PHILIiriNE PALMS, T. 231 
Mindanao, Dislriet of Zaiiiboanga ; San Ramon, collected by IL li. Gopelond 
with full grown male flowers and unripe fruit March 16, lUUO. Vernacular 
name in Chapocano ''Cahonegro" and in Moro ^'Amhufiff." 
The collector's "field notes" state lliat the plant which supplied the specimen 
hud a trunk 1 jn. 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 
.4. undulatifolia Becc.- from which it differs in the shape of the male flowers, 
these being oblong with a round top in .1. wndulatifoUa, ovoid and suddenly 
apiculatc in A. Amhong; 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 tlie leaflets at their base l»ave two auricles one on eucli margin instead of 
one, otherwise the leaflets are extremely alike in the two species. 
The leaves of young plants of A. Amhong in their terminal part have a 
striking resemblance to those of Wallichia ohlongifolia Griff., to which 1 had'* 
doubtfully referred a sterile and very incomplete specimen collected also at 
Zamboanga by R. Oarcia, No. 053 Ahern. In A. Amhong the scars of the fallen 
male flowers are orbicular, about nmi. in diameter and show the punotiform 
nuuks 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.
