Characteristics:
Diverse-leaved cinquefoil is a perennial with several spreading
to erect stems from 5-30 cm high (usually less than 30 cm high) and fan-like
leaves. The herbage is eglandular-pubescent. The leaves are mostly basal and
usually are palmately lobed (occasionally somewhat pinnately compound) with
5-7 leaflets. The petiole ranges from 2-6 cm long and the oblanceolate to obovate
leaflets range from about 1-2.5 cm long. The middle leaf let is usually the
longest. The margins consist of shallow to deeply toothed leaf edges, generally
on the upper half of the leaf. The leaf surface is often a glaucous-blue color
(See photo below.), but may also be somewhat haired to glabrous and green.
Diverse-leaved cinquefoil is so named as the leaves are extremely
variable in terms of hairiness, whether the leaf is palmately or subpinnately
divided, and into the depth of the lobes or teeth on the leaflets.
The inflorescence is a many-flowered open cyme which is villous-haired
to eglandular-hairy.The hypanthium is saucer-shaped. The 5 sepals are ovate
to deltate-lanceolate in shape and range from 3.5-5.5 mm long with pointed tips.
The yellow petals are oblanceolate to obovate in shape, and range from 4.8-
8.5 mm long with rounded, truncate, retuse tips. The stamens number 20, and
there are numerous pistils.
Habitat:
Diverse-leaved cinquefoil may be found on dry rocky, windswept
ridges and in open woods. It is most often found between the elevations of 2700-3500
meters.
Range:
Diverse-leaved cinquefoil may be found from southern British
Columbia south through Washington and Oregon (from the Cascade crest east) to
eastern California and east to western Montana and hence south through Colorado,
Utah, Arizona, and New Mexico.

Close-ups of the leaves of what might be diverse-leaved cinquefoil (or is this a very fine-leaved P. gracilis var. fastigiata ?) as seen on a serpentine bald along the Canyon Mountain Trail #218, Strawberry Mountain Wilderness.........June 21, 2011.
The photo above shows the underside of the
hypanthium of diverse-leaved cinquefoil with the sepals, which are shorter than the petals. Also shown at righ is the glaucous leaf of diverse-leaved cinquefoil which is most often
toothed on the upper half of each leaflet in comparison with the similar leaf of slender cinquefoil Potentilla gracilis, which has leaflets toothed along the entire margin.

The photos above show two views of what might be diverse-leaved cinquefoil (or is it Potentila gracilis var. fastigiata ?) as seen in wet meadows along Hat Pt. Road at Memaloose in Hells Canyon National Recreation Area........July 27, 2007. These plants are a bit more robust and are more glabrous (and thus much greener)than those seen at the Steens Mt. above.
