pilosnlate towards the base externally, glabrous internally except the 

 pubescent-villosulate base, 3-4-nerved on each side of the midrib with small 

 venules between them, somewhat shorter than the labellum ; front sepals 

 connate into one, much smaller and narrower than the dorsal sepal, turned 

 downwards, 13-18 mm long, 6-9 mm broad, oblong or ovate-oblong, bifid 

 with subdivergent and acute teeth at the apex, entire, ciliated, glabrous 

 within, pubescent-villosulate outwards, moderately attenuated at the base, 

 with 2 nerves and the several venules running to the apical teeth, thin in 

 texture. Petals horizontal, somewhat oblique-ovate or subrhombic-ovate, 

 gradually attenuated and prolonged upwards with a thickish rounded- 

 spathulate apex about 3 mm wide, shortly attenuated at the base, nearly 

 equel to the front sepal in length, 5J-7 mm wide, thin, glabrous, but 

 villose at the base, with a midrib and several venules on both sides of the 

 latter. Labellum hanging, shortly unguiculate ; the unguis canaliculate in 

 front, 2 J mm long ; pouch 23-31 mm long, semi-obconico-globose, rounded 

 at the bottom, ventricose, thin, flaccid, suddenly contracted with the reflexed 

 margins towards the base and at length connecting to the unguis, glabrous 

 on both surfaces, but villose in front of the basal portion of the inner 

 surface as is the unguis, mouth broadly open, with entire margin. Gynoste- 

 mium about 9 mm in length including the staminode, narrow, straight, but 

 curved downwards at the apex towards the dilated thick rhombeo- 

 rounded stigma which is 3 J mm across at face, and with an anther 

 on each lateral side of the apical curved part ; staminode large, projecting 

 forwards, very shortly pedicellate, nearly lunato-oblong, 5-5± mm long, 

 conduplicate, with entire and arcuate margins, emarginate at the apex. 

 CVary slightly curved forwards, slenderly cylindrical-oblong, 1 J cm long in- 

 cluding the short pedicel, 2|-3 mm broad, shortly contracted upwards, 

 slenderly attenuated towards the base and at length forming a short pedicel, 

 densely pubescent with short patent hairs all over.

Hab. Prov. Shinano: Mt. Togakushi-yama (R. Yaiahe ! herb. Sc. Coll. 

 Imp. Univ. Tokyo, July 11-12, 1884 ; 8. Matsuda ! July 28, 1893). 



A species very closely allied to Cypripedium guttatum Sw. Perianth 

 yellowish green, and labellum purpurescent. It is remarkable by the clavato- 

 spathulate apex of the petals. Mr. E. Tokubuchi informed that this species 

 is also found in Hokkaido. {To be continued.)
