xv, 3 Merrill: Notes on the Kwangtung Flora 227 
retained in Manila; one was sent to Dr. A. Chevalier, director 
of the Institut Scientifique in Saigon, Indo-China; one to the 
Canton Christian College, Canton, China; one to the library of 
the United States Department of Agriculture, Washington; one 
to the British Museum (Natural History), London; and one 
to the Museum d’Hisfoire Naturelie, Paris. The essential object 
in preparing this manuscript was to establish a basis for further 
investigations regarding the status of Loureiro’s species, as there 
still remains a high percentage of forms that are unintelligible 
from the descriptions alone. Eventually, when we shall have 
secured sufficient additional data to warrant doing so, it is hoped 
that a critical revision of Loureiro’s species may be prepared 
and published. 
The manuscript mentioned above summarizes in convenient 
form all the data at present available regarding the status of 
Loureiro’s species in relation to those described by other authors, 
and from it can be determined those that are definitely known 
and those that are of a more or less doubtful status. Fourteen 
genera have not definitely been placed, of which twelve have not 
been referred to their proper families, while about three hundred 
seventy-five species are still more or less doubtful, and cannot, 
from the description alone, be safely correlated with those of 
other authors. Of these doubtful species many cannot be re- 
ferred to their proper genera, and nearly fifty cannot be even 
referred to their proper families. Any great reduction in this 
rather high percentage of doubtful species cannot be expected 
until intensive field work shall have been prosecuted, with spe- 
cial reference to the problem, in southern China but more es- 
pecially in Cochin China, in the vicinity of Hue where Loureiro 
resided.
