The difference which the concepts of the phytoclimates of the arctic and antarctic chamaephytes suggest to us

Abstract

The authors comment Raunkiaer?s concept of the phytoclimate of the chamaephytes. Attention was also directed to the problem of the biogeographical limits, especially where referring to the southern part of South America and the Antarctic in general. Furthermore a geographical and climatological sketch of the Antarctic and the surrounding territories is added. The conclusion is reached, that Raunkiaer?s concept can not be accepted in its austral limitation, having used here elements, corresponding to the plant communities of the insular cordon, which latter ones belong, according to the authors, to the subantartics. After manifesting their opinions on Raunkiaer?s concept of the phytoclimate of the antarctic chamaephytes, they show by means of a map the natural provinces and fix the new limits of the phytoclimate of the Malvinas, Staten-Island, Fireland, Picton, Navarino, etc. which should be included into the cooltemperate climatological province and therefore can not be called subantarctic.
