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

 No. 5533. 



Var. caerulea. 



About 9 in. high ; flowers deep blue. 



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

 of the presidium, sparingly ; fl. Dec. 185G. Xo. 5521. 



Var. albiflora. 



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

 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 diifers and the corolla is 

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

 apparently of a different species.
