Abstract

Floristic analysis of regular and closed plantations of teak in Java showed a soil vegetation mainly of woody species. The rest was chiefly annuals. The short flora consisted of only a few species, never or only rarely seen outside the teak forest. Also recently introduced plants occurred and sometimes formed an important constituent. The regularity of the vegetation within each separate experimental plot and the decrease in the chance of development of introduced seeds in a closed soil vegetation made possible the occurrence of growth indicators for teak. These indicators seemed to be few. Climbing plants were limited chiefly by humidity. The large and woody species needed also certain physical soil conditions, and so, like the ferns, occur only in the better teak stands. The Amomum species depended on a favourable top soil and were restricted to soils allowing rapid and large growth of teak. In one region Gastrochilus (Zingiberaceae) occurred only in the better teak forests. Ophioglossum reticulatum indicated poor soil.
