Our specimens of this curious plant are from Plymouth Sound, and 

 have the fruit immature. We are not aware of the species having been 

 found in a growing state in this country, although specimens have 

 apparently been picked on the south-western shores of both England 

 and Ireland in various places. 



It is said {Phyc. Brit.) to be a native of Spain, on the authority of 

 Clemeute, but we are not aware if it has been found there in the growing 

 state or picked on the beach, so that the real habitat of this curious 

 plant is still imperfectly understood. Nor does the root (?), on any 

 specimens we have seen or that of the figure in Phyc. Brit, afford any 

 clue to its nature ; it appears to be only the swollen base of the stem 

 adjacent to the real root. 



It is said to be a native of the Southern Ocean, where several other 

 allied species of the same genus occur. 



CARPOMITRA CABRERA.
