Polynesian Species of Myopomm — Webster 
71 
Shrubs to small trees, 2-8 m. high. Leaves 
mostly oblong-lanceolate, entire, glabrous, 
4- 15 cm. long, 0.5-3 cm. broad. Flowers 3-8 
per axil; pedicels 0.6-1. 2 cm. long. Flower 
parts varying from 5-9 but mostly 6-8, the 
sepals equal to or less than the number of 
corolla lobes. Sepals 1-3 mm. long. Corolla 
5- 8.5 mm. long, usually densely pubescent 
within, gladular spots absent or very few. 
Stamens usually 5-9 (very rarely less than 5), 
the same number as or less than the number 
of corolla lobes. Ovary 2-3 mm. long; style 
hirsutulous, 1.7-3. 5 (mostly 2-3) mm. long. 
Drupe creamy-white; endocarp usually 
strongly ridged, more or less laterally com- 
pressed, 3-8 mm. long, 3.5-8 mm. broad, 5- 
13-celled but typically 7-12-celled. 
TYPE: Hawaii, Kaupulehu, 2-3 miles east 
of Huehue, alt. 2,000 ft., Webster & Wilbur 
183^, in the Bishop Museum Herbarium (iso- 
type in the University of Texas Herbarium). 
This polymorphic subspecies is restricted 
to the lower dry forests on the island of Ha- 
waii. In its possession of a hirsutulous style 
it is unique among the groups within M. 
sandwicense, and it is further well marked by 
its large number of perianth parts, reduction 
of glandular spots on the corolla, and many- 
celled, sharply ribbed, endocarp. Morpho- 
logically, the typical form (Form 1) is fully as 
distinct from the other varieties of M. sand- 
wicense as many species of this genus are from 
one another. But the typical form intergrades 
with Form 2, which may be almost indis- 
tinguishable from some forms of var. sand- 
wicense. This is especially true of specimens 
from the vicinity of Punaluu in the Kau Dis- 
trict, but because they occur in the same area 
as plants of Form 1 and apparently are inter- 
mixed with them, it seems preferable to re- 
gard them as merely aberrant individuals of 
ssp. St.-Johnii, which for some reason (possi- 
bly they are remnants of an ancient popula- 
tion of var. sandwicense ?) are especially 
common in this vicinity. 
This group is named for Dr. Harold St. 
John of the University of Hawaii, who sug- 
gested the study of Myoporum and whose 
assistance has greatly helped to overcome the 
disadvantages of completing this work at a 
distance from the Hawaiian Islands.
