Rutaceae. 



sepals exactly as in the species; male flowers smaller, stamens of all sizes some as long 

 as the petals; ovary pubescent stigma with 4-globular lobes, and sessile; capsule little 

 smaller, endocarp glabrous. 



This variety, which seems to be a typical liane, forming dense tangles, was 

 collected flowering and fruiting by the writer in the valley of Mahana, Island of 

 Lanai, on the dry open wooded forehills, on July 24, 1910. The type is no. 8057 

 in the College of Hawaii Herbarium.

New branchlets, inflorescence, etc., tomentose with a rather hirsute pubescence; 

 leaves opposite, oval or oblong, thick coriaceous, glabrous above, more or less puberulent 

 beneath, when young pubescent on the thick midrib, very veiny and reticulated, punctate, 

 rounded at the apex or acute and mucronate, 7 to 15 cm long, 4 to 8 cm wide, on stout 

 lignescent petioles of 20 to 35 mm; cymes axillary, short peduncled, 3 to 9 flowered; 

 pedicels short, annulate by the broad scars of the ovate subulate bracts; sterile flowers: 

 sepals ovate, acute, puberulous, 3 mm; petals 7 mm, oblong acute; stamens 8, 4 as long or 

 longer than the petals, on broad filaments, 4 shorter of unequal length; anthers sagittate; 

 ovary smaller than in the fertile flowers, pubescent, style pubescent 1.5 mm long with 

 short bluntly notched stigma; fertile flowers smaller, ovary tomentose, style longer, with a 

 bluntly, short-lobed stigma; stamens not quite the height of the ovary, anthers smaller; 

 capsule finely tomentose, or glabrous when old, deeply four lobed, 20 to 24 mm in diameter, 

 the cocci oval, endocarp finely pubescent. 



A medium-sized tree, but perhaps one of the largest for the genus Pelea, reach- 

 ing a height of 30 feet or little more, with a trunk 10 to 12 inches in diameter. 



The Alani occurs in the wet forests of Oahu, especially of the main western 

 range, where it is a common tree at an elevation of 2000 to 2500 feet. The writer 

 met with it most plentifuly in the mountains of Punaluu, on the windward side 

 of Oahu, as well as on Konahuanui, back of Honolulu. Several varieties of IT. is 

 species are known, perhaps doubtful. According to Dr. Wm. T. Brigham, the 

 tough wood of this species was used for tapa beaters. (Flowering and fruiting 

 November 14, 1908; no. 912, Mts. of Punaluu; fruiting Konahuanui, November, 

 1912, no. 10215 College of Hawaii Herbarium.) 



Hillebrand's var. /?. the writer collected at Wahiawa in the north fork of Kau- 

 konahua gulch on Oahu, on May 15, 1909, fruiting no. 3046. The leaves are per- 

 fectly glabrous, and chartaceous, the capsules are larger and also glabrous, even 

 when very young.

A rather small tree, stunted, the young shoots coarsely hirsute; leaves opposite, sub-
