Gypothamnium and Oxyphyllum (Asteraceae) are two monotypic genera endemic to the Atacama Desert of northern Chile. We performed a phylogenetic analysis using published sequences of the plastid rbcL and ndhF genes, the trnL-trnF region and the nuclear ribosomal internal transcribed spacer (ITS) to assess the systematic placement of the two genera within Mutisioideae. On the basis of the phylogenetic results, we constructed area cladograms to explore the biogeographical relationships and origin of the genera. The phylogenetic analysis showed that Gypothamnium is closely related to Aphylloclados, Plazia, Urmenetia, Lycoseris and Onoseris, whereas Oxyphyllum is closely related to Leucheria, Moscharia, Polyachyrus and, with low support, Jungia. These results do not differ substantially from those proposed in previous treatments based on morphological characters. The biogeographical analysis suggests that Gypothamnium in the coastal Atacama Desert is related to taxa that are currently distributed in eastern subtropical South America and in the Puna. Oxyphyllum may have originated from central Chile and other areas in southern South America, but its sister group (Leucheria + Polyachyrus) also reaches the Puna and the coastal Atacama Desert. Both groups show ancestral affinities with elements currently distributed in north-western South America and Mesoamerica.

“…An isomer of dehydrodendrolasin (1) has been isolated from the nudibranch Ceratosoma brevicaudatum.l Trifolioside 11, a new acyclic sesquiterpene oligoglycoside, has been obtained from the pericarps of Sapindus trifoliatus,2 and gaillardoside has been found in extracts of Gaillardia coahuilen~is.~ A sesquiterpene glycoside, named loquatifolin A and derived from nerolidol, has been obtained from the leaves of Eriobotrya j a p o n i ~a . ~ Another substance of this type has been identified as a component of the aerial parts of Polyachyrus fus~us.~ The structures of artedouglasia oxides A (2), B (4), C (3), and D (5) have been elucidated. These sesquiterpenes have been isolated from the essential oil of Artemisia lactiniata.…”
