This noble Aroid has been for years a well known 
ornament of the aquarium near the Palm House at Kew, 
growing in a pot the base of which is immersed, and 
forming a crown of bright green foliage, six feet in diameter, 
and four to five feet in height. It was sent to Kew by Mr. 
- Williams, of Bahia, many years ago, flowers annually, and 
would have been published in this Magazine ere this, but 
for the difficulty of naming the plants of this genus, which em- 
braces upwards of one hundred and fifty species, many of them 
most imperfectly described. As however it agrees with none 
of those contained in Schott’s excellent monograph (1860), _ 
has not since been figured in any publication accessible to 
me, and has not been recognised by the many continental 
botanists and horticulturists who have seen it at Kew, I 
ani emboldened to describe it as new, and give it the name 
MAY Ist, 1871.
