the two are identical. The resemblance is hard to find between 
 Blozamti and the one specimen we have from Dr. Focke of 
Rh. thyrsiflorus. We know the former well, and have large series of 
specimens in our herbaria. Not one of these seems near to the 
figure of R. thyrsiflorus in Rub. Germ., which differs from them 
er point 
great part ultra-axillary (that of R. Bloxamii being lax below, with 
long rigid branches, and leafy almost or quite to the réendiel top). 
British botanists will have no difficulty in distinguishing R. 
Bloxamiifrom R. Babingtonii. With R. multifidus it was identified in 
the See Brit. _— on specimens supplied by Mr. Friderichisen ; 
re allows proximity, but seems to deny the seat? After 
the fullest consideration, therefore, we are disp to retain 
lowamtt in our list, and to consider FR. epriihee us as still 
unknown in the British Isles.

specimen we have of the latter, labelled « . tune Wh. &

imperfectly known ioe, and it would be unadvisable to give up a
