DISTINCTIVE CHARACTERS OF QUERCUS AND CASTANEA. 183 
In conclusion, I may say that I entirely concur with Dr. Lindley in 
regarding Juglandacee as the nearest direct allies of Corylacez. ‘That 
eminent botanist adduces the lobed and wrinkled cotyledons of certain 
Oaks in proof of this affinity ; and I may add that were the sinuosi- 
ties of the seed of the common Walnut closed,—in other words, were 
their sides pressed together,—it would exhibit some analogy with that 
of Fagus, the plication being dorsal, however, instead of facial. A 
direct proof of this relationship is furnished by a fine new Oak de- 
tected by me last summer in the Hongkong woods (Q. Zrwinii, mihi), 
the branchlets and leaves of which abound in a pleasant, fragrant, re- 
-sinous juice, so that the latter, which are naturally opaque, appear as 
if varnished when prepared for the herbarium by washing over with a 
spirituous solution of bichloride of mercury. And a comparison of 
with the same organs in Carpinus, will, I think, place this affinity in 
a still clearer light. Had Poeppig’s Fagus glutinosa belonged to the 
B 
genus to which that traveller referred it, it would by its pinnate leaves 
have furnished an additional link of connection; but his plant was 
long ago ascertained by Mr. Miers to be a species of Eueryphia, since 
published by M. Claude Gay under the name of Æ. pinnatifolia. ` 
Were I more favourably located, with access to extensive herbaria 
and libraries, I have no doubt that I might have ilustrated and en- 
forced the arguments adduced above by examples both more nume- 
rous and more striking; but T trust I may plead my habitat, “ in ul- 
timo fere orbis angulo," to use the words of Thunberg, and with 
nothing but my own library and herbarium to fall back on, as some 
excuse for whatever defects or oversights may be observed in this paper.
