For. Bur. ^935 Curran, August, 1906, at base of limestone rocks. 
The first species of the genus to be reported from the Philippines, 
apparently allied to the Indian Teiicrium tomeniosnm Pleyne, judging from 
the description of that species. The specimens collected by Curran were 
distributed as Pogostettion, probably as Pogostemon nepetoidcs Stapf. 
Later, doubting the correctness of my determination, a duplicate was 
sent to Kew for comparison with Stapf*s type. The comparison was made 
by Mr. N. E. Brown, who reported that Curran's specimen was totally 
different from any Pogostemon in the Kew Herbarium. As there were no 
flowers on my retained specimen, no further attempt was made to determine 
it until it was rediscovered by Father Vanoverbergh. The two specimens 
cited manifestly represent the same species even though there are no 
flowers on Curran's specimen for comparison.
