Another print, published a bit earlier the same year, can be seen here.
The plant is described in the text, based on information provided by others, as having “flowers springing in clusters from the root”, not unlike the flowering habit of species like Gesneria (now Sinningia) tuberosa. However, as is clear from the pictures of live plants here, the flowers in fact are produced in the conventional way from the leaf axils. This is an unusual error for the usually very careful William Curtis.
