5, 3-aiigular, 3-nerved, in the middle carinate within, valvate. 

 Petals 5, unguiculate cucuUate, surrounding the stamens the same 

 in number a little longer. Germen conical, adnate at base to re- 

 ceptacle, otherwise free; style thick 3-fid; cells and ovules 3 of 

 Rhamnus. Fruit shortly ovoid, at base girt with cupule of recep- 

 tacle, indehiscent ; seeds (of Rhamnus) compressed sparsely albumi- 

 nous. — A moderate-sized tree ^ ; leaves alternate petiolate minutely 

 stipulate ovate, unequal at base, 3-nerved, serrate; flowers ^ in 

 axillary and terminal cymes, 2-cbotomously ramose ; branches of 

 inflorescence under mature fruit much thickened fleshy curved ; 

 the pedicels not perceptibly thickened. {North, India^ China, 

 Japan?) 



8. Noltia Eeichb> — Flowers polygamo-dioecious ; receptacle ob- 

 conico-turbinate, lined with a thin disk, thicker around germen 

 becoming thinner to margin. Perianth and stamens (of Rhamnus) 

 inserted beyond the disk, Germen adnate at base to receptacle, 

 otherwise free and tapering to a style 3-lobed at stigmatose dilated 

 apex ; cells and ovules 3 (of Hovenia or Rhamnus). Fruit ellipsoid 

 or shortly obovoid, finally dry, surrounded below the middle with 

 cupule of receptacle ; cocci 3, cartilaginous solute, dehiscing longi- 

 tudinally within. Seeds erect compressed thinly albuminous, 

 furnished at base with a small cupular aril. — A glabrous shrub ; 

 branches erect ; leaves alternate petiolate oblong obtuse obtusely 

 serrate penninerved ; stipules persistent tuberculiform ; flowers ^ 

 ramose axillary and terminal cymes. [South Africa.^) 



9. Colubrina L. C. Eich.'' — Flowers nearly of Noltia ; receptacle 

 shortly obconical or hemispherical. The thick disk lining the 

 receptacle annular or 5-10-lobed. Germen within adnate to re- 

 ceptacle (and disk), at free apex attenuated to a 3-fid style ; style- 

 branches obtuse at stigmatose apex. Cells and ovules of germen 3
