Rules for naming hybrids (pdf)

For assistance or for more information on registering gesneriads, email Irina Nicholson.

This is the start of a project to put the registered gesneriads information online. Please check back often.
Underlined IR numbers link to photographs of the plants. The photos are in most cases the official registration pictures submitted by the hybridizers (when available). The underlined hybrid name links to the official description.

The Gesneriad Society periodically publishes and updates information which is essential to hybridizers and anyone interested in identifying characteristics of gesneriads they may be growing. The Register series are checklists that contain every published and known cultivar name up to the date of publication. Ordering information for the Gesneriad Registers may be found here.

The listings have been divided into several sections by genus:

A - H | I - P | Q - Smithiantha| Streptocarpus | T-Z | Numerical Reference(1957-1999)
Numerical Reference (2000-2005) | Numerical Reference (2006-Present)
