| Abstract: | Eupatorium leonardii, presently known only from Mt. Mingan in the border region between Aurora and Nueva Ecija Provinces in Luzon, Philippines, is described and illustrated. The new species is remarkable because it is the only woody representative of the genus with a peculiar spiral phyllotaxy. Previously, Eupatorium s. str. consisted of herbs with opposite or verticillate phyllotaxy. |
