ANACARDIACEJ1. 359 



Hab. Tahiti : in mountain forests, sometimes in scattered groves. 

 Common also at Tutuila, Navigators' Islands, and at Tongatabu. 



I find no Tahitian specimens in the collection ; but those from the 

 Tonga and Samoan Islands (both in fruit only) accord very well with 

 the character of R. Taitensis, except that in the Samoan specimen 

 the leaflets are occasionally even 6 inches long, and some of them 

 acuminate. The pinnae are often fewer than 10 pairs. The drupe is 

 black, smooth and shining, 2 or 3 lines in diameter. 



3. Knus Sandwicensis, Sp. Nov. 



R. ramulis novellis velutino-tomentosis ; folils pinnatis ; foliolis 5-9 

 [rutins 3) ovatis oblongisve subacuminatis serratis subsessilibus supra 

 glabratis subtus cum rhochi immarginata panicidaque terminali com- 

 posita amplissima tenuiter tornentosis ; floribus parvis. 



Hab. Sandwich Islands : Oahu, in the mountains behind Honolulu 

 (where it was collected by the late Rev. J. Diell) ; and in forests near 

 Hilo, Hawaii. (Byron's Bay, Hawaii, Macrae. Oahu, Gaudichaud.) 



Shrub 4 to 10 feet high, with much the habit of R. typhina; the 

 stout branches warty, smooth, or when developing velvety-tomentose ; 

 the marginless petioles, inflorescence, &c, tomentose with a fine and soft 

 pubescence. Leaves pinnately 5-9-foliolate, or the upper ones some- 

 times trifoliolate. Leaflets oval or oblong, more or less acute or slightly 

 acuminate, ample, from 2 to 6 inches long, and from an inch to 4 

 inches wide, more or less serrate, almost sessile, copiously feather- 

 veined, with 12 to 20 pairs of straight veins, which are prominent on 

 the downy under surface, the upper face nearly glabrous. The leaves 

 considerably resemble those of a Walnut or Butternut. Panicle ter- 

 minal, very large, and compound (sometimes with smaller ones in the 

 upper axils), loose and open, often a foot in diameter, very many- 

 flowered; the flowers small (a line and a half in diameter), apparently 

 yellowish-white, racemosely crowded on the ultimate ramifications. 

 Calyx nearly glabrous, deeply five-cleft; the lobes oblong-ovate, 

 minutely ciliate, not half the length of the oval and minutely ciliolate 

 petals. Stamens 5, rather shorter than the petals. Styles 3, clavate. 



Fruit not seen.
