Close up of flower

Drymocallis glandulosa, formerly Potentilla glandulosa, known by the common names Douglas' wood beauty[1] and sticky cinquefoil, is a plant species in the family Rosaceae.

It is native to western North America from southwestern Canada through the far western United States and California, into Baja California.[2] It is widespread and can be found in many types of habitats.

Description

[edit]

Drymocallis glandulosa is generally erect in form but it may be small and tuftlike, measuring just a few centimeters high, or tall and slender, approaching 1 metre (3.3 ft) in height. It may or may not have rhizomes.[3]

It is usually coated in hairs, many of which are glandular, giving the plant a sticky texture. The leaves are each divided into several leaflets, with one long terminal leaflet and a few smaller ones widely spaced on each side.

The inflorescence is a cyme of 2 to 30 flowers which are variable in color and size. Each has usually five petals up to a centimeter long which may be white to pale yellow to gold.

Varieties

[edit]

It is highly variable and there are many varieties and subspecies, some of which intergrade and are not clearly defined. They include:[4]

  • Drymocallis glandulosa var. glandulosa
  • Drymocallis glandulosa var. reflexa
  • Drymocallis glandulosa var. viscida
  • Drymocallis glandulosa var. wrangelliana

Ecology

[edit]

The plant is more common after its habitat is cleared or disturbed, such as by wildfire, clearcutting, or heavy grazing.[3]

It is an important food for several species of mice, including the western harvest mouse, cactus mouse, and California mouse.[3]
