ventrally lateral towards the apex of the style. Follicles 

 binate, horizontally patent, IJ- nearly 2 cm. in length through 

 the two pollicles, oblong, with a curved and dried style at the 

 apex, with a thin carpel, compressed, quadrangular, abruptly 

 truncate at the superior part of the ventral suture with an 

 obtuse angle, glabrous, undulate, coste. Seeds 10-12 to each 

 carpel, globose, nearly 1 mm. each way, with a short minute 

 spongy and whitish funicle, ascending, shining, yellowish brown, 

 with a narrow and slightly prominent rhaphe ; albumen copious, 

 white, fleshy ; embryo minute, sitting at the base of the albumen ; 

 cotyledons shorter than the hypocotyl. Seedling : cotyledonaly 

 leaves 2, equal in size and form, ovato-elliptical, retuse with a 

 minute obtuse projection at the apex, thin, herbaceous, green,

There are several species of this genus in Japan, of which 

 this is a rarer one, being, at present, found growing only on 

 the mountains of the provinces of Uzen, Echigo, Echizen, and 

 Rikuzen, in flower during April-June. The squamose rhizome 

 constitutes the best character to distinguish this species from all 

 others of the genus ; and the leaflets have a resemblance to 

 those of /. stoloniferum Maxim., though quite diflerent in es- 

 sential characters. In 1879, A. Franchet first described this 

 species from specimens collected by R. P. Faurie, in his "Stirpes 

 nov£e vel rariores florge Japonicae" in Volume XXVI of the 

 "Bulletin de la Societe botanique de France." In the Herba- 

 rium of the Science College, Imperial University of Tokyo, there 

 are some specimens of this species, collected by R. Yatabe and 

 S. Okubo on Mt. Godzu in the province of Echigo on August 2, 

 1886, and Mt. Yudono in the province of Uzen on July 22, 1887, 

 and they are all in ripe fruit. My figures in "Icones Florge 

 Japonic^ " were drawn from living specimens cultivated in the 

 Koishikawa Botanic Gardens.
