Court of Directors of the East India Company. It is loaded 

 with delicate pale rose-coloured flowers, which are arranged 

 along the stem, and when gathered and placed in water in a 

 sitting-room, it will continue to expand them for four or five 

 weeks successively.

The errors that have been committed about the source of 

 the drug called Jalap are not a little remarkable. By one 

 writer the drug was asserted to be the roots of the Common 

 Marvel of Peru ; and then it turned out that Jalap does not 

 come from Peru. By another the Convolvulus Jalapa or 

 Ipomcea macrorhiza of the southern states of the American 

 Union was asserted to be its origin ; but unfortunately that 

 plant happens to have no greater purgative qualities than 

 the common Sweet Potatoe. Then it was proved upon the 

 authority of Dr. Schiede, and others, that a plant called 

 Ipomcea, or Exogonium, Purga, was the real origin of the 

 drug, for this traveller saw the people of Xalapa collecting it. 

 But it was also asserted that other plants of the Convolvula- 

 ceous order are gathered ; and a Convolvulus orizabensis, 

 with hairy stems and calyx, was said to be one of them. It 

 now appears that the Mexicans call at least one more species 

 " Purga," adding to it the term Macho or male; for Mr. 

 Hartweg has sent home the subject of the present notice, 

 which is altogether different from any of the species previously 

 noticed as either "Purga" or " Purga Macho." What makes 

 it the more interesting is its extraordinary beauty, which I 

 think excels that of any of the species yet in gardens. The 

 only plants of it in the country are two in an unhealthy state 

 in the garden of the Horticultural Society. They have large 

 oblong fleshy tubers, and produce flowers of the richest and 

 most brilliant crimson, or rather purple, which it is possible 

 to conceive. Unfortunately it has not yet been possible to 

 propagate them.
