Araliaceae. 



REYNOLDSIA A. Gray. 



Calyx border short, undulate. Petals S to 10, linear-laneeolate, valvate in the bud. 

 Stamens as many as petals and somewhat shorter. Ovary 8 to 10 or 15 to 22 celled. 

 Stigmas arranged in a circle around the very short, thick style. Drupe globose, some- 

 what fleshy. Pyrenae laterally compressed, chartaceous or erustaceous. Embryo small 

 at the apex of an even fleshy albumen. — Unarmed, glabrous trees. Leaves large, impari- 

 pinnate, with 3 to 9 oval or cordate sinuate-crenate or (in the species not from Hawaii) 

 entire leaflets; exstipulate. Flowers racemose-umbellate on the alternate branches of a 

 terminal panicle. Bracts minute linear. 



A genus of three species, one inhabiting Tahiti (R. verrucosa Seem.), one 

 Samoa (Savaii) (B. pleiosperma A. Gray), and the third our islands.

Leaves about 3 dm long, glabrous, the slender petioles shortly toothed at the dilating 

 l<ase (according to Hillebr. but not in the writer's specimens); leaflets 7 to 11, ovate to 

 cordate, 7 to 10 cm x 5 to 8.5 cm on petiolules of 2 cm in the upper pair of leaflets and 

 4 cm in the lower pair, obtuse or bluntly acuminate, repando, or sinuate crenate, stiff 

 membraneous, light green, glossy; inflorescence of 3 terminal peduncles, rising from a 

 short common rhachis, each about 12 to 20 cm long and branching from the base upward, 

 "the branches horizontal, 4 to 5 em when with flower, 7 to 9 cm when in fruit, and 

 jaeemose umbellate in their upper halves, with pedicels of 10 to 12 mm; calyx obeonical 

 -truncate, 2 to 3 mm; petals 8 to 10, about 6 mm long, cohering; ovary 8 to 10 celled, 

 wholly inferior; drupe globose 6 to 8 mm in diameter ribbed when dry; pyrenae erustace- 

 ous, with smooth sides. 



The Ohe is a very peculiar Hawaiian tree, which sheds its leaves in the winter 

 months and flowers before the reappearance of the leaves in the early summer. 

 When bare, it resembles somewhat the Wiliwili, which also sheds its leaves dur- 

 ing the rainy season. 



It reaches a height of from 15 to 60 feet and develops thick and often short 

 trunks with bluish-gray, smooth bark, and a spreading crown with straight as- 

 cending branches. The leaves, which are about a foot long, consist of 7 to 11 

 leaflets, heart-shaped at the base. The flowers are arranged on stiff, erect term- 

 inal peduncles, rising from a short common rhachis, branching from the base 

 upward, and racemose-umbellate in the upper half. 



It is peculiar to the very dry districts of the lowland zone and especially on 

 •aa lava fields, where the heat is intense and rain is very infrequent. The trunk 

 •exudes a very thick resin or gum which is of a clear yellowish-golden color. 



On Maui it is not uncommon on the lava fields near Ulupalakua on the south- 

 •ern slopes of Haleakala, as well as on Molokai, where it can be found at the 

 western end at Mahana in gulches, and on the heights above Kamolo, associated 

 with Dracaena aurea (Halapepe). On Hawaii, on the lava fields of North and 

 "South Kona, it reaches its best development, trunks with a diameter of lyi to 2 

 feet being not uncommon. It also grows on Lanai on the slopes above Manele
