Diplacus aurantiacus
species of flowering plant
Diplacus aurantiacus, the sticky monkey-flower or orange bush monkey-flower, is a flowering plant that grows in a subshrub form, native to western North America from southwestern Oregon south through Northern and Central California. It is a member of the lopseed family, Phrymaceae, and was formerly known as Mimulus aurantiacus.
Description
Diplacus aurantiacus grows up to 1.2 meters (4 feet) tall, has deep green, sticky leaves 3 to 7 centimeters long and up to a centimeter broad and flowering stems that grow vertically. The flowers are tubular at the base and about 2 centimeters long with five broad lobes; they occur in a variety of shades from white to red, the most common color being a light orange. They are honey plants pollinated by bees and hummingbirds.
It grows in many climates and will thrive in many types of soil, wet, dry, sandy, or rocky. It even grows in serpentine, a soil that most plants have difficulty thriving in because of its unique mineral composition.
Diplacus aurantiacus is an important host plant for the larvae of the common buckeye butterfly (Junonia coenia) and the variable checkerspot (Euphydryas chalcedona), despite a phenolic resin in the leaves which deter its feeding. This resin also helps the plant retain water in dry environments.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Diplacus aurantiacus”, the useful work is to connect “species of flowering plant” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 19, 2026. The linked authority identifier is Q3314656. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
