AIZOACEAE 141 
low altitudes in the Philippines, growing especially in low places, 
ditches, etc., that are flooded during the rainy season. Ap- 
parently an introduced weed in the Archipelago. 
Illustrative specimen from Guadalupe, Rizal Province, Luzon, 
December, 1914 (Merrill: Species Blancoanae No. 724). 
Mollugo stricta Linn.; Blanco Fl. Filip. (1837) 52; ed, 2 (1845) 35; ed. 3, 
1 (1877) 64=MOLLUGO PENTAPHYLLA Linn. 
The Linnean species was correctly interpreted by Blanco, but 
it is a synonym of Mollugo pentaphylla Linn., which has priority. 
- Tilustrative specimen from Antipolo, Rizal Province, Luzon, 
October, 1913 (Merrill: Species Blancoanae No. 559). 
Mollugo subserrata Banco Fl. Filip. (1837) 51 (sp. nov.); ed. 2 (1845) 
34; ed. 3, 1 (1877) 63=MOLLUGO OPPOSITIFOLIA Linn. (M. sper- 
guia Linn.). 
- This species is of very wide distribution in the settled areas 
in the Philippines, growing in waste places in and about towns, 
fallow fields, old rice paddies ete. Fernandez-Villar reduced it 
to Mollugo stricta Linn., and I accepted this reduction in my 
previous consideration of Blanco’s species. Blanco’s descrip- 
tion, however, manifestly applies to Mollugo oppositifolia, not 
to M. stricta. 
Illustrative specimen from Taytay, Palawan, May, 1913 (Mer- 
rill: Species Blaneoanae No. 385). 
SESUVIUM Linnaeus 
SESUVIUM PORTULACASTRUM Linn.; Blanco Fl. Filip. (1837) 426; ed. ° 
2 (1845) 297; ed. 3, 2 (1878) 187. 
The Linnean species was correctly interpreted by Blanco. 
It is found along the seashore throughout the Philippines. 
Illustrative specimen from Taytay, Palawan, May, 1913 (Mer-
