550 XCVII. PEDALINE# (STAPF). | Rogeria. 
Also in South Africa. Miss Elliott’s specimen has the corolla-tube more 
widened at the base (4 lin. across) so that it might be described us shortly saccate, 
and th: leaves are much smaller than in the type (1 in. long) and rather penni- 
nerved with an indication of 3 lobes. It .is possibly the same form which Engler 
described as var. triloba. 
3. R. bigibbosa, Lngl. Jahrb. x. 256. Stem stout, like the whole 
plant nearly-glandular all over, swollen and about 5 lin. thick at the 
middle; internodes 10-15 lin. long. Leaves ovate, coarsely sinuate- 
dentate, 13-2 in. long, 1-14 in. broad ; teeth 2-24 lin. long; petioles 
up to 10 lin. long, persistent. Fruits on short, arrested, leafy branch- 
lets. Capsule 12 in. long, 7-8 lin. in diam. where widest, beak ome 
forwards, base bulging out posticously into 2 gibbosities. Seeds 15 lin. 
long.

6. SESAMUM, L.; Benth. et Hook. f. Gen. Pl. ii. 1059. 
Calyx small or middle-sized, 5-partite, usually suboblique. Corolla 
obliquely campanulate ; limb more or less oblique, obscurely 2-labiate, 
lowest lobe usually distinctly longer than the others. Stamens sub- 
didynamous, inserted low down in the corolla-tube, not conniving; 
filaments slender, filiform; anthers dorsifixed, cells parallel, dehiscing 
longitudinally to the base. Disc annular, equal. Ovary 2-celled ; cells 
divided by a spurious septum almost to the apex ; ovules numerous, 
l-seriate in each division. Capsule oblong, slightly compressed con- 
trary to the septum, localicidal towards the base, more or less beaked, 
without any lateral appendage at the apex. Seeds numerous, com- 
pressed, obovate——Annual or perennial, erect or procumbent herbs. 
Leaves membranous, sometimes rather firm, petioled or the upper sub- 
sessile, polymorphous. Flowers solitary in the axils of the leaves on 
mostly very short pedicels, pale pink to deep purple. 
Species about 18, some extending to South Africa and India. 
* SesaMorypus. — Plants distinctly (though some- 
times sparingly) pubescent or long-hairy to 
villous. Leaves undivided, rarely the lower 
3-foliolate or 3-partite. Seeds with more or 
less acute margins, rarely with a narrow 
membra:ous rim (8. antirrhinoides) ; faces rugose 
or smooth. 
Prostrate herbs. 
Leaves about as long as the internodes, obtuse at the - 
base, shortly but distinctly petioled . ‘ . 1. 8. Heudelotii. 
Leaves much longer than the internodes, subcuncate 
at the base, sessile . ; 2 ‘ i - 2. S. repens. 
Erect herbs. 
Leaves homomorphous, always undivided ; seeds more 
or less radially rugose (rarely granular) on the 
faces.
