This species seems to be widespread in the southern islands. The following 
are given as vernacular names: baia (Foxworthy) ; bacaue (Mangubat) ; bucao 
(Hutchinson) ; wsiu, bolocaui (Merritt). Copeland’s specimens have fruit which 
is very interesting in structure. The caryopsis is globose, black, smooth, 3.5 
mm in diameter, tipped with the style and 3-lobed stigma, and supported at the” 
base by the persistent glumes. The pericarp is easily separated and the scutellum 
of the seed is apparently a thin gelatinous film enclosing the embryo and half 
of the endosperm and semi-adherent to the pericarp.

Local investigation, including especially an examination of the mature culms, 
the culm-sheaths, and the ripe fruit, may show this to be a species distinct 
from Dinochloa scandens. Borden gives the vernacular name as timac; Merrill 
and Merritt give it as usiu.
