STOMATA ON THE BUD SCALES OF ABIES PECTINATA. 
In the Metaspermz stomata occur on all normal leaves. They are 
also usually found on all of their well developed bud scales. 
The needle like leaves of 
the Coniferze are smaller, 
and hence have fewer sto- 
mata than the leaves of the 
Metasperme. On this 
account one would expect to 
find fewer or no stomata on 
their morphological equiv- 
alents, the bud scales. This 
occur on the bud scales of 
the Conifer. 
Griiss* says that stomata 
are never present on the bud 
scales of the Conifere. 
Schumann? makes the same 
statement. In a recent
