a distinct genus of the Onagraceae by Fernandez

COMPOSITAE
a distinct genus of the Onagraceae by Fernandez-Villar, but by
Bentham and Hooker and by Engler and Prantl it was referred
with doubt to the genus Erythropalum of the Olacaceae. It is
not uncommon in fallow rice lands about Manila.
Illustrative specimen from Antipolo, Rizal Province, Luzon,
October, 1913 (Merrill: Species Blancoanae No. 548).

To Eupatorium luzoniense Llanos referred, with doubt, Eupa­
torium ayapana Vent., as described by Blanco, but this is a
manifest error. Eupatorium ayapana Vent.—E. triplinerve
Vahl was correctly interpreted by Blanco; it occurs in the
Philippines only as a very rarely cultivated plant and is
thoroughly well known to the few who cultivate it. Llanos
states, regarding his Eupatorium luzoniense: "No es conocido,
y es frecuente a orilla de los caminos y huertos de los naturales.
El estigma parece de las vernonias." Vernonia cinerea Less,
is very common along streets and paths and as a weed in gardens,
growing at low and medium altitudes in the settled areas
throughout the Philippines; moreover Llanos's description cer­
tainly applies to Lessing's species.

This species is common and widely distributed in the settled
areas of the Philippines at low altitudes, certainly introduced.
