under the morning sun. Ipomoea tuberculata, the koali, is an- 

 other vigorous twiner, common in low and dry rocky places. 

 The flowers are delicate purple red, two inches long. Another 

 koali, Ipomoea insularis, is very common in the lower wood- 

 lands, where it envelopes the shrubbery and smaller trees 

 with its dense entangling masses of foliage. The fragile 

 azure-blue flowers are two to three inches long. 



The mauna-loa (Dioclca zdolacca) is a tall, woody 

 leguminous liana. It climbs up the coco-palms along the 

 beaches, and festoons shady groves in the lowland gulches. 

 The leaves are three-foliate; the flowers are clustered at the 

 ends of stiff peduncles, twelve to' fifteen inches long. The 

 bold flowers are deep blue or violet. Canarualia galeata, the 

 awiki-wiki of the natives, is a noteworthy leguminous liana, 

 and often climbs to great height. The pink or purple flowers 

 are borne in clusters at the ends of axillary peduncles four to 

 eight inches long, and are of distinct beauty. This vine occurs 

 both on the lowlands and in the lower forest zone, up to two 

 thousand feet elevation. 



An introduced leguminous vine, Mucuna urens, the "cow- 

 itch" of South America, is found on the uplands of Maui and 

 Hawaii. The young shoots and the pods of this tall climber 

 are clad with silky, stinging hairs. The leaf is three-foliate, 

 and very waxy underneath. The long axillary peduncles bear 

 fascicles of ten to fifteen flowers ; the flowers are large, two 

 inches long, and a lively bright yellow, with some red. 



A strong vigorous liana, the leguminous Vicia Mendesii, 

 is a characteristic high mountain form, as it is limited in range 

 to the upper margins of the extensive forests on Mauna Kea 

 and Mauna Loa, Hawaii, at an elevation of seven thousand to 

 eight thousand feet. The vines are very leafy, the leaves are 

 six to seven inches long, with eight to twelve leaflets, and 

 terminating in a compound tendril. The axillary inflorescences 

 each comprise six to eight large pale purple flowers, one to two
