 Soc. Linn. Paris. I. "(1880)240. — L. fagraeoidea Hbd. PI. Haw. Isl. (1888) in part. 



Leaves subsessile, thick leathery, oblong, or lanceolate oblong, acute at the apex, 

 cuneate at the base, 7.5 cm to 12.5 cm long, pale underneath, veins transparent, stipules 

 united, tubular, long; sepals oblong-lanceolate, capsules 5 mm high, minutely pedunculate 

 or sessile in the axis of the last leaves within the stipules, three-valved. 



This species which is certainly distinct from L. fagraeoidea, is a tree often 35 

 to 40 feet in height, but occasionally a shrub, and occurs only in the rain forests 

 of Oahu, on the main range. It is especially common in I\Tanoa Valley at an 

 elevation of 2500 feet. It can easily be recognized by its oblong-lanceolate pale 

 green foliage and transparent venation. The capsules are exceedingly small and 

 hidden in the stipules.

A small tree 6 to 8 m high, with slender aud pale terete branches; leaves elliptical 

 or obovate or ovate-oblong, 5 to 10 cm long, 18 to 37 mm wide, on petioles of 4 to 12^ mm, 

 acute or acuminate at both ends, or obtuse at the apex, chartaeeous glabrous-; flowers 

 many in a paniculate cyme 3.5 to 10 cm in length, with a pedvmole of 12 to 30 mm in 

 length, the ultimate pedicels 6 to 18 mm, subequal; bractlets subulate; calyx 3 mm, divided 

 beyond the middle into 5 triangular acute lobes; corolla greenish, very slender, salver- 

 shaped, the tube 6 to 8 mm, glabrous, but pubescent within, the lobes about one-third as 

 long; capsules globose, short, ovoid, or obovoid somewhat obtuse or acute, 8 to 12 mm long, 

 slightly sulcate, 2 valved or very rarely 3-valved, the valves rounded at the back. 



This species is a small tree of 15 to 20 feet or more in height and occurs on 

 Kauai, Maui, Lanai, Molokai, and according to Hillebrand also on Oahu; as it is 

 found on these various islands at different altitudes it is somewhat variable. 

 The trunks of the trees are straight, especially in the specimens from the forests 

 above Makawao (no. 8616). The bark resembles very much that of the Aalii, 

 Dodonaea viscosa, or that of Styphelia tameiameia. It is of a dark brown color, 

 and is closely and deeply corrugated, the furrows are not straight, but seem to 

 encircle the trunk, somewhat cork-screw fashion. The peduncle varies consider- 

 ably in length, as do also the leaves in size. On Lanai the tree was observed on 

 the dry forehills of Mahana and Kaiholena Valleys, (no. 8000 and no. 8099). 

 On West Maui it grows above Kaanapali at 2000 feet elevation (no. 8169). It is 

 typical of the drier regions and hardly ever ascends into the rain forest. It 

 comes very close to L. triflora Hbd. and seems to differ from the latter in not 

 having cordate and subsessile leaves. On Kauai, along the trail to Opaiwela 

 stream near Kaholumano it grows as a shrub; the leaves are larger and the 

 capsules ovoid, acute.
