Myrsinaceae. 

 Suttonia Knudsenii Rock sp. nov. 



A small tree or shrub, branches tortuose, glabrous; leaves ovate to obovate, or subor- 

 bicular, glabrous on both sides, venation prominent, reticulated, the margins revolute, 

 quite opaque, sparingly punctate underneath, dark green, with glaucous hue, shining above, 

 dull beneath, quite chartaceous, 4.5-7 cm long, 3-4.5 cm wide, on petioles of 2-4 mm; 

 inflorescence fasciculated at intervals of 15 mm along the slender branchlets and in the 

 axils of the leaves, of 3-12 flowers, puberulous, pedicels of 2-2.5 mm, the bracts 1 mm, 

 triangular, with ciliate margins; calyx 2 mm, parted more than half its length into acute 

 lobes, densely punctate, with fimbriate margins, corolla twice as long as the calyx, orna- 

 mented with dark dots, anthers oblong, puberulous at the apex, ovary ovoid, with distinct 

 style; fruit unknown. 



This exceedingly handsome species is peculiar to the Island of Kauai and is 

 only found in the forests of Halemanu, in the interior swampy woods ; it is dis- 

 tinguished from the other Suttonias by its thin leaves which are ovate to suborbi- 

 cular and are of a glaucous color, and in the very shortly pedicellate red flowers. 

 It is a striking species and is here named for Mr. Augustus Knudsen, of Waiawa, 

 Kauai, to whom the \vriter is greatly indebted for extended hospitality and 

 facilities for collecting in the mountains of Kauai. The type is number 2337 

 in the College of Hawaii Herbarium. Collected February 14-26, 1909, Hale- 

 manu, Kauai, flowering. 



A form with somewhat smaller leaves, which are acute at the apex instead 

 of rounded, and more elliptical in outline, must be referred here as forma 

 elliptica'hn. nov. (no. 1661), flowering, February, 1909, Halemanu, Kauai. 



Suttonia Hillebrandii Mez. 

 Kolea. 



SUTTONIA HILLEBKANDII Mez Das Pflzenreich 9. IV. 236. (1908) 337. 



Branches entirely glabrous, leaves on petioles of about 3 mm, acute at the base, 

 shortly contracted, quite acuminate at the apex, rarely somewhat obtuse, about 50 mm 

 long, 20 mm broad, not punctate; inflorescence 5 or more flowered, 10 mm long, pedicels 

 slender, glabrous, 7 mm long sepals 1/3 connate, the lobes ovate somewhat acute, the 

 margins remotely dentate and ciliate, lineate; ovary globose, stigma thick capituliform. 



This species, which is not known to the writer, was collected by Wawra on 

 the Island of Kauai, evidently at Halemanu. There are several forms found 

 on the Island of Oahu which are certainly referable to this species; some of 

 them are varieties. 



On the Island of Oahu in the Koolau range, Mountains of Waikane, the 

 writer collected specimens of a tree which is a good variety and may be de- 

 scribed as follows: 



Var, emarginata Rock var. nov. 



A small tree; leaves lanceolate oblong, glabrous throughout, chartaceous, 3.5 to 

 8 cm long, 12 to 15 mm wide, contracting at the base into a slightly margined petiole of 

 2 to 3 mm, veins prominent; intramarginal nerve continuous and very close to the edge, 

 rounded at the apex and always emarginate; dark green above, lighter beneath; in- 

 florescence in the axils of the leaves and along the branchlets, 3 to 8 flowered, pedicels 

 slender, puberulous, as are the petals, which are sparingly punctulate with reddish dots 

 or even lined; stamens oblong, little shorter than the petals; ovary ovoid, style distinct; 

 fruits large, black, 8 to 9 mm in diameter.
