young leaves pubescent, as also the peduncles which are 2-4 c.m. long, and many-flowered. Petals united J their length. Staminal tube nearly as long as the petals. 
Pod 8-15 c.m. long, 3-4 c.m. wide, flat, thin, dry, membranous, indehiscent, transversely streaked, with many hard brown seeds in separate sections, each seed with 
a scar on each side near the base. Abundant near Lourenzo Marques, seldom if ever of timber size. See “ Flora Capensis” (Harv. & Sond.) II. 284.

A. umbalusiana. (New species.) 1 Fern, names 4, 15, Nala-nyaca, or Nala. Shrub 2-4 metres high, nearly or quite deciduous, with numerous sharp spines 5 10 c.m. 
long, bearing leaves and peduncles; or sometimes a bushy tree 7-10 metres high with fewer spines. Stipules 3 nun. long, hardly prickly. Leaves 5-8 c.m. long and 
wide, rachis with a gland near the base, pinnte 2-3 pairs, leaflets 2-5 pairs 7-10 m.m. long or gradually larger upward to 2 c.m. long, obliquely elliptical or more or 
less trapeziform, rounded or somewhat pointed. Peduncles 1*5-3 C.m. long, 6-12 flowered; pedicels 3-5 m.m. long; calyx 2 m.m. long ; corolla 5 m.m. long, divided 
at the top only; staminal tube included; filaments 1*5-2 c.m. long, pods 8-12 c.m. long 1*5-2 c.m. wide, rounded to a point, tapering somewhat at the base, thin, flat, 
3-5 seeded, dehiscent. Seeds round, compressed, 7 m.m. wide. Bark smooth. Roots used for stomach medicine. Frequent in Lourenzo Marques and Maputa 
districts in the thorn-veld and up to the Lebombos. Sim 6200.

A. mossambicensis. (New species.) 2 Vern. name — 4, Impesha. A large tree 12-20 metres high, and 60-100 c.m. diameter of stem with useless timber and rough bark 
used as ashes with snuff. Leaves 2-pinnate, rachis 15 c.m. long pubescent, with a sessile gland near the base; pinna; 3 pairs 7-10 c.m. long, each with rachis swollen 
at the base; leaflets 3-4 pairs, the upper the larger, 3-5 c.m. long, obliquely elliptical, ovate or obovatc, usually rounded or bluntly pointed at the apex, tapering to 
the 2-3 m.m. petiole on the lower side but parallel with the rachis or nearly so on the upper side, and finely tomentose on the lower surface, but soon glabrescent on 
the upper. Peduncles axillary, with 10-15 sessile flowers on top. Calyx tubular, 4 m.m. long, with short equal teeth; corolla longer by half, with short lobes; 
peduncle, calyx and corolla densely pubescent; staminal tube included, filaments 2 c.m. long. Pods 12-18 c.m. long, 2-3 c.m. wide, shortly pointed, rounded at the 
base to the 1-1*5 c.m. stipe, flat, membranaceous, 8-10 seeded, and with a distinct margin on each side. Frequent throughout the Province, semi-deciduoua, flowering 
in early summer. Sim 6392.

Between Arenga and Bajou, Magenja da Costa were trees leafless when seen, and with red pods, and known locally as gamaranga or Mukratabo, which appear 
to belong to this species but may be a different closely allied one. 
A. fastigiata, E. Mey. Vern. names — 1, Flatcrown ; 4, Goine ; 5, M-bezwa ; 6, Mo-esu, or O-heso ; 10, Maranga ; 13, Umhlandhloti and Ncbeiele. A tree 7-20 
metres high, 30-60 c.m. diameter of stem, having a clear bole and widely expanded, flat crown 12-15 metres diameter. Leaves usually deciduous, and the white 
twigs are conspicuous during winter. Leaves alternate, bi-pinnate, 15-25 c.m. long, 15 c.m. wide; rachis up to 15 c.m. long with a sessile gland near the base ; 
pinnte 5-6 pairs, leaflets 6-12 pairs, each leaflet 12-18 m.m. long, 6 m.m. wide ; upper pair rather smallest. Heads corymbose toward the end of the branch, axillary 
with or without produced leaves, 2-10 in an axil, 3-4 c.m. wide, with 50 or more flowers, each flower sub tended by an acute involute rusty bract ; the flowers sub- 
sessile, and mostly hermaphrodite, but 1 or more are staminate in each head. In the hermaphrodite flowers the stamens are indefinite (15-30), the filaments united 
for about 3 c.m. and free and sub-erect for 1 c.m., while the slender pistil extends 1 c.m. beyond the top of the staminal tube. In the central staminate flower or 
flowers the pistil is absent, the to-toothed calyx is larger, the corolla shorter, the staminal tube wide and full of nectar, and shorter than the corolla which is hid by
