I. MALAXIS. BOG ORCHIS. 
A single species, distinguished as a genus from Liparis by the pro- 
portion of the petals, and by the pollen-masses, which are club-shaped, 
in 2 pairs, both suspended from a gland which terminates the column. 
1. M. paludosa, Sw. (fig. 981). Bog Orchis.—A delicate plant, 3 or 
4 inches in height, the rootstock producing a small solid bulb out of 
the ground like many exotic epiphytes, and 38 or 4 ovate or oblong 
radical leaves. Flowers very small, of a greenish yellow, in a loose, 
slender raceme. Sepals ovate or broadly lanceolate, about a line long, 
two of them erect, the third turned down ; petals similar, but not half 
the size, and spreading laterally. Lip erect, shorter than the sepals, 
but longer than the petals, ovate, concave at the base, where it embraces 
the very short column. 
In spongy bogs, in northern Europe and Russian Asia, from the 
north of France to the Arctic regions, and in some mountain districts 
in central Europe. Spread over the greater part of Britain, but very 
sparingly, and always difficult to find. Fl. summer, rather late. 
II. LIPARIS. LIPARIS. 
Delicate herbs, with radical leaves, and small, greenish-yellow flowers, 
in a terminal raceme. Sepals and petals nearly alike. Lip much 
broader, erect or spreading and entire. Column erect or curved, with 
a lid-like terminal anther ; the two pairs of pollen-masses attached by 
their summits, but spr eading laterally into the 2 anther-cells. 
Besides the European species, the genus contains a considerable 
number from the warmer regions of both the New and the Old Wore i 
several of them true epiphytes.
