.jand form it is much like M. Lesliei, iS. E. Br., but the much 

 .^deeper fissure separating the tips of the leaves and the peculiar 

 .tawny colour of their truncate tips, marked with small round dull 

 dark green dots, readily distinguishes it from that species, which 

 also comes from a far distant locality in the Transvaal.

Metaporana, N. E. Brown [Convolvulaceae-Convolvuleael ; 



genus novum affine Poranae, Burm., sed calycis lobis immutatis, 

 corollae lobis patentissimis et capsula e calyce longe exserta differt. 



Sepala aequalia, fructu immutata. 'Corolla ultra medium 

 5-loba_; tubus subcylindricus calyce aequilongus; lobi induplicato- 

 valvati, patentissimi. Stamina 5, exserta, tubo corollae affixa ;

 Semina subangulato-ellipsoidea, glabra. — Frnfices volubiles. 

 Folia alterna, ovata vel oblonga. Flores parvi, in cymas vel 

 paniculas axillares vel terminales dispositi. 



Of the two species belonging to this genus, one is new and the 

 other has been placed in the genus Parana, from which the un- 

 changed calyx and much exerted capsule at once distinguish it. 

 The habit of the plants and texture of the calyx and corolla are 

 also different from that of Porana. Both are" evidentlv nearlv 

 related, but may be readily distinguished by the foUowinir 

 characters : 



Leaves ovate, acute, acuminate or obtuse, with 



«:> 



petioles 0-5-2 cm. long; styles 2, with very 



large stigmas ...
