Leaves sessile narrow lanceolate, 40 to 48 cm x 4 to 5 cm denticulate or subentire, 

 glabrous shining chartaceous, the midrib of the leaves hollow, leaves of young plants 

 lobed, the lobes extending sometimes to the midrib; peduncle (with flower) 2 to 3 cm 

 slender, naked below, many-flowered at the apex, 10 to 20 flowers in a crowded cluster on 

 pedicels of about 8 mm, bracts linear, twice as long as the bractlets; calyx glabrous, the 

 tube cylindrical, lobes linear or filiform, sometimes 4 cm long; corolla dark purplish red, 

 glabrous, semierect and slender about 4 cm long and 4 mm broad, antliers glabrous; berry 

 ovoid, yellow, crowned by the filiform calycine 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 drier and more open districts. It is as- 

 sociated with Antidesma platyphyllum var. /3., Xylosma Hawaiiense, Maba 

 sandwicensis var., Pisonia sandwicensis, Cyanea spathulata, and Cyanea kirtella. 

 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 

 the Hawaiian Islands only the genus Scaevola is represented of this family, with 

 a few species. 



SCAEVOLA L. 



Flowers hermaphrodite, zygomorphous, pentamerous. Calyx tube adnate to the ovary, 

 the limb very short, annular, truncate or 5-parted. Tube of corolla dorsally slit to thq 

 base, all lobes nearly of equal length or the two superior ones shorter. Filaments linear, 

 anthers free. Ovary inferior, rarely very shortly superior, bi-locular, ovules solitary in 

 each locule. erect, anatropous. Style entire, the margin of the indusium ciliate, very 

 rarely glabrous; stigma truncate or subbilobate. Fruit indehiscent, exocarp fleshy suc- 

 culent, or suberose, endocarp hard, ligneous, or bony, rarely crustaceous. Seeds solitary. 

 Embryo as long as the albumen, with terete or foliaceous cotyledons. Herbs, shrubs or 

 small trees with alternate, rarely opposite leaves, which are toothed, serrate, or entire. 

 Flowers rarely solitary, usually in cymes, bracteate and bracteolate, sessile or pedicellate. 

 Corolla white, purple or yellow. 



The genus consists of 83 species, distributed over Australia, but mainly West
