
varying in form with available space. Frequent in the Lourenzo Marques district, especially on the Lcbombo Range.

1 16. TRACH YLOBIUM. Trees, with the branches often ending in single or branched spines, 2-foliate leaves, terminal panicles of small flowers, and 1-2 seeded berry-like 
fruits. 
T. mossambicensis, klotzsch (in Peters’ Mossamb. Bot., 21, t. 2). Vern. names— 4-8 and 15, Lulu or Nulu, and Mahla-banqucnze . 10, Napige. An erect tree, 
10-15 metres high, with a spreading rounded crown and a stem 45-60 c.m. diameter. Exceedingly variable in regard to pubescence, sometimes densely 
grey-pubescent on all young parts, sometimes quite or almost glabrous. Twigs zigzag at the nodes ; in some conditions of growth the branches mostly abort into 
spines, either simple or more frequently 2-spined (apparently dichotomous), or sometimes several-spined. Leaves 3-5 c.m. long, 2-4 c.m. wide, ovate or ovate 
elliptical, bluntly pointed, oblique at the base, the outer side longest; petiole 1-3 c.m. long, petiolules 4-6 m.m. long. Calyx tube short, with 4 imbricate segments; 
3 petals rounded and clawed, other 2 minute. Stamens 10, free or almost free ; ovary surrounded by a hairy ring at the base ; ovules 4-5. Fruit on a pedicel 1 c.m. 
long, not compressed, 4 cm. long, 2-2-5 c - m - diameter, 4-5 furrowed, berry-like, 1-2 seeded, indehiscent, and said to be edible, though it did not seem so to me. 
Stone (or seed) 4 c.m. long, 15 c.m. diameter, bony. A tree with valuable hard timber; frequent in the extra-tropical districts; present but less common in the 
northern districts. 
This is included as a synonym under T. Hornemannianum, Hayne, in the “ Flora of Tropical Africa,” but is quite distinct from the tree cultivated under 
that name, in having shorter, wider leaflets, always somewhat glaucous, often canescent, and in the presence of spines. T. Hornemannianum is credited with yielding 
part if not all of the Copal of East Tropical Africa.

1 17. COPIAFERA. Closely allied to Trachylobium, but differing in having no petals, the calyx divided to the base, and fewer ovules. The leaves are 2-foliate, and the 
flowers axillary, solitary or in small racemes. Seeds sometimes arillate. 
C. gorskiana, Benth. (= Gorskia conjugata Bolle in Peters’ Mossamb. Bot., 16, t. 3). Vern. name — 4, Nulwane. Seen only as a small tree, but said to grow large, 
much branched, and the twigs pubescent and often ending in simple, dichotomous, or branded spines similar to those of Trachylobium. Leaves a-foliatc, the 
leaflets ovate, very oblique, coriaceous, glaucous, glabrous, 3 c.m. long, 2 c.m. wide. Inflorescence axillary, or in small axillary or terminal racemes; flowers small, 
greenish ; legume oblong, terete, i-seeded, 3 c.m. long, 2 c.m. diameter, yellow when ripe, said to be edible. Seen only at Umbelusi, Lourenzo Marques district, 
but recorded from Zambesia by Drs. Peters and Kirk ; the latter states that the tree affords a good hard timber. 
C. Mopane, Kirk. Vern. name — 16, Mopane. Unknown to me, and not seen in the lower Zambesi forests. “A fine forest tree, the trunk often 2 ft. in diameter; 
extremities glabrous. Leaflets unijugate, sessile, elongate-semi-ovate, outer margin nearly straight to the narrowed obtuse apex, at right angles to the basal margin 
or semicordiform, coriaceous, glandular-dotted and minutely glandular-crenulate, 7-9 nerved, reticulate, 2-3 A in. long, l-ri in. broad at the base ; petiole 1 in. more 
or less. Stipules oblong or ovate, 1-2 lines, deciduous. Inflorescence not seen, but probably in short axillary racemes. Pedicels i i in. Legume flat, thinly 
coriaceous, rather obscurely reticulate, in outline obliquely semi-circular or resembling a somewhat lengthened nautilus from the rounded gibbosity beyond the scar 
of the style ; 1^-2 in. long ; gynophore o, or very short. Seeds reniform or oblong, testa deeply convolute-corrugate with large resinous glands ; cotyledons contort- 
plicate, thin, not resiniferous. Near Bumbo, Angola, Dr. Welurtsch ! Lupata, Zambesi, Dr. Kirk ! Dr. Kirk’s note appended to our Specimens says that this is
