about one-half the diameter, longitudinal, anastomosing and inter- 

 lacing, formed of cylindrical cells, from which arises a second series, 

 vertical, dichotomous ; their upper dichotomies elongated, close packed, 

 their joints moniliform, forming the periphery. Substance soft and 

 rather flaccid ; when dry, rather hard, rigid. Colour, rather bright 

 brownish red, yellowish green in decay. Tubercles we have not seen ; 

 they are described as spherical, scattered over the sides of the ramuli, 

 sessile or partly immersed. 



This fine species is extremely rare in this country ; we have seen no 

 specimens except those collected by the late Mrs. Grifliths, and these 

 are barren. From G. acicularis it may be readily distinguished by its 

 flattened stems, and much more numerous branches ; from G. 2)istiUatu, 

 by being branched from the very base, where it is scarcely cylindrical, 

 and the sj)ine-like branches on the ramuli being all more or less com- 

 pressed or flat. 



On the Atlantic shores of the continent, and on those of the Medi- 

 terranean, this species is said to be not uncommon, producing fruit 

 abundantly.
