HuiLLA. — In rocky mountainous places from Lopollo towards J^u ; 

 fl. and fr. end of April 1860. No. 3569. In rather dry stony hilly 

 places between Mumpulla and Lopollo ; fl. April and fr. end of May 

 1860. No. 3570. 



Eelated to 0. tripUnervia DC. ; it differs by a more divaricately 

 branched inflorescence, etc.

 MossAMEDES. — A fleshy, rigid shrub, 1 to 2 ft. high, with a yellow 



resin ; ramification sometimes pseudo-verticillate, in other cases 

 forked ; flowers apparently yellow. In dry hilly places about the 

 Giraul, plentiful ; past flowering nearly all the flowers having fallen,

The condition of the specimens does not enable me positively to 

 identify them, but they agree with this species, except in the shorter 

 peduncles, which are about 2 in. long and equal or scarcely exceed the 

 foliage, and in this respect they resemble 0. osteospermoides DC. ; 

 from this latter, however, they differ by the involucral scales being 

 only 5, instead of 8 ; possibly they belong to an undescribed species.
