140 EIGHTEENTH ANNUAL REPORT ON THE STATE CABINET. 



ARIetinum, R. Br. Ram's-hcad Cypripedium. 



Cold swamps, in moss and deep black soil. Summit lake. Otsego county, in 

 the half-open sphagnum bog-land adjoining, within clumps of low tamaracks 

 and arbor vit;v, or in their shade. In similar stations at Mud lake; but most 

 abundant on the tamarack marshes near Jordanville, on the road to Richfield 

 springs. Herkimer county. Usually growing singly or two or three together, 

 but often in clusters of ten to twenty stems. Stems compressed, enclosed by 

 three sheaths at base, clothed with minute down, knotted at the baaes of 

 leaves, twisted so that the leaves appear on all sides and not in opposite 

 ranks as in other species. Leaves three to six, ciliate, smooth above and 

 silvery-cellular beneath. Flower-bract large, ovate, leaf-like. 



This species, which has proved to be so rare and transitory, in these 

 stations appears both plenty and permanent. This is the more remarkable, 

 because occurring so far south; the plant being a northern one, and this 

 habitat one of its limits southward. 



Formerly, it has been found along the Rolle-boom near the Platte-kill, 

 Schenectady county, by Pearson ; and near Oneida lake, by Gray ; but the 

 plants have disappeared, or the stations are lost. Rare. May.
