Saxifragopsis fragarioides (Greene) Small strawberry saxifrage Saxifragaceae - saxifrage family status: State Threatened, BLM sensitive, USFS sensitive rank: G3? / S1 General Description: A dapted from Hickman (1993): Glandular perennial with thick, woody, trailing stems; caudex thick, woody, branched, scaly. Leaves mostly basal; a few stem leaves reduced upwards as sessile, linear bracts. Petioles 1.5-4 cm, expanded at the base, membranous. Blades 1.5-4 cm, obovate, tapered at the base, coarsely toothed at the apex, jointed to the petiole and falling from it. Floral Characteristics: Inflorescence a panicle, 10-25 cm, with greater than 40 flowers. Hypanthium partly fused to ovary. C alyx lobes 2-3 mm, spreading to reflexed, elliptic to ovate. Petals 2-3 mm, obovate. Stamens 10. Styles 2, fused at the base when in flower. Flowers June to July. Fruits: C aps ules . Identif ication Tips: This taxon is not treated in Hitchcock & Cronquist (1973). It is the only species of this genus in our range. Saxifraga is similar, but Saxifragops is has leaf blades that are jointed to and falling before the petiole. Its styles are generally fused at the base, at least when in flower, whereas Saxifraga has styles that are free. Range: Widely disjunct in WA ; known from northern C A and southwestern O R. Habitat/Ecology: Cracks and crevices on cliffs and rock outcrops; occasionally in talus. Surrounding forests are dominated by ponderosa pine (Pinus ponderos a) and Douglas-fir (Ps eudots uga menzies ii). Associated species include oceanspray (Holodiscus discolor), mock-orange (Philadelphus lewisii), snowbrush ceanothus (Ceanothus velutinus ), serviceberry (Amelanchier alnifolia), bitterbrush (Purs hia tridentata), s nowberry (Symphoricarpos albus ), field c hic kweed (Ceras tium arvens e), T weedy's lewis ia (Lewis ia tweedyi), beardtongue (Pens temon spp.), and balsamroot (Bals amorhiza s agittata). Elevations in WA : 400-1300 m (1440-4300 ft). The species is adapted to the harsh environment of cracks in rock outcrops and cliffs. Comments: The occurrence of this species in WA constitutes a significant disjunction from the rest of its range. Habitats are generally inaccessible but may be affected by rock climbing, road maintenance, and herbicide applications. This species is rare in O R and uncommon in CA. Ref erences: Hickman 1993.
