NOTES ON THE FLORA OF SOUTHEASTERN CHINA

ONE TEXT FIGURE 
In continuation of my studies on the flora of southern China * 
the present contribution, like its predecessors, is based largely 
on Kwangtung material; I have included the descriptions of 
certain presumably new species from Fokien and Kwangsi Prov- 
inces. The paper is for the most part based on collections 
made for the Canton Christian College by Messrs. Levine, Mc- 
Clure, and Groff. A small but very interesting collection was 
received through the Canton Christian College from Prof. K. 
K. Ts’oong which has yielded a number of novelties, including 
new species in several genera not previously known to occur in 
China, and a representative of one family, the Dipterocarpa- 
ceae, hitherto unrecorded from China. Tung Sing, Boung Ching, 
near the boundary between Kwangtung and Tonkin, where many 
of Professor Ts’oong’s specimens were collected, is apparently a 
very interesting region from a botanical standpoint. In addition 
to the species proposed as new, totaling eighteen, in as many 
families, several previously described forms are recorded for the 
first time from Kwangtung Province. Ten genera are added to 
the list of those known from that province.
