(Herb., D., Th.) : 
A small annual. Flowers minute, yellow. Known from the following by the 
more prominent reticulations on the sides of the legume, and the shorter, curved but 
not hook-pointed prickles. 
3. M. nigra (Willd. Sp. 3. p. 1418); diffuse or erect ; leaflets obovate 
or obcordate, toothed ; stipules laciniate; peduncles 2-3 flowered ; ca- 
lyx-teeth subulate; legumes bordered with a double row of long, seta-— 
ceous hook-pointed prickles, flat at the sides and somewhat netted-veined, 
several times spirally and closely twisted. DC. Prod. 2,p. 178. EF. & Z.

Very like the last, but with longer and narrower calyx-segments, and much longer 
and more bristle-shaped, hook-pointed prickles on the legume. The Cape plant 
agrees with European specimens in Herb. T.C.D. I describe from those collected 
by Williamson. 
1,M. laciniata (All. Fl. Ped.n. 1159); erect or diffuse ; leaflets cuneate 
or linear, coarsely inciso-dentate, truncate, mucronulate; stipules inciso- 
dentate ; peduncles 1-2 flowered, short; calyx-teeth short, acute, nar- 
row; legumes bordered with a double row of subulate, hook-pointed 
prickles, thickened at the margin, with flat sides, and two or more times 
spirally twisted. DC. Prod. 2,p. 180. £. & Z./ 1504. H. Mey. in Comm.

Has. Sandy ground, various parts of the colony, E.g 2. Drege! Greenpoint, 
Dr. Pappe! (Herb. D.) 
Known by its deeply cut or laciniated leaflets, which are smaller and more rigid 
and narrower than in either of the preceding. The prickles on the legume are much 
shorter in Cape specimens than on our European examples in Herb. T.C.D. 
XXXI. INDIGOFERA, L. 
Calyx small, campanulate, 5-fid or 5-toothed. Vewillum subrotund, re- 
flexed ; carina with a spur or prominence at each side, near the base. 
Stamens diadelphous; the connective of the anthers apiculate. Ovary 
2 or several ovuled, Zegume linear, terete, compressed, or flattened, 1 
or several seeded, mostly with dissepiments between the seeds, Endl. 
Gen. 6530. : 
Shrubs, undershrubs or annuals, very abundant in tropical and subtropical climates, 
Leaves imparipinnate or digitate, 3 or many foliolate, rarely unifoliolate or abortive. 
Hairs commonly strigose, i.e., rigid, fixed by a medial point, and tapering to each 
end, set in subparallel lines. Flowers purple, or rosy, or white. Indigo is obtained 
by fermentation from the foliage of several species of this large genus, whence the 
generic name. 
ANALYSIS OF THE SOUTH AFRICAN SPECIES.

1. Juncifolie. Petioles very long, filiform, acute, mostly leafless ; bearing in the 
young plant only small, terminal, and lateral leaflets, in impari-pinnate order. —

Racemes shorter than the petioles, few flowered ... ... re
