solitary subsessile piriform, adnate to middle of germen in central 

 cavity, and finally covering fruit, externally above the middle sur- 

 rounded by alternate imbricate bracts. [Tropical Asia and Oceania}) 



41. Pseudolmedia Tréc. 2 — Flowers monoecious or dioecious ; 

 males composed of co stamens inserted in an orbicular discoid or 

 rather concave involucrate receptacle ; filaments free ; anthers 

 oblong, sometimes penicillate at apex, subsagittate at base. Female 

 flowers solitary central in polyphyllous involucre ; calyx tubular or 

 ovoid, perforated only at apex and there entire or shortly denticu- 

 late. Germen in part inferior and adnate to a greater or less height 

 to the calyx, free at conical apex ; style lateral erect enclosed or 

 passing through tbe mouth of the calyx, entire or bifid ; legs 

 stigmatose. Ovule 1, inserted under apex of cell, descending, ana- 

 tropous ; micropyle extrorsely superior ; or more rarely inserted 

 laterally to linear hilum ; micropyle superior. 3 Fruit enclosed by 

 calyx, indéhiscent ; seed descending or long adnate laterally to 

 pericarp ; cotyledons of fleshy embryo very unequal ; one very 

 small ; radicle short superior.— Trees or shrubs, often pubescent or 

 hirsute ; leaves petiolate or subsessile distichous ; stipules lateral 

 conniveutly imbricate amplexicaul ; scar linear transverse; in- 

 florescence axillary, solitary or fasciculate ; bracts of male involucre 



co, imbricate, subspathulate unequal ; the interior longer and 

 narrower ; stamens intermixed with bracts sometimes setaceous 

 hirsute; bracts of female involucre same in form or shorter. (Trop, 

 central and south America.*) 



42. Castilloa Cervant. 5 — Flowers monoecious (nearly of Pseudol- 

 media). collected in distinct subplane or induplicate reniform recep- 

 tacles, involucrate with crowded imbricate bracts ; the males consist- 

 ing of go stamens, destitute of perianth. The female flowers closely 

 glomerulate on common receptacle ; calyx 4-phyllous. Germen 

 semi-inferior, 1 -ovulate ; style thin cylindrical, 2-fid at apex; legs
