Vexillum 1'2 cm. long, 1 cm. broad, suborbicular, densely villous 

 without, with a short concave claw 3 mm. long bent at right angles 

 to the limb ; alae 1'2 cm. long, 4 mm. broad below, ovate-lanceolate, 

 subobtuse, glabrous, with transverse ridges on the lower half and a 

 linear claw 4 mm. long ; carina 1'4 cm. long, 5 mm. broad, almost 

 plano-convex in outline, obtuse, with a linear claw 4 mm. long. Ovary 

 1 cm. long, linear in outline, densely villous ; style 7 mm. long, 

 curved; stigma minute, capitate. Fruit 24 cm. long, 3 - 5 mm. broad, 

 compressed, beaked, villous. 



Closely allied to L. Wyliei, Wood, from which it differs in the less 

 shrubby habit and in the manner in which the lateral calyx-lobes are 

 joined. 



forma sericea. 



Ramuli, folia vexillumque sericeo-pubescentes non villosi. 



In this form of the species the branchlets, leaves, and vexillum are 

 silky-pubescent, not villous, as in the type. 



Slopes of Litsoeneug Mountain, Botsabelo, near Maseru. February. 

 Flowers cream and blue. A. Dieterlen, 1020. 



var. robusta, Phillips, var. nov. 



A typo habitis robustoribus et ramis rigidis lignosis divaricatis 

 cliff ert. 



This is distinguished, from the type by the more robust habit, and 

 by having stiff woody divaricate branches, otherwise similar to the 

 type. 



Slopes of the Mont-aux-Sources, 8000 ft., January, Flanagan, 2095. 



forma sericea. 



Folia sericeo-pubescentia non dense pubescentia. 



Similar to var. robusta, but the leaves are finely silky-pubescent, not 

 densely pubescent. 



Natal, Drakensberg, Polela, 6-7000 ft., February. Flowers light- 

 blue, Evans, 634. 



The above separation of the species must be regarded as provisional 

 until more material can be examined. The material at my disposal 

 certainly showed four distinct forms, which could be easily separated 

 by a superficial examination. Evans 634 and Flanagan 2095 differ 

 from both of Madame Dieterlen's specimens by their more robust 

 habit. The branches are from 4-5 mm. in diameter, whereas in the 

 Basutoland specimens they are only 2 mm. in diameter. Then again 

 Evans 634 and Diderlen 1020 agree in having a silky indumentum, 

 while Flanagan 2095 and Dieterlen 353 have a densely pubescent,
