I, MALAXIS. MALAXIS, 
A single species, distinguished as a genus from Inparis by the proportion 
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. 979). Bog Malaxis.—A delicate plant, 
© or 4 inches in height, the rootstock producing a small solid bulb out of 
the ground like many exotic epiphytes, and 3 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 
* A single specimen has been occasionally found of species of Orchis and Habe- 
naria, in which the flowers are all deformed, without any spur, but such instances 
are very rare.
