100 The Philippine Journal of Science i9n 
Since Hance’s time an enormous amount of botanical material 
has been collected in all parts of China, Forbes and Hemsley® 
enumerating 8,271 species for the area covered by their work. 
For the flora of Kwangtung Province, Dunn and Tutcher * have 
listed and made keys for about 2,550 species of flowering plants 
and ferns, giving the distribution, within the area, time of flower- 
ing, and color of the flowers for each species. This publication 
forms an excellent working basis for the flora of Kwangtung. 
The regions indicated by these authors on their accompanying 
map as botanically explored comprises but a small percentage of 
the entire area of the province, and these areas are chiefly in the 
more accessible regions. They state in their summary of desid- 
erata that it is desirable to explore not only the unknown areas, 
but also indicate the necessity of an investigation of the more 
accessible parts. The additions to the Kwangtung flora in the 
present paper are all from areas that have been fairly exhaus- 
tively explored, so it is evident that intensive field work in 
almost any part of Kwangtung Province may be expected to 
yield additions to the known flora, while an exploration of the 
vast botanically unexplored areas will certainly yield not only 
additions in the nature of already described species, but may be 
expected to yield a fair number of undescribed forms. The 
material collected by me adds several hundred localities to Dunn 
and Tutcher’s list, but it has not been considered worth while to 
enumerate these here.
