 glands, one lobe rotund and veiny, the other lobes lanceolate and 

 short; corolla thin, glabrous, black -punctate, bent in a sigmoid 

 manner ; stamens 4, didynamous, all fertile ; filaments apparently

PuNGO Andongo. — In Mata de Pungo ; fl. and fr. April 1857. 

 No. 5533. 



Var. cserulea. 



About 9 in. high ; flowers deep blue. 



Pungo Andongo. — By streams in the more elevated rocky parts 

 of the prsesidium, sparingly ; fl. Dec. 1856. No. 5521. 



Var. albiflora. 



A slender limp herb, 1 to ^ ft. high ; flowers w^hite. 



Pungo Andongo. — In sandy places between Luxillo and Cazella, in 

 tall grass ; fl. beginning of May 1857. No. 5586 partly. 



The last variety bears a close resemblance to P. parvus Oliv., a 

 Somali-land species, but the calyx slightly differs and the corolla is 

 smaller in the latter. Part of No. 5586 consists of flowerless specimens- 

 apparently of a different species.
