most remarkable circumstance is that the barks of trees so varying in 
leaf and flower as are doubtless the negrilla, the morada, and the 
naranjada, should so far resemble each other as to pass under the 
general name of Calisaya. But so it is;* and if the morada be at all 
allied to the C. purpurea, it must be Pies that, in the essential 
requisite of the bark-clothing, it differs widely from its Peruvian name- 
sake. The naranjada and "e Gf, indeed, plants in my possession 
turn out to be of these kinds), differ so widely in the leaves, that I 
shall not venture on their description here, except to remark that the 
naranjada has scrobicules not only at the axils of the veins, but also 
at their junction with the smaller veins, as in the Olea scrobiculata. 
To what possible cause, since imitation is excluded, can we ascribe 
that harmouy which, as Dr. Seemann has remarked, seems to prevail 
even in these obscure departments of vegetable physiology? The in- 
fluences of soil and climate would surely tell as soon upon the leaves 
as upon the bark, yet these darks assimilate, whilst the leaves do not.

The study of the vegetable fossils of the paleeozoic rocks presents a 
peeuliar interest on account of their singular forms, which generally 
separate them in a very remarkable manner from the plants now living 
on the earth. 
With the exception of the Ferns, which have a similar form through- 
out all time, the other plants of the coal period differ so greatly from 
those of the later periods, as well as those now living, that the most 
careful examination has failed to refer them to families of recent 
plants. 
However, since I began my researches, I have determined the affini- 
ties of several arborescent plants of this period to Eguisetacee and Ly- 
copodiacee.
