and Protophytes await the future botanist’s attention. 
October 13th—Mr. Wm. T. Davis presented natural-sized 
drawings of leaf forms and fruit of the hybrid oaks found near 
Richmond Valley, with the following further remarks upon the 
same :— 
Since the September proceedings were printed, the oaks near 
Richmond Valley have been visited several times by Mr. Hollick, 
Mr. Gratacap and myself, and they have proved of so much interest 
that a detailed description of at least some of the trees may be 
worthy of record. 
Nineteen oaks have so far been discovered, each tree having a 
sort of individuality, and their consideration with a view to clear- 
ing up the mooted points is no easy matter, but one that will at 
least require an extended period of careful observation. 
Some leaves represent what has been considered as Quercus 
the mid-rib. The character and position of these oaks wou 
indicate that Q. phellos with Q. palustris are the parents and this 
In heterophylla the average diameter of the empty cups is about 
three m. m. more than palustris and the heighth of the nut is also 
greater in comparison to its breadth. In phellos the acorns are 
still smaller than in palustris, but it is an interesting fact that the 
roportions come closer to those of heterophylla. In Chambers, 
ncyclopædia it is stated that in hybrids “ valuable results are often | 
obtained as to size and abundance of fruit.”
