448 THE ORCHID FAMILY. [Ophryt. 



and all turned down, 2 lateral ones very downy, 3 terminal ones con- 

 . cealed under the lip, the middle one often again turned upwards, bat 

 very variable in length. Column erect, with a distinct beak above the 

 anther. 0. Trollii, Heg. 



In dry pastures, usually in limestone districts, in central and southern 

 Europe, not farther north than central Germany and Belgium. In 

 Britain, chiefly in the southern and eastern counties of England, occur- 

 ring more sparingly in other parts of England and in Ireland, but not 

 in Scotland. FL early summer. [0. arachnites, Hoffm., is a variety with 

 broader petals and a longer lip.] 



2. 0. aranifera, Huds. (fig. 1014). Spider 0. Much like 0. apifera, 

 but the sepals are green with less of pink, the petals very short, the 

 beak of the column is straight, and the lip is broader, of a dull brown, 

 variously marked with paler spots in the centre, convex as in 0. apifera, 

 but the edges obscurely or very shortly lobed, and either not turned 

 under or but very slightly so. 



In dry pastures, with nearly the same range as 0. apifera, rather 

 more common in southern Europe, less so northwards. Much more 

 rare in England than 0. apifera, and unknown in Ireland. FL spring 

 and early summer. [0. fucifera, Sm., is a variety with the petals downy 

 within, and usually entire tip.] 



3. O. muscifera, Huds. (fig. 1015). Fly 0. A much more slender 

 plant than the two preceding species, with narrow leaves, and a slen- 

 der spike of 3 or 4 flowers. Sepals oblong or narrow-ovate, greenish. 

 Petals very narrow-linear. Column short, without any beak. Lip 

 much longer than the sepals, oblong, convex, of a purplish brown, with 

 pale-blue or white marks in the centre ; the 2 lateral lobes turned 

 down, the central one larger, with a deep notch. 



On dry pastures in central Europe, extending farther east than the 

 two last species, but not near so common in the south. In Britain, 

 spread over England, and abundant in some of the eastern and south- 

 eastern counties ; very rare in Ireland ; hot in Scotland. Fl, spring 

 and early summer. 



XVI. CYPRIPEDIUM. LADY'S SLIPPER. 



Rootstock fibrous. Leaves large. Flowers few, with a large inflated 

 lip. Column terminating in a dilated, incurved, thickish, petal-like 

 lobe, below which are 2 distinct anthers, 1 on each side. 



A considerable and very distinct North American and Asiatic genus, 

 with one species extending into western Europe. 



1. C. Calceolus, Linn. (fig. 1016). Lady's Slipper. Stem 1 feet 

 high, with large, ovate, pointed leaves, the upper ones lanceolate, and 

 1 or rarely 2 large showy flowers on long peduncles. Upper sepal 

 opposite the lip, broadly lanceolate, 1^ inches long, a similar one 

 (formed of the 2 lateral ones combined into 1) under the lip ; the 2 

 petals nearly as long, linear and spreading ; all of a brown-purple. Lip 

 very large and inflated, compared to a slipper, yellow, variegated with 

 purple. Column very much shorter than the petals. 



In woods, in northern Asia and eastern Europe, almost to the Arctic 

 Circle, rarer over western Europe. In Britain, found only in Durham 

 and Yorkshire. Fl. early summer.
