July 11-17 Enderbury Island - Summary
(Taken from notes by Peter Marshall).
The plant covering at Enderbury is much more interesting than
Howland and Baker because the size of the island allows several different
conditions to exist, with the same basic plants compensating to adjust
to there different surroundings. A good example of this is plant No. 13,
which grows in each of the three environments (a. guano sand soil near
camp, b. salt soaked guano of the lagoon, c. barren piles of rock and
reef). In the pressing of this sample, I show two of the forms, the
normal and the dry. (Left out is the bush growth of the interior.)
Plant No. 1 - Tournefolia. Two clumps of tress on the island, one
(north of camp) very large and supporting a large colony of greater
frigates and one near the south east which is much smaller. The growth
seems to now be checked by the birds, which leads one to believe that
they grew up to their large size when there were much fewer birds.
All the upper branches of these small trees (8 - 20 feet) are now dead
and the only growth occurs at the bottom.
Plant No. 2 - Sesuvium. Literally covers and blankets the inner part
of the island. Small white flowers.
Plant No. 3. - Leaves in line type succulent. Common along outer 200 feet
of island. Very adaptive to good and bad conditions.
