all the description. We ought, however, to state that Roxburgh in his spe- 
cific character mentions the leaves to be oftener 3- than 5- nerved in his M. 
cajuputi ; perhaps he borrowed this from Rumphius M. minor, supposed b 
him to be the same, for in the description he does not say so. Hamilton (1. 23 
supposes Rumph. Amb. t. 17. f. 2. to be Metrosideros saligna, but that is à 
New Holland plant ; we rather suspect it to be another species of Melaleuca.

Calyx campanulate, 4-6-cleft, cohering with the ovary at the very base: 
lobes acute: sstivation valvular. Petals 4-6, alternating with the lobes of 
the calyx, or wanting. Stamens numerous: filaments distinct: anthers 
roundish. Style filiform. Stigma large, peltate. Fruit baccate, adnate by 
its base to the permanent calyx and thus appearing half superior, nearly glo- 
bose, many-celled : rind membranaceous, cells 10-15, separated by thin dis- 
sepiments. Seeds numerous, nestling in a fleshy pulp, curved. Embryo 
curved: radicle long: cotyledons short, unequal, foliaceous, convolute.— 
Small trees. Leaves opposite, quite entire, thickish, 1-nerved, almost vein- 
less, not dotted. Flowers ternal, usually solitary, large.

Calyx turbinate, 5—7-cleft: sstivation valvular. Petals 5-7. Stamens nu- 
merous: filaments distinct. Style filiform. Stigma capitate. Fruit large, glo- 
bose, crowned by the somewhat tubular limb of the calyx, baccate, indehiscent, 
covered with the tube of the calyx, divided horizontally into two parts by a 
dissepiment : the lower division 3-celled, the upper 5-9-celled ; dissepiments 
membranaceous : placentz in the lower division at the bottom ; in the upper 
stretching from the side of the fruit to the middle. Seeds numerous, nestling 
na pellucid pulp. Embryo oblong: radicle short, acute ; cotyledons folia- 
ceous, spirally convolute.—Small trees or shrubs with spinescent branchlets. 
Leaves deciduous, opposite, rarely verticillate or alternate, often axillary and 
fascicled, oblong, quite entire, not dotted. Flowers 2-3, nearly sessile on 
Somewhat terminal branchlets, usually scarlet. 
This genus onl differs from the other Myrtacee by having two verticels of carpels 
developed aa of one, and perhaps ay truly wild state the upper or adventi- 
ous one may occasionally disappear. The inner series (or those at the bottom of 
ud fruit) have their placentz in the axis ; but the outer series, forced to the top of 
he fruit by the contraction of the mouth of the tube of the calyx, having their pla- 
cente in the ovary at the back of the inner carpels, exhibit them in the ripe fruit in 
a horizontal position on the upper surface of the lower cells.
