MEMOIRS OF THE NEW YORK BOTANICAL GARDEN

whereas those of type R. clivorum are uniformly dark reddish-brown. Two other 

 specimens in Herb. Kew. (Eyles 3617, S. Rhodesia, and Hutchinson & Gillett 

 4369, N. Transvaal) are intermediate in appearance between the type and var. 

 caudata. 



Rhynchosia clivorum S. Moore var. fulvida Meikle, var. nov. 



A typo differt caulibus, stipulis, foliis et inflorescentiis breviter fulvo-villo° 

 sis; foliis ellipticis vel ovato-lanceolatis, valde reticularis; racemis congestis 

 circiter 3.0 cm. longis, pedunculis brevibus; vexillum eleganter (in siccis) pur- 

 pure o-stria turn. 



North Nyasa District: Nyika Plateau, shrubby borders of montane forest, shrub 

 2 m. high, flowers yellow, 2300 m., Aug. 13, 1946, 17205 (TYPUS varietatis). 



This variety is probably identical with Rhynchosia oreophila Harms, described 

 from material collected by Stolz (no. 2232) in the Kinga Mountains, S. Tanganyika. 

 The type of this species is unfortunately not available for comparison, but the 

 characters used in the original description to distinguish it from Flemingia macro- 

 calyx Baker f. (=R. clivorum S. Moore) are, to my mind, scarcely sufficient to 

 give it specific rank. The size and shape of leaves, length of racemes and size 

 of individual flowers are all subject to considerable variation in R. clivorum, as 

 in other species of Rhynchosia. 



Rhynchosia insignis (O. Hoffm.) R. E. Fries, Schwed. Rhodesia-Kongo-Exped. 

 1911-1912 1: 95. 1914; Bak. f. Leg. Trop. Afr. 486. 1929. 

 Eriosema insigne O. Hoffm. Linnaea 43: 128. 1881. 



Rhynchosia subaphylla Bak. f. Jour. Bot. 66(suppl. 1): 121. 1928; Leg. Trop. Afr. 

 486. 1929. 



Kota-kota District: Nchisi, Brachystegia woodlands, shrub 20-30 cm. high, 

 young shoots flowering a month after burning of the grass, flowers yellow, 1350 

 m., Sept. 8, 1946, 17572;* Chenga Hill, sporadic in low open Brachystegia wood- 

 land, perennial herb to 30 cm. high, young shoots flowering after burning of the 

 grass, wings yellow, standard and keel brown, 1600 m., Sept. 9, 1946, 17594. 

 Recorded from Nyasaland, S. Rhodesia, N. Rhodesia, and Angola, apparently not 

 uncommon in this area. 



I have no hesitation in uniting Rhynchosia subaphylla Bak. f. with R. insignis 

 (O. Hoffm.) R. E. Fries; the latter species frequently produces shoots with simple 

 leaves, and the young leaves are just as silvery-tomentose below as those of R. 

 subaphylla. The types of both species are from Malange, Angola. 



Eriosema psoraleoides 25 (Lam.) G. Don, Gen. Syst. 2: 348. 1832.

Eriosema cajanoides (Guill. & Perr.) Hook. f. in Hook. Niger Fl. 314. 1849. 



Kota-kota District: Chia area, occasional on grassy alluvial flats, shrub about 

 1 m. high, leaves greyish below, flowers yellow, 480 m., Sept. 7, 1946, 17560. 

 Widely spread through tropical Africa, and in Madagascar. 



Eriosema montanum Bak. f. Jour. Bot. 33: 142. 1895.

 grasslands, shrub 1 m. high, flowers yellow, 1900 m., Aug. 20, 1946, 17365. 

 Kenya and Uganda to Nyasaland and N. Rhodesia. 



Eriosema affine De Wild. Ann. Mus. Congo. IV. 1: 200. 1903.

 80-100 cm. high, leaves grey below, stems several, erect, little branched, flowers
