or squarely rounded, even transversely broad, truncate or obscurely tricuspidate 

 at the apex, subembracing the base of the pedicel, faintly 1-nerved, but in 

 some forms, sometimes narrowly or rounded ovate, rounded obtuse at the 

 apex, embracing the base of the pedicel, trinerved, J-3 mm long. Calycules 

 3, situated jnst below the flower, minute, J-l mm long, usually free or 

 slightly connate at the base, oval or orbicular-oval, shallowly concave, very 

 obtuse or retuse, entire or obscurely irregularly waved, membranaceous, 

 colourless, nerveless, one of them smaller than the others ; sometimes 

 strongly connate, nearly 3-lobed. Perianth rather erect, campanulate ; seg- 

 ments 6, free, spathulate-oblong, or slenderly oblong, rounded obtuse at the 

 apex, entire, membranaceous, shallowly concave, white, one-nerved, the 

 nerve light green (?), disappearing in some point about one-third from the 

 apex, the outer perianth 2 mm long, somewhat shorter than the inner, 

 the latter about 2J mm long, persistent. Stamens 6, free, opposite 

 to the perianth segments, erect, a little higher or lower than the perianth ; 

 filaments linear-subulate, thick, one-nerved, slightly adherent to the basal 

 portion of perianth at the base ; anther ovate-oval, yellowish, 2 - celled, 

 introrse, dorsifixed at the base, auricled below. Ovary cylindrical-ovate, 

 sessile, 3- or sometimes 4-celled, longitudinally 3- or 4-farrowed, somewhat 

 lower than the inner perianth, free above passing into short and thick 

 styles slightly curved outwards ; stigmas terminal, truncate, punctiform, 

 obliquely facing outwards ; each cell with a dorsal nerve. Ovules very 

 minute, elliptical, about 12-16 in each cell, 2-serial, attached along the 

 axial placenta, erect-patent, sessile. Fruit, when young, erect and exserted 

 from the persistent perianth about two-fifth of it, about 3J-4J mm long, 

 3- rarely 4-celled, turged, smooth, ovate-oblong, very bluntly attenuated at 

 the base, 3- or rarely 4-farrowed, each carpel shortly free above passing into 

 the short persistent style curved outwards ; carpel rather thin with the rounded 

 back ; pedicel erect and longitudinally perallel to the rachis. Seed, when 

 young, obovate-oblong, minute, erect-patent.

This species is unusually found in the mountainous districts in the 

 middle and the northern part of the main land of Japan, and it greatly 

 resembles T. gracilis Fr. et Sav., but the forms of leaves, bracts, and
