EUPHORBIACEAE 221 
Blanco’s description applies perfectly to the form I described 
as Claoxylon elongatum, and:I have not the slightest hesitation 
in substituting Blanco’s specific name. Fernandez-Villar was 
entirely wrong in referring it to Alchornea blumeana Muell.- 
Arg., a species that does not extend to the Philippines, and one 
to which Blanco’s description does not at all conform. It is to 
be noted that Pax & K. Hoffman, Engl. Pflanzenreich 63 (1914) 
112, have confused Claoxylon elongatum Merr. and C. arborewm 
Elm. and have referred the type and only specimen cited in 
the original description of the latter to Claorylon pedicellare 
Pax & K. Hoffm. ;

DORYXYLON Zollinger 
(Sumbavia Baillon) 
Adelia acidoton Blanco Fl. Filip. (1837) 815; ed. 2 (1845) 562; ed. 3, 3 
(1879) 226, t. 463, non Linn.=DORYXYLON SPINOSUM Zoll. (Suwm- 
bavia rottleroides Baill.). 
This species is of local occurrence in Luzon, being known from 
Union, Pangasinan, Pampanga, Nueva Ecija, Bulacan, Rizal, 
and Laguna Provinces, Luzon, but from no other parts of the 
Philippines. Sumbavia rottleroides Baill. has been the gen- 
erally used name for the species, but this is antedated by Doryxy- 
lon spinosum Zoll., and the case does not appear in the lists of 
nomina conservanda adopted by the Vienna and Brussels Bot- 
anical Congresses. The synonymy is as follows: 
-DORYXYLON SPINOSUM Zoll. in Nat. Tijdschr. Nederl. Ind. 14 (1857) 
152. 
Adelia acidoton Blanco Fl. Filip. (1837) 815, non Linn. 
Sumbavia rottleroides Baill. Etud. Gén. Euphorb. (1858) 390. 
Mercadoa mandalojonensis Naves in Blanco Fl. Filip. ed. 3 (1877-83) 
t. 468; F.-Vill. Novis. App. (1880) 193 in syn. sub. Sumbavia rottle- 
roides Baill.
