1918] ROCK—PELEA AND PLATYDESMA 265 
PELEA CINEREA (Gray) Hbd. var. suLFUREA Rock.—This is- 
HILLEBRAND’S 6, of which there is only one sheet in the Berlin 
Herbarium collected on Lanai. No specimen is represented from 
Maui. The writer collected this variety on the Island of Maui 
above Makawao slopes of Mount Haleakala. The leaves are pale 
and more or less glabrous on both sides. The capsule is smaller 
and sulphur-yellow. H1LEBRAND’s Lanai specimen has darker 
leaves, with a dirty olivaceous tomentum. A portion of his speci- 
men is in the College of Hawaii Herbarium, also Rock no. 8550, 
from Maui. 
PELEA CINEREA (Gray) Hbd. var. HAWAIIENSIS (Wawra) Rock.— 
P. hawatiensis Wawra, Flora 110. 1973; P. cinerea (Gray) Hbd. 
var. y Hbd. Flora Haw. Isl. 69. 1888.—Of HILLEBRAND’s specimens 
(three sheets in Mus. Bot. Berlin) two were collected by him in 1862 
at Kawaihaeiuka on Hawaii, the third is from the Kohala chain, 
Hawaii. A specimen from Kawaihaeiuka ex. herb. Hillebrand is 
in the College of Hawaii Herbarium, with specimens collected by 
the writer in South Kona, Hawaii, on Puuwaawaa Hill, June 15, 
1909, Rock no. 3654. 
The writer’s no. 10210 belongs here, although the leaves are 
glabrate or only slightly pubescent, but are of thick leathery texture 
as in var. sulfurea. They were collected in the Kipuka Puaulu near 
Kilauea on the slopes of Mauna Loa, alt. 4000 ft. July 1911. 
PELEA WaAwRAEANA Rock, Indig. Trees Haw. Isl. 231. 1913.— 
This species, while distinct, is closely related to P. sandwicensis 
Gray. In the Gray Herbarium there is a specimen ex. herb. 
Hillebrand labeled P. sandwicensis Gray microcarpa, which is iden- 
tical with P. Wawraeana. It was evidently included by Hitie- 
BRAND in P. sandwicensis, as he makes no mention of it in his Flora; 
the locality is given as the western end of Oahu. It is the writer’s 
no. 3020 in the College of Hawaii Herbarium. 
In the HILLEBRAND collection his var. 8 of P. sandwicensis is 
marked as var. macrocarpa Hbd., and his var: y of the same species 
var. tenutfolia Hbd. 
In the typical P.. sandwicensis the capsule has the carpels parted 
half way and in some specimens even more, while P. Wawraeana 
has distinctly cuboid capsules, which are much smaller than in 
- Sandwicensis.
