Abstract
We describe a distinctive subspecies of Galvezia leucantha from the island
of Santiago (San Salvador), Galapagos, Ecuador. The new subspecies, Galvezi
a leucantha subsp. porphyrantha Tye & H. Jager, is distinguished principall
y by its purple flowers and lack of pubescence. All three subspecies, and t
he species as a whole, have small and in some cases declining populations r
estricted to eroded scoria cliffs, and are considered Critically Endangered
(CR) by IUCN criteria.
