448 THE ORCHID FAMILY. 
and all turned down, 2 lateral ones very downy, 3 terminal ones con- 
cealed under the lip, the middle one often again turned upwards, but 
very variable in length. Column erect, with a distinct beak above the 
anther. O. T'rolli, 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. [O. arachnites, Hoffm., is a variety with 
broader petals and a longer lip. ] 
2. O. aranifera, Huds. (fig. 1014). Spider O.—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 O, 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 O. apifera, rather 
more common in southern Europe, less so northwards. Much more 
rare in England than O. apifera, and unknown in Ireland. Fl. spring _ 
and early summer. [O. fucifera, Sm., is a variety with the petalsdowny — 
within, and usually entire tip.] 
3. O. muscifera, Huds. (fig. 1015). Fly O.—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; not in Scotland. Fl. spring 
and carly 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 inte western Europe. 
1. ©. Calceolus, Linn. (fig. 1016). Lady’s Slipper.—Stem 13 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, 14 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. ;
