21'i NATURAL HISTORY OF PLANTS. 



etc., of Sorocea. — Shrubs or trees (?) ; habit and leaves of Sorocea •} 

 limb entire, widely or coarsely spinoso-dentate, penninerved venose ; 

 costa and primary nerves anastomose at margin and somewhat -pro- 

 minent beneath ; but flowers of both sexes inserted singly at amenti- 

 form margins of elongated receptacle and there glomerate sessile ; 

 both faces naked sulciform. [Trop. and subtrop. South America.^) 



56? Sahagunia Liebm.^ — Plowers dioecious; males densely 

 congregated on spikelike branched receptacle (naked along longi- 

 tudinal furrow), destitute of perianth and consisting of very crowded 

 stamens, intermixed with cuneate cucullate-capitate bracts ; filaments 

 subulate ; anthers subbasifixed ; cells sub-2-dymous subopposite, 

 rimose. Female flower and fruit . . . ? — A moderate- sized tree ; 

 leaves alternate, shortly petiolate, oblong penninerved ; stipules 2, 

 convolute, deciduous ; male inflorescences racemose or fasciculate on 

 naked or more rarely foliate branchlet.* {Mexico,^ Brazil ?) 



57. Pouroxuna Aubl.^ — Flowers dioecious ; male calyx 4-merous ; 

 folioles free or more or less highly connate, sometimes almost to 

 apex. Stamens 4, oppositisepalous ; filaments free or connate at 

 base, straight or slightly incurved ; anthers short, introrsely riraose. 

 Calyx of female flower gamophyllous, ovoidly or conically tubular, 

 thickened at base to a more or less prominent oupule, entire at apex 

 and perforated at very small mouth. Germen sessile free, 1-locular, 

 conical and attenuate above to style with more or less stigmatose 

 apex, sometimes very disooidly peltate, entire or unequally lobed, 

 very papillose. Ovule in cell 1, sessile, inserted laterally to linear 

 parietal hilum hemitropous ; chalaza inferior, sub-contiguous to base 

 of cell ; mioropyle free extrorsely superior. Fruit enclosed by fleshy 

 culyx, ligneo-crustaceous, finally 2-valved. Seed sometimes laterally 

 adnate to pericarp by linear hUura, ovoid ; testa membranous ; coty- 



' Of which perhaps better a section ? A opposite surfaces floriferous, i.e. hearing numer- 



genus hitherto admitted as a mean between ous stamens without perianth. In other respects

flowers.) hitherto supplied (as demanded by Bureau in
