flowers and narrow lanceolate leaves. The dry districts were of 

 the greatest interest, especially the valley of Kaiholena. Here 

 also several new species were discovered. The material collected 

 on the Island of Lanai comprises about 2500 specimens; the 

 largest amount of species of Lichens were found on that Island. 

 After a month's sojourn on Lanai I left the Island for Lahaina 

 on the "Nunulaweleka," a whale-boat carrying- the U. S. mail 

 between Halepalaua and Lahaina, Maui. 



Through the courtesies of Mr. Weinzheimer, manager of the 

 Pioneer plantation, in supplying men and pack mules, I was en- 

 abled to ascend the highest peak on West Maui, Puu Kukui, 

 5788 feet elevation. Gamp was pitched at an elevation of 4200 

 feet on the edge of Honokawai gulch. From there the summit 

 could be reached in four hours' walk through the swampy jungle. 

 P"uu Kukui is of greatest interest, its vegetation being of similar 

 character as Waialeale of Kauai, elevation 5250 feet, which 

 mountain I ascended the previous year. With exception of the 

 insect-eating plant Drosera longifolia and a new species of Com- 

 posite, since described by me in The Torrey Botanical Glub Bul- 

 letin, the flora is practically the same. Though several plants 

 are peculiar to Puu Kukui as a violet, lobelia, and several others, 

 I was greatly surprised in finding the Silversword, or Ahinahina 

 of the natives, known from Haleakala and Mauna Kea, at the 

 summit of West Maui, growing in a veritable pool. As the plant 

 was not in flower it was impossible to determine if the same is a 

 new species or not, but it may be an intermediate form of the 

 green silversword from the western slopes of Haleakala and the 

 well-known silversword from the crater and Mauna Kea. About 

 1000 specimens were secured on this trip. 



EXPLORATION OF HALEAKALA. 



Having returned to Honolulu the latter part of August, on 

 September 23, 1910, a trip was made to East Maui in compliance 

 with instructions to explore the slopes as well as the crater of 

 Haleakala. 



The first camp was pitched near Olinda at Mr. Fred. Harvey's 

 survey camp. From there the forest of Hamakuapoko was ex- 

 plored as best as conditions permitted; from Waikamoi to Puo- 

 haokamoa and to the headwaters of Honomanu, where the jungle 

 is dense and the vegetation exceedingly tropical; large material 

 was secured at that locality. 



The camip was then transferred to Ukulele Dairy, 1000 feet 

 higher than Olinda. The upper slopes of Haleakala, whose vege- 

 tation consists mainly of shrubby, woody composites and geran- 

 iums, besides a large number of plants belonging to other en- 

 demic genera, were traversed in all directions.
