358 SPECIES BLANCOANAE 
settled areas of the Philippines at low and medium altitudes. It 
occurs especially in gardens, and in waste places in and about 
towns, and is undoubtedly an introduced weed in the Archi- 
pelago. The Linnean specific name biflora has priority over the 
more commonly used paniculata; as to their identity, with critical 
notes on nomenclature, see Trimen. Fl. Ceylon 2 (1894) 317.

Oldenlandia capensis Blanco Fl. Filip. (1837) 62; ed. 2 (1845) 45; ed. 
8, 1 (1877) 83, non Linn. f.=OLDENLANDIA DIFFUSA (Willd.) 
Roxb. 
This species is found in and about towns throughout the Phil- 
ippines, at low altitudes, and is probably an introduced plant 
in the Archipelago. It grows in gardens, on damp walls, and 
in waste places, but is nowhere very abundant. 
Illustrative specimen from San Antonio, Laguna Province, 
Luzon, October, 1915 (Merrill: Species Blancoanae No. 985). 
Oldenlandia affinis Blanco Fl. Filip. ed. 2 (1845) 44; ed. 3, 1 (1877) 83, 
non DC.=OLDENLANDIA CORYMBOSA Linn. 
Blanco’s description is not good for Oldenlandia corymbosa 
Linn., yet better fits this species than any other form known 
from the Philippines. Fernandez-Villar was certainly in error 
in reducing it to Oldenlandia nudicaulis Roth [=O. ovatifolia 
(Cav.) DC.], for Blanco describes a very different plant. 
Oldenlandia corymbosa Linn. is common and widely distributed 
in the settled areas of the Philippines at low and medium 
altitudes.

The plant described is apparently the same as de Candolle’s 
species, which was based on specimens originating in Sorsogon 
Province, Luzon. Fernandez-Villar reduced Hydrocotyle mono- | ¥ 
petala to Epithema, of the Gesneriaceae, as a valid species, 
Epithema triandrum (Blanco) F.-Vill., but nothing in Blanco’s 
description applies to this genus or family. I have very little 
doubt that the form Blanco observed is nothing but Ophiorrhiza 
oblongifolia DC., with the flower, as to its stamens, erroneously _
