We have the Birds-nest Orchid {Neottia Nidus-avis), which is leafless; its stem is pale brown, and itsflowers, arranged in a spike, are dingy brown. It isfound in many p irts of England and Ireland, also inSouthern and Central Scotland, in the humus of dampwoods, but it is not common. The Coral-root Orchis{Corallorhiza innata) is very rare; it has a repeatedlybranched rhizome, resembling branched coral, hence thename. There is no true root. The leaves are reducedto mere scales; the stem and flowers are a greenishyellow. The plant is found only in the East of Scot-land, in moist woods. The Yellow Birds-nest {Mono-tropa hypopitys) belongs to the Heath Family, occurs in the humus of Birch, Beech, and Fir woods Plate TOOTHWORT [hathrxa squamana).Order parasitic Calyx 4.

It is found in Europe and North Asia,also in North America; in Southern Europe it is analpine. Some forest trees, such as Pines, and alsoHeaths, which flourish in an acid humus soil, are servedby subject-fungi, and thus are to some extent sapro-phytic through their agency. In the course of time theymay become total saprophytes—a not over-glorious issue. Parasitism in plants is in many instances complete,in others only by way of becoming complete. Parasiticplants are interesting as indicating the length to whichplant-life will go in its determination to exist; but theyalso point a moral in which the example elicits adegree of contempt.
