Araliaceae. 



This species, which like the two following has no native name, is a small tree 

 originally found by John Lydgate in the valley of Wailupe on Oahu, and re- 

 sembles somewhat Pterotropia gymnocarpa from the same mountain range. 



It has not been collected by the writer, and as there are no specimens of this 

 plant in herbaria in the Territory of Hawaii, the above short description will 

 have to suffice.

 Leaves about 3 cm long; leaflets 7 to 13, ovate or broad oblong, 5.5 to 8.5 cm long, 

 2.5 to 5 cm wide, on petiolules of 3 to 6 mm, obtuse, coriaceous glabrous; inflorescence 

 compound umbellate, 3 to 5 peduncles, 5 to 7.5 cm long, either free or united on a rhort 

 rhaehis of about 12 mm, each bearing an umbel of 16 to 20 pedicels of 12 mm in length; 

 calyx cylindrical 4 to 6 mm; petals 5 to 6, about 6 mm long; stamens 10 to 15, half as 

 long as the petals, with recurved anthers; ovary 5 to 6 celled; drupe ovoid or short cylin- 

 drical, 6 to 8 mm, inferior 5 to 6 ribbed or angled, truncate, the stigmas on a short stylopod. 



This species and a variety ,j. occur on the Island of Oahu on the slopes of 

 Waiolani and Konahuanui back of Honolulu. It differs from the foregoing 

 species mainly in the drupe, which is cylindrical and truncate, while the former 

 has ovoid drupes with conical vertices. 



It is a small tree about 20 feet in height and is peculiar to Oahu. The writer 

 observed several trees at the head of Pauoa Valley and on the slopes of Kona- 

 huanui. It is sparingly branching about 6 feet above the ground; the trunk is 

 vested in a gray, smooth bark, and is about 6 to 8 inches in diameter. Accord- 

 ing to Horace Mann, its native name is Ohe mauka or the mountain Ohe, while 

 Reynoldsia sandwicensis is Ohe makai; the latter, however, is also known as Ohe 

 kukuluaeo. 



Tetraplasandra Kaalae (Hbd.) Harms. 



TETRAPLASANDRA KAAIAE (Hbd.) Harms in Engl, et Prantl Pflzfam. Ill, 8 (1898) 

 30.— Triplasandra Kaalae Hbd. PI. Haw. Isl. (1888) 154;— Del Cast. 111. PI. Ins. 

 Mar. Pacif. VI (1890) 184. 



Leaves about 3 dm long, with widely clasping base, leaflets 7 to 11, ovate or ovate- 

 oblong, 7.5 to 10 cm long, 5 to 7.5 cm wide, on petiolules of 12 to 24 mm, obtusely 

 acuminate, rounded and unsymmetrical at the base, thick coriaceous, glabrous under- 

 neath, dark green; inflorescence thrice umbellate, 3 to 5 peduncles rising from a short 

 common rhaehis, each 4 to 6.5 cm long, with an umbel of about 12 rays of 2.5 to 3.5 

 cm or more long, these again umbellate with 10 to 12 pedicels of 8 to 12 mm; calyx 

 obconieal, glabrous, 2 mm; petals 6 at last expanded, 6 to 8 mm; stamens^ three times as 

 many as petals or less, 18 to 12; ovary 4- rarely 3-celled; stigmas sessile on a conical apex. 



This tree was first collected by Hillebrand on the summit of Mt. Kaala of the 

 Waianae range on Oahu at an elevation of 4000 feet. It is, like the two fore- 

 going species, a small tree 12 to 16 feet in height and of no economic value.
