PEARSONIA, A NEW GENUS OF LEGUMINOS^ 357 



elliptic acuminate-aristate leaflets, which are subglabrous on 

 the upper, and conspicuously netted on the lower surface ; 

 leaflets -15 mm. long, -5 mm. broad. Floioers solitary or 

 in racemes ; racemes occasionally secund, 2-10-flowered ; bracts 

 lanceolate-subulate, -5 mm. long. Flowers -15 mm. long. 

 Legumes oblong, acute, compressed, straight, 25 mm. long, 5 mm, 

 broad, fulvously hirsute. 



The species extends into South-eastern Ehodesia and Gazaland, 

 where it is represented by var. gazensis, which is distinguished by 

 its more robust habit. Wilms's No. 263 is doubtful, as it possesses 

 neither flowers nor fruit. 



7. P. FiLiFOLiA, comb. nov. L. filifolia Bolus in Journ. Linn. 

 Soc. Bot. XXV. 158 (1889). 



A species having much in common with P. aristata, but with 

 subangular, less hirsute twigs, longer filiform or oblanceolate- 

 cuneate, acute or obtuse leaflets, longer, laxer racemes and less 

 hairy legumes. Leaflets 20-45 mm. long, 2-5 mm. broad. 

 Eacemes 4-7 cm. long, laxly 4-14-flowered. Flowers 10-12 mm. 

 long, shortly pedicellate; bracts subulate, as long as the calyx-tube.

 minal leaflets 5 mm. long, 2-5 mm. broad, the lateral slightly
