receptacle and crowned with thick epigynons disk ; style short, at 

 apex stigmatose 2-lobed. Ovules 2 ; funicle subapical very short 

 (or 0). Fruit dry coriaceous, indehiscent, elongate-obovoid, some- 

 times longitudinally cortulate, sericeous, crowned with persistent 

 calyx. Seed 1, descending, conformed to cell ; cotyledons of exal- 

 buminous embryo highly convolute. — Small trees ; leaves opposite 

 petiolate, elliptical or oblong, obtuse, entire thick coriaceous, 

 2-glandular at base ; flowers ^ in axillary and terminal ramose spikes, 

 often 3-spiked. {Trop. America and west coast of trop. Africa,'^) 



5. Macropteranthes F. Muell.^— Flowers hermaphrodite (of 

 Laguncularia) , 5-merous. Stamens 10, or fewer; anthers sometimes 

 ciliate. Germen adnate within to cavity of receptacle not constricted 

 at apex and laterally winged with 2 adnate bracteoles. Ovules in 

 cell 10-16, inserted under apex by linear-elongate funicles. Fruit 

 (indehiscent ?) crowned with calyx and augmented to middle by 2 

 wide foliaceous horizontal wings ; seeds . , . ? — Small sericeous trees ; 

 leaves opposite or fasciculate small entire ; flowers axillary 2-nate 

 on peduncle. {Trop, Australia^) 



6. Guiera Adans.^ — Flowers hermaphrodite (of Comhretum), 

 5-merous ; receptacle attenuate on both sides, produced beyond 

 germen. Petals 5, narrow, perceptibly dilated at apex. Stamens 

 10, exserted ; anthers small didymous. Germen, disk, etc., of 

 Lumnitzera ; ovules 4, 5 ; funicles elongate. Fruit coriaceous, 

 indehiscent, elongate-cylindrical and curved,^ sericeo-villose, crowned 

 with persistent calyx. Seed 1, narrow ; cotyledons of exalbuminous 

 elongate embryo convolute. — A somewhat tomentose shrub ; leaves 

 opposite, petiolate, entire apiculate black-spotted ; flowers ' crowded 

 in axillary globose solitary pedunculate capitules; bracts 4, foliaceous 

 inserted under capitule, valvately con ni vent in common involucre 

 around enclosed flowers, finally reflexed at anthesis. {Trop. west.
