PLATE 349. 
Ruyncwosia mMemnonia, DC. (FI. Cap. Vol. IL, p. 258). 
Natural Order, Lecuminosz. 
A usually erect but sometimes prostrate plant, canescent-tomentose or silky in 
all parts, and bearing yellow flowers. Stems and branches more or less striate or 
angular, erect (in our specimens), 1 to 2 feet high. Leaves trifoliate, stipulate, 
petiolate, common petiole, $ to 13 inch long; stipules ovate, acuminate, deciduous, 
silky outside, brown within, 2 lines long, 1 line wide at base. Leaflets obovate, 
sub-rotund, oblong or sub-rhomboid, entire, veins prominent beneath, petioles of 
lateral leaflets 1 to 2 lines long, stipella capillary, ] line long; petiolule of terminal 
leaflet 3 to 4 lines long, stipella like the lateral ones, but 1 line below base of leaflet ; 
lateral leaflets 8 lines to 1 inch long, 6 to 8 lines wide. Infloresence racemose, 
axillary, floriferous tor about half its length or more. Peduncles (in our speci- 
mens) 2 to 5 inches long, laxly many flowered. Calyx gamosepalous, 5-fid, tube 
campanulate, oblique, lowest lobe longest; four upper connate in pairs. Vexillum, 
broadly obovate, auricled at base, auricles a little infllexed; alae narrow, auricled 
at base, equalling vexillum ; carina oblong, broader than alae, equalling them in 
length; incurved. Stamens, diadelphous-9-1, curved, free filament geniculate at 
base. Ovary, 2-ovuled, silky. Style curved and swollen at the curve. Stigma 
capitate. Legume a little curved, 9 to 10 inches long, 2 to 3 lines wide, densely 
white tomentose. 
Habitat: Natau: Umsundusi, Zululand, 0-1000 feet alt, April, Wood, No. 
3954; N’Tondweni, Zululand, J. Wylie (Govt. Herb. No. 3935); N’Tondweni, 
Zululand, December, Wylie (Woud, No. 9197). 
_ One species only of this genus has been already figured in this work, viz., 
Rhynchosia orthodanum, Vol. III., p. 220, and in the note it was stated that it and 
lt. Woodit were the only “species of the genus known to us in Natal having a 
quite erect habit.” 2. Memnonia, however, though usually erect, is occasionally 
prostrate, and specimens of the prostrate form were gathered amongst the erect 
ones. Whether the plant becomes prostrate in age or not is as yet uncertain. 
The localities given above are so far as known at present the only Natal localities 
for it.
