640 species in 21 genera are found in temperate and tropical regions.

[Summary yet to be added]

Fuchsia L.

100 species are found in New Zealand, Tahiti and central and South America. Several species and countless hybrids / cultivars are of significant horticultural importance because of their showy flowers, being widely grown as ornamentals.

Positive patch test reactions to a hybrid of this genus and also to Streptocarpus were reported by Agrup and Fregert (1968) and Agrup (1969).

Gaura mollis James

(syn. Gaura parviflora Douglas ex. Lehm.)

Velvetweed, Lizard's Tail

In an investigation of "weed dermatitis" Gaura parviflora produced a positive patch test reaction in one of 50 patients tested (Shelmire 1939).

Oenothera biennis L.

Common Evening Primrose

Maiden (1909) received a report that this species produces eczema in humans. It is possible that his correspondent was referring to Primula. Cleland (1914b) also referred to this report.

Oenothera speciosa Nutt.

(syn. Hartmannia speciosa Small)

Pinkladies, Showy Evening Primrose

In an investigation of "weed dermatitis" Hartmannia speciosa produced a positive patch test reaction in one of 50 patients tested (Shelmire 1939).
