MATEKIALS FOE A FLORA OF FORMOSA. 169 



The present plant comes near V. bracteatum Thunb. from 

 ■which it is distinguishable by its more acuminate or even caudate 

 leaves and by its larger and glabrous calyx. Also near V. Carlesii 

 Dunn, and V, malaccense Wight ; 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. 0. Stapf. 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. 0. Stapf 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. ]\lerrill suggested 

 to me some years ago.
