Baur, no. 8 (hb. Gr.). Endemic. None of the distinctions between 
this and P. galapageia, given by Bennett, hold in the series of speci- 
mens now at hand. Andersson names two foliar forms (latifolia and 
angustifolia), 
EUPHORBIACEAE.

A. Adamsii, nov. sp.; perennis; caule tenui plus minusve repente 
oplose ramoso fusco griseo-tomentuloso; indumento e pilis brevibus

centibus composito; foliis late ovatis vel suborbicularibus crenatis 
* With the material now at hand it is impossible to accept the treatment of 
oo given by Mueller Argovensis, who reduces all Galapageian forms to 
oe of one polymorphous species. We have here to do not only with annuals 
2 apa with erect and prostrate habit, and with leaves of very different 
a ea with pubescence varying from velvety and non-glandular to hirsute 
ce. but accompanying these considerable differences are others in the 
oc ce sufficiently striking and constant to be classed as specific distinctions. 
onowing key will suggest the leading diagnostic features.
