This is a fine plant, which has been known in cultivation 
for several: years, but which has never been figured or 
even fully described. Its nearest ally is P. albiflos, Herbert 
in Bot. Mag. t. 2642, (Cochliopetalum albiflos, Beer), but this 
has milk-white flowers and narrower leaves, green on the under- 
side. By Karl Koch, in his monograph of this large and 
intricate genus above cited, it is placed doubtfully under 
P. odorata, Regel in Gartenflora, tab. 114, (Cochliopetalum 
Schuchii, Beer), but this also is a plant with milk-white 
petals and leaves green on both surfaces. Its precise country 
is not known, and I have looked for it in vain amongst the 
wild specimens of Piteairnia in the London herbaria. Our 
drawing was made from a plant that flowered in the 
Palm Stove at Kew in April of this present year. 5 
Descr. Acaulescent. eaves about twenty in a dense

an inch and a quarter broad at the middle, narrowed to the 
point and downwards to a channelled hatt three or four lines a 
broad, not a proper petiole, bright green on the face, white — 
furfuraceous all over the under surface, entire thout — 
marginal prickles. Scape a foot and a half long,
