May Appeal 2026
Please help keep TSO growing!
IDS Trees and Shrubs Online has become a fundamental source of reliable information about cultivated woody plants, freely available to everyone, everywhere. We hope you find it useful.
For the first time we are asking our users if you could support us.
If everyone who uses TSO during May 2026 gives just £10, we would cover our costs for a whole year, enabling us to accelerate our work.

Family
- Papaveraceae
A genus of two semi-herbaceous shrubs, both Californian, one extending into Mexico. The leading characters of the genus are the pinnately divided leaves, the large white usually solitary flowers with four to six petals and three soon deciduous sepals, numerous stamens, sessile stigmas connate at the base, capsular appressed bristly fruits splitting by valves and containing numerous small seeds.
The generic name commemorates the Irish astromoner Dr F. Romney Robinson, a friend of Dr Coulter, who discovered the type-species (for further information on the history of the generic name see Bot. Mag., n.s., t. 678).
