Polynesian Species of Myoporum — Webster

Kauai. On Oahu it originally grew from the 
mouth of Pearl Harbor to Barbers Point, but 
it has been exterminated over much of this 
range by the encroachment of military es- 
tablishments. In the vicinity of the lighthouse 
it is still quite abundant, however, and will 
continue to persist unless the vegetation is 
entirely removed. Ecologically, it must be 
highly specialized, as it has become adapted 
to a calcareous substrate quite different from 
the lateritic or basaltic soils on which the 
other varieties grow. 
Although this variety superficially resem- 
bles var. Degeneri in the pubescent leaves, it 
has been independently derived, probably 
from Oahu Form 5 of var. sandwkense. This 
relationship is especially evident in the fact 
that var. stellatum shows the tendency toward 
the loss of the fifth stamen which is fully ex- 
pressed in the form from the Waianae Range. 
The name of this variety alludes to the ap- 
pearance of the branched hairs, a character 
unique in the genus as far as I can determine.

7. Myoporum sandwicense ssp. sandwi- 
cense var. Degeneri Webster, var. nov. 
PI. I, 10-11 
Folia elliptica hirtella serrata; pili simplici; 
ramuli glabri. 
Branchlets glabrous. Leaves mostly ellip- 
tic, less commonly lanceolate, pubescent, the 
hairs unbranched, entire or serrate, 4-9 cm. 
long, 1-2.5 cm. broad. Flowers 5-6 per axil. 
Calyx lobes 5, glabrous or pubescent, 1.5- 
3.5 mm. long. Corolla glabrous or pubescent 
within, 5-7.5 mm. long. Stamens 5, rarely 4 
or 6. Ovary 2-3.5 mm. long; style 2-5 mm. 
long. Drupe color unknown, presumably 
white; endocarp 5-9 mm. long, 5-7-celled. 
TYPE: East Maui, north mauka of Ulupala- 
kua, Degener 12183, in the Bishop Museum 
Herbarium. 
This variety occurs on the dry leeward 
slopes of Haleakala, East Maui, from near 
Ulupalakua to the Kaupo Gap; a form from 
Molokai is referred here for convenience. It 
is named for Mr. Otto Degener, long a stu- 
dent of the Hawaiian naio, who illustrated it 
in his book. Plants of Hawaii National Park.

EAST MAUI: 
North mauka of Ulupalakua, Degener 12183

pakahawai gulches, Forbes 1940. M (BISH);

along east side of Kaupo Gap, Degener 
11600 (NY). 
Although the plant from Molokai is placed 
in var. Degeneri for convenience, it probably 
has arisen independently of the Maui plants 
and may represent a different variety. How- 
ever, until the confusing forms from Molokai 
are better understood, it seems unwise to de- 
scribe any new varieties from there.
