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 it 

 received its specific name, having been supposed to be the 

 produce of seeds sent from Ceylon by Mr. Lear. It is, 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 garden of the Horticultural 

 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 Ipomcea, 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 leaves 

 wanting the thick pale down which covers the underside of 

 the foliage of that 

 October, 1841.
