Euphorbia (Cytfarospermum) Cofradiana. Annual, erect, 
branching, 2-3 dm. high, slightly pubescent; upper leaves oppo- 
site, broadly ovate, rounded at the tip, cuneate at base, setulose 
on both surfaces, paler beneath, the larger 3 cm. long, nearly as 
wide, on petioles twice as long, those from the short axillary 
branches much smaller; flowers axillary, solitary, on pedicels 5 
mm. long; involucres turbinate, less than 1 mm. high, setulose, 
the short lobes linear-lanceolate, lacerate; glands 5, each with 4 
finger-like appendages; styles divided and distinct to the base; 
capsule setulose, 1.5 mm, in width: seed orbicular, pitted with 
numerous crater-like depressions. 
Collected at Cofradia. This species isnear £. calicola Fernald, 
but is not ‘‘viscid-setulose with long pale hairs,’’ the involucre is 
turbinate instead of campanulate, the flowers are on much shorter 
pedicels and there are other minute differences. From £. astrottes 
it seems also to be distinct.
