This plant, nearly allied to Melittis, appears to differ in its calyx co- 

 tolla, anthers and perhaps by its glands. I have therefore inserted L mi- 

 trnt- description that it may be compared with that genus. Its habit is 

 peculiar, each whorl when in flower appears to be on the summit of the 

 stem, two flowers generally shoot up at a tmie, these are large for this or- 

 der, rather exceeding an inch in length, and are fancifully said to resemble 

 two ears, sometimes, though very rarely, all the flowers of the whorl ex- 

 pand at the same time. While the first whorl is floweriug,the stem insen- 

 sibly extends, and wheh the first flowers have decayed a second whorl ap- 

 pears on the summit of the stem ready to expand' its two most forward 

 buds. There are rarely more than three or four whorls, on each stem. I 

 have named this genus in commemoration of the late Dr, James Macbride 

 whose untimely death, IVIedicine and Natural History, and an admirmg- 

 country equally deplore. ^
