Blake — Plants of Venezuela and Curacao 53 
interiores paullo tenuiores mucronibus saepissime rectis. Achenia 
2 mm. longa. Pappi corona 0.4 mm., cum aristo 1 mm. longa. — 
VENEZUELA: in sand dune valleys, Vela de Coro, 1 April 1917, 
Curran & Haman 440 (rypr in Gray Herb.) and 440A. 
Notwithstanding the remarkable character of the involucre, 
which is made up of coriaceous phyllaries somewhat united among 
themselves and to the receptacle so as almost to enclose the outer 
achenes, I believe that this very distinct new genus should be 
placed in the subtribe Verbesininae immediately before Spilanthes, 
with which it shows many marks of affinity.

ZUELA: Pedernales, 16 July 1917, Curran & Haman 1311 (TYPE 
in Gray Herb.). — Local name “ Escorbuto”’ (i.e., “ Scurvy ”’- 
plant). Rather distinct in appearance from typical S. urens Jacq., 
but without any difference which I can discover in essential 
characters.
