more squarrose. The E. amhigua^ De Cand,, L c- p- 295, no. 5, of Avliich I have seen an original specimen 
cultivated in the Berlin Botanic Garden, seems also to belong to this variable species, 
608. Gynoxys Cumingii^ Bcnth. in Orstcd Composit^e Centre- Amcricansej p. 43. no- 176 (1853). 
Common about Panama. 
A beautiful species, having the largest flower-heads of all species of the section Seandentes hitherto 
known. Our specimens accord with Mr. Bentham's diagnosis, 1. c. It is however nearly allied to another 
new species, gathered by Moritz in the province of TrujiUo, and described by C. H. ScMiltz Bip. under the 
name of Gynoxys avriculafa, "which is well distinguished by the broad and rounded amplcxicaul base of the 
suddenly angustate and contracted petiole, by the somewhat smaller, though large capitula, and by the not 
canescent involucre. G. Cumingii, Benth., has the petioles not at all auriculate at their base. The habit is 
the same in both.
