Fourtli, that these adventitious shoots did not liave the 

 normal leaf arrangement. The leaves were not transversely 

 })laeed but perpendicularly and that the leaves were not of the 

 same size. The anisophylly was well niarked the lower leaf 

 being the larger.

 increased. While other writers found the production on a few 

 individuals. Küster found in the case oi An ag all is coerulea and 

 Linaria Cymhalaria that every wounded individual produced 

 one or more such hypocotyl buds. There was no fixed law as 

 to place of origin in the hypocotyl. 



Küster^) further confirmed the previous observations in 

 regard to anisophylly. Experiments aimed to determine the 

 cause of this phenomenon were not successful.
