Morphology
This climbing deciduous or semi-evergreen shrub possesses slender, arching branches. The young stems exhibit a fine indumentum that gradually disappears as the wood matures.
Key morphological features include:
- Leaves: Opposite, lanceolate to ovate-lanceolate, with a distinctive golden or yellowish felty coating of hairs on the abaxial (lower) surface.
- Flowers: Solitary and axillary, featuring a tubular-campanulate calyx and a two-lipped corolla.
- Fruit: Small capsules containing numerous tiny seeds adapted for local dispersal.
Interesting facts
The varietal epithet hypochrysa translates to 'golden beneath' in Greek. This directly refers to the striking yellow-gold coloration of the hairs coating the underside of the leaves, which serves as a key identifying marker in the field.
