CASSIA L. Sp. PL 374. 1753. 

 Cassia chamaecrista L. Sp. PI. 379. 1753. 



Determined as above by Mr. C. L. Pollard. It is plentiful 

 about Honolulu, and is especially so on the dry slopes of 

 Punchbowl and Makiki. It must have been introduced since 

 1870, as Hillebrand makes no mention of its occurrence on any 

 of the islands. 



March 21 (1969), 



Cassia gaudichaudii H. & A. Bot. Beechy, 81. 1832. 



This, the only native species on the Islands, was first col- 

 lected by me on the dry slopes of Diamond Head, and at the 

 Pali, island of Oahu. On Kauai it was collected along the 

 Hanapepe river, and on the main ridge west of the Hanapepe . 

 It was not found above 1500 feet elevation, and was nowhere 

 plentiful. 



March to July (2022). 



Cassia occidentalis L. Sp. PL 377. 1753. 



Occasionally met with about Honolulu, but apparently not- 

 common. Observed also on Kauai, in Hanapepe valley. 



April to August (2174); original locality, "in Jamaica." 



Cassia laevigata Willd. Enum. Hort. Berol. 441. 1813. 



Hillebrand mentions this species as an occasional escape 

 from gardens. Since his departure from Honolulu in 1870, it 

 has spread and become well established at different points. It 

 is common about Honolulu along roadsides, where it climbs 

 over fences and trees. Near the eastern end of Oahu it is plen- 

 tiful along the road, at some distance from houses. On Kauai 

 it was found at an elevation of 3000 feet, growing in a deep 

 forest. The seeds may have been carried there by wild cattle, 

 but they rarely range low enongh to get into cultivated ground, 

 or even into the pastures of the domesticated cattle.

PAPILIONACEAE. 

 C AN A V ALIA Adans. Fam. PL 2: 325. 1763. 

 Canavalia galeata Gaud. Bot. Voy. Uranie, 486. 1830. 



Collected on grassy slopes above Waimea, Kauai, at an ele- 

 vation of 2500 feet. It is said to grow in forests of all the is- 

 lands of the group, "twining on trees, often to a great height." 

 At this station it trailed over the ground.
