Mentha
Notes
A native of the northern temperate countries, cultivated in Java. It never flowers and is propagated vegetatively.
CANTORIA l.c. examined the Philippine material of so-called M. arvensis and M. javanica phytochemically and came to the conclusion that all this was the same species which he referred to M. x cordifolia.
He stated, however, also that in the Philippine Menthas no flowers were ever found. This is not true as CONKLIN & BUWAYA PNH 79601 from the Mountain Prov. in Luzon, 1200 m alt. near an irrigation canal (vern.: amtin diolhan ietang), which I identified as M. arvensis var. javanica, is in flower; obviously it does not belong to M. x cordifolia.
