SAPOTACEAE 301 
Iilustrative specimens from Antipolo, Rizal Province, Luzon, 
December, 1914, June, 1915 (Merrill: Species Blancoanae Nos. 
662, 934). 
PALAQUIUM LANCEOLATUM Blanco FI. Filip. (1837) 408 (sp. nov.) ; ed. 
2 (1845) 282; ed. 3, 2 (1878) 159. 
Blanco’s species is apparently a valid one, but my first attempt 
to interpret it, Govt. Lab. Publ. (Philip.) 6 (1904) 15, was 
wrong, and the form I then referred to it Dubard has very cor- 
rectly separated as a distinct species, Palaquium merrillii 
Dubard. But two collections, conforming to Blanco’s descrip- 
tion, have been received, and from this material Palaquium lan- 
ceolatum Blanco has been redescribed by me, Philip. Journ. Sci. 
10 (1915) Bot. 62. Palaquium lanceotatum Blanco is the type 
of the genus. 
ACHRAS Linnaeus 
ACHRAS SAPOTA Linn.; Blanco Fl. Filip. (1837) 236; ed. 2 (1845) 165; 
ed. 3, 1 (1877) 298, t. 85. 
The Linnean species was correctly interpreted by Blanco. It 
was introduced into the Philippines at an early date by the 
Spaniards and now is found in cultivation throughout the Archi- 
pelago; it is universally known as chico.

LUCUMA Jussieu 
Achras lucuma Blanco FI. Filip. (1837) 237; ed. 2 (1845) 166; ed. 3, 1 
_ (1877) 299, t. 297, non Ruiz & Pav. =LUCUMA MAMMOSA (Linn.) 
Gaertn. 
This Mexican species was introduced into the Philippines by 
the Spaniards at an early date, but is now found in cultivation 
only sparingly and very locally. The fruits rarely enter the 
Manila market. It is known as chico-mamey. , 
Illustrative specimen from Maragondong, Cavite Province, 
bard October, 1914 (Merrill: Species Blancoanae No. 54). 
SIDEROXYLON: Linnaeus 
SIDEROXYLON DUCLITAN Blanco Fi. Filip. (1887) 129 (sp. nov.) 3 ed. 
2 (1845) 92; ed. 3, 1 (1877) 168. 
Sideroxylon balitbitan Blanco FI. Filip. (1837) 130 (sp. nov.) ; ed. 2 (1845) 
92; ed. 3, 1 (1877) 169=SIDEROXYLON DUCLITAN Blanco. 
There is no reason whatever for attempting to distinguish 
Sideroxylon balitbitan as a species distinct from Sideroxylon 
~ 
duclitan Blanco. Blanco’s whole description consists merely of — 
the statement that the leaves are wider than those of duclitan, ~
