HETEROSPATHE Scheffer 
HETEROSPATHE ELATA Scheffer in Ann. Jard. Buitenz. 1 (1876) 162. 
G. E. S. 129, 345, locally known as palma braba. 
The material is fragmentary, and Doctor Beccari, who has examined 
all the Guam material, has referred it to the genus only. It seems to 
me to represent the same species as the common form, which is frequently 
found in cultivation in the Philippines, Heterospathe data Scheff. The 
species undoubtedly has been introduced into Guam from the Philippines. 
Moluccas and the Philippines. 
N ! PA ( Nypa ) Wurmb. 
NIPA FRUCTICANS Wurmb in Verh. Batav. Genoot. 1 (1779) 350; Saf- 
ford 335. 
G. E. S. 180, locally known as nipa. 
Introduced from the Philippines, fide Safford; widely distributed along 
tidal streams in the Indo-Malayan region. 
In addition to the palms enumerated above, the following species are 
cultivated, all recently introduced; Dictyosperma alba Wendl. & Drude 
(G. E. S. 92, 421), Latania loddigesii Mart . ? ( G . E. S. 272, 401), Sabal 
adansonii Guerns. (G. E. S. 107, 344), Phoenix sylvestris (Linn.) Roxb., 
and Phoenix dactylifera Linn. (Safford p. 350). 
The palm flora of Guam is represented only by purposely introduced 
species. The coconut and the betle nut palms are of prehistoric introduc- 
tion, but all the others have been introduced within historic times. 
ARACEAE 
ALOCASI A Necker 
ALOCASI A MACRORRHIZA (Linn.) Schott in Schott & Endl. Melet. 
(1832) 18; Safford 179. 
Arum macrorrhizum Linn. Sp. PI. (1753) 965. 
G. E. S. 100, locally known as papao apaca; Costenoble 1198, locally 
known as papao atulong. 
A species of wide distribution in the Indo-Malayan region, frequently 
confused with Alocasia indica Schott, which Safford also reports from 
Guam. I am at the present time of the opinion that Alocasia indica 
Schott is really not specifically distinct from the older Alocasia macrorrhiza 
Schott, although kept separate in Engler’s monograph and by other authors.

Cultivated in all tropical countries, where native uncertain.
