OMPHALEA Linnaeus 
Tragia bracteata Blanco Fl. Filip. ed. 2 (1845) 480 (sp. nov.); ed. 3, 3 
(1879) 94=OMPHALEA BRACTEATA (Blanco) comb. nov. (Ompha- 
lea philippinensis Merr.). 
Blanco’s species was erroneously reduced by Fernandez-Villar 
to Pimeleodendron amboinicum Hassk., with which Blanco’s de- 
scription does not conform in any particular; no representative 
of Pimeleodendron is known from the Philippines. The descrip- 
tion of Tragia bracteata Blanco conforms very closely with the 
characters of Omphalea philippinensis Merr., and I have no 
hesitation in substituting Blanco’s specific name for the one 
I proposed for this form.

EXCOECARIA Linnaeus 
EXCOECARIA AGALLOCHA Linn.; Blanco Fl. Filip. (1837) 786; ed. 2 
(1845) 541; ed. 3, 3 (1879) 193. 
The Linnean species was correctly interpreted by Blanco. It 
is common along the seashore throughout the Philippines.

HOMALANTHUS Jussieu 
' Excoecaria laevis Blanco Fl. Filip. (1837) 788 (sp. nov.); ed. 2 (1845) 
548; ed. 3, 3 (1879) 194=HOMALANTHUS POPULNEUS (Geisel.) 
Pax, var. LAEVIS (Blanco) Merr. comb. nov. [Homalanthus populneus 
(Geisel.) Pax, var. siccus Pax (non Excoecaria sicca Blanco) ; Carum- 
bium populneum var. minus Muell. -Arg. in DC. Prodr. 157 (1866) 
1145]. 
This species is common and widely distributed in the Philip- _ 
pines at low and medium altitudes. It is one of the character- | 
istic plants appearing in recently cleared areas that are allowed © 
to revert from cultivation. Blanco’s specific name is here 
adopted as the varietal one as it is older than the varietal name 
proposed by J. Mueller, while Pax was entirely wrong in adopt- 
ing the varietal name siccus from Blanco’s Excoecaria sicca, as 
Excoecaria sicca Blanco is Alehornea sicca (Blanco) Merr., not 
at all Homalanthus; see page 224,
