REVISION OF THE AFRICAN SPECIES OF ERIOSEMA. 145 



This plant is probably identical with HlujncJwHia paoraJuiiles DC. 

 Prod. ii. 389, in which case it will have to take the name Kriosema 

 l^soraleoides Don, Gen. Sijst. ii. 348. 



Stems erect or suberect, 4-5 ft. high, branched, branches softly 

 pubescent, somewhat angular. Stipules minute, lanceolate. Petioles 

 ^-\ in. long. Leaflets, central one narrow-oblong or oblanceolate, 

 2-3 in. long, blunt or acute, subcoriaceous, upper surface glabrous 

 or nearly so, under side covered with a soft grey pubescence, 

 petiolule about as long as petiole. Flowers not nearly so densely 

 racemose as in E. parn'jlnnun ; racemes 2-4 in. long. Pedicels 

 very short. Calyx about 2 lines long ; sepals ovate, acute, or sub- 

 deltoid, nearly half the length of the calyx. Flowers J-f in. long 

 to even ^ in. Legume ovate, oblong, ^ in. or rather more long by 

 rather less broad, covered with white or brownish white hairs, 

 obliquely apiculate. 



I have adopted the name used in the Tropical African Flora for 

 this plant, although this is posterior to E. polystacltynm, as the use of 

 the latter name would mean a change of name in an allied species. 



** Calyx longior, ssepissime 2-|-4 lin. longus. 



14. E. Buchanani, n.sp. Caulis erectus dense ferrugineo- 

 pubescens ad basin lignosus, foliis trifoliolatis, foliolis ovatis vel 

 ovato-oblongis, acutis basi rotundatis, lateralibus injequilateralibus, 

 junioribus pr^cipue subtus veniisque ferrugineo-pubescentibus, 

 lloribus dense racemosis, racemis axillaribus et terminalibus, 

 pedunculis ferrugineo-pubescentibus, lloribus subdepressis, calyce 

 externe ferrugineo-pubescente laciniis lanceolatis acutis, petalis 

 calyce longioribus, leguminibus ferrugineo-villosis 2-spermis, se- 

 minibus nigrescentibus. 



Hab. Top of Mt. Zomba, Buchanan, No. 214 ! Shire High- 

 lands, Scott Elliot, No. 8611 ! 



Stem erect, about Ii ft. high, possibly more, densely clothed 

 with ferruginous pubescence. Leaves trifoliolate ; leaflets ovate or 

 ovate-oblong, acute, base rounded or cuneate, not so long as those 

 of E. pohjstaclujwn ; lateral leaflets unequal-sided, pubescent on 

 both surfaces, young leaves and especially the veins underneath 

 ferruginous, pubescent. Flowers in dense terminal and axillary 

 racemes, which are 1^-2 in. long; peduncles covered with dense 

 ferruginous pubescence. Flowers somewhat depressed ; calyx 

 about 3 lines long, externally covered with ferruginous pubescence ; 

 sepals lanceolate, acute ; petals longer than the calyx, about ^ in. 

 Legume ^-^ in. long, apiculate when young, ferruginous, villose, 

 2-seeded ; seeds black. 



Allied to E. poli/stachi/nm. 



The leaflets are more ovate and shorter ; and the peduncles 

 clothed with a more dense ferruginous tomentum, and the sepals 

 and petals rather longer. 



There is anotlier plant, collected by Buchanan in the Shire 

 Highlands, No. 339 ! which is closely allied to the above. The 

 stem, however, is higher (G ft.), the leaflets more pointed, and the 

 calyx-teeth are triangular and shorter. 



Buchanan, No. 117 (1879), is also allied.
