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 Berberis; a similar thing occurs in the 
stipules of some Leguminose; the scales of some 
begonias ; the tendrils of Bignonia, Cobea, &e. 
The presence of two small green lamine on the 
outer side of the two posterior stamens in Antirrhinum 
majus has also been met with. The adventitious 
organs appeared as if they were developments from 
the thalamus—a kind of foliaceous disc, in fact.
