NOTES ON THE FLORA OF KWANGTUNG PROVINCE, CHINA 
By E. D. MERRILL* 
(From the Botanical Section of the Biological Laboratory, Bureau of 
Science, Manila, P. I.) 
Through the interest of Doctor Walter T. Swingle, of the 
United States Department of Agriculture, Washington, D. C., I 
was enabled to spend the period from October 13 to November 
9, 1916, in prosecuting field work in Kwangtung Province. 
Thanks to the courtesy of Mr. G. Weidman Groff, of the Canton 
Christian College, I was granted the facilities of that institution 
and made this the base of my field work. All collections were 
made on Honam Island, across the river from Canton, with the 
addition of one short trip, October 27 to 30, to Loh Fau Moun- 
tain (Lofaushan) in the country to the northeast of Canton. 
During the period spent in China, I collected about 600 numbers 
in all groups, and this collection presents a number of species 
previously unrecorded from China, or at least from Kwangtung 
Province, as well as some apparently undescribed forms. The 
present paper consists of the descriptions of these new species, 
and an enumeration of the additions to the Kwangtung flora, 
with a few references based on other collections, notably material 
secured by Mr. C. O. Levine of the Canton Christian College. 
In a few cases, where questions of nomenclature are involved, 
new combinations have been made. 
Hance? makes the following statement regarding the Kwang- 
tung flora: ; 
Six years ago the writer expressed the hope that he might shortly be 
able to give a complete list of all the plants which had been found in the 
province of Kwangtung. Further consideration, and especially the circum- 
stance that almost every short excursion from Canton or other cities where 
foreigners reside leads to the discovery of three or four new plants, has 
convinced him that such an enumeration would, after all, be too imperfect 
to be worth compiling; whilst the opening of several new ports, and the 
annually increasing facilities for penetrating into the interior of the Empire, 
encourage the hope that we may soon acquire a far better and more com- 
prehensive knowledge of one of the most interesting Floras which can 
occupy the attention of botanists.
