FLOEA OF THE HAWAIIAN ISLANDS. 243 



parallel with and close to the margin ; the calyx-tube adherent to the 

 ovary; many stamens; and seeds without albumen. — Many species 

 are aromatic ; cloves are the dried flower-buds of Ganjophyllus aro- 

 maticus ; pimento (allspice) the dried fruit of Eugenia Pimenta, &c. 

 Some species of Barringtonia, which all have very large leaves, flow- 

 ers, and fruits, are cultivated. 



Prult a dry, manj'-seeded dehiscent capsule, • . . , MetbosidebOS. 



Fruit baccate, edible, with numerous seeds in pulp, Psidium. 



Fruit drupaceous, with few or only one seed ripening, Eugenia. 



1. METROSIDEROS Banks. [Ohia lehua.] 



Calyx-tube campanulate or urn-shaped, more or less adnate to the 

 ovary; lobes 5, slightly imbricated. Petals 5, spreading. Stamens 

 indefinite, much longer than the petals, in 1-many series, free. Ovary 

 3-celled ; style filiform ; stigma small or truncate. Ovules very many 

 in each cell, densely covering the placentae, which are at the inner 

 angle of the cell, horizontal or slightly ascending. Capsule loculicid- 

 ally or rarely irregularly dehiscent on the top. Embryo straight. — 

 Trees or shrubs, which are rarely climbing. Leaves opposite or 

 rarely alternate. Flowers usually very showy, in dense di-trichoto- 

 mous cymes which are either terminal or axillary. 



A small genus, mostly of PacLflc Islands and New Zealand. 



1. M. POLYMORPHA Gaud. {Enum. No. 131.) A small or large 

 tree 2° -100° high, with variously shaped leaves, either glabrous, 

 pubescent, or tomentose, and with red or yellow flowei's, and, as the 

 name indicates, taking a great variety of forms, of which the follow- 

 ing are some of the more marked. The leaves not rugose, nor the 

 cymes with large persistent bracts. 



Var. 1. Leaves elliptical or orbicular, more or less cordate at the 

 base and very short petioled, or sessile, obtuse at the apex, often 

 broader than long, i' -Ih' in diameter, finely- canescently-tomentose 

 beneath, glabrous and shining above, crowded and frequently imbri- 

 cated on the branches. Cymes on short or somewhat lengthened 

 peduncles, which with the calyx-tubes are densely tomentose, few- 

 several-flowered. Flowers rather small, bright red. 



Var. 2. Leaves elliptical or oblong, very thick-coriaceous, cordate 

 at the base, obtuse at the apex, on petioles 2" -3" long, more than 1' 

 long, densely tomentose beneath, as are the peduncles and calyxes, or 

 sometimes the leaves nearly glabrous. Flowers larger. 



Var. 3. Like var. 2, but entirely glabrous throughout. 



Var. 4. Leaves coriaceous, oblong, 2' long and tapering to the base 

 into a petiole 4" -6" long, obtusish at the apex, and entirely glabrous. 

 Cymes loosely flowered. The large calyxes tomentose.
