haud visus.) — Arbor procera, inermis; foliis exstipulatis jnnnatis 

 5-7-foliolatis subtus incanis; umbellis decompositis paniculatis* 



I. Tetraplasandra Hawaiensis, Sp. Nov. (Tab. 94.) 



Hab. Hawaii, Sandwich Islands ; in the district of Puna. 



" A fine tree, 30 or 40 feet high, with the trunk a foot in diameter," 

 • unarmed. Branchlets, with the leaf-stalks, inflorescence, and the 

 exterior of the flowers canescent w r ith a close and soft tomentum, 

 glabrate with age. Leaves alternate, destitute of stipules, large (the 

 stout petiole with the rhachis a foot or two in length), pinnately 5-7- 

 foliolate. Leaflets oblong or elliptical, from 4 to 7 inches long, and 2 

 inches or more in width, obtuse at both ends or acute at the base, 

 entire, coriaceous, glabrous above, densely canescent-tomentose under- 

 neath, pinnately veined from a stout and salient midrib, petiolulate. 

 Peduncle terminal, stout, bearing an ample and open panicle of com- 

 pound or decompound umbels. Bracts caducous. Peduncles and 

 pedicels articulated ; the latter about an inch long. Flowers probably 

 polygamous, large for this order; the buds nearly half an inch long 

 and 4 or 5 lines in diameter. Calyx naked at the base (not involu- 

 cellate) ; the tube hemispherical, adnate; the truncate limb very short, 

 entire, or obscurely repand, persistent. Corolla epigynous, ovoid- 

 hemispherical in the bud, 3 or 4 lines long, of 7 or 8 triangular- 

 oblong valvate petals, lightly cohering, especially by their inflexed tips, 

 sometimes apparently separating, but usually caducous in the form of 

 a calyptra. Stamens 28 or 32, four times as many as the petals, and 

 inserted with them, in a single series, on the margin of the epigynous 

 disk : filaments short, filiform, about the length of the anthers, which 

 are sagittate-oblong, fixed by the middle, incumbent, two-celled ; the 

 cells opening longitudinally. Ovary 7-10-celled; the apex crowned 

 with a short and conical stylopodium, bearing a depressed, undivided, 

 obscurely 7-10-myed stigma. Ovules solitary and suspended from the 

 summit of each cell, anatropous. Fruit a globular baccate drupe, 5 

 lines in diameter, containing 7 to 10 compressed and coriaceous 

 pyrencB. Seed suspended. Albumen fleshy. Embryo not seen.
