A coarse-growing and very rigid plant, with a habit not unlike 

 some of the larger specimens of SjwrocJums scoiiciria. Difi'erent 

 specimens vary considerably in appearance, owing to the greater 

 copiousness of the branches and ramuli in some, and their diffe- 

 rent proportionate length. Younger specimens are frequently 

 clothed down to the very base of the stem. These variations 

 have given rise to the supposed existence of two species, C. iner- 

 mis and C. caudafa, which however cannot be separated by any 

 tansrible characters. 



I regret that I have been unable, on any of my numerous spe- 

 cimens, to detect spores or paranemata in the mitra^form terminal 

 tubercles, which externally resemble receptacles, and which, ac- 

 cording to Turner, are the fruit. Either they are receptacles in 

 a very imperfectly organized condition, or merely glandular tips. 

 Future observations must be waited for, to settle this question.
