pedicels of about 8 mm, bracts linear, twice as long as the bractlets; calyx glabrous, the 
tube cylindrical, lobes linear or filiform, sometimes 4 em long; corolla dark purplish red,

ovoid, yellow, crowned by the filiform calyeine lobes. 
The Hahalua, which reaches a height of sometimes 40 feet, or about 13 m, has 
a pronounced palm-like habit, possessing a single erect trunk which is densely 
covered in its upper portion with rhomboid leaf-scars, bearing at the end a crown 
of sessile leaves. 
The Hahalua is peculiar to the Island of Kauai, where it inhabits the middle 
forest zone on the leeward side in the (rier and more open districts. It is as- 
sociated with Antidesma platyphyllum var. B., Xylosma Hawaiiense, Maba 
sandwicensis var., Pisonia sandwicensis, Cyanea spathulata, and Cyanea hirtella. 
It flowers in the summer months. 
Numerous species of caterpillars feed on the fruits and withered flowers 
The leaves of the young plants are always lobed, a characteristic found quite 
often in young plants of Cyaneae, especially in those of Section III Palmae- 
formes. The milky juice of this species is yellow. 
GOODENIACEAE. 
The family Goodeniaceae consists of 13 genera, of which 10 are only found in 
Australia. The species number 291, of which 27 are not found in Australia. In

a few species.
