I take this opportunity of defining a new g-enus of 

 Mexican Orcludacea3 received by the Horticultural Society 

 from the neighbourhood of Vera Cruz, where it was found 

 by Mr. Theodore Hartweg, after whom, as the original 

 Hartwegia proves to be nothing but Chlorophytum, I have 

 named it.
