the genus Lawrencia, under the name: of L. dasyphylla and L. tenuissima, 
_whence they were removed into the more recently formed genus Chondria, 
and now they stand at the head of Professor Agardh’s most recently 
rearranged order Ahodomelacew. Professor Agardh divides his Orders 
into tribes, genera, and species. Tribe 1, in his Order, Rhodomelacee, 
is termed Chonriopsidew, and the genus Chondriopsis is represented in 
Britain by the two species C. dasyphylla and C. tenwissima. 
Fic. 91. (a) Chondriopsis dasyphylla ; (b) Magnified branchlet, with ceramidia. 
Fig. 91. represents a branch or two of the former species, with a 
magnified portion bearing ovate capsules, which are seated on the inner

generally undivided and set throughout on each side with branches, which 
lengthen towards the base of the main stems; the lower branches ‘usually 
bearing a second series, all of which are set here and there with short
