 ing exceptions to this rule liav(! nicently been made; known, such as tho discovery of 

 our Tipnhir'ui discolor, or of a species v(!ry like; it, in the Sikkiin Himalayas. Tlie pres- 

 ent expedition has detected in Japan two Ordiids, which were until now sup]»0N(;(l to be 

 peculiar to North America east of tho Mississippi, vi/. lAparis liliifoUa, and I'ot/iuiitt 

 op/iiof/fossoldes. The latter was gathered both at Simoda, in the sonthern jjart of Nip- 

 pon, and at Ilakod.'uii in tlie ishiiid of .l(!SSO. In th(! United Stiites, tliis s|)ecies is 

 commonly, if aiot always, accompanied by (Jahyponoii. piUclicUus. lu plaec; of tliis, 

 among the specimens gathered at JIakodadi, were mingled those of a m;w Arelhustt,-]' — 

 another genus equally peculiar to Eastern North America, when; the beautiful A.

namely, Orchis aristata of Fischer, which is regarded as a mere form of thi; l'luroi)ean

As respects Orontium, Kndlicher's description (drawn from Hooker's figures) of the ovule as "ImKilnrc, 

 transversum, cxcentriee amphitropum," which has been inijiiicitly .'idofiled ever since, is correct in only on<',
