ago. Only one tree was observed. The writer then went 
on to Uhipalakna, Dr. Raymond's ranch, where he made a 
study of the different eucalypts originally planted by Captain 
Makee. Auahi and Kahikinui, seven miles from Ulupalakua, 
where the writer stopped for twelve days, was the most inter- 
esting field ever visited by him on any island with the ex- 
ception of Puuwaawaa, Hawaii. On an area of 350 acres not 
less than 47 species of trees were observed. Special mention 
may be made of one tree, declared extinct since the time of 
Hillebrand. This tree is allied to the Chinese Litchi, and is a 
delicious fruit, reaching the size of a large potato, and is 
worthy of cultivation. About 40 trees were observed, and 
mature seeds of the same collected; it is called Mahoe by the 
natives. 
Regarding the stock-poisoning plants on Maui, particularly 
East Maui, the writer would advocate the extermination of 
one particular plant called Huamakani by the natives, a 
Passion vine (Passiflora triloba), which seems to spread 
rapidly and is also poisonous. The same if eaten by calves 
produces paralysis of the whole nervous system, brings on 
convulsions and constipation, high temperature, and finally 
death. Besides, on Maui, the plant is found plentifully at 
Kualoa, Oahu, at Mr. Swanzy's ranch. 
PLANT EXCHANGE.
