A rare endemic species of the peculiar “lomas” type of vegeta- 
tion, found at the desertic Pacific coast in southern Peru, from 
Arequipa to Tacna; it is closely related to L. schwencktoides, and 
even more to L. /omana and L. acutiloba. These last two species 
are sympatric with L. Darcvana, differing in their herbaceous 
ephemeral stems, with two types of leaves: basal petiolate leaves 
(at congested internodes), and sessile cauline ones at the remain- 
ing upper nodes. L. schwenckioides, on the other hand, grows at 
higher elevations in central and northwestern Peru, showing 
taller stems, and its pubescence lacks any sort of branched hairs.
