Dr. Cronquist says also that T. atroviolacea Bak. f. [ex De Wild. Bull. Soc. 

 Bot. Beige 57(2): 115. 1925] is not specifically separable. 



Sesbania sesban (L.) Merr. Philipp. Jour. Sci. Bot. 7: 235. 1912. 

 Aes chynomene sesban L. Sp. PI. 714. 1753. 



Sesbania aegyptiaca ["Sesban aegyptiacus"] Poir. in Lam. Encyc. 7:128. 1806; Phil- 

 lips & Hutch. Bothalia I: 44. 1921; Bak. f. Leg. Trop. Afr. 259- 1929. 



Kota-kota District: Benga, west shore of Lake Nyasa, plentiful on sandy lake- 

 shores, shrub 2-3 m. high, flowers yellow mottled with purple, fruit pendent, 470 

 m., Sept. 2, 1946, 17482. Chikwawa District: Lower Mwanza River, plentiful on 

 sandy beaches, about 2 m. high, flowers yellow, fruit immature, 180 m., Oct. 6, 

 1946, 17995*. Old World tropics; also in central America and the West Indies, 

 where it is probably introduced. 



Herminiera elaphroxylon Guill. & Perr. in Guill., Perr. & Rich. Fl. Senegamb. 

 Tent. 201. pi ft. 1832-1833- 

 Aeschynomene elaphroxylon (Guill. & Perr.) Taub. in Engl. & Prantl, Nat. Pflanzenf. 

 3 3 : 3 2 0. /. 124. 1894; Bak. f. Leg. Trop. Afr. 289. 1929. 



Kota-kota District: Benga, west shore of Lake Nyasa, plentiful in marginal 

 sandy shallows of lake and on beach, tree or shrub 5-7 m. high, flowers orange- 

 yellow, showy, pods viscid, hairy, 470 m., Sept. 2, 1946, 17494. Native name, 

 bingwi. Widespread in tropical Africa and Madagascar. 



This is the ambatch of the Nile sudd. 



Aeschynomene ? stolzii Harms, Bot. Jahrb. 54: 384. 1917; Bak. f. Leg. Trop. Afr. 

 290. 1929. 



North Nyasa District: Nyika Plateau, common locally on forest edges, shrub 

 1-1.5 m. high, somewhat viscid, flowers orange-yellow, standard streaked with 

 red, 2440 m., Aug. 11, 1946, 17170. 



No authentic specimens of Aeschynomene stolzii from Tanganyika Territory 

 are available to me; Brass 17170 apparently differs in not being prostrate or suf- 

 fruticose. However I believe that Mr. Brass* specimen is conspecific with Green- 

 way 3568 from Rungwe, southwestern Tanganyika Territory, which is described as 

 being a perennial mat-herb. If Brass 17170 is A. stolzii, it is new to Nyasaland. 



Aeschynomene megalophylla Harms, Repert. Sp. Nov. 8: 355. 1910; Bak. f. Leg. 

 Trop. Afr. 291. 1929. 

 Mlanje District: Mlanje Mountain; Luchenya Plateau, abundant in forest re- 

 growths, also found on rocky grass slopes near forest, tree or shrub up to 5-6 m. 

 high and 25 cm. in diameter at breast-height, flowers as a shrub, but attains tree 

 size, hairs viscid, petals golden-yellow, sepals red, 1900 m., July 7, 1946, 16717. 

 Nyasaland, and a form with glabrous leaves in S. Rhodesia. 



Aeschynomene ? heurckeana Bak. Jour. Linn. Soc. Bot. 20: 130. 1883. 



Aeschynomene dissitiflora Bak. Kew Bull. 1897: 259. 1897; Bak. f. Leg. Trop. Afr. 

 293. 1929. 



North Nyasa District: Nyika Plateau, prostrate on open grassy bank of a 

 stream, herb, flowers orange, 2200 m., Aug. 11, 1946, 17154. 



I do not consider that Aeschynomene dissitiflora can be specifically separated 

 from A. heurckeana, a species hitherto known only from Madagascar. Certain 

 specimens at Kew must certainly be referred to A. heurckeana, e.g. Whyte s.n. 

 (Nyasaland, Masuku Plateau, 1980-2130 m., July 1896), Hutchinson & Gillett 3730 

 (N. Rhodesia, Lukulu River, July 16, 1930) and Schliehen 1193 (Tanganyika Ter- 

 ritory, Upper Ruhudje, Lupembe area, N. of the river, frequent in riparian bush, 

 1600 m.). .
