This ornamental stove Aroid is a hybrid raised by the 
firm of Messrs. Makoy of Liege, for which they were awarded 
a Certificate of Merit by the Royal Agricultural and Botanical 
Society of Ghent in 1887. Its parentage is not mentioned, 
but judging from the purple tint on the under surface of its 
leaves, a coloration which is unusual in the genus, it is 
possible that P. verrucosum, Mathieu, may have been one of 
its parents. When young the leaves are deeply tinged with 
coppery brown, but as they become older this colour almost 
disappears, as in the leaf figured. For a climbing species it 
appears to be of comparatively slow growth, since the plant 
at Kew, from which our figure was made in May last, was 
acquired in 1898, and is now only about 8 feet high, with a 
spread of about 6 feet. 
Description.—Stem climbing, rooting, 1-2 in. thick, 
clothed with brown fibrous scale-leaves on the upper part. 
Leaves spreading, 1-3 in. apart ; petiole 11-2} feet long, in 
the larger leaves about } in. thick at the middle, terete, 
with a slightly rough surface, green ; blade 14-2} feet long, 
January, 1908.
