gynous disk, often with inflexed points (figs. 282, 613). Stamens 5, 

 alternate with the petals, incurved in {estivation (figs. 613, 614), 

 Ovary inferior, 2-celled, crowned with a double disk or stylopod (fig. 

 614 g e]\ ovules solitary, pendulous; styles 2, distinct (fig. 454 s s) ; 

 stigmas simple. Fruit (figs. 615, 616) a cremocarp (^f 543), consist- 

 ing of two achfenia (mericarps or hemicarps), which adhere by their 



face (commissure) to a common axis (carpophore), from which they 

 separate, and are suspended when ripe (fig. 454 a) ; each mericarp is 

 traversed by five primary longitudinal ridges (jugas), and often by four 

 alternating secondary ones, the ridges being separated by channels 

 (vallecula;). In the substance of the pericarp there are frequently vitta? 

 containing oil, which are usually opposite the channels. Seeds pendulous 

 (fig. 616 y), usually adherent to the pericarp, rarely loose; embryo 

 minute, at the base of abundant horny albumen (fig. 616 e); radicle 

 pointing to the hiluni. Herbaceous plants, often with hollow and fur- 

 rowed stems, with alternate, rarely opposite, variously divided, sheath-
