Phyllody in accessory organs. In addition to the ordi- 

 nary organs of the plant, what are termed the acces- 

 sory organs, such as hairs, spines, &c., sometimes 

 become foliaceous. It is not to be wondered at that 

 spines, when they represent the framework of a leaf, 

 become sometimes clothed with cellular tissue, and 

 thus become indeed true leaves. This happens occa- 

 sionally in Berheris ; a similar thing occurs in the 

 stipules of some Leguminosce ; the scales of some 

 begonias ; the tendrils of Bignonia, Cohma, &c. 



The presence of two small green laminae on the 

 outer side of the two posterior stamens in Antirrhinum 

 ma jus has also been met with. The adventitious 

 organs appeared as if they were developments from 

 the thalamus a kind of fohaceous disc, in fact.
