44 Present State of the Genus Cinchona. 
commerce; growing together, Pavon says, and often 
coming together (sometimes intermingled) to the English 
market; but, though so nearly allied, not confused by 
insensible transition.* 
Cinchona officinalis, 8. crispa—This form of Loja bark 
was described and named by Tafalla as Czxchona crispa, 
and is described by Mr. Howard under that head in his 
“Quinologia.” Nevertheless it is his opinion that it is so 
manifestly one of the forms of the Loja bark as to be 
best looked upon as above. It is the Quzna crespilla, or 
carrasquena of the older botanists, and the Quzna fina de 
Loa of modern trade. 
The plant was found growing by Cross ina deposit of 
peat on the summit of the highest mountains (the Sierra 
Grande) around Loja. These Loja barks are adapted to 
grow on the roughest and most elevated portions of the 
Neilgherries, and also to flourish in Ceylon, and, beyond 
other sorts, to bear well the climate of the sub-Himalayan 
ranges, and there can be little doubt of their successful and 
profitable cultivation. 
Dr. Seemann found the plant at a lower elevation, and 
excellent specimens were brought back by both these 
travellers, including the bark, concerning the source of 
which, therefore, no doubt can remain. 
It is to be regretted that from the present confusion of 
nomenclature in India, it is difficult to ascertain what is 
meant by the descriptive terms there applied to the barks. 
If the above arrangement could be admitted, it would 
greatly simplify the matter, and be practically useful in its 
results. 
Mr. Howard proceeds to a review of the grey barks of 
Huanuco, the red barks of Ecuador, the Pitayo barks of 
Popayan, and the lancifolia barks of New Granada, which 
will be published in the Proceedings of the Congress, and 
directs attention to the spelling of the name CINCHONA, or 
CHINCHONA, and to the allied genus CASCARILLA, or, as 
called by the Germans, LADENBERGIA. Nothing would 
tend so well to settle these questions as the expression of 
opinion at a botanical congress. 
In conclusion, the writer expresses his. opinion, that every 
* Darwin has shown, in an able paper communicated to the 
Linnean Society on another family of plants, that the form of the 
flower is either entirely macho, or entirely hembra, not passing 
from one into the other.
