Oreocarya roosiorum

Higher Taxonomy
Family: BoraginaceaeView DescriptionDichotomous Key

Habit: Annual, perennial herb, or shrub, often bristly or sharp-hairy. Stem: prostrate-decumbent to erect. Leaf: basal and/or cauline, simple, generally alternate, sometimes opposite, especially at base. Inflorescence: cymes, arranged singly or in groups of 2--5, generally coiled in flower, generally elongating in fruit. Flower: bisexual, generally radial; sepals 5, free or fused at least at base; corolla 5-lobed, salverform, funnel-shaped, rotate, or bell-shaped, appendages (often called "fornices") 0 or 5 at top of tube, when present often differentially pigmented, alternate stamens; stamens epipetalous; ovary superior, 4-lobed, style 1, entire or minutely 2-lobed (2-branched). Fruit: nutlets 1--4, when > 1, all similar (often called "homomorphic") or 1 or 2 dissimilar in size and/or shape from the others (often called "heteromorphic"), free (fused), smooth to roughened, prickly or bristly or not.
Genera In Family: +- 90 genera, +- 1600--1700 species: mostly temperate, especially western North America, Mediterranean; some cultivated (Borago, Echium, Myosotis, Symphytum). Toxicity: Many genera may be TOXIC from pyrrolizidine alkaloids or accumulated nitrates. Note: Sometimes still treated in broader sense of TJM2 (e.g., APG IV 2016 Bot J Linn Soc 181:1--20), but recent evidence (Luebert et al. 2016) supports segregation, for our flora, of the families Ehretiaceae, Heliotropiaceae, Hydrophyllaceae, Lennoaceae, and Namaceae.

Oreocarya roosiorum (Munz) R.B. Kelley, Hasenstab & M.G. Simpson
Habit: Perennial herb 1--2(--3) cm; caudex woody, branched. Stem: +- many, +- >= basal leaves, spreading-soft-bristly. Leaf: basal rosettes generally many; 0.5--1.2(--1.5) cm, oblanceolate to narrow-spoon-shaped, +- thick, gray-green, +- dense-silky-hairy to tomentose, bristles mostly appressed, bulbous-based. Inflorescence: dense, +- head-like, not elongated in fruit; pedicel short-elongated in fruit, 1.5--3 mm. Flower: calyx 2.5--3 mm, 3.5--5(6) mm in fruit, dense-strigose, +- spreading-bristly; corolla late-deciduous, aging +- brown, tube 2--3 mm, limb 4.5--5.5 mm diam, appendages yellow. Fruit: nutlets generally 1--3, 2--2.5 mm, lance-ovate to ovate, +- constricted above, +- dark gray, +- shiny to dull, margin sharp-angled or occasionally rounded; abaxially dense-tubercled with low-rounded wrinkles or papillate, ridge rounded; adaxially tubercled to papillate, attachment scar edges abutted near tip, +- wide-gapped lower 1/2, narrow-triangular, edges not raised; axis beyond nutlets.
Ecology: Rocky, dry meadows in open bristlecone pine-limber pine forest; Elevation: 2570--3230 m. Bioregional Distribution: s W&I (n Inyo Mtns). Flowering Time: Jun--Jul
Synonyms: Cryptantha roosiorum Munz

View all CCH records
All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
