Hab. Unyoro, Oct. 1862 (Justicia? no. 2, App. Speke’s Journ. 643), Col. Grant ! 
The species ought to retain the specific name under which it was first referred to the correct 
genus. 
[Root fibrous ; stem four-cornered, jointed, and tapering rapidly upwards, here and there purplish, and 
covered with curved hairs; leaves soft-textured ; corolla white, one of its lips larger than the other 
four; pistil the same length as the longest stamina. The seeds are flat as a lozenge, but bordered by 
numerous points, and somewhat oval in general outline. Found in rank vegetation at Unyoro in October.

SESAME. 
1. SESAMUM INDICUM, L.; App. Speke’s Journ. 642. 
Hab. Mininga, April 1861, Col. Grant! Widely cultivated in the Old-World 
tropics. 
[Cultivated at Mininga, Karagué, Uganda, Unyoro, and Chopeh, where it grows healthily, 34 feet high. 
Flowers pale rose-coloured. The seeds are pleasant eaten roasted, and from them the people express an 
oil. It is called “ mafoot’a,” or oil-plant.—J. A. G.] 
2. SESAMUM INDICUM, L., var. ? angustifolium. 
Folia 3-4 poll. lata. 
Hab. 5° 8. lat. (Sesamum по. 4, App. Speke's Journ. 648), Col. Grant ! 
We have apparently the same plant from Mr. Consul Petherick, and also from the Rovuma river, 
collected by Dr. Meller. It may prove a distinct species. 
3. SESAMUM MACRANTHUM, Oliv., sp. nov. Caule erecto, parce ramoso, profunde 4- 
sulcato, pilosulo, deinde glabrato; foliis suboppositis, ovato- уе! oblongo-ellipticis, obtusis, 
interdum mucronatis, repando-crenatis subintegrisve, brevissime petiolatis, supra obsolete 
hispidulis glabrescentibus, subtus breviter incano-tomentosis, reticulatis ; racemis termi- 
nalibus foliaceis, floribus biuncialibus; calycis lobis lanceolatis, acutis; corolle tubo 
basi obtuse gibboso; ovario pubescente. 
Caulis 6-8-pedalis. Folia superiora 2-3 poll. longa, 1-1 poll. lata ; petiolus 7,-3 poll. v. folia subses- 
silia. Pedicelli 1-2 lin. longi. Calyx lobis 5-6 lin. longis, å poll. latis. Corolla infundibulari-campa- 
nulata, limbi 14-2 poll. diam. lobis obtusis. Fructus maturus..... 
Hab. 5° 8. lat., alt. 3800 feet (Sesamum no. 2, App. Speke's Journ. 642), Col. 
Grant! 
[This was common in moist places at 5° and 2241! S. lat., altitude 3000 to 4000 feet. Growing like the 
foxglove, and attaining a height of 8 feet in rank vegetation.—J. А. G.]

Pistil. Mr. Fitch has represented all the leaves as mucronate. In one of our specimens 
they are as figured ; in two others the mucro is nearly or quite wanting. 
4. SESAMUM MACRANTHUM, Oliv., var. ? angustifolium. A plant similar to the last 
as to large flowers, and calyx-segments broader than in 5. indicum, but with narrowly 
oblong obtuse leaves. Тһе capsules resemble those of 8. indicum; but the calyx 
is not persistent, and the disk of the seeds is minutely tubercled or radially cor-
