both syntype collections. Chile: Copiap6, Gay (G, also photo- 
graph 23087, Field Museum series; P; NY); Coquimbo, Gaudi- 
chaud 83, 1835 (FI); the specimen collected by Gay (P) has 
been chosen by us as lectotype.—Heuser, Spores of Chile 58, 
pl. 54 (f. 626). 1971. Description of the pollen grains. 
Besides the characters mentioned in the key, this species is very 
easily recognized by its xeromorphism: its stems are almost leaf- 
less, or with small linear-elliptic sessile leaves, (2) 4-8 (9) mm long 
and scarcely | mm in width. It inhabits the Chilean deserts of 
Atacama and Coquimbo provinces (ca. 700-2800 m alt.); the 
boreal limit of its area is uncertain, because of the scarcity of 
materials at hand. For this reason, we have inserted a question 
mark (PI. I, 1) in the vicinity of the Tropic of Capricorn, which, 
most probably, is passed by this species.
