An erect, branching shrub, 4 or 5 feet high, with the

or ovate-lanceolate, acuminate, penninerved, minutely serrulate,
with somewhat bristly ascending teeth ; varying from
2 to 4 inches in length, and from an inch to an inch and a
half, or even more, in breadth, grass green and scabrous on
both surfaces with minute papillose bristles, especially on
the veins, the under surface scarcely if at all paler. Petioles
very short, 2 or 3 lines long, slightly compressed, united
a t the base into a ring, marked above with a narrow furrow.
Flowers cymose. Cymes axillary, solitary, mostly 3-flowered,
or disposed along a terminal axis, like a raceme, and then
they are reduced to a single flower. Bractes opposite, linear-
lanceolate, acute, entire, or sparingly denticulate, channelled,
deciduous. Pedicels filiform, and as well as the calyx, copiously
scabrous and canescent, with starry pubescence.
Calyx the tube globose ; limb urceolate, 5-lobed ; lobes
short, ovate, acute, pale green, erect and connivent. Petals
5, pure white, thrice longer than the calyx, oblong-lanceolate,
somewhat acute, erect and slightly connivent, valvate in
æstivation, the margins slightly induplicate, and erosely
crenulate, especially towards the apex, sparingly clothed on
