Colin Mills, compiler of the Hortus Camdenensis, died in late November 2012 after a short illness. As he always considered the Hortus his legacy, it is his family's intention to keep the site running in perpetuity. It will not, however, be updated in the near future.

Isoloma tubiflorum Decne.

Frost tender, perennial, shrubby gesneriad with hairy, ovate leaves, paler beneath, and small, tubular, yellow flowers, tinged with red.  [RHSD].

Horticultural & Botanical History

Introduced to Britain in 1846.  [RHSD].

Only recorded in a handwritten entry in a copy of the 1850 catalogue held at the Mitchell Library and inscribed on the front Wm. Macarthur, 23rd Dec. 1854.  [ML635.9m].


Another, perhaps less likely possibility is Dolichodeira tubiflora Hanst., synonyms for which include Gesneria tubiflora Endl., Achimenes tubiflora Britton, Gloxinia tubiflora Hook., Sinningia tubiflora Fritsch.  From South America, it is a tuberous perennial with downy, slender-pointed, opposite, oblong leaves, and panicles of white flowers, to 3cm across, in summer.  [RHSD].  It is figured in Curtis’s Botanical Magazine and the Botanical Register as Gloxinia tubiflora.  Introduced to Europe in 1815.  [BM t.3971/1842, BR f.1845/1836].
