152 WILD FLOWERS OF THE BRITISH ISLES 
Tribe V. OPHRYDINE/E. — Anther wholly attached to the column ; pollen-masses, stalked ; 
pollen waxy and coherent. 
XII. Man-Orchid (Ac'eras). Flowers stalkless, hooded ; lip lowermost, 4-lobed, not spurred ; 
plants leafy. 
XIII. Insect Orchid (Ophrys). Flowers stalkless, spreading; lip lowermost, variously lobed, 
usually convex, not spurred ; rostellum 2-lobed ; plants leafy. 
XIV. Orchid (Or'chis). Flowers stalkless, hooded ; lip lowermost, 3-4-lobed, spurred ; column 
with a rostellum ; leafy plants. 
XV. Musk Orchid (Hermin'ium). Flowers stalkless, bell-shaped ; lip lowermost, 3-lobed, not 
spurred ; pollen-masses each on a large naked gland. 
XVI. Habenaria. Flowers stalkless, hooded ; lip lowermost, spurred ; pollen-masses stalked, 
each attached to a naked gland. 
Tribe I. CYPRIPEDEA2 . — Two side anthers perfect, central anther sterile ; pollen-masses not 
stalked ; pollen pulpy and granular. 
LADY’S SLIPPER ORCHID. (CYPRIPEDIUM. Linn.)— Flowers few, stalkless, large, with 
the lip large and inflated, and supposed to resemble a Turkish slipper or a French sabot, solitary, 
or 2 or 3 in a loose spike terminating the stem ; the lip lowermost (inverted), owing to the twisting 
of the stalk. The outer perianth-row has the 2 lower lobes combined, so there are apparently only 
4 similar perianth-lobes, which are all spreading ; the lip is very large, inflated, and curved upwards 
and inwards. The column is short, curved inwards, and 3-lobed, the central lobe is petal-like and 
bears a sterile anther, and the side lobes each bear one perfect anther ; the anthers are stalkless, 
and the pollen is pulpy and granular. Herbs with large parallel-veined stem-leaves and fibrous 
roots. 
Common Lady’s Slipper Orchid. (Cyprip^dium Calceolus. Linn.)— The only 
British species. As just described. A most beautiful, very large (for a British orchid), and usually 
solitary flower, with the 2 outer perianth-lobes lance-shaped, the 2 upper lobes of the inner row 
strap-shaped, all 4 maroon-coloured ; the lip large, inflated, and curved upwards and inwards, pale 
yellow ; the leafy stem i-i£ feet high, usually without any root-leaves, but with several broad 
pointed stem-leaves with sheathing bases. [ Plate 49. 
Very rare. In dense woods on limestone in Yorkshire and Durham. May — June. Perennial. 
Tribe II. MALAXIDE/E . — Anther terminal, free, like a lid ; pollen-masses not stalked, pollen 
waxy and coherent. 
II. BOG ORCHID. (MALAX'IS. Soland.) — A genus consisting of the following species : — 
Bog 1 Orchid. (Malax'is paludosa. Swartz.) — Flowers minute, numerous, stalked, 
yellowish-green, in a spike-like cluster (raceme), remarkable from the fact that the lip (labellum) 
of the perianth is uppermost, not through remaining in its natural position, but owing to the long 
seedcase being so much twisted that the flower is turned right round and back into its original 
position, instead of being twisted halfway till the lip is lowermost (inverted) as are most of the 
other orchids. Outer perianth-row of 3 lobes, broadly lance-shaped, reflexed, larger than the 
inner ; inner perianth of 3 lobes, narrower and shorter than the outer, the lip (labellum) upper- 
most, entire, concave, and not spurred at the base, but embracing the column and making the 
entrance to the flower tubular. Column very short and straight, terminated by a lid-like, 2-celled 
anther, which has the pollen disposed in 2 pairs of stalkless, club-shaped masses, all attached to a
