PACIFIC SCIENCE, Vol. V, January, 1951 
Form 3. Leaves pubescent; flower parts 6-7; 
cells of drupe 7-9* 
Puuwaawaa, Rock 3800 (BISH, NY). In 
several respects this form is intermediate be- 
tween var. Fauriei and ssp. St.-Johnii. 
5. Myoporum sandwicense ssp. sandwi- 
cense var. lanaiense Webster, var. nov. 
Pis. II, 21, 33; III, 43 
Drupa depressi-conica; endocarpium non 
costatum. 
Leaves lanceolate, acuminate, entire, gla- 
brous, 6-13.5 cm. long, 0.8-1. 8 cm, wide. 
Flowers 2-4 per axil; pedicels 0.7-1 cm. long. 
Calyx lobes 5, 2-3 mm. long, ovate-acumin- 
ate. Corolla 5-lobed, 5-8 mm. long, glabrous 
or pubescent, the tube 2.5-4 mm. long. Ovary 
about 2 mm. long; style 1.8-3 mm. long. 
Drupe probably whitish in color; endocarp 
depressed-conic or hemispheric in outline, 
not or scarcely ridged, 3-4.5 mm. high, 6-9 
mm. broad, 5-7-celled.^ 
TYPE: Mahana forehills, Lanai, July 1910, 
Rock 8119, in the Bishop Museum Herbarium. 
Isotypes are in the Gray Herbarium and 
Naturhistorisches Museum, Vienna. 
This variety, named for the island on which 
it occurs, is apparently now restricted to the 
dry forest near Kanepuu at the northwest end 
of the island. Ordinarily it is easily distin- 
guished from var. sandwicense by its strongly 
depressed endocarp. Rarely, plants of var. 
sandwicense^ such as Webster 1081 from Oahu 
and Forbes 477. M from Maui, may have de- 
pressed endocarps which appear superficially 
similar, but these are easily distinguished in 
cross section by their thinner walls (compare 
Figs. 39 and 43). 
The status of var. sandwicense on Lanai is 
rather uncertain. Judging from the few collec- 
tions at hand, it seems to occupy a lower alti- 
tudinal 2 one than var. lanaiense, but further 
collecting will be necessary before its distri- 
butional relationship to var. lanaiense will be- 
come clear.

6. Myoporum sandwicense ssp. sandwi- 
cense var. stellatum Webster, var. nov. 
Pis. I, 1; II, 20, 32; III, 42 
Prinastrum cauliflorum Nutt, ex Gray, Am. 
Acad. Sci. 6: 52. 1866 (herbarium name pub- 
lished in synonymy). 
Folia hirtella, ramuli hirtelli; pili ramosi. 
Branchlets and leaves pubescent with 
branched hairs, somewhat glabrescent with 
age; leaves elliptic-lanceolate, usually entire, 
4- 9 cm. long, 0.7-2. 2 cm. broad. Calyx mostly 
5- lobed, pubescent, sepals 1.2-2. 5 mm. long. 
Corolla 5-lobed (rarely 6-lobed), 5-7 mm. 
long, glabrous or pubescent within, the 
glandular dots rather inconspicuous. Stamens 
mostly 4 or 5, if 5 then often one reduced. 
Ovary 2-2.5 mm. long; style 2-2.8 mm. long. 
Drupe creamy- white; endocarp subglobose, 
ridged, 3-5 mm. in diameter, 5-7-celled. 
TYPE: Oahu, Ewa coral plain near Barbers 
Point, alt. 10 ft., Webster 1243, in the Bishop 
Museum Herbarium (isotype in the Univer- 
sity of Texas Herbarium). 
This distinctive variety is now restricted to 
the low plain of emergent coral at the south- 
western corner of Oahu. It is known from 
Kauai on the basis of a single collection by 
Nuttall, but has not been collected on that 
island in the century since then. If Nuttall’s 
rather questionable locality was correct, the 
variety has evidently become extinct on
