A. T. Hunz., L. acutiloba (Johnst.) A. T. Hunz. et Subils. and J. 
albiflora (Johnst.) A. T. Hunz. et Subils comb. nov.], and one 
Argentinian [/. /inifolia (Miers) Griseb.]. All the species have 
separate pollen grains. 
3. Revesia has four species also of xerophytic habitats: R. 
parviflora (Phil.) A. T. Hunz. in Argentina and Chile, and the 
three others in northern Chile [R. chilensis Gay, R. cactorum 
(Johnst.) D’Arcy, and R. juniperoides (Werd.) D’Arcy]. Revesia 
parviflora is reinstated as the correct name for the first species, 
because the type collection of Preroglossis laxa Miers belongs to 
R. chilensis. The only species with pollen grains in tetrads is R. 
parviflora.
