(flower-tube, calyx-tube) adherent to the ovary. Calyx limb 

 5-toothed, ring-like, or undistinguishable. Corolla : petals 5, 

 distinct, springing from the outside o the fleshy disk, mostly 

 inflexed at the point, sometimes bifid, often unequal in size. 

 Stamens 5, alternate with the petals and emerging with them, in- 

 curved in the bud. Ovary inferior, 2-celled, composed of 2 

 coherent carpels, surmounted by a double fleshy disk or stylopod, 

 from which project 2 divergent styles ; stigmas simple ; ovules 1 

 in each cell, pendulous. Fruit consisting of 2 seed-like halves 

 (mericarps) separating at the commissure, remaining attached 

 above to a forked carpophore (fig. 388), which was previously 

 enclosed between them ; each mericarp an indehiscent 1-seeded 

 body, with the pericarp developed into longitudinal ridges (juga), 

 5 primary and sometimes 4 secondary, with intervening channels 

 (valleculce), in which often exist lines of oil-bearing tissue called
