S. Wallisii, @. 7. Masters in Gard, Chron. 1875, I. p. 558 (cum ic. xylog.). 
One of Mr, Wallis’ important discoveries in Tropical 
America, introduced to cultivation by Messrs. Veitch ; ex- 
hibited two years ago in flower, and described, together 
with an excellent woodcut and detailed analysis, by Dr. 
Masters in the ‘ Gardeners’ Chronicle’ about the same time. 
The pure ivory-white nodding spathes, freely developed 
amongst the clustered dark shining green leaves, render this 
plant one of the most valuable of our stove Aroids for orna- 
mental culture. It belongs to asmall genus consisting 
altogether of but four or five species, peculiar to Columbia, 
Peru, and Northern Brazil. 
Duscr. Stem erect or ascending two to three feet high, 
terete, glabrous, about as thick as the thumb, giving off 
copious wrial roots from the lower nodes. Leaves rather 
numerous, dark-green and shining above, paler beneath, 
lamina obliquely-oblong or ovate-lanceolate, acute or acumin- 
ate, base unequally rounded; midrib depressed above, pro- 
minent beneath, venation rather obscure ; about’six to seven 
inches long, two to three inches broad ; petiole closely am- 
plexicaul, laterally compressed and slightly channelled
