This curious thing flowered in the garden of the Horti- 
eultural Society in June last, having been presented to that 
establishment by the Court of Directors of the East India 
Company, with other singular plants from Aden. It forms 
one or two fleshy stems, like those of a Plumieria, on the top

less-stunted branches there appear many very handsome rose-
