peduncles are longer and the flowers not collected into capitula. The most re- 
markable character of the species consists in the ultimate ramuli of the panicle 
being so elongated and uniform in size as to resemble true peduncles bearing 
spikes of flowers, whereas they branch irregularly in the other species.

This curious plant is evidently congeneric with B. maritima, of which 
Martius has published an excellent figure. I have kept it separate from Fræ- 
lichia nudicaulis, though the latter is distinctly marked in Mr. Darwin's 
herbarium as the fruiting state of this. I can here, however, record my - 
opinion that the plants may be identical, as Mr. Darwin considers them: 
though the characters of the present agree with Bucholtzia, and those of the 
latter with Frelichia, and there being no intermediate states to show the 
transition of the one genus into the other, I feel bound, in describing them, 
to follow the present arrangement of the order, and employ the same trivial 
names for each.
