MEMOIRS OF THE NEW YORK BOTANICAL GARDEN Wol. 8, No. 5

Desmodium tenuiflorum Micheli ex Dur. & De Wild. (Bull. Soc. Bot. Belg. 36: 

 59. 1897; 111. Fl. Congo 119, pi 60, /. 11. 1899) is said by Baker f. (Leg. Trop. 

 Afr. 448. 1929) to be a species of Dolichos near D. baumannii Harms. The illus- 

 tration rather suggests the present species. Desmodium tenuiflorum was based 

 on two sheets, both of which I have seen, thanks to the kindness and courtesy of 

 Prof. Dr. W. Robyns, Director of the Jardin Botanique de P£tat in Brussels; 

 Thonner 83 is a Desmodium which Dr. Bernice G. Schubert kindly informs me is 

 D. adscendens (Sw.) DC; while Dupuis s.n. is a species of Galactia. The name 

 Desmodium tenuiflorum thus in no way applies to Dolichos .]

 [6 Dolichos taubertii Bak. f. Leg. Trop. Afr. 445. 1929. 



Glycine maranguensis Taub. in Engl. Pflanzenw. Ost-Afr. C: 220. 1895; non Dolichos 

 maranguensis Taub. in Engl. Hochgebirgsfl. Trop. Afr. (Abh. Preuss. Akad. Wiss. 

 Berl. 1891) 27 1, 1892. 



Dolichos zanzibarensis Bak. f. Jour. Bot. 71: 342. 1933. 



I have seen the type-number of this species (Volkens 2121, Kilimanjaro) in 

 the British Museum Herbarium. Further good material, particularly of the fruit, is 

 much wanted. It is found in Uganda (Maitland 896, 995), Kenya (Miss E. R. Napier 

 1090, van Someren 289), Tanganyika Territory (Haarer 520, Burtt 2774, Rounce 

 53, Emson 368, Bally 2217), and the Transvaal (Rogers 20965). 



Dolichos zanzibarensis Bak. f., of which I have examined the type at the Brit- 

 ish Museum, I think is only a large-leaved form of D. taubertii and not a valid 

 species.] 



7. Dolichos oliganthus Brenan, sp. nov. 



D. brevicauli Bak. ut videtur proxima, calycis dentibus brevioribus triangu- 

 laribus differt; a D. rupestri Welw. ex Bak. leguminibus angustioribus 5 mm. tan- 

 tum latis, stipellis brevioribus, foliolis apice non rotundatis differt; a D. chrys- 

 antho A. Chev. habitu, calyce, leguminibus longioribus longe distat. 



Herba perennis, caules herbaceos ut videtur suberectos turn reptantes et usque 

 ad 45 cm. longos 2 mm. crassos teretes pilis leviter deflexis vel raro appressis 

 breviter sed dense pubescentes e caudice emittens. Folia trifoliolata; petioli 

 (1.5-)3-6 cm. longi, tenues, pubescentes, supra canalicular^; stipulae ovatae 

 usque oblongo-lanceolatae, costatae, acutae, 4-10 mm. longae, 2-4 mm. latae; 

 foliola basi obtusa, apice obtusa vel subacuta, utrinque appresse pubescentia, 

 costa nervisque lateralibus utrinque 5-10 supra inconspicuis vel prominulis sub- 

 tus ut rete venularum prominulis vel prominentibus; foliolum terminate oblongum 

 vel ellipticum, 3-8 cm. longum 0.9-3 cm. latum; foliola lateralia similia sed 

 margine antico gibbosa, paulo latiora, 1-3 cm. lata; stipellae 2-3(-5) mm. longae, 

 lineari-lanceolatae. Inflorescentiae axillares, sessiles vel subsessiles, 1-3* 

 florae; pedicelli 3-5 mm. longi, pubescentes; bracteolae 2-3*5 mm. longae, lan- 

 ceolatae, basi calycis positae. Flores quoad colorem collectoribus varie de- 

 scripti : virides, viridi-lutei, pallide lutei, albi. Calycis tubus 3.5-4 mm. longus, 

 obconicus, pubescens; dentes omnes pubescentes acuti; dens infimus anguste 

 triangularis, 2.5-4 mm. longus, basi 1.25 mm. latus, paulum sursum curvatus; 

 dentes 2 laterales anguste triangulares, 2-3 mm. longi, basi 1.5 mm. lati; dentes 

 2 superiores connatae, 2.5-4 mm. longae, basi 3.5 mm. latae, deltoideae. Corolla: 

 vexillum obovato-orbiculare, apice emarginatum, 12-17 mm. longum, 9-15 mm.
