he paper is in support of the views recently eR i the author 
that the spike in Sandal is caused by insufficiency of water owing to rela-

al solution must be based on (1) experimental proof; (2) evi- 
dence of a chemical nature; (3) physiological anatomy of the leaf. 
An outline of the third aspect is presented in brief and the discus- 
osmotic pressure. The condensation of starch is connected with the 
osmotic gradient prevelling t in the leaf. The rapidity of growth in spiked 
twigs is also explained. : :
