640 species in 21 genera are found in temperate and tropical regions.
[Summary yet to be added]
- Fuchsia Plum. ex 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).
- Ludwigia repens J.R.Forst.
- [syn. Ludwigia natans Elliott]
- Creeping Primrose-Willow, Larger Marsh Purslane, Kriechendes Heusenkraut, Schwimm-Heusenkraut
[Information available but not yet included in database]
- Oenothera biennis L.
- Common Evening Primrose
Maiden (1909b) received a report that this plant can produce eczema in humans. Cleland (1914) also referred to this report.
- Oenothera curtiflora W.L.Wagner & Hoch
- [syns Gaura mollis E.James, Gaura parviflora Douglas ex. Lehm.]
- Lizard's Tail, Small-Flowered Gaura, Velvetweed
In an investigation of "weed dermatitis", an extract prepared from Gaura parviflora produced a positive patch test reaction in one of 50 patients tested (Shelmire 1939a). Shelmire (1940) subsequently described the plant as an infrequent sensitiser.
- Oenothera speciosa Nutt.
- [syns Hartmannia speciosa (Nutt.) Small, Xylopleurum speciosum (Nutt.) Raim.]
- Pinkladies, Showy Evening Primrose
In an investigation of "weed dermatitis", an extract prepared from Hartmannia speciosa produced a positive patch test reaction in one of 50 patients tested (Shelmire 1939a). Shelmire (1940) subsequently described the plant as an infrequent sensitiser.
