MERRILL AND ROLFE. 
ill age, glabrous, somewhat shining above, entire, the base acute, the 
apex gradually and sharply acuminate, 2.5 to 5 cm long, 5 to 8 mm wide, 
subsessile, the nerves rather obscure. Panicles 15 cm long or less, slightly 
pubescent, densely ferruginous-tomentose at the base only, diffuse. 
Female flowers sessile or short-pedicellate, 1.5 mm long or less, the bracts 
deciduous, the sepals about 1.5 mm long. Ovary subglobose; style 2-cleft. 
Male flowers pedicelled, the bracts if any early deciduous. Stamens 
3 ; anthers 2 mm long, the filaments very short. Drupe about 5 mm long, 
slightly longer than broad and somewhat compressed, rugose when dry.

An interesting species, the first representative of the genus to be reported from 
the Philipjnnes, well characterized by its comparatively narrow leaflets and 
2-cleft styles.

This species must be excluded from the known Philippine flora, as of the- 
specimens cited by Perkins 1. c., Cuming 2330 is from Malacca, correctly localized 
in Engler’s monograph of the family, 2 while Merrill 610 from Culion is Buchan-

Blanco’s Paliurus Dao was referred by F.-Villar to Dracontomelum mangiferum 
Blume, in which he was followed by later authors, but the Philippine material 
on comparison with authentic specimens of Blume’s species was found to differ 
constantly from D. mangiferum in its much smaller leaflets. Blanco’s specific 
name is here retained for the Philippine form, for although his description is 
short and rather imperfect it manifestly applies to the specimens here cited. 
Engler 3 has referred Poupartia pinna t a Blanco to Dracontomelum mangiferum 
Blume, but it seems probable that Poupartia pinnata Blanco is really referable 
to Spondias mangifera Willd. Dracontomelum celebicum Koorders, from Celebes, 
is apparently identical with the form here considered, so far as can be determined 
from the fragmentary cotype in Herb. Kew. Dracontomelum Dao seems to be 
more closely allied to D. sinense Stapf than to D. mangiferum Blume. The species 
is remarkable for its strongly developed buttresses. It is commonly known to the 
natives of the Philippines as dao. The wood is rather soft and of little value.
