170 MANX, 



1. Z. KAVAIENSE Gray. (Enum. No. 80.) A small, glabrous, and 

 unarmed tree. Leaves alternate, 3 - 5-foliolate ; leaflets membranaceous 

 when young, becoming coriaceous, ovate, acute, li' long, 1' wide, the 

 lateral ones ofteji somewhat unequal. Panicles solitary or fascicled in 

 the axils, shorter than the leaves, loosely few-flowered. Calyx four- 

 lobed; the lobes ovate-subulate, I" long. Petals in the sterile flowers 

 2" long. Stamens four, 1" long. In the female flowers the petals are 

 linear-ligulate, about 3" long, and imbricated in aestivation ; the sta- 

 mens are reduced to 4 glands. Ovary one-celled, stipitate ; stigma 

 globular. Fruit raised on stipes 2" long; the follicles short and tur- 

 gid, 4" - 5" long, somewhat wrinkled and punctate, two-valved from 

 the apex, glabrous. Seed solitary, filling the cell, oval, black, and 

 shining. 



Kauai, on the mountains above 'Waimea. Hawaii. 



2. Z. MAVIENSE H. Mann. (Enum. No. 81.) Apparently an un- 

 armed tree; the young branches, petioles, &c., cinereous with a fine 

 velutinous pubescence. Leaves 3-foliolate, about 2-' long, by li' wide, 

 the lateral ones very unequal, ovate, obtusish, truncate at the base, 

 puberulent above, quite tomentose beneath. Petioles 15" - 20" long. 

 Panicle several-flowered. Flowers unknown. Carpels solitary, ses- 

 sile, 4" -5" long, lunulate-ovoid, becoming 2-valved, dotted externally. 

 Seed solitary, filling the cell. 



" Maui." 



3. Z. (BLACKBURXIA)-:DIPKTALU:M H. Mann. (Emim. No. 82.) A 

 small tree, entirely glabrous. Leaves alternate, 3-7-foliolate, petioled. 

 Leaflets 2' -3' long, 7" -20" wide, oblong or oblong-ovate, obtuse, 

 coriaceous, pinnately veined, equal at the base, and with one or two 

 small (3" -9" long) foliar bodies arising from just below the lower 

 leaflets, which were it not for their anomalous position might be 

 likened to large stipules (are these, however, normal?). Panicles 

 axillary or terminal, cymosely many -flowered, with a very thick and 

 nodose peduncle and axis. Calyx small, less than 1" long, four-lobed. 

 Petals 2, oval, valvate, and remarkably thick, in the bud 3" -4" long, 

 probably caducous. Stamens four; filaments short, subulate ; anthers 

 oblong. Only buds of sterile flowers seen, therefore fruit, &c., un- 

 known. 



To the tropical Order MELIACE^ (which are trees or shrubs with alternate, usually 

 compound leaves, destitute of stipules: a calyx of 3-5 sepals, the same number of petals, 

 and twice as many moiiadelphous stamens, inserted with the petals on the outside of an 

 hypogynous disk: a several-celled ovary, with one or two ovules in each cell, and the 

 styles and stigmas united into one: the fruit a drupe, berry, or capsule, with one-seeded
