Calyx naked (destitute of an involucel), or very rarely 

 subtended by one or three bractlets, usually angled in the 

 bud, five-cleft, the segments valvate in sestivation. Petals 

 5, usually oblique, convolute in asstivation, hypogynous, 

 deciduous. Stamens numerous, monadelphous in a simple 

 hypogynous column, the dilated base of which is united 

 with the claws of the petals : filaments all arising from the 

 summit of the column : anthers reniform, one-celled, open- 

 ing by a semicircular line, two-valved. Ovaries 5 to 15, 

 united around a central receptacle : styles as many as the 

 ovaries, united below : stigmas terminal, capitate. Ovule 

 solitary in each carpel, borne on the inner angle near the 

 summit of the cell, nearly anatropous, resupinate-pendulous, 

 the raphe therefore dorsal or external, and the micropyle 

 ascending next the axis. 



Fruit of 5 to 15 erect and straight or incurved one- 

 seeded (beaked or bcakless) carpels, which arc more or less 

 included in the persistent calyx, indehiscent or usually two- 

 valved at the apex, and tardily separate at maturity from the 

 central axis. Seed suspended, often somewhat trigonous, or 

 with a sinus at the hilum which is directed to the summit
