320 EXPEDITION TO JAPAN. 



glabro intus lamellis 5-7 acutissimis (3 centralibus majoribus) eximie percurso. — Serapias 

 falcata, Tlmrib. Fl. Jap., p. 28? Dry woods, Simocla. Plant about a foot high, with nearly 

 the foliage of C. rubra ; the flowers smaller than those of C. pallens ; well distinguished from 

 all the described species by the deep and spur-like sac at the base of the labellum, and the remark- 

 ably salient lamella? of the broadly dilated epichilium. It appears to be most allied to 0. acumi- 

 nata, Lindl., (which I have not seen,) but the leaves are hardly acuminate; the epichilium not 

 bearded in any part, much broader than long, and its lamella? very conspicuous. It is likely 

 enough to be Thunberg's Serapias falcata, the upper leaves being commonly conduplicate in the 

 dried specimens, and then somewhat falcate ; but there is not sufficient evidence of it to warrant 

 the adoption of that specific name. I have not been able to consult the figure in Thunberg's 

 Icones PI. Jap. 



Spiranthes australis, Lindl. Gen. & Sp. Orchid., p. 463? Dry woods, Simoda ; June. 

 The labellum is glabrous. 



Orchis aristata, Fischer; Lindl. I. c.,p. 262. 0. latifolia, var Beeringiana, Cham. & Schlecht. 

 Hakodadi. The same as the plant of Kamtschatka and the Aleutian Islands. Ledebour, 

 following Chamisso and Schlechtendal, receives it as a variety of 0. latifolia; but it appears 

 distinct from the European plant. 



Ctmbidium: too poor to determine; apparently not C. ensifolium. Simoda. Without foliage. 



Calanthe discolor, Lindl. Bot. Beg. 1840, t. 55. Scapo puberulo foliis oblongis concoloribus 

 longiore ; racemo laxo multifloro ; sepalis petalisque (fusco-purpureis) mucronatis ; labello 

 (albo vel roseo) columnar omnino accreto profunde trilobo ima basi breviter barbato et tricristato, 

 lobis cuneiformibus, intermedio minore basi longius attenuata tricostata, disco lamellis 3 (rarius 

 1-2 obsoletis) petaloideis conspicuis instructo; calcare tenui incurvo, apice nunc subulato vel 

 acutato ovarium excedente. — Simoda. This handsome species is evidently the one figured by 

 Lindley, above cited, of the habitat of which he was uncertain. But the lamella? of the lip in 

 our specimen are larger, sometimes half as large as the lobe that bears them, and extended 

 higher up on its disk. They vary in size, however, and the lateral ones are occasionally smaller, 

 or one of them obsolete. 



Oypripedium Japonicum, Thunb. Fl. Jap., p. 30. Hill-sides, Simoda. A most striking spe- 

 cies, on account of its single pair of large, fan-shaped leaves. 



Iris Japonica, Thunb. I. squalens, Thunb. Fl. Jap., p. 33. Simoda; along water-courses. 



Iris versicolor, Thunb. Fl. Jap., p. 34. Simoda. Too poor for proper determination; but 

 not the North American species. 



Aletris Japonica, Lamb., non Thunb. Hypoxis spicata, Thunb. Fl. Jap., p. 136. Simoda. 

 Distinguished from the American species by the linear and grass-like leaves, the glandular 

 pubescence of the scape and flowers, and the shorter perianth. 



Smilax Japonica. S. China, Thunb. Fl. Jap., p. 152. Coprosmanthus Japonicus, Kunth, 

 Enum. 5, p. 268, licet loculi uniovulati! Simoda and Hakodadi ; also Webster Island, on dry 

 hill-sides. This accords so well with the description by Kunth, that for the present I am forced 

 to think it the same species, although I find the ovules solitary in each cell. Even if the ovules 

 were in pairs, I should none the less refer this ligneous and prickly species to Smilax, and con- 

 sider that it demanded the reduction of Coprosmanthus to a subgenus, for which Dr. Torrey 

 originally proposed it. 



Trillium erectum, Linn. var. album, Pursh. Hakodadi ; in pine woods. I see no difference 

 between this and the plant of the Northern United States, (which we still, with some misgiving,
