9. ? Eriolaena DC. — Calyx 5-fid or 5-partite, valvate. Petals 5, 

 alternate, inserted with calyx ; claw dilated. Column short or 

 very short, bearing co 1-adelphous stamens; filaments connate 

 into a tube to a greater or less height, unequally free at apex ; an- 

 thers erect oblong-linear ; cells parallel, rimose ; staminodes 0. 

 Ovary very short, stipitate, 4-12-celled; style stigmatiferous stellate 

 at apex 4-12-lobed. Ovules co, ascending; micropyle extrorse 

 inferior. Capsule lignescent, loculicidal. Seeds co, winged above ; 

 embryo slightly albuminous ; cotyledons folded or contortuplicate ; 

 radicle inferior. — Trees, stellate-pubescent or tomentose ; leaves 

 alternate, petiolate, cordate ; flowers axillary solitary or in cymes ; 

 bracts 3-5, sometimes lacinate {Trop. Asia). See p. 68. 



10. Reevesia Lindl. — Calyx subclavate valvate, unequal- 3-5- 

 fid. Petals unguiculate, contorted, inserted with calyx. Column 

 erect antheriferous at apex; anthers 10-co , capitate ; cells extrorse 

 divaricate, rimose. Germen placed at summit of colnum, 5- 

 celled ; style very short, 5-lobed, stigmatiferous. Ovules 2 in each 

 cell, ascending ; micropyle extrorse inferior, capsule ligneous, 

 loculicidal 5-valved. Seeds in cells 1, 2, ascending, winged above; 

 embryo straight ; cotyledons flat foliaceous ; radicle short inferior ; 

 albumen fleshy. — Trees ; leaves alternate, entire, petiolate ; flowers 

 crowded in compound terminal racemose cymes ; bracts and bractlets 

 small often remote from flower {Tropical and Subtropical Asia). See 

 p. 69. 



11. Ungeria Schott & Endl. — Calyx clavate-campanulate- 

 valvate, 5-fid. Petals 5, inserted with calyx, unguiculate con- 

 torted. Stamens as in Reevesia. Germen inserted at summit of 

 column, 5-celled ; styles short, stigmatiferous at apex. " Ovule 

 solitary in each." Capsule subulate-5-agonal, coriaceous-ligneous. 

 :c Seed ovate globose; embryo straight; albumen copious." — 

 Trees ; leaves alternate, simple, petiolate ; flowers in dense cymiferous 

 racemes ; bracts small remote from flower {Norfolk Island). See
