ellipsoideum, 6 mm. longum, 3.5 mm. latum, nigrescens, lit videtur unilateraliter 

 sulcatum necnon etiam linea angustissima circumcinctum. 



Nyasaland, without more precise locality, 1891, /• Buchanan 975 (TYPUS in 

 Herb. Kew, o* and ¥ flowers and fruits), 977 (Herb. Kew., S buds and flowers). 

 Mlanje District: Likubula Gorge, common on floodswept rocky banks of river, tree 

 or shrub 2-3 m. high, branches horizontal, fruit orange-yellow, 840 m., June 20, 

 1946, 16385. 



This new species is a member of a small group including D. natalensis, D. 

 dawei, and D. nummularia Brenan, which would formerly have been all put under 

 Maba; of these D. natalensis is apparently the nearest relative. 



0. nyasae is distinct from the other three by its leaf-shape alone, which seems 

 unusually constant in these species: the lanceolate leaves of 0. nyasae contrast- 

 ing with the elliptic leaves of 0. natalensis and D. dawei and the ovate to orbic- 

 ular leaves of 0. nummularia. In addition the indumentum of the young branchlets 

 is important: D. natalensis, D. dawei, and D. nummularia have a very short patent 

 puberulence among which longer usually ascending bristly hairs may or may not 

 be mixed; the longer bristly hairs are or are not present iri D. nyasae but the 

 "understory" of puberulence is absent on all the specimens I have seen. 



D. nyasae is also remarkable in that its cf inflorescences are reduced to a 

 single subsessile or very shortly stalked flower; in D, nummularia and 0. dawei 

 the 0* inflorescences are 2-4-flowered. Unfortunately the S inflorescence of D. 

 natalensis has yet to be collected and described.

This seems near to S. goetzeana Gilg, Dot. Jahrb. 28: 450. pi. 8 (1900); 30: 

 70, 72 (1901); Lingelsheim, Pflanzenreich 72 (4 243 ): 102 (1920); which, however, 

 has a non-alate rhachis to the leaves; and near also to S. mazoensis So Moore, 

 Jour. Bot. 45: 48 (1907); Lingelsheim, Pflanzenreich 72 (4 243 ): 107 (1920); which 

 is pubescent not glabrous. The taxonomy in this genus is difficult, and further 

 ample and carefully selected material is wanted so that we can work out how 

 vvide a variation exists under the various species.
