Horticultural & Botanical History

‘A very variable species, with the habit of Tupa or Siphocampylus, to which latter genus Don refers it without hesitation.  In our present specimens the leaves are crowded, broadly lanceolate, acuminate, wrinkled, more or less downy, especially the upper ones.  The flowers do not extend much beyond the length of the leaves.  Or L. lanceolata and angulato-dentata (supra, p.301.) and L. ovalifolia (supra, p.299), belong to the same group with the present, and may possibly be forms of the same species: but if so it is the most variable with which we are acquainted.’  [Botany of Captain Beechy’s Voyage p.437/1841].  Introduced to Britain in 1825.  [JD].
