MATERIALS FOR A FLORA OF FORMOSA. 169 
The present plant comes near V. bracteatum Tuuns. from 
which it is distinguishable by its more acuminate or even caudate 
leaves and by its larger and glabrous calyx. Also near V. Carlesii 
Duyn, and V, malaccense Wicut ; but differs from the former in hav- 
ing leaves, obtusely serrulate on the margin, more or less acute at the 
base, and from the latter in having glabrous calyx.

After the publication of my paper above mentioned, my atten- 
tion was called, by Mr. E. D. Merrill of the Bureau of Science, P.I., 
to a Bornean species described by Dr. O. Starr. At that time, I 
could not compare my plant with the named species, as there was 
nothing of the Borneoan collection in the Tokyo Herbarium, nor is 
the paper of Dr. O. Starr accessible to me. Since coming to Kew, 
I have compared my plant with the type of the same species, and 
found that they are exactly identical, as Mr. E. D. Merrill suggested 
to me some years ago.
