ate in terminal spikes, whorls 4-flowered, a bractea at the base of each 
flower nearly as long as the calyx, ovate, acute, dotted, fringed and sprink- 
led with capitate glandular hair. Calyx erect, striate, the border 3-cleft, 2 
segments, large, rounded, the third narrow, obtuse, a little shorter. Co- 
roila bilabiate, the tube longer than the calyx, streaked with bright purple 
and white, the upper lip entire, large, slightly vaulted, the lower lip short- 
er, 3-lohed, the lobes obtuse and reflexed. Filaments shorter than the co- 
rolla, a little hairy, appressed to the upper lip, the anthers 2-lobed, nearly 
black, villous, the lobes divaricate, very acute and as it were fringed with 
short spines. Germs 4, glabrous. Style as long as the two shorter sta- 
mens. Stigmas 2, simple, acute. A white oval gland larger than the. 
germs is placed at their base. 
This plant, nearly allied to Melittis, appears to differ in its calyx, co- 
rolla, anthers and perhaps b}^ its glands. I have therefore inserted a mi- 
nute 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 time, 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 flowering, the stem insen- 
sibly extends, and when 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, Medicine and Natural History, and an admiring 
country equally deplore. 
Grows in the narrow swamps, through the pine barrens in the middle 
districts of Carolina. Very abundant between Saltcatcher bridge and 
Murphy ? s bridge on the Edisto river.
