That group of plants capable of growth and reproduction at temperatures high above the normal or ordinary has long been an object of interest and study among scientists. An examination of any systematic treatise on the Schizophyceae will be rewarded by a considerable list of species that grow in hot springs, etc. In Rabenhorst's "Flora Europa Algarum" for instance, there are no fewer than thirteen genera having species or varieties characterized as "thermalis," while others are known to live in water having a temperature of 80°-93° C. Conspicuous and abundant as the Schizophyceae are in these thermal waters, yet they are accompanied by many less conspicuous forms, the Bacteria, Schizomycetes. These have been discovered and described only since the introduction of modern laboratory technique.
