We now sought in this family among the species of which a full 
description was given, for that which corresponded in the largest 
number of most essential characters with Aptiana. We found that 
this was the case with Murya acuminata and we reproduce here a 
literal translation of this description, as given in our Mikrographie, 
but somewhat shortened for the reader’s convenience, by omitting all 
those characters of which no mention is made in the description of 
Aptiana. 
If the reader will compare the two descriptions with each other, 
he can judge for himself of the validity of Aptiana’s claim to be 
considered as a member of the family of the Vernstroemiaceae.

Annual rings, especialty in the sample 
most minutely examined, fairly distinct; 
0.35 mm to 2.5 mm thick. In several 
rings a period in the number of vessels 
and the transverse diameters of vessels, 
fibre-tracheids and wood parenchyma cells, 
in the 2 last named elements especially 
of the radial diameter; the maximum of 
this period about in the middle of the 
ring, the minimum in the outer lower

radial diameter of the fibre-tracheids. The 
limits of the rings sometimes more distinct, 
by the number of vessels in the different 
rings being unequal. On the limits of the
