Papaw. (Asiminier.) 



Calyx of 3 ovate sepals, much smaller than the corolla, 

 valvate in aestivation, deciduous. Petals 6, in two series, 

 each set rather imbricated than truly valvate in asstivation 

 (at least the margins, especially of the exterior, overlap more 

 or less), hypogynous ; the three exterior widely spreading ; 

 the three inner (opposite the sepals) much smaller and nearly 

 erect ; all rather fleshy, veiny and rugulose, roundish, ovate, 

 or obovate-oblong, closely sessile, enlarging considerably 

 after expansion, deciduous. Stamens innumerable, densely 

 packed together and covering the spheroidal receptacle : 

 filaments extremely short, thick : anthers extrorsely ad- 

 nate to the fleshy connective, which is much longer than 

 the proper filament, and is terminated by a broad and dilat- 

 ed-truncate glandular tip ; tbe cells oblong or linear, sepa- 

 rate, opening longitudinally. Pollen of spheroidal grains 

 lightly united in fours. Pistils 3 to 15, sessile on the 

 summit of the receptacle, protruding from the centre of the 

 globose mass of stamens, distinct : ovary one-celled : style 

 short or none : stigma unilateral at the tip. Ovules 4 to 20, 

 horizontal in two series on the ventral suture, anatropous; 

 the raphes towards the suture.
