SAND-BINDING PLANTS 



Certain plants have a natural capacity for growing in loose 

 sandy soils, or even in pure sand, as on barren sea-shores or river 

 banks. The value of such plants does not consist only in their 

 sand-binding properties, by which they prevent the erosion of land 

 or the shifting of sand-banks, etc., but also in establishing a foun- 

 dation in which it may be possible to introduce and grow more 

 useful plants. For sand-banks by the sea-shore, the following 

 plants are among the most adaptable : 



Calotropis gigantea; "Wara" S. A large glaucous shrub, 

 with large oblong leaves; common near sea coast in Ceylon. 



Canavalia obtusifolia. " Mudu-awara" vS. A creeping legu- 

 minous perennial, with bright-pink (sometimes white) flowers. 

 Grows on the sanely sea-shores. 



Spinifex squarrosus. "Water Pink," " Maharawana-rewula " 

 S. A grey or glaucous grass which grows in broad tufts on the 

 sandy sea-shores. It is especially cultivated on the Madras coast 

 for its sand-binding properties. 



Ipomoea biloba. "Mudu Bin-tamburu" S. A creeping plant 

 of the Convolvulus family, with bright purplish-rose flowers and 

 thick succulent leaves; common on the sea-shore sand along the 

 south and west coast of Ceylon. 



Scaevola Koenigii. A large glaucous bush, with yellowish 

 white flowers and pithy stems; common on the south-west coast of 

 Cevlon.
