72 ARKIV FÖR BOTANIK. BAND 13. N:0 15. 



It is puzzling that Gleasox did not see this species well 

 represented in herbaria; or that it has not been collected 

 by the active Cuban explorers. In fact, it is one of the easiest 

 recognized species of the Arborescentes-group and. once seen, 

 impossible to overlook. Among the species known to me it has 

 no near allies. According to the description, however, F. vicina 

 Gleasox approaches somewhat to our plant, but is distin- 

 guished by its larger involucres, which are said to be »about 

 5 — 6 mm high». Probabh' there are other differences, but it 

 is not easy to obtain an exact idea of F. vicina from Glea.sox's 

 description.

I have seen no specimens of this species. From the de- 

 scription it comes near to F. parvuliceps, but has broader leaves 

 and larger heads.

Not seen. The species seems to be a fairly well-marked 

 one, related to the preceding, but differing in its obtuse, sub- 

 -rotund leaves.
