PHILIPPINE PALMS, I. 
231 
Mindanao, District of Zamboanga; San Ramon, collected by E. B. Copeland 
with full grown male flowers and unripe fruit March 16, 1906. Vernacular 
name in Chapocano “Cabonegro” and in Moro “Ambung.” 
The collector’s “field notes” state that the plant which supplied the specimen 
had a trunk 1 m. high and 30 cm. in diameter, adding, however, that it “becomes 
a tree” and that it is “a source of sago” as is the case with its near ally 
A. undulatifolia Becc. 2 from which it differs in the shape of the male flowers, 
these being oblong with a round top in A. imdulatifolia, ovoid and suddenly 
apiculate in A. Ambong ; furthermore the stamens in the latter are 100, while in 
the former they are about 150; the stem of A. undulatifolia is taller and thinner, 
and the leaflets at their base have two auricles one on each margin instead of 
one, otherwise the leaflets are extremely alike in the two species. 
The leaves of young plants of A. Ambong in their terminal part have a 
striking resemblance to those of Wallichia oblongifolia Griff., to which I had 3 
doubtfully referred a sterile and very incomplete specimen collected also at 
Zamboanga by R. Garcia, No. 653 Ahern. In A. Ambong the scars of the fallen 
male flowers are orbicular, about 6 mm. in diameter and show the punetiform 
marks of 10-12 fibro-vascular bundles; in A. undulatifolia there is at least double 
that number of these marks and this fact is apparently in correlation with the 
more numerous stamens in the latter species.

40—50 cm. longis et apice quam centralibus profundius divisis ; divisio- 
nibus longe acuminato-setiferis. Spadix, gracilis elongatus, parte axili 
subteretei digiti minoris crassitiae; inflorescentiis partialibus pluribus, 
duplicate ramosis, ramulis floriferis 3—5 cm. longis, 1 mm. crassis. Fruc-

A tall species. Stem slender, 20 m. high and 20 cm. in diameter 
{Curran). Leaves forming an almost complete multifid circle; the 
petiole long and slender, 3 cm. broad in its basal part, where it is flattish 
above and convex beneath and with the margins acute and very closely 
armed with small horizontal conical-dentiform spines of which the largest 
are 5-6 mm. long, usually straight, horizontal and occasionally retrorse; 
higher up the spines gradually become smaller and more scattered and
