Himalayas from Assam to Nepal, and again in Java. Tlie plant above 

 named is a garden hybrid, raised by Messrs. Yeitch. at their Exeter nur- 

 sery in 1856. The parent plants were 0. rosea, Benth. and C, vestita, 

 Lindl. The scape is about two feet high, and 8 to 12 flowered. Flowers 

 about 2 inches across, bright rose colour, with a white spot at the base 

 of the lip. 



Ci/pripedium Sedenii, Rchb. — This is one of the " Lady's Slipper" 

 orchids. The plant under notice is the garden hybrid known as can-

1. Acrostichum Herminieri, Bory. — Rootstock short, densely clothed 

 with matted linear or filiform, undulate, bright ferruginous scales, which 

 are a third to 1 in. 1. and J li. w. ; fronds several, scimiter-shaped, 

 tufted or subtufted, quite pendant, tapering and long-decurrent at the 

 base to stipites an inch or less long, tapering and acuminate at the 

 apex 1^ - 3 ft. 1, f - 1 in. w., very coriaceous, dark glossy green, paler 

 beneath, glabrous but with scattered minute speck-like scales beneath 

 while young ; midrib immersed in the parenchyma ; veins close, forked, 

 immersed, evident above, less so or concealed beneath ; fertile fronds 

 4 - 5 in. 1. 1\ - 1\ in. w. lanceolate or lanceolate-oblong, shortly pointed, 

 the base cuneate ; petiole about 1 in. 1. 



Infrequent on trees in forests of the eastern parishes ; gathered in 

 1886 by Mr. Sherring above Bath, at 4000 ft. altitude ; a peculiar and 

 very striking species distinguished by the very long narrow sterile 

 fronds, over a yard long often not exceeding an inch wide, and the very 

 disproportional short but rather broader fertile ones, that rarely exceed 

 six inches long. Though very coriaceous, the fronds, which curve late- 

 rally, owing to one margin being shorter than the other thus acquiring 

 scimiter-shape, are not so rigid as in some of the other species. The 

 rootstock is short repent or subrepent descending, and quite concealed 

 in the copious tuft of long dense glossy scales. 



2. A. gramineum, Jenm. — Rootstock slender, creeping, naked, but 

 viscii; stipites nude, scattered but approximate, slender, 2-3 in. 1. 

 winged in the upper part by the decurrent sides of the fronds, fronds 

 numerous, erect or spreading somewhat forming grass-like patches, 

 linear, 2J-5 in. 1. 3-4 li. w., tapering equally at the apex and base, or 

 more so at the latter, chartaceous, pellucid, naked, glossy, bright green, 

 viscid throughout ; veins rather close, simple and forked, terminating 

 within the margins in clavate apices ; fertile fronds smaller, the same 

 shape, on longer stipites, Journ. Bot. 1879, p. 263. 



Common on banks and rocks at 2,000 ft, alt. ; gathered near Second- 

 breakfast Spring, beyond Mt. Moses, St. Andrew. A smaller and much 

 thinner textured plant than the next, naked in all its parts, very viscid,
