A small tree, with stiff branches; leaves crowded near the ends of the branches, 

 chartaeeous to thick coriaceous, the upper side wrinkled with a close net-work, the lower 

 side pubescent or glabrous when old, obovate to spathulate, or oblong, rounded at the apex 

 or bluntly acuminate with revolute margins, 7 to 10 cm long, 2.5 to 3 cm wide on a 

 petiole of 15 to 20 mm; inflorescence terminal, axillary or cauline, short tomentose, the 

 thick peduncle about 2 to 10 mm long, the flowers subsessile; sepals ovate tomentose, 4 

 mm, corolla cream-colored, the tube short, 6 mm, its lobes half as long; stamens half the 

 length of the tube; ovary tomeutose, style of the same length as ovary, the two lobes 

 of the stigma spreading; capsule quadrangular to oblong, tomentose, flattened, about 25 

 mm each way, with a longitudinal median groove; seeds rough, dull. 



This species occurs on the island of Hawaii in the scrub forest at an elevation 

 of 2000 feet and again in the scrub forests or open country at 7000 feet eleva- 

 tion. On Maui the writer collected specimens on the lava fields of Auahi, dis- 

 trict of Kahikinui, southern slopes of Haleakala at an elevation of 1500 feet, 

 which belong to this species. It differs from the Hawaii plants in the leaves 

 only; which are of much thinner texture, being chartaeeous and having rather 

 indistinct veins, while in the plants from Kona and Kau, Hawaii, the veins are 

 very strong and prominent. The specimen figured came from East Maui, 

 southern slopes of Haleakala, where it grew on the rough aa flows along the gov- 

 ernment road. It is a small tree, 15 to 18 feet in height, with a small trunk 

 about 5 inches in diameter.

A loosely branching tree; leaves crowded at the ends of the stiff stout branches, 

 coriaceous, closely areolate above, elongate-obovate or cuneate 15 to 20 cm long, 5 to 7.5 

 cm wide, rounded or shortly apiculate, gradually narrowing into a petiole of 12 mm, pale 

 green, densely covered underneath with a soft fawn or pale lemon colored tomentum; 

 flowers cauline on the bare branches below the leaves, peduncle 4 to 8 mm, bearing at the 

 end 8 to 12 subsessile flowers; bracts 5 mm; sepals 3 mm, ovate obtuse, tomentose; corolla 

 cream colored, with a tube of 8 to 10 mm; stamens half as long, with sagittate anthers; 

 ovary tomentose, the stigma capitate, 2-lobed; capsule thick woody, the flattened valves, 

 with a median furrow and transverse waves 18 to 25 mm, with the endocarp pale orange; 

 seeds flat angular, crenulate or tubercular at the back and edges. 



A tree 30 feet in height, with a trunk of 8 to 10 inches in diameter. It was. 

 first collected by H. Mann on the Waianae range, on Mt. Kaala, and by Hille- 

 brand in Makaleha Valley of the same range.
