really a Hopea, or perhaps a Shorea, from the fact that the fruit 
is described as being “como en la especie plagata,” i. e., Hopea 
plagata (Blanco) Vid.

ELATINACEAE 
BERGIA Linnaeus 
Tillaea rubella Blanco FI. Filip. (1837) 75 (sp. nov.); ed. 2 (1845) 56; ed. 
3, 1 (1877) 106=BERGIA AMMANNIOIDES Roxb. 
In this reduction I follow Fernandez-Villar, for I can see no 
reason for distinguishing the Philippine form from the Asiatic 
one. The species is of very local occurrence in the Philippines, 
growing as a weed in old rice lands at low altitudes in Luzon. 
It is similar to Bergia serrata Blanco (B. glandulosa Turcz.), 
from which it is distinguished by its shorter pedicels, somewhat 
smaller, more crowded flowers, and usually 3 or 5 instead of 
10 stamens.

BERGIA SERRATA Blanco Fl. Filip. (1837) 3887 (sp. nov.) =Spergula 
serrata Blanco op. cit. ed. 2 (1845) 271 (nom. nov.) ; ed. 3, 2 (1878) 
140. 
The first name is the correct one, and the species is identical 
with Bergia glandulosa Turez. (1854), which was based on 
Cuming 1058 from Luzon. It differs from Bergia ammannioides 
Roxb., to which it is very closely allied, in its longer pedicels, 
somewhat larger flowers, and 10 instead of 3 to 5 stamens. 
Blanco’s description of the leaves as “sesiles, * * * abra- 
zando al tallo” is not good, but otherwise the description, habitat, 
and time of flowering apply perfectly to the species as here in- 
terpreted, while no other Philippine plant known to me has the 
characters indicated by Blanco for his species. It was reduced 
by Fernandez-Villar to Bergia verticillata Willd.—B. capensis 
Linn., a species unknown from the Philippines and one to which 
Blanco’s description does not apply. The species is widely dis- 
tributed in Luzon at low and medium altitudes, but is of local 
occurrence; it grows in dried out rice paddies and in other 
similar habitats. ‘
