mountainous districts of Jamaica and Cuba. It has been 

 very recently collected near the city of Teapa, in Mexico 

 (growing there also on trunks of trees) by Mr. J. N". 

 Rovirosa, from whom there are specimens in the Kew 

 Herbarium. The H. tuxtlensis of Mexico, alluded to by 

 De Candolle, as having two bracts and two calyx lobes, 

 will in all probability prove to be H. tetrandra, 



H. tetrandra was obtained by the Eoyal Gardens from 

 Messrs. V. Lemoine and Son, of Nancy, in March, 1893, 

 and it flowered in October of the same year, when only 

 about a foot in height.
