Argentina
Herbarium studies, primarily at Smirniguy Tucuman (Instituto Lillo), Buenos Aires, La Plata and Santiago, necessary for completion of a monograph on the role of geographic and genetic isolation and on the influence of polymorphism and transAndine migration as shown by the distribution and relationships of the Argentine-Chilean species of Nicotiana and related genera Patunia, Castrum and Fabiana.
Chile
Evidence of major and relatively recent climatic alteration in north central Chile is seen in the presence of a few restricted areas in its semi-desert containing depauperate but otherwise characteristic species peculiar to the Chilean temperate rain forest some 600 miles to the south. That there was, similarly, retreat of a subantarctic vegetation from southern Chile is suggested by preliminary determination of the presence of species of subantarctic origin in the isolated, unique and previously little known flora of the Cordillera Pelada in Prov. Valdivia (41°S). To verify the presence of a subantarctic element in the evolution of the coastal floras of Chile the relation of the Cordillera Pelada flora to the composition of the surrounding temperate rain forest will be intensively studied.
Peru
In 1942-43 collections were made of the largely unknown vegetation on the altiplano of northwestern Dept. Puno from the Cordillera Carabaya eastward to the Rio Inhambari. The evidence obtained points to relationships between species of that Peruvian altiplano and those of the better known altiplano of adjacent Bolivia. It suggests that the role of high plateaus established prior to recent vertical uplift as ancient pathways of transAndine plant dispersal. Additional collecting in Dept. Puno will be carried on to permit more complete comparison of the two floras involved.
All field data will be vouchered by herbarium material and photographs. Where possible duplicate herbarium material will be obtained for distribution to South American and North American herbaria and to specialists concerned with South American plant taxonomy and phytogeography.
As in the past, assistance in carrying on the proposed field work will be made available through the cooperation of the governments of the three Republics and other institutions and agencies.
