Seedling Anatomy of Certain Sympetalae . 
Antirrhinum Orontium , L., differs from Linar ia externally only in 
the larger size of the seedlings and the slight inequality of the cotyledons. 
The region of transition is, on the whole, rather shorter ; in the root the 
xylem plate is quite inconspicuous. 
Scrophularia nodosa, L., in all essentials resembles Linar ia origanifolia. 
In the petiole the xylem elements are arranged in a single row parallel 
with the upper surface of the leaf, while the diarch plate also consists 
of a single row of elements, but arranged in the cotyledonary plane.

Mimulus hiteus , L. Apart from the presence of a cotyledonary tube,
