On October 24, Mr. L. von Tempsky, Mr. Sam Baldwin and 

 I descended into the crater and camped in Kaupo Gap for five 

 days. The crater was crossed from Kaupo to Koolau, and as 

 much material as the short time permitted was collected. After 

 the return from Koolau Gap the flora of the Makawao forest 

 and of Puukakae was investigated and found to yield very in- 

 teresting species, among them a species of Nbni (Morinda tri- 

 mera), only previously collected by Mr. Lydgate fifty years ago. 

 One tree only was observed ; rediscovered . by Mr. L. von 

 Tempsky. 



ULUPALAKUA. 



Going on to Ulupalakua, Dr. Raymond's ranch, a study was 

 made of the different Eucalypts originally planted by Captain 

 Makee. Auahi and Kahikinui, seven miles from Ulupalakua, 

 where I stopped for twelve days, was the most interesting field 

 ever visited by me on any island, with the exception of Puuw'aa- 

 waa, Hawaii. On an area of 350 acres not less than 47 species 

 of trees were observed. Special mention may be made of one 

 tree, thought to be extinct since the time of Hillebrand. This 

 tree, belonging to the order of Sapindaceae, possesses an edible 

 fruit, of the size of a large potato, and is worthy of culti- 

 vation. About forty trees were observed and mature seeds of 

 the same collected; it is called Mahoe by the natives, and was 

 described by L. Radlkofer in the Sitz. math.-phys. bayer. Akad. 

 Wiss. XX. 1890; the name, Alectryon macroccocum. (See plate 

 19). 



Auahi and Kahikinui on Maui may be compared, and that 

 justly, to Puuwaawaa on Hawaii. Nowhere in the group, with 

 the possible exception of certain small areas in Kau, Hawaii, not 

 yet visited by me, is there such a variety of species to be found as 

 in these two localities. Both places have much in common, though 

 each has its peculiar species. Gossypiuns drynarioides, the red 

 native cotton, is also present at Auahi, previously thought to be 

 growing only on West Molokai. The genera Pittosporum, Pe- 

 lea, and others have most interesting representatives at Auahi, 

 Maui, as well as at Puuwaawaa, Hawaii. 



I returned from this trip to Maui early in December, since 

 when I have been occupied with the classification of the plants 

 collected in the above described trips. 



The number of specimens in the herbarium amounts to ap- 

 proximately 20,000 sheets, including duplicates. Over 1000 

 were received through exchange with foreign countries, repre- 

 senting genera of plants closely allied to Hawaiian genera.
