PACIFIC SCIENCE, Vol. VII, July, 1953 
names are shown in quotation marks and are 
spelled exactly as they sounded to the writer. 
Economic uses for some of the species are 
also mentioned. 
It is interesting to note that each island in 
the Eastern Carolines has its own language. 
As a matter of fact, on Ponape there are dis- 
tinct language differences between different 
districts (e.g., Kid and Net) of the island. 
Following the catalogue of species for Mokil, 
Pingelap, and Ant, native names mentioned 
in this paper are tabulated for comparison 
with those of the high islands in the Eastern 
Carolines — Ponape, Kusaie, and Truk. In- 
spection of the table reveals striking differ- 
ences as well as similarities in the languages 
of these islands. 
MOKIL 
Mokil Atoll is located approximately 6°40 'N 
and 159°47'E. It is about 2 miles long and 1 
mile wide and is about 88 miles southeast of 
Ponape, 60 miles northwest of Pingelap, and 
180 miles northwest of Kusaie. Mokil com- 
prises three individual islets— Manton, Kalap, 
and Urak. The writer visited only Manton and 
Kalap. 
Mokil, formerly known as Duperrey Island 
and Wellington Island, was discovered by 
Duperrey on the corvette 'Ta Coquille” in 
1824 (U. S., 1944). In 1838, Lesson wrote 
an account of this voyage. Andersson (1854), 
botanist with the frigate "Eugenie,” and Skog- 
man (1856), also with the same ship, visited 
the island in 1852 and subsequently wrote 
summaries of the voyage in which the vege- 
tation and economic plants are mentioned. 
In 1854, Hammet included some notes on the 
vegetation in his narrative of the voyage of 
the "Serpent.” Moss (1889) gave a brief ac- 
count of the vegetation of the island, which 
he visited while touring Micronesia in 1886; 
and Christian (1899^, b) mentioned Mokil 
plants briefly in his accounts of the Caroline 
Islands. Thilenius (1927) and Filers (1934) 
included some information on the vegetation 
and listed a number of plants from a general 
survey of the Caroline Islands made by the 
Germans between 1908 and 1910. 
It appears that the only known previous 
collection of plants from Mokil was made by 
Ohba in the 1930’s. Several specimens of this 
collection were cited by Kanehira (1935). 
Murphy, who included Mokil in his geo- 
graphical account of the Eastern Carolines 
(1949), sent St. John a list of some 25 native 
names of plants recorded from the island. 
From these names, St. John compiled a ten- 
tative list of species (unpublished), most of 
which have been corroborated by the present 
writer. Both Weckler (1949) and Murphy 
(1950) have reported on the agriculture of 
Mokil. 
A total of 73 species of vascular plants, 5 
species of algae, and 2 species of bryophytes 
were either collected or observed by the writer. 
Numbers 2393 to 2601 inclusive were col- 
lected on Manton islet, numbers 2602 to 2633 
were taken from Kalap islet. Of the vascular 
plants, 34 are indigenous, 12 are crop plants, 
16 are ornamentals, and 11 are adventive 
weeds. Vernacular names were obtained from 
a native guide named Loren.
