ture of the vegetation on the high plateau of Kauai, bordering the extensive open 

 bogs of Kauluwehi, Alakai, and Lehua makanoe. At the summit of Waialeale it 

 is a small tree or rather shrub, with almost sinuate leaves. At lower elevations 

 the leaves are entire. It is associated with Pelea, Dubautia (the high mountain 

 forms), Labordea, Lobelia Gaudicliaudii, Scaevola glabra, etc. On Oahu it is 

 confined to the summit ridges of the Koolau range, especially Konahuanui, and 

 has also been found on Kaala of the Waianae range. 



The wood of the Lapalapa is whitish, with a yellow tinge, and is said to burn 

 when green. 



EPACRIDACEAE. 



The family Epacridaceae has only a limited distribution. The bulk of its 

 species is to be found in Australia and Tasmania, with quite a number of genera 

 in New Zealand. The family possesses 21 genera of which 273 species occur in 

 Australia. Of all the 21 genera only one genus with one subgenus is not to be 

 found in Australia or Tasmania. A few endemic species occur in New Cale- 

 donia and the most southern part of South America, besides a few species of 

 large genera in India and the Malayan-Archipelago. Here in the Hawaiian 

 Islands we have two species represented, of the subgenus Cyathodes, formerly 

 recognized as a genus, but now a subgenus of Styphelia by Drude. 



STYPHELIA Sol. 



Corolla campanulate, funnel-shaped or tubular. Stamens enclosed in the tubes of 

 the corolla; anthers hardly visible, or exserted on long filaments. Style longer than the 

 stamens, stigma simple small. Disc a ring or composed of 5 lobes or scales. Ovary usually 

 5-celled, rarely through abortion 3- or 2-celled. Fruit a berry or drupe. Shrubs or low trees 

 with usually broad or narrow lanceolate, spathulate-elliptical leaves, the flowers single, 

 axillary, or in racemes, with 2 to several bracts. 



This is the richest genus in the family Epacridaceae of which the largest 

 number of species belongs to Australia. The Hawaiian species St. Tameiameia 

 and St. Grayana come under the fourth subgenus Cyathodes which may be de- 

 scribed as follows: 



Subgen. Cyathodes Lab. 



Calyx surrounded by many bracts; corolla funnel-shaped, its tube hardly protruding 

 from the calyx, inside and at the throat without glands and beardless; stamens enclosed; 

 ovary 5-10 celled. 



The subgenus Cyathodes occurs in Tasmania, New Zealand, and in the Ha- 

 waiian Islands with two species.
