Polynesian Species of Myoporum — ^Webster 
61 
endocarp 2-10 mm. long, 2-9 mm. broad, 
subglobose to depressed. 
This extremely variable and complex sub- 
species is restricted to the Hawaiian Islands. 
3. Myoporum sandwicense ssp. sand- 
wicense var. sandwicense. 
Pis. I, 2-6; II, 16-17, 27-30; III, 38-40 
Myoporum sandwicense A. Gray, Proc. Am. 
Acad. Sci. 6: 52-53. 1866 (in part, excluding 
reference to Douglas and Nuttall collections). 
Leaves mostly lanceolate to oblong or 
ovate lanceolate, rarely sublinear or ovate, 
4- 22 cm. long, 0.5-3. 8 cm. broad, glabrous 
(except in one form). Flowers in clusters of 
2-9 (mostly 3-6); pedicels 0.3-1. 5 cm. long. 
Calyx mostly 5-lobed (rarely the lobes 4, 6, 
or 7); lobes broadly to narrowly ovate or 
oblong, 1-3 (rarely 4) mm. long. Corolla 
5- lobed (rarely the lobes 6-7), glandular- 
punctate, glabrous or pubescent within, 4.5-8 
(rarely to 9-5) mm. long. Stamens usually 5, 
occasionally one reduced (more rarely the 
number 4 or 6-8). Ovary 4-10-celled but 
mostly 5-7-celled; style 1.5-3 (rarely 4) 
mm. long. Drupe creamy-white, never pink 
or purplish; endocarp 2-6 (rarely 7) mm. 
long, mostly subglobose or top-shaped, 
usually ribbed. 
LECTOTYPE: Isles Sandwich, Oahu, Remy 
462 in the Gray Herbarium. 
This extremely polymorphic variety is 
found at present on all the main islands 
except Hawaii and Kahoolawe. It is the 
heterogeneous residuum which remains after 
the more well-marked populations have been 
removed, and some of the forms enumerated 
here may warrant reappraisal when better 
known. 
It has seemed best to arrange the various 
forms in a geographic sequence, first for the 
sake of convenience and also because forms 
from different islands which appear morpho- 
logically similar are most likely related not 
to each other but to adjacent forms on the 
same island. To give an idea of the corres- 
pondence and relationships of the forms, 
however, the following key is submitted with 
the caution that a clear differentiation of the 
forms is not possible.
