Common Name: ORCHID FAMILY Habit: Perennial herb, terrestrial [growing on other pls], non-green (nutrition from association of roots with fungi) or green, generally from rhizomes or tubers with few to many fleshy to slender roots; cauline leaves +- reduced to sheathing stem bracts or not. Leaf: 1--many, basal to cauline, linear to +- round, alternate to opposite (if only 1 pair), generally sessile. Inflorescence: flowers 1--many, spike or raceme, bracted. Flower: bisexual, bilateral, in bud generally rotating 180° by twisting ovary (position of parts indicated after twisting); sepals generally 3, generally free, generally petal-like, uppermost generally erect, lateral with chin- or spur-like projection (mentum) or not; petals 3, 1 (lip) different, spurred or not; stamens generally 1 (3 in Cypripedium, 2 functional, 1 a staminode), fused with style, stigma into column, pollen generally lumped, generally removed as unit by insect; ovary inferior, 1-chambered, placentas 3, parietal, stigma 3 lobed, generally under column tip. Fruit: capsule. Seed: many, minute. Genera In Family: +- 800 genera, +- 25000 species: especially tropics (worldwide except Antarctica). Many cultivated for ornament, especially Cattleya, Cymbidium, Epidendrum, Oncidium, Paphiopedilum; Vanilla planifolia Andrews fruits used to flavor food. Note:Platanthera may be paraphyletic without inclusion of Piperia (Bateman et al. 2009 Ann Bot 104:431--445); study needed. eFlora Treatment Author: Ronald A. Coleman, Dieter H. Wilken & William F.

Common Name: BOG-ORCHID Habit: Rhizome tuber-like, elongate. Leaf: cauline, alternate, linear to elliptic or lanceolate, gradually reduced upward, with 1 lengthwise fold. Inflorescence: generally spike; flower bracts leaf-like. Flower: perianth white to yellow-green or green; sepals +- equal, upper generally hood-like, lower free, generally spreading; lateral petals generally erect, lip spurred, pendent to upcurved; column +- erect. Fruit: ascending to erect. Etymology: (Greek: wide anther) Note: Identification often difficult due to intermediates, hybrids; additional species expected in California. Platanthera hyperborea (L.) Lindl. not in California. Unabridged Note: In California, > 1 sp. often occurs in a given area and blooms at +- the same time, yielding many hybrids and hybrid swarms, including some that have not been named, e.g., Platanthera dilatata × Platanthera tescamnis, as well as others that have, e.g., Platanthera ×estesii W.J. Schrenk (Platanthera dilatata × Platanthera stricta) and Platanthera ×lassenii W.J. Schrenk (Platanthera dilatata × Platanthera sparsiflora). Some purported hybrids, e.g., Platanthera ×correllii W.J. Schrenk and Platanthera ×media (Rydb.) Luer, now treated as a synonym of Platanthera huronensis (Nutt.) Lindl., do not occur in California. eFlora Treatment Author: Ronald A.

Platanthera sparsiflora (S. Watson) Schltr.
NATIVE Habit: Plant 25--55 cm. Leaf: 4--15 cm, 5--30 mm wide. Inflorescence: generally 15--40 cm, dense to +- open, lowest flowers generally not overlapping. Flower: perianth yellow-green to green; sepals 5--9 mm; lip 6--10 mm, linear to lance-linear, spur +- = lip, +- cylindric, +- curved, tip acute; column generally 2.5--4 mm. Chromosomes: 2n=42. Ecology: Full sun to partial shade, wet meadows, streambanks, seeps, conifer forest; Elevation: 100--3400 m. Bioregional Distribution: NW (exc NCoRI), CaR, SN, SCo, TR, MP, D; Distribution Outside California: to Oregon, Utah, New Mexico, Baja California.

MAP LEGEND 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.
