Rorana. SALICARIE A. 308 
deciduous, sometimes wanting. Stamens inserted a little below the 
petals, equal in number to them, or 2-3—4-times as many, rarely fewer : 
anthers introrse, bilocular, bursting longitudinally. Ovarium superior, 
2-4-celled : ovules numerous : style usually filiform, rarely very short: 
stigma usually capitate. Placente in the axis. Capsule membranous, 
surrounded by but not combined with the calyx; usually l-celled by 
the obliteration of the dissepiments, bursting longitudinally or irregu- 
larly. Seeds numerous, small. Albumen none. Embryo straight: 
radicle next the hilum: cotyledons flat and foliaceous.— Herbs, shrubs, 
or trees, with usually tetragonal branches. Leaves opposite or (sel- 
dom) alternate, entire, exstipulate, and without glands. Flowers bi- 
sexual. 
TRIBE I.—LYTHREJE. 
Lobes of the calyx during estivation more or less distant or somewhat valvate. 
Seeds wingless.—Shrubs or herbaceous plants. 
I. ROTALA. Linn. 
Calyx membranaceous, tubular, 3-5-lobed ; lobes ovate, acute ; sinus with- 
out accessory teeth. Petals obovate, minute, as long and as numerous as the 
calycine lobes. Stamens as many as the petals, inserted on the middle of the 
calyx-tube. Ovary 3-celled. Style very short. Stigma capitate. Capsule 
covered by the calyx, 1-celled, 3-valved, many-seeded. Seeds compressed, 
smooth and even, shining.—Small herbaceous plants. Leaves sessile, patu- 
lous. Flowers axillary, solitary, minute.

We have the authority of the Missionaries’ and the Banksian herbarium for 
considering this to be the plant of the Mantissa and of Willdenow, although 
in the numerous flowers examined by us we have constantly found 5 lobes 
to the calyx and as many petals and stamens. We presume, therefore, that 
ir number varies from 3 to 5. R. mewicana, Cham. and Schlecht., is de- 
scribed with 3 calycine teeth; R. decussata, DC., if indeed it belongs to the 
genus, has either 3 or 5 teeth, and no petals. 
II. AMELETIA. DC. 
Calyx campanulate-tubular, 4-cleft ; the lobes ovate, very acute, converg- 
ing ; each sinus with a small tooth-like process. Petals none. Stamens 4, in- 
serted on the tube of the calyx. Ovary ovate, 2-celled. Style filiform. Stig- 
Ma capitate. Capsule ovate, 2-celled, 2-valved, septifragal, many-seeded.— 
Herbaceous creeping plants. Leaves opposite, obovate, nearly sessile. Flo- 
riferous branches axillary, forming small bracteated spikes. Flowers distinct- 
ly bibracteolated, sessile, solitary in the axils of the elongated bractese.
