Director's Report for iQip. 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. 



Botany 



An unusual amount of field work was accomplished by Mr. 

 Forbes during 19 19. 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 mteresting 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 moimtain 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
