PITCAIRNIA undulatifolia. Hortul. 
A native, probably, of Brazil, but of the history of which we 
know nothing, save that it was sent to the Royal Gardens of 
Kew from Liverpool, by our obliging friend Mr. Shepherd, 
under the name here adopted. It is a very showy plant, and no 
stove collection should be without it. The leaves are handsome, 
and of a light green, the lower bracteas are furfuraceous below, 
red tipped with green, and the long, protruded corollas are quite 
white. It flowers in May and easily bears parting at the root. 
Desc. Plant about a foot and a half high to the top of the 
Spike. Stem rounded, sheathed in a dichotomous manner with 
_ the bases of the leaves. Leaves long-lanceolate or reniform, thin, 
membranaceous, striated, entire, glabrous, very much acumi-
