OENOTHERACEAE 293 
This species is of very wide distribution in the Philippines, 
but I am inclined to retain Memecylon ovatum as a species dis- 
tinct from M. edule Roxb.; see Philip. Journ. Sci. 8 (1913) 
Bot. 215. 
Illustrative specimen from Taytay, Palawan, May, 1913 (Mer- 
rill: Species Blancoanae No. 581). 
MEMECYLON LANCEOLATUM Blanco FI. Filip. (1837) 301 (sp. nov.) ; 
ed. 2 (1845) 209; ed. 8, 2 (1878) 26. 
This species is common and widely distributed at low and 
medium altitudes in Luzon and is abundant in the regions from 
which Blanco secured most of his botanical material. Meme- 
cylon pyrifolium Presl, M. cumingianum Presl, and M. clausi- 
florum Naud., all based on Philippine material, are synonyms 
as I understand these forms as described; see Merrill in Philip. 
Journ. Sci. 8 (1913) Bot. 212. 
Illustrative specimens from Rizal Province, Luzon, November, 
1915, June, 1916, here known as colis or culis (Merrill: Spectes

OENOTHERACEAE 
JUSSIAEA Linnaeus 
Jussieua inclinata Blanco FI. Filip, (1837) 366, non Linn. f= Jussieua 
fluviatilis Blume; Blanco op. cit. ed. 2 (1845) 257; ed. 3, 2 (1878) 
114=JUSSIAEA REPENS Linn. 
The form that Blanco erroneously referred to Jussieua in- 
clinata Linn. f. in the first edition of his Flora de Filipinas, he 
correctly referred to J. fluviatilis Blume in the second edition. 
However, Blume’s species is a synonym of J. repens Linn. The 
species is widely distributed at low altitudes in the Philippines, 
growing on muddy banks and in shallow fresh water. 
Illustrative specimens from Lake Bay, Laguna Province,

Rizal Province, Luzon, November, 1915 (Merrill: neecie. Blan- 
coanae No. 921).

This species is common cad widely distributed in the Philip- 
pines at low altitudes in open wet places, possibly introduced.
