Araliaceae. 



10 to 12 rays, with or without a short common rhachis, each 10 to 15 em long and bear- 

 ing at its apex an umbel of 15 to 30 flowers on thick and long pedicels of 2.5 to 5 cm; calyx 

 8 to 12 mm long broad tubular, slightly constricted below the wavy denticulate border; 

 petals 7 to 8, triangular lanceolate, 12 mm long, pink or reddish, coriaceous, glabrous, at 

 last expanded, the open corolla measuring sometimes 3.5 cm in diameter, the largest in the 

 genus; stamens 6, 7 or 8 times as many as petals, 8 to 10 mrn long, in two rows; ovary 6 to 

 8 celled, the stigma on a short stylopod of 1 mm; drupe globose, about 3 cm or often more in 

 diameter, somewhat fleshy, strongly ribbed when dry; pyrenae compressed, thick coriace- 

 ous, deeply notched at the upper inner angle, and with two prominent ridges on each side. 



The Ohe kikoola is a medium-sized tree with an erect trunk of 30 to 40 feet 

 in height and a diameter of a foot or more. The erect bole is vested in a grayish- 

 white smooth bark. It divides very sparingly near the top into rather short as- 

 cending branches, which bear large leaf whorls at the apex. The leaves are 

 over a foot long and consist of 5 to 13 leaflets. The inflorescence is a terminal 

 umbel of several rays, bearing at its apex peculiar rose-colored flowers, which 

 are the largest in the genus, measuring an inch or more in diameter. The drupe 

 is globose, an inch or more across, somewhat fleshy, and becomes ribbed on drying. 



The tree is peculiar to the Island of Kauai, where it grows on the leeward 

 side above Waimea at an altitude of 3600 feet, in the drier forest or outskirts 

 of the woods around Kaholuamano. It is associated with Cyanea leptostegia, 

 Cryptocaria Mannii, Bohea Mannii, Sidero ylon sandwicense, Elaeocarpus hifidus, 

 etc. It also is not uncommon at Halemanu, wtiere it was first collected by Dr. 

 Wawra of the Austrian Exploring Expedition ship "Donau," and named by 

 him after the district of Waimea. 



The wood is whitish, of a silky, wavy green, and of medium strength. 



Tetraplasandra Waialealae Rock. 



TETRAPLASANDRA WAIALEALAE Eock Coll. Haw. Publ. Bull. 1. (1911) 10, pi. I. 



Leaves 30 to 45 cm long; leaflets oblong acuminate thick coriaceous, unevensided at the 

 base, otherwise rounded; inflorescence a terminal compound umbel of usually 4 peduncles, 

 each about from 7 to, 10 cm long, bearing 6 rays about 6 cm long, each bearing an umbel 

 of 2-5 pedicels about 2 cm long; calyx tubular purplish-black with an undulate border; 

 petals 5 to 7, triangular, thick, with a prominent median nerve, glabrous; stamens in two 

 circles, four times as many as petals; ovary 6 celled; stigma on a conical stylopod of 5 mm. 



This remarkable tree, which as far as is known has no native name, is of 

 rather small size, 15 to 25 feet high, with sub-erect long branches, bearing, 

 crowded at their ends, irregularly pinnate leaves. The leaflets are dark-green 

 and glossy; the trunk is rather short, is vested in a white bark, and is about 6 

 to 8 inches in diameter. 



The inflorescence is compound umbellate, not as large as that of the Ohe 

 kikoola, but is also terminal. 



This interesting tree, which the writer discovered on the summit of Mt. Wai- 

 aleale, on Kauai, 5200 feet elevation, was named by him after that wonderful, 

 mountain. Unlike the Ohe kikoola, which grows in the dryer forest on Kauai 

 back of Waimea, it inhabits the high summit swamp, where the rainfall is im- 

 mense. This swamp is enshrouded by clouds nearly all the year round, and is 

 swept by the strong trade winds for over nine months of the year.
