Typification.
There are two sheets of
Ekman
H5025 at S. We have selected the sheet with open corollas as the lectotype.
Note.
Very distinct because of the stellate hairs on vegetative parts. The inflorescence has very short hairy peduncles and short pedicels so inflorescence in axillary clusters. The corolla is yellow-green, broadly campanulate and with strongly exserted anthers.
