SCROPHULARIACEAE 345 
A species fairly common in muddy places near tidal streams 
about Manila. Calytriplex obovata Ruiz & Pav. is generally 
cited as a synonym of Bacopa monniera, but Hooker f., Flora 
of British India 4 (1884) 272, states that it is very different 
from Herpestis monniera HBK.—Bacopa monniera Wettst.

LIMNOPHILA R. Brown 
Tala odorata Blanco Fl. Filip. (1837) 485. (gen. et sp. nov.); ed. 2 (1845) 
388; ed. 3, 2 (1878) 262=LIMNOPHILA RUGOSA (Roth) Merr. 
(Limnophila roxburghii G. Don). 
This species is the type of the genus Tala of Blanco and was 
reduced by Fernandez-Villar to Limnophila menthastrum Benth. 
I consider it, however, rather the same as L. roxburghii G. 
Don=- L. rugosa (Roth) Merr., at least the form of that species 
that has been credited to the Philippines. The generic name 
Tala is from one of the Tagalog names of this and allied species.

Diceros stoloniferus Blanco Fl. Filip. ed. 2 (1845) 349 (sp. nov.); ed. 3; 
2 (1878) 282=LIMNOPHILA STOLONIFERA (Blanco) comb. nov. 
Blanco’s species was reduced by Fernandez-Villar to Limno- 
phila repens Benth., a species not known from the Philippines 
but one to which Limnophila. stolonifera is apparently allied. 
In Index Kewensis the reduction is to Limnophila conferta 
Benth., a species also not known from the Philippines, and one 
very different from my interpretation of Blanco’s Diceros stolo- 
niferus. As I have interpreted Blanco’s species, and there is 
every reason to believe that this interpretation is correct, the 
species seems to be a valid one of Limnophila. Blanco’s speci- 
mens were from Guadalupe, near Manila, there known as oré- 
gano, but although I have been unable to find it in that locality, 
specimens from the neighborhood of Antipolo, also known as 
orégano, agree with Blanco’s description in all characters in- 
eluding habitat and time of flowering. _

This form, widely distributed in the Philippines, was reduced 
by Fernandez-Villar to Limnophila gratioloides R. Br. which is
