At the close of the month of January of this year, the Hon. 

 W. Macleay F.L.S., Hon. Secretary of this Society, called my 

 attention to a peculiar asclepediaceous twiner which had suddenly 

 made its appearance in his shrubbery. On examination I found

 of a tropical plant as far south as this city is worthy of record, 

 and where no doubt it will soon make itself a home under the
