MjTtaceae. 



Leaves small, suborbieiilar, cordate, subsessile, pale green or yellowish, glabrous on 

 both faces; inflorescence and calyx densely tomentose or white woolly, the lobes green, 

 pubescent, with ciliate margins, red-punctate on the outer face, petals glabrous; leaves 

 often slightly pubescent when young. 



t Large trees found on Kauai, above "Waimea, (no. 2044). 



Leaves large, ovate oblong, shortly petiolate, the petioles and part of leaf-midrib 

 pubescent, thick coriaceous, subcordate at the base; young branches and inflorescence 

 covered with a white pubescence; calyx, sepals and petals white tomentose or woolly, the 

 latter showing the red through the white pubescence, the margins white ciliate. 



r. Trees, at high elevation 6000-7000 feet. Mt. Haleakala, Maui, (no. 8593). 



Brandies stout, stiff and gnarled, scaly; leaves small, thick coriaceous, suborbioular, 

 cordate, sessile, or aurieulate at the base; inflorescence densely and thickly white woolly, 

 as are the pedicels and calyx lobes, petals red, glabrous, the margins only white ciliate. 



6 Trees, main ridge of Mahana, Lanai, (no. 8055). 



Leaves ovate, or suborbicular, cordate at the base, thin, subcoriaceous, entirely 

 glabrous on both faces, very shortly petiolate; calyx slightly or thinly pubescent, of a dark 

 silvery or dirty gray color, sepals green and puberulous or glabrous; petals and stamens 

 yellowish, or salmon pink, the former glabrous with slightly ciliate margins; here also 

 belongs a form with longer petiolate leaves, which are suborbicular and cordate, pale 

 green; calyx and sepals densely white woolly, petals large, yellow, glabrous, with ciliate 

 margins; the petioles pubescent. 



Sect. ni. Tomentosae. 



I Trees at 4000-9000 feet elevation Kilauea, Hawaii, also Oaha, Pauoa Val- 

 ley (no. 722) ; Hualalai, Hawaii (no. 3626). 



Leaves large orbicular, cordate at the base, coriaceous, glabrous above, or finely 

 pubescent, tomentose underneath of a dirty gray color, petioles short, tomentose, inflores- 

 cence and calyx pubescent; often yellow flowered. 



K Creepers from the summit swamp of Kohala, Hawaii, (no. 8414). 



Leaves small, orbicular, emarginate at the apex* cordate at the base, sessile, glabrous 

 above, densely covered underneath with a yellow strigose pubescence; inflorescence, calyx 

 and sepals with yellowish strigose hairs, petals red, slightly pubescent, margins ciliate. 



yhe Ohia lehua is the most prevalent tree in the forests of the islands of the 

 Hawaiian archipelago. It can be found from sea-level to an elevation of 9000 

 feet. It certainly deserves its specific name polymorpha as it is the most vari- 

 able tree which the Islands possess. On the summits of Kohala, Hawaii, Mt. 

 Waialeale on Kauai, and Puukukui, West Maui, which have an elevation rang- 

 ing from 5000-5600 feet, it is a creeper, only a few inches in length, though 

 flowering. It grows in company with native violets, geraniums and sundews 

 (Drosera longifolia) while in the middle forest zone it becomes a giant of often 

 100 feet in height, with a trunk of several feet in diameter. At the seashore, as 

 for example at Napoopoo, Hawaii, it is a stunted gnarled tree 10-15 feet in height 

 growing on ancient pahoehoe lava in company with Reynoldsia sandwicensis, 

 the Ohe kukuluaeo of the natives, and other trees. On the windward side of 

 Hawaii, not far from Hilo, it covers the vertical cliffs down to the water's edge, 

 but does not attain any size. Its best development and the largest forests 

 composed of this tree are found on the volcanic slopes of Mauna Loa and Mauna
