Abstract

---

The dry stream offers a variety of habitats depending on the avaibility of moisture and the extent of biotic disturbance. A greater proportion of the inhabiting plants comprises of the annual weeds of winter crops. The moist sites are invaded in early winter. After the winter rains , only the deep-rooted species survive along the water course . on raised and gravel- excavated sites, only those species thrive which either resist or evade drought . all the sites do not seem to differ much floristically .
