Pic Rouge, northwest side, alt. 140 m., St. 
John & Fosherg 15957 (BISH); Mt. Taraia, 
south side, alt. 250 m., St. John & Kondo 
15996 (BISH). 
11. Myoporum rapense F. Brown, Bishop 
Mus. Bui. 130: 278-279, %• 42. 1935. 
Shrubs or trees, 1-10 m. high. Leaves lan- 
ceolate or somewhat obovate, sharply serrate, 
glabrous, 4-11.5 cm. long, 0.7-2 cm. broad, 
acute to acuminate, alate-petiolate. Flowers 
1- 4 (rarely 5) per axil, often 1 or more abor- 
tive; pedicels 0.5-1. 5 cm. long. Calyx lobes 5, 
glandular- dotted, lanceolate and acuminate, 
2- 3.5 mm. long; margins entire, minutely 
serrulate, or prominently ciliate. Corolla 5- 
lobed (rarely 6-lobed), white, pink, or purple- 
spotted in the throat, with a heavy sweet or 
sometimes fetid odor, 8-12 mm. long, pube- 
scent within. Stamens 4, all well developed or 
one a rudiment. Ovary 2. 5-3. 5 mm. long; 
style hirsutulous, curved at the base, 4-6 mm. 
long. Drupe brick- or purplish-red; endocarp 
turbinate or oblong-ellipsoid, not or scarcely 
ridged, 5-8 mm. long, 3. 5-5. 5 mm. wide, 
3- 6- celled (often one or more cells empty). 
This species occurs on Tubuai, Raivavae, 
and Rapa and is more constant morpho- 
logically than is its probable derivative M. 
Stokesii. It is separated from this latter species 
by characters which are very stable for the 
genus Myoporum, and only one specimen is 
in any way intermediate. The form of M. 
rapense on Raivavae has typical leaves and 
fruit but flowers more nearly the size of M. 
Stokesii. This form does not seriously break 
down the boundaries between the two species, 
however, and it seems best to maintain them 
as distinct. 
While M. rapense is clearly separable from 
M. Stokesii, it is not nearly so easily dis- 
tinguished from the New Zealand M. laetum. 
For the present, however, its more incon- 
spicuously punctate leaves (fully discussed 
under Morphological Criteria earlier in this 
paper) may serve to separate it. 
12. Myoporum rapense var. rapense 
Pis. I, 15; II, 25, 37; III, 46 
Myoporum rapense F. Brown, Bishop Mus. 
Bui. 130: 278-279, fig. 42. 1935. 
Leaves lanceolate or obovate-lanceolate, 
4-10 cm. long, 0.7-2 cm. broad. Calyx lobes 
lanceolate, acuminate, 2-3 mm. long; mar- 
gins entire or minutely serrulate. Corolla 8-9 
(rarely 11-12) mm. long. Ovary 2.5-3 mm. 
long; style 4-5 (rarely 6) mm. long. Endo- 
carp 5-8 mm. long, 3. 5-5. 5 mm. broad, 
3-6-celled. 
TYPE: Rapa, alt. 170 m., Sept. 13, 1921, 
Stokes 161, 'm the Bishop Museum Herbarium. 
Brown (1935:279) cited two collections from 
Rapa as types. I have chosen the first one as 
the lectotype, since the number of the other 
{Stokes 90) is the same as the type of M. 
Stokesii.
