49. Barringtonias Foust. — Flowers hermaphrodite, 4- or rarely 

 5-merous ; receptacle concave obconical or sacciform, scarcely or not 

 at all produced beyond the germen adnate within. Calyx valvate, 

 finally 2-4-fid (j^zt^om'ca *) or imbricate 3-4-lobed (Stravadium^). 

 Petals 4, 5, epigynously inserted and alternating with sepals, imbri- 

 cate. Stamens oo , at base connate with petals in a short ring and 

 falling with them ; filaments otherwise free, exserted ; anthers small, 

 versatile or rarely subbasifixed, 2-rimose. Disk epigynous sur- 

 rounding with a short ring the top of the germen and base of style. 

 Germen inferior, 2-4-locular ; style simple, often subulate, scarcely 

 or not at all dilated at stigmatose apex. Ovules in cells 2-oo , trans- 

 verse or descending, 2-seriate, or the inferior descending ; micropyle 

 introrsely superior. Fruit fleshy or oftener fibrous, often 4-angular, 

 crowned with persistent calyx, indehiscent. Seed generally by 

 abortion 1, testa oftener thick ; embryo exalbuminous fleshy undi- 

 vided corticate. — Trees or shrubs ; leaves alternate, often crowded at 

 top of twigs, entire, crenate or serrate, penninerved im punctate J 

 flowers in racemes or spikes, sometimes broken or very elongate ; 

 bracts small caducous ; bracteoles 2, very small or 0. (Trop, regions 

 of old world.) — See p. 326. 



60 ? Planchonia Bl,^ — Flowers nearly of Barringtonia^ 4-merous; 

 sepals 4, imbricate. Stamens oo ; anthers small, versatile ; the interior 

 longer anantherous. Germen 3-4-locular ; cells co .ovulate. Berry 

 corticate, crowned with calyx. Seeds few; funicle elongate ; cotyle- 

 dons of involute circinate embryo foliaceous plicate ; radicle very long 

 clavate spirally convolute.- — Trees ; leaves alternate crenate impunctate 

 and other characters oi Barringtonia)'^ flowers terminal,^ shortly race- 

 mose ; bracts and bracteoles not caducous, oblong.^ [Indian ArcMi:>}^)
