6. BREWERIA, E. Br. 



(Prevostea, C/iois. j Seddera, Sochst. and Steud. ; Stylisma, Null.) 



Corolla campanulate, angular or shortly and Iroatlly 5-lobed, folded in 

 ™ bud. Ovary 2-celled, with 2 ovules in each cell. Style bifid or di- 

 ^'led to the base, with a capitate stigma to each branch. Fruit a dry cap- 

 siile.— Herbs or undershrubs, with ei-ect prostrate trailing or twining stems, 

 often tomentose or silky. Leaves usually entire. Flowers axillary, solitary 

 or rarely 2 or 3 together in the Australian species, the upper ones often 

 forming a leafy spike, or in extra-Australian species the peduncles often 

 several-flowered. 



Jl^e genus, as at present constituted, iucludes several species from tropical Asia, Africa 

 »M America, but the Australian ones appear to be all endemic. The habit is often that of 

 «»ne species of Convohulus, hut the style is very different. A. Gray (Proc. Amcr Acad. 

 \ 336), relying onlv upon the characters given by R. Brown and by Choisy, thought that 

 ;»^"^ma could not' be separated from Bonamia, Thou.; the study however of rhouars 

 ? tailed descriptioa and figure (in the absence of antheutic specimens) shows that he latter 

 *^ rieither the inflorescence nor probably the estivation of the corolla nor the trmt of ton- 

 ^"'^facecB, but appears to be more closely allied to Ehretla and Cordia,y^^th the sty c of 

 former and the embryo of the latter. A. Gray appears, however, to t'e f te "ght in 

 "f'ng Sl^ii,,„^^ Nutt., with Jirewerla; nor can I distinguish the African ^.^'^t-r^, Hochst 

 J>f jet the tropical American Dufourea, H. B. and K., or Prevostea, Chois., for the sole 

 Jhdracter given for the latter, the enlarged outer sepals, occurs m a very marked way in B,
