plant. Leaves opposite and, indeed, united in pairs by the 
dilated and stipulated bases of the petioles which form a kind of 
cup around the branch; these leaves are often a foot or more 
long (including the petiole of about two inches), lanceolate but 
broader upwards, acuminated, in our living plant often spotted 
with blistery swellings, alternate at the base, penninerved. Pe- 
_ duncle often as long as the leaf, axillary, compressed or flattened 
and dilated upwards, when it bears an involucre of two large 
subovate and two smaller lanceolate leaves: within which, upon 
the convex disc of the petiole, is a dense capitate umbel of nume- 
rous greenish yellow. Pedicels short, bibracteate. Calyx very 
thin and membranous, diaphanous, cut half-way down into five 
narrow acuminated appressed segments. Corolla funnel-shaped, 
the limb campanulate, divided into five nearly equal erect slightly 
imbricating ovato-cordate acute segments. Stamens varying in 
length at different periods of the inflorescence, when fully de- 
veloped twice or thrice longer than the corolla. Filaments gla- 
brous: anthers oblong, sagittate ; style rather longer than the 
stamens: stigma two-lobed. Capsule oblong, two-celled.
