E. inelegans. Desmocephalum inelegans, Hook. f. (3), 209 ; Anderss. 

 (1), 178, & (2), 69. — Charles Isl. : Darwin. Endemic. 



E. repens. Microcoecia repens, Hook. f. (3), 209; Anderss. (1), 

 179, & (2), 69. — Albemarle Isl.: Tagus Cove, alt. 1230 m., Snod- 

 grass & Heller, no. 880 (hb. Gr.). James Isl. : Darwin (hb. Gr.). 

 Endemic. The plant from Albemarle Island differs from the original 

 material from James Island in not rooting at the lower nodes. Further- 

 more, the outer bract of the involucre is broadly obovate and subtruncate 

 instead of acuminate as described by Hooker. Mr. W. B. Hemsley has 

 been so kind as to compare the Albemarle plant with some of the 

 original material at Kew and regards them as the same species. A 

 fragment of the Darwin plant, sent many years ago by Mr. Bentham to 

 Dr. Gray, is unfortunately sterile, but agrees closely with the Albemarle 

 plant in all vegetative features except in its evident repent character.
