21. BISI»IZ:CVZ.ON, Linn. 



Shy^uhs or ^ref5, g-labrous. ZeflT^s.opposite; short-petioled or sessile; coriaceous, 

 orbicular ovate or lanceolate, entire, pinnate-nerved rarely 3-nerved. Flowers 

 usually in small axillary rarely terminal simple or panicled cymes or umbels. 

 Calyx-tube campanulate, glabrous; limb dilated, truncate or shortly 4-lobed. 

 Petals 4, blue or white, rarely reddish. Stamens 8, equal, filaments long ; 

 ^thers short, opening by slits in front, connective ending in a horn behind. 

 Ovary inferior, 1-celled { apex glabrous surmounted by a convex or depressed 

 u^c with 8 radiating grooves; style filiform, simple; ovules 6-12 (in M. 

 Maingayi 20 at least), whorled on a free central placenta. Berry globose or 

 ellipsoid, crowned with the calyx-margin, l-seeded. 



convolute.— Distrib. Species about 100 (but very difficult and many doubtful 

 of determination) numerous in South-East Asia and its islands ; a few extending 

 iiJto Polynesia and Australia, several in tropical Africa. 



The following is merely an artificial key to the material at Kew: the species 

 ^liich appear tolerably distinct from M, edule are taken first; and the last group 

 contains the enormous mass of specimens that appear difScult to separate from M.
