﻿ON THE BOTANY OF JAPAN. 411 



only the Cephalanthera ensifolia, to which Dr. Linclley has already referred all the 

 Indian Cephalantherce. We have, in the collection from Hakodadi, specimens quite like 

 a depauperate form of the European C. ensifolia, and from Simoda a large variety (as 

 I must needs regard it) with all the lower flowers even more leafy-bracted than in 

 Wight's figure of C. acuminata, the like of which Dr. Lindley had never seen. The 

 labellum, likewise, is rather more saccate at the base, and the epichilium smoother. 

 Still, the few specimens gathered exhibit such transitions towards the ordinary form, 

 that I cannot hesitate to unite them. Very different from this, and a very well-marked 

 species, is my C Japonica, to which I had formerly adduced Thunberg's Sei-ajnas fal- 

 cata, with some doubt. I should now refer to it Thunberg's Serapias erecta ; yet the 

 flowers of that plant are said to be white, and, as represented, are much smaller than 

 those of C. Japonica* 4 



My Epipactis Tlmnhergii {Serapias longifolia, Thunb.) has not been again collected. 

 It resembles more than any others E. veratrifolia of the Himalayas, and E. Americana, 

 which ranges from Oregon to Texas and Mexico, and is the sole representative of this 

 European and North Asian genus in the New AVorld. 



Finally, there are one or two specimens of a Cremastra, with unopened flower-buds, 

 which I had supposed to be Blume's Hyacinthorchis variabilis ; but, not to speak of the 

 lancet-shaped process on the lip, (since the roundish, shrivelled process represented in 

 Blume's figure may not be normal,) the column is more slender, almost fiUform, and 

 at the summit abruptly dilated into a very remarkable, semi-umbraculiform, stigma- 

 tiferous body, into the hollow of which, in the bud, the process of the lip is deeply 

 inserted."]'

Li the Bonin Islands, Mr. Wright gathered a Luisia {L. hrachycarpa, C. "Wright), certainly different from 

 the Oceanic species, and probably no less so from L. teres, on account of its short-oval fruit ; but the blossoms 

 are still unknown. On one of the islands between Japan and the Loo Choo Islands was gathered a new, small- 

 flowered Aceras, near the Himalayan A. angustifoKa, viz. : — 



Aceras LONOiCRURis (C. Wright, sp. nov.) : spica densiflora ; petalis angusto-linearibus obtusis ; labello 

 deflexo sepalis plus duplo longiori pauUo ultra medium fisso cum lacinula intermedia brevi ; coet. A. angusti-
