Director's Report for 1919. 175 
Cooke III was made to Kauai. Through the courtesy of the owner head- 
quarters for nearly three weeks were made at the country house of Mr. H. P. 
Faye in the valley of Halemanu at an elevation of about 3500 feet. Over 
twelve thousand specimens, some of them among the rarest species collected 
in Hawaii, were the result of this trip.

An unusual amount of field work was accomplished by Mr. 
Forbes during 1919. Twelve trips on the island of Oahu resulted 
in adding about 125 sheets of specimens to the collections. From 
July to the end of the year, the field of operaiton was the island of 
Maui. To quote from Mr. Forbes: 
Through the kindness of Mr. S. A. Baldwin I was enabled to make 
headquarters at Ukulele, on the northern slopes of Haleakala at an elevation 
of about 5000 feet. From a camp several miles east of Ukulele I was enabled 
to visit a most interesting transition forest where there is an intermingling 
of species of plants characteristic of the upper rain forest and of the high 
upland zone. There was also a most interesting narrow zone with a bog 
flora. In ravines above this camp two species of Argyroxiphium were seen. 
Two camps were established within the crater of Haleakala. The first stop 
was in the Keanae Gap, a very wet locality but very interesting botanically 
on account of the close proximity of plant communities of recent lava, bogs, 
and rain forest. The second camp was near the large water hole opposite 
Oilipuu toward the Kaupo Gap. From this place trips were made out of the 
crater and down the north and northeast slopes. The rain forest is very 
dense in this section. The most interesting plant habitats are a series of 
cones and flats which extend down the mountain toward Hana. The first 
cone contains a lake surrounded with a zone of Carex; lower cones and flats 
have an open bog flora. In one of the bogs there occurs a very peculiar 
species of Wilkesia with a branching habit which may be a form of W. 
Grayana Hbd., but is probably another species of this rare genus. In the 
rain forests there is a beautiful species of Clermontia with reddish flowers 
which has not been described. On several trips down the Kaupo Gap, the 
most interesting plant observed is a fragrant flowered form of Viola Cha- 
missoniana Ging. I returned to Honolulu with 2208 sheets of specimens. 
For aid in many ways while on this trip I am indbeted to Messrs. S. A. 
Baldwin, W. A. Field, H. A. Baldwin and Rosencranz. 
After examining the collections and attending to accumulated routine, on 
my return to Maui in November, a base was established at Hana and a 
camp in Kipahulu Valley at an elevation of 1600 feet. In olden times this 
valley was probably in a high state of cultivation as taro patches are numer- 
ous, and acres of land are covered with wild banana; but now the under- 
growth is very dense, and old standing Koa trees indicate that the present 
growth is a secondary or even tertiary covering. Among the most interesting 
plants found here is a species of Cyrtandra distinguished from other de- 
scribed Hawaiian species by the peculiar shape of its calyx; and a species 
of Cyanea with orange colored blossoms. The Cyanea is identical with 
C. Copelandii Rock which was known only from a small area on the island 
of Hawaii. A short trip was taken toward Kaupo, going up the Pualaia
