 it, and also growing in abundance was L. couiplanatnm, and the 

 very great difference in the appearance of the two plants, both as 

 to color and habit, at once attracted our attention. Further field

 the tough sod at the periphery of the area covered by the colony, 

 and which I have myself verified in many individuals subsequently 

 found near Cold Spring, Long Island. The rhizome of this plant 

 is, moreover, supplied with lanceolate to ovate leaves which are 

 contracted at the base, and is white, except when, as is sometimes 

 the case, the plant is forced out of its normal direction by hard
