rarely present and then deciduous (Begoniacesie) ; cirrhi (if 

 any) axillary. Corolla (if present) not valvate. Stamens ad- 

 herent to the calyx ; anthers bilocular. Carpels 2 or more, 

 connate with each other, more or less adherent to the calyx. 

 Stigmas not sessile, or somewhat spiral (Begoniaceae). Pla- 

 centtE at the parietes, or on lamellae proceeding from the centre 

 towards the parietes. Albumen (if present) enclosing the em- 

 bryo ; radicle to the hilum. 

 Inclining to a warm habitat. 



14. PoRTUL.'\CALES. — Herbaceous or frutescent or rarely 

 arbuscular (Fouquieracese), stems round or tetragonal ; leaves 

 simple and undivided (exc. Kalanchoe, Bryophyllum) ; habit 

 succulent or nodes tumid ; stipules (exc. some Portulacacese). 

 Sexes united (exc. some Silenaceae, some Crassulaceae), not 

 affecting the floral envelopes. Sepals 2-20, more or less con- 

 nate, persistent. Petals 3 or more or rarely absent (some Al- 

 sinaceae, some Portulacaceas), alternating with the calycine divi- 

 sions when of the same number, more or less unguiculate or 

 conniving at the base, not twisted (exc. Silenaceae). Stamens 

 attached to the calyx or to its base or enclosed in a tube, not 

 fewer than the calycine divisions, not adelphous (exc. some Si- 

 lenaceae) ; anthers bilocular, dehiscing longitudinally and not 

 outwards. Carpels forming independent cells in the bud (exc. 

 some Silenaceae) ; carpels more or Jess distinct, or having the 

 styles (if any) more or less distinct (exc. Vivianieae), or having 

 the stigmas distinct, or dehiscing at the vertex. Fruit cap- 

 sular or follicular (Crassulaceae) or a berry (.-* some Silenaceae). 

 Ovules not parietal nor attached to the edges of imperfect dis- 

 sepiments, seeds not comose. Albumen farinaceous or fleshy 

 (Crassulaceae, Fouquieracea; .'' Vivianieae); ^m6rj/o not enclosed 

 in a vitelline sac, nor in the albumen except sometimes when 

 fleshy (Crassulaceae, Fouquieraceae) ; embryo curved if exterior 

 to albumen, or otherwise straight ; radicle to the hilum (exc. 

 Fouquieraceae). 



Inclining to a mild temperate habitat. 



15. Chenopodiales. — Herbaceous or frutescent or rarely 

 arboreous (Coccoloba), not lactescent ; leaves simple, undi- 

 vided (exc. some Chenopodiaceae) ; Stipules 0, or minute and
