Now known as Kohleria hirsuta.
In the accompanying text, particular note is made of the “soft down with which its leaves and stems are clothed”, with the note that this is the subject of the specific name “mollis” — meaning soft. It also notes that it’s growth habit is not at all “soft”, and that the species can grow upwards of 5 feet, or 1.5 meters.
K. hirsuta (another name that’s the result of the downy/hairy character of the species) is a highly variable species. Another print can be seen here, and photos of plants can be seen here.
