Wile Zand. British East Africa : Jur ; at Bongo on the river Gefal, 

 Eeuglin. 



Mozamb. Blst. Zanzibar, Moscher, 



Only known to me from the original description, but is possibly a small-flowered 

 form of the variable L. arenaritis, Lindl,, as the description does not indicate any very 

 ■essential difference.

]bower Guinea. Angola : Pungo Adongo ; Cuanza River and Luxillo River, 

 3800 ft., in thickets, Welwitsch, 686 ! 



Very near L. arenarius, Lindl., but differs in its broader leaves, which appear 

 with the inflorescence, and in its usually larger flowers.

Iio-wer Guinea. Angola : Benguela, on wild fig-trees, Monteiro ! 

 Like a giant form of X. dilectus, Eeichh.f.^ the flowers being much larger, but 

 the sepals are less acuminate.
