Leaves mostly radical, scapes simply spiked or panicu-

including 7. Usneoides of the United States, presents a 
filiform and diffusely dichotomous stem with alternate 
and filiform leprose leaves, accompanied by peduncles 
_ which are 1 or 2-flowered, and a capsule of 1 cell. Scarcely 
congeners with those splendid species of the tropics, 
which depending for parasitic nourishment on the boughs 
and trunks of trees, have their leaves convolutely im- 
bricated so as to retain as in a vase supplies of water 
which endure for several days together; these produce
