at the top of the stein, the branches -usually repeatedly divided; bracts 

 petiolate, spreading, unequal in size, broadly rounded or obliquely and 

 broadly cunea to-ovate, crenate with 2 to 5 semiorbicular and minutely 

 emarginate teeth. Flowers laxly disposed, small, glabrous, shortly pedi- 

 cellate, 3-3 J mm. in diameter. Calyx-tube obconical, ribbed longitudinally; 

 lobes 4, 2 larger than the other 2, patent in flower, deltoid, obtuse, 

 the vein obscure. Stamens 8, minute, shorter than the calyx- lobes ; 

 filament subulate ; anther rounded, yellow. Disk thickish, fleshy. Styles 2, 

 apart, divergent ; stigma terminal. Ovules numerous, oblong. Capsule 

 with persistent calyx and pedicel enlarging after anthesis, slightly compressed 

 laterally ; carpels campanula te after dehiscence. Seeds numerous, ellip- 

 tical-oblong, reddish- ferruginous, very minutely papillose on the whole surface.

A southern variety ; it differs from the typical one by the more 

 luxuriant bracts, and innovations with minute scales instead of having 

 the normal leaves. 



A. Franchet, in his monograph, described the seed of Chryosplenium 

 flageUiferum Fr. Schmidt, as " semina ovalia, lucida, glaberrima," but it is 

 in truth minutely papillose in all Japanese ones examined by me, and 

 collected from various localities.
