Palmae. 41 
In the Punahou grounds several trees may be observed as well as in 
the grounds of some of the old residences in Honolulu. Its culti- 
vation for ornamental purposes has not been encouraged as it is not 
a very beautiful plant and dies after having flowered for some years. 
Arenga cbtusifolia Mart. 
Plate XVIII. 
This species is closely allied to the Sugar Palm, but differs from 
it in its more slender trunk and its stoloniferous habit — that is, it 
sends out underground rhyzomes which send up young shoots at 
internodes as much as ten feet or more from the parent tree. Thus 
one mature tree may produce quite a number of specimens by vegeta- 
tive reproduction. 
It is much handsomer than the Sugar Palm and much more 
graceful. The trunk is ringed and gray ; the leaves always dark 
green above and dirty white underneath. The flowering spikes are 
pendulous, and in the species in question the male spikes appear near 
the base of the trunk while the female ones are produced in the 
uppermost portion. Like the Sugar Palm it is a native of the Indian 
Archipelago, dense shady forests being its favorite locality. 
In Honolulu it is found only in two places, the handsomest 
specimens are in the grounds of Dr. Hillebrand who undoubtedly 
introduced it, and others are at Waikiki in the late Governor 
Cleghorn's premises. All species of the Arenga flower only once 
during the term of their existence. 
Hyophorbe amaricaulis Mart. 
Bottle Palm. 
The Bottle Palm reaches a height of sixty feet in its native land, 
with a bottle shaped trunk fifteen to twenty-four inches in diameter 
near the base, diminishing slightly upwards and becoming abruptly 
constricted near the base of the leafsheaths. 
The leafsheaths are somewhat trigonal and grooved on the face. 
The leaf consists of forty to sixty pairs of segments about eighteen 
inches long and two broad. The spadix branches in clusters, with 
a main stalk of about a foot. The fruit is elliptical, oblong; the 
seed elliptical and about half an inch long. 
This rather ungainly palm is a native of the Island of Mauritius 
and not known to occur wild elsewhere. It is cultivated in Hono- 
lulu and can be met with quite frequently in private grounds. The
