Every greenhouse where new plants are cultivated has 
been covered with the beautiful flowers of this species 
during the present season, and in some places it has even 
produced its blossoms out of doors. It first made its appear- 
ance at Mr. Knight's Nursery in the King’s Road, where 1t 
received its specific name, having been supposed to be the 
produce of seeds sent from Ceylon by Mr. Lear. It 1S, how- 
ever, not to be found among any of the Indian species either 
described or occurring in the herbaria to, which I have 
access ; nor is there a trace of it among the rich collection of 
Ceylon plants in my own possession. 
It has also been raised in the garde 
Society from seeds sent from Buenos Ayres by J. H. Man- 
deville, Esq. to the Hon. W. F. Strangways; and its whole 
habit is at variance with that of a species from a tropical 
island ; for it dislikes heat and flourishes in a cool atmo- 
sphere. In fact it is very near Ipomoea, now Pharbitis, muta- 
bilis, a beautiful Vera Cruz species, figured in the first volume 
of the Botanical Register, t. 39, from which it differs prin- 
cipally in its calyxes being very little hairy, and in its Ss 
wanting the thick pale down which covers the underside o 
the foliage of that species.
