Leaves obovate or obovate oblong, 5 to 10 cm long, 3 to 5 cm wide, on short petioles 

 of 4 to 12 mm or even sessile, rounded or shortly acuminate, cuneate toward the base, 

 chartaceous to coriaceous, with nerves prominent or little prominent, glabrate or puberulous 

 underneath, turning black when dry; stipules short 4 to 6 mm, broadly triangular; panicle 

 4 to 12.5 cm long, erect or nodding, puberulous or glabrate, with only 1 or 2 approximate 

 whorls of rays toward the end of a long peduncle; calyx 1 mm, the limb denticulate; 

 corolla about 4 mm, naked at the throat, its 4 to 6 lobes generally longer than the tube, 

 often 2 to 3 times as long; drupe obovoid or top-shaped, almost quadrangular, with a broad, 

 flat disc, 10 to 14 mm long, and about 8 mm broad near the top. 



This. is a very variable species and occurs mainly in the mountains of the 

 Island of Oahu, where it is quite common. The flowers, which are very small 

 and white, are arranged on rather long drooping panicles ; the drupes are yellow 

 and resemble a coffee-drupe. It is a medium sized or small tree of 15 to 20 

 feet in height, and is often quite stunted and shrubby when growing on the 

 crests of mountain ridges. It occurs on Lanai on the Mahana ridge (no. 8044) 

 in company with Pittosporum confertiftorum, Xanthoxylum, Gouldia, Tetra- 

 plasandra meiandra, and others. 



The wood being whitish, it is called Kopiko kea by the natives. Hillebrand 

 records is also from Molokai ; he enumerates two varieties which are here in- 

 cluded in the species. A very interesting new species was found by the writer 

 when in company with Mr. G. P. Wilder, in Nuuanu Valley, Oahu, and is de- 

 scribed as follows. 



Straussia longissima Rock sp. nov. 

 (Plate 185.) 



Leaves obovate-oblong, acute at the apex or rounded, strictly cuneate at the base, 

 sessile or on petioles of 2 m, 2 to 15 cm long, 4 to 8 cm wide, light green above and 

 glabrous, with prominent strong nerves and midrib, which, like the whole underside of 

 the leaves, are covered with a rufous pubescence; stipules broadly triangular to oblong, 

 acute; panicles exceedingly long up to 25 cm, pendulous, the common peduncle up to 18 em 

 long, the shortest 10 cm, with three whorls, each of four rays, the whole inflorescence in- 

 cluding peduncle rufous pubescent; calyx limb truncate to dentate, pubescent, corolla small 

 2.5 mm, white, naked at the throat, the 4 lobes as long as the tube, glabrous; drupe obovoi'd 

 to oblong 12 to 14 mm long, 6 mm wide, with a small conical disc, not ribbed.
