90. INDIGOFERA. Shrubs or shrublets having usually imparipinnate but sometimes 3-foliate or i-foliate leaves, and axillary few or many-flowered racemes or clusters of 
white, rosy, or purple flowers. Calyx small, green, 5-toothed. Standard roundish, reflexed ; wings narrow, partly adherent to the keel, which has a wart or spur on 
each side near the base ; upper stamen free, the other 9 connate ; connective with a glandular point. Ovary sessile, usually many-ovuled, sometimes 2 or few- 
ovuled. Pod usually linear, terete or more or less flattened, dehiscent, the seeds often separated by septa. Pubescence often strigose. A large tropical and sub- 
tropical genus of herbaceous or woody undershrubs, never of timber size, but of interest as the source of indigo, which is obtained from the macerated leaves of 
several (or many) species. Among those which yield commercial indigo are I. tinctoria, I. anil, I. hirsuta, I. cndecaphylla, and I. arreeta, all of which occur in the 
Province, but the presence of colour is not known to the natives, who have no use for these plants. In the “Flora of Tropical Africa” the two first-mentioned 
above are spoken of as cultivated ; this does not apply here however, for I did not see a single plant of any Indigofera under cultivation. The native names appear 
to be more or less generic, and are, 6, Nkaromeba ; 10, Sa-wayo. There has of late been a demand from India for seed of colour-yielding Indigoferae, and the 
culture of plants for seed may be worth attention even though the cost of labour may prevent actual indigo extraction locally. See “ Forest Flora of Cape Colony,” 
199, Plate LIV. fig. 3. 
91. DALBERGIA. Trees, shrubs or climbers, often spine-bearing, and having alternate imparipinnate leaves with alternate or sub-opposite leaflets, and corymbose axillary or 
terminal panicles of small white or yellow flowers. Calyx 5-toothed, the teeth unequal, the lower one longest. Petals clawed, the side ones narrow ; the keel petals 
connate at the point, enclosed in the standard. Stamens 10, connate, the tube having 1 or 2 slits, or 1 stamen absent. Ovary stalked, 1 3 ovuled. Pod compressed, 
oblong, usually i-seeded, not winged, indehiscent. Many tropical species, mostly climbing forest weeds, but various Indian and Brazilian species yield valuable 
timbers, usually having black or purple heartwood ; the best known is the Sissoo tree (D. Sissoo, Rox.), now extensively cultivated in India. Of the 5 species 
recorded from this Province 4 are climbing shrubs, often monkey ropes, but in the absence of support forming semi-erect shrubs, to which the names, 6, Tiriane ; 
10, Sambelemu, are given. A similar rambling shrub is D. obovata, E. Mey, common in Lourenzo Marques and M’Chopes. See “ Forest Flora of Cape Colony,” 
199, Plate LI. fig. 2. An erect unarmed shrub 3-5 metres high in the northern forests, and constantly bearing fruit-like galls, but not seen in flower or fruit, is 
believed to be a Dalbergia, and is known as, 10, Munyenye. 
D. melanoxylon, Guill. & Perr., has the reputation of being one of the valuable timbers of this Province, and is known as, 1, Ebony ; 2, Grenadilha ; but though 
constantly looked for I found nothing to answer its description, and doubt its presence in any quantity. It is thus described in “Flora of Tropical Africa” : “A 
copiously branched bush or small tree, 15-20 feet high, with stout woody glabrous branches and long sharp woody spines. Petioles under 4 -in., glabrous ; leaflets 
9-13, short stalked, oblong or obovate, in. long, both ends rounded, often emarginate, sub-coriaceous, both sides glabrous, veins beneath raised. Flowers in 
copious terminal and axillary panicles, the latter equalling or shorter than the leaves. Pedicels a line long, slender, glabrous, bracteolate. Calyx 2 lines deep, 
glabrous, upper teeth deltoid, the lowest lanceolate. Corolla yellow, slightly exceeding the calyx. Pod $-2 in. long, J-in. broad, blunt or sub-acute, with a long 
pedicel, the valves glabrous and membranous. Seeds 1-4. Mozambique, Dr. Peters ; Zambesi-land, Dr. Kirk ! Dr. Meller,” and also recorded from Scnegambia, 
Nubia and Abyssinia. 
92. MILLETTIA. Trees having imparipinnate leaves, usually opposite stipellate leaflets, and terminal panicles of purple flowers. Calyx companulate, with broad lobes, 
Standard large, roundish, reflexed ; wings smaller ; keel still smaller, incurved. Stamens monadelphous, the upper stamen free at the base but not above. Ovary 
many-ovuled, style inflexed. Pod compressed, several-seeded, ligneous, tardily dehiscent. Stipules small. 
M. caffra, Meisn. Ver/i. names— 5, Umsia ; 6, 7, S, Songa ; 13, Umzimbiti, or Umzimbeet. Usually a small gnarled tree preferring shallow shale soils ; occasionally a 
large tree on alluvial. Leaves 15 c.m. long, 10-12 c.m. wide, the leaflets in about 5 pairs, oblong-acute, glabrous above, silky below, shortly petioled on a pubescent 
rachis. Panicles foxy-pubescent, terminal, 8-12 c.m. long. Flowers purple; calyx and vexillum silky, calyx-lobes acute. Pods 15 c.m. long, 3 c.m. wide, several 
seeded, woody, dark-velvety, the valves twisting much on dehiscence. Seeds 2 c.m. long, oblong, flat. Cut roots make new plants. Used largely in Natal for 
wagon spokes, &c See “Forest Flora of Cape Colony,” page 203 and Plate LV. Present but not common in Lourenzo Marques district, Lower Gaza, M’Chopes 
and Inhambane, usually as a bush or small tree. 
93. SAL DAN I A.' (New genus.) 3 Flowers not seen ; peduncle i-flowered, bracted near the middle ; calyx 5-fid, segments acute ; legume flat, dehiscent, several-seeded (3-5), 
set with short spines or strong hairs. Leaves abruptly pinnate. An unarmed tree. 
' Named after Dr. Saldanha, through whose influence the development of the Province has been actively taken in hand, and on whose fine farm at Umbelusi this tree grows. 
* SALDANIA. (Gen. nov.) Arbor inermis. Pedunculo unifloro, ad medium bracleato. Calycis 5-fidi segmentis aculis. Legumine dehisccntc piano, aculeis brevibus val setis vestito, 3.5- 
spermo. Foliis abrupte pinnatis. Floris struclura non cognita.
