 Stipules linear-subulate, 2-3 mm. long- ; leaves numerous, much 

 longer than the internodes, the rachises 3-5 cm. long, shallowly 

 sulcate on the upper side, densely brown-puberulent ; leaflets 9-13, 

 the lateral ones opposite, oval or oval-oblong, 9-20 mm. long, 4-8 

 mm. wide, rounded or very obtuse at each end, mucronate at the 

 apex, rather firm, grayish green and strigillose on the upper surface, 

 pale beneath and more densely strigillose ; flowers partly in dense 

 axillary racemes up to 10 cm. long, on peduncles 3 cm. long" or 

 shorter, but also in terminal racemes, these sometimes corymbose, 

 the racemes very dense, many-flowered, the rachis densely brown- 

 puberulent ; bracts subulate, equaling or shorter than the calyx ; 

 pedicels 1-2 mm. long; calyx 2 mm. long, densely brown-puberulent, 

 the lobes about as long as the tube ; banner 5-7 mm. long, densely 

 brown-sericeous outside ; legumes deflexed, straight, subterete,

Type in the U. S. National Herbarium, no. 631040, collected in 

 the vicinity of Nairobi, British East Africa, altitude about 2,000 

 meters, August 16 to September 3, 1909. by E. A. Mearns (no. 

 1004). Alearns's no. 958 from the same locality is this species, as 

 well as no. 208, from Juja Farm, near Nairobi. 



The proposed species is an ally of Ind'gofera macrophylla Schum., 

 which differs in its large leaflets, long slender racemes, and glabrous 

 legumes. It may be that /. mearnsii is the same as /. oliveri 

 Schweinf.^ That name was applied to a plant collected in the 

 Masai Highlands near N'doro by Von Hohnel, but no description 

 has ever been published.
