ABSTRACT
MULYANINGSIH, TRI & RIDSDALE, COLIN ERNEST. 2004. An additional species of Villaria Rolfe
(Rubiaceae) from the Philippines. Reinwardtia 12 (2): 195 – 197. A new combination of Villaria Rolfe (Rubiaceae)
from the Philippines is described, based on Hypobathrum glomeratum (Bartl.) K. Schum. The character
combinations of stipules, bracts, bracteoles, calyx, ovary and placenta seen in this taxon are not found in
Hypobathrum but are known in Villaria.
Key words: Villaria, Hypobathrum glomeratum, Philippines

Villaria is a little known endemic
Rubiaceae genus from the Philippines, which
belongs to the tribe Hypobathreae. The Philippine
taxa of this tribe are little known and frequently
confused with "Randia" s.l. Villaria was proposed
by Rolfe in 1884. Surprisingly, at least two taxa
were originally earlier described by Blanco.
There appears to be a widespread, but poorly
collected taxon V. odorata (Blanco) Merr., which
is a coastal species. Further studies will probably
show that, V. rolfei Vidal. is synonymous with
this taxon. There are two further non coastal
species V. Philippineensis Rolfe from Cagayan,
Tayabas, Camarines on Luzon, and the little
known V. acutifolia (Elm.) Merr. from Davao,
Mindanao region. This current paper is concerned
with a new species of Villaria which has long
been confused and identified by Merrill (1918) as
a Hypobathrum.

4–5 mm by 8–9 mm, inside villous in the throat,
outside hirsute; lobes 5, ovate 1 mm by 1 mm;
style 1.5 mm long, terete, villous; stigma with 5-

flowers arranged in a compound verticillate

2 mm by 0.4 mm; fruits smooth, globose, 15 mm
by 15 mm, glabrous, exocarp thick, mesocarp
woody, endocarp membranaceous; stalk 6 mm by
0.7 mm, hirsute; seeds 5 - 11 per placenta,
lancinate, 2 mm long, 0.4 mm wide and 0.3 mm
thick.
VERNACULAR NAME. Caragli or caragri
(Tagalog).
DISTRIBUTION AND ECOLOGY. The species
was said to be found in the vegetation nearby
towns in Luzon, mentioned are Bataan, Bulacan,
Batangas and also Manila. It is strange that there
are no known recent collections from these areas
which were predominantly secondary vegetation
in the time of Merrill.
NOTES. This taxon has characters such as scales
and stipules pubescent on the inside. Bracts,
bracteoles and calyx densely pubescent on the
inside, calyx lobes rounded and ovary
monolocular with 2 parietal placenta, that are not
found in Hypobathrum Blume.
It is easily separable from other species of
Villaria by the narrowly elliptic leaves which are
pubescent below, particularly on the midrib and
veins.
