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 

 Martins has published an excellent figure. I have kept it separate from Fra;- 

 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 Frcelkhia, 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.
