50 GYNANDRIA— DIANDRIA. Cypripedium. 



In marshy umbrageous woods in Scotland, but rarely. 



Found in one place only, and there sparingly ; in a moist hanging 

 wood, on the south side, near the head of Little Loch Broom, 

 Ross-shire. Lighffoot. In Methuen wood, 6 miles from Perth. 

 Mr. Thomas Bishop, 1804. In a peat bog among willows, a 

 little to the south of Dalmahoy hill, 9 miles from Edinburgh. 

 Mr. Edward John Maughan, 1807. At Ravelrig j Dr. Greville. 

 Hooker. 



Perennial. May, June. 



Root fleshy, of numerous, compound, divaricated, horizontal 

 branches, spreading about 2 inches, pale brownish or yellowish, 

 the lobes blunt and all distinct, not touching each other. When 

 beginning to dry it exhales the sweet a«d powerful scent of 

 Vanilla, which is not entirely lost after the specimens have been 

 preserved for 20 years. One root sent by Mr. Maughan in wet 

 moss, and so kept in a pot, with plenty of water, blossomed the 

 same summer. Leaves none. Stalks solitary, erect, a span 

 high, angular, smooth, clothed in their lower half with a few 

 distant, tubular, loosely sheathing scales, 1-} inch long. Cluster 

 of from 5 to JO drooping, pale yellowish Jloioers, on short par- 

 tial stalks, with a very small acute hractea at the base of each 

 stalk. Germcn smooth, incurved, bluntly angular. Calyx-leaves 

 lanceolate, spreading, greenish with a tinge of red. Pet. lan- 

 ceolate, pale yellow, often reddish at the point, converging under 

 the upper calyx-leaf. Lip recurved, obovate, with a slight con- 

 traction in the middle, below which, towards the base, are two 

 shallow rounded lobes, the whole white or pale yellow, more 

 or less spotted with red -, the spur not apparent, but Mr. Brown 

 conceives it to be entirely united to the base of the lip, and very 

 short. Some traces of a spur certainly exist in all the other spe- 

 cies. Column yellowish j convex at the back j channelled in 

 front; crowned with the vertical a/z^/ier in the form of a lid, and 

 attached behind as by a hinge. Pollen-masses 2 in each cell, 

 *' ovate, white." Hooker. Caps, elliptical, with 3 blunt ribs, 

 and crowned with the permanent withered flower.
