Rubiaceae. 

 Var. scoriacea Rock var. nov. 



Branches light gray, terete and striate. Leaves suborbicular, shining, coriaceous, 

 pubescent along the prominent nerves and midrib, on petioles of 2 to 2.5 em; the flat 

 glands triangular and very conspicuous in the axils of the nerves; panicles of 1 to 3 

 whorls, rather short, 2.5 to 3 cm, densely tomentose, with a dirty yellowish-gray tomentum; 

 calyx and corolla pubescent, the former truncate; drupes angled, obovate, rather small, 7 

 mm, pubescent. 



As the name implies, this variety occurs on the scoria or aa lava fields of 

 Manuka in Kau on the southern slopes of Mauna Loa, Hawaii. It is a small 

 tree 15 feet in height and grows in company with Nototrichium sanduticense, 

 Santalum- Freycinetiamim, Osteomeles antliyllidifolia, and others. Collected 

 July, 1911, flowering and fruiting. The type is no. 10201 in the College of

Straussia Fauriei Levi. 

 Eopiko. 



STEAUSSIA FAUKIEI Levi, in Pedde Kepert. X. 10/14 (1911) 155. 



Branches stout; leaves obovate or suborbicular, 3 to 7.5 cm long, 2 to 6 cm wide", 

 rounded or acute at the apex, somewhat contracted at the base, slightly subcordate, sub- 

 gessile or on petioles of 1 mm, reddish to bronze-colored when dry, glabrate, with strong 

 prominent nerves; panicles erect, short, rusty tomentose, peduncle 15 to 25 mm; calyx limb 

 truncate or wavy, corolla lobes twice the length of the tube, puberulous, slightly bearded 

 at the throat; the drupe is obovate, crowned by the calyoine limb and a small conical 

 disc which is not protruding. 



This marked species is a small tree 10 feet or little more in height and occurs 

 on Oahu as well as on Lanai on the crests of the mountain ridges exposed to the 

 wind and cold and therefore appears stunted. The species was first discovered 

 by the writer in the Punaluu Mts., Oahu, on Aug. 23rd, 1908 (no. 25), was 

 again collected on December 3, 1908 (no. 634) ; and also on the Island of Lanai 

 (no. 8047) on the top of the ridges leading to the summit Lanaihale. In the 

 Lanai specimens the leaves are 3x2 cm, while the Oahu specimens have larger 

 leaves. The panicles are usually one-whorled. Collected also by Abbe Faurie 

 (no. 400) at Nuuanu pali, December, 1909.

 Pac. VI. (1890) 197;— K. Schum. in Engl, et Prantl Pflzfam. IV. 4. (1891) 112. 

 Leaves obovate or elliptical oblong, 10 to 12.5 cm long, acuminate, contracted below, 

 triangular, obtuse, 3 mm; panicle furfuraceous-pubescent, erect, short, with 2 to 3 whorls, 

 the peduncle about 2.5 cm; calyx and corolla puberulous in the bud, the latter four to six- 

 lobed, with faint hairs at the throat, the lobes scarcely longer than the tube; stamens 

 4 to 6; ovary semi-superior; drupe slender, ellipsoidal or fusiform, 12 mm long and 4 mm 

 Ibroad at the middle, the conical apex or disc projecting beyond the calycine limb. 



Hillebrand records this species as a shrub from East Maui, woods of Pumelei. 

 The writer collected specimens from apparently this species from West Maui, 

 and also Bast Maui, in open gulches above Makawao, where it is a small tree
