(For a list of species in Camissonia, use the above link.) Jepson Manual glossary definitions can be seen by moving your cursor over words underlined with dots. 1. Inflorescence spike  1. In flowering plants excluding Asteraceae, Cyperaceae, Poaceae, and some other groups, an unbranched inflorescence in which the flowers are sessile and nearly always open from the bottom to the top of the inflorescence. 2. In Asteraceae, Cyperaceae, Poaceae, and some other groups, a spike-like inflorescence is one in which the inflorescence units (e.g., heads in Asteraceae; spikelets in Cyperaceae and Poaceae), instead of individual flowers, are sessile and attached directly to the main axis of the inflorescence, not to branches, and in which floral development may or may not proceed as in 1. or raceme  In flowering plants excluding Asteraceae, Cyperaceae, Poaceae, and some other groups, an unbranched inflorescence in which the flowers are borne on pedicels and nearly always open from the bottom to the top of the inflorescence. 2. In Asteraceae, Cyperaceae, Poaceae, and some other groups, a raceme-like inflorescence is one in which the inflorescence units (e.g., heads in Asteraceae; spikelets in Cyperaceae and Poaceae), instead of individual flowers, are stalked and attached directly to the main axis of the inflorescence, not to branches, and in which floral development may or may not proceed as in 1. ; pedicel  Stalk of an individual flower in an inflorescence, or the corresponding structure in fruit. in fruit ± 0–15 mm; sepals all separating when flower opens 3. Plant ± open, sparsely spreading-hairy, sparsely glandular-hairy; leaves not clustered at base; pedicel in fruit ± 0–5 mm ..... subsp. gilmanii 3' Plant compact, densely spreading-hairy, sparsely glandular-hairy; leaves clustered at base; pedicel in fruit 3–15 mm ..... subsp. kernensis 2' Petals 1.8–4 mm; sepals <= 3.8 mm; stigma surrounded by anthers 4. Leaf ± entire  Having margins that are continuous and smooth (i.e., without teeth, lobes, etc.). ; plant ± glabrous or minutely strigose  With stiff, straight, sharp, appressed hairs. , generally sparsely glandular-hairy, rarely sparsely spreading-nonglandular-hairy ..... C. parvula 4' Leaf serrate  Having margins with sharp, fine to coarse teeth generally pointing tipward, not outward; margins with such teeth on such primary teeth are doubly serrate. or minutely so; plant hairs generally spreading  Oriented more or less perpendicularly to the axis of attachment; often, more or less horizontal. , some glandular 1' Inflorescence spike; pedicel in fr ± 0; sepals generally remaining fused in pairs when flower opens 6. Stigma exceeding anthers; sepals 3–8(12) mm; petals (3.5)5–15 mm 7. Leaf lanceolate  Narrowly elongate, widest in the basal half, often tapered to an acute tip. to narrowly ovate  Egg-shaped (i.e., widest below the middle) in two dimensions (i.e., in one plane), as a leaf. or elliptic  In the shape of a flattened circle or ellipse; wider than linear , ± entire; sepals < 4.2 mm ..... C. sierrae subsp. sierrae (2) 7' Leaf linear  Elongate, with nearly parallel sides; narrower than elliptic or oblong. to narrow-elliptic or -oblanceolate, minutely to coarsely serrate; sepals 3–8(12) mm ..... C. campestris 8. Stem generally erect  Upright; vertically oriented. ; leaf  Organ arising from a stem, generally composed of a stalk (petiole) and a flat, expanded, green, photosynthetic area (blade); distinguished from a leaflet by the presence in its axil of a bud, branch, thorn, or flower; sometimes with lateral, basal appendages (stipules); either simple (toothed, lobed, or dissected but not divided into leaflets) or compound (divided into leaflets). minutely serrate ..... subsp. campestris 8' Stem generally decumbent  lying mostly flat on the ground but with tips curving up. ; leaf coarsely serrate ..... subsp. obispoensis 6' Stigma generally surrounded by anthers; sepals 1.2–4(5.5) mm; petals 2–7 mm 9' Leaf generally minutely serrate ( Camissonia sierrae occasionally with only several small teeth) 10. Leaf lanceolate to narrowly ovate or elliptic, base obtuse  Having a short-tapered, blunt tip or base, the sides convex or straight and converging at more than a right angle. or rounded ..... C. sierrae 10' Leaf linear to narrowly elliptic, base acute  Having a short-tapered, sharp tip, the sides convex or straight and converging at less than a right angle. or long-tapered 12. Plant minutely strigose, or some hairs spreading and glandular, or occasionally coarsely spreading and nonglandular toward base; < 10% of pollen grains 4-angled ..... C. strigulosa 12' Plant hairs spreading, generally fine (coarse in Camissonia contorta), often glandular in inflorescence; < 10% or > 30% of pollen grains 4-angled 13' Sepals 2.5–4 mm; petals 3–5 mm 14. Leaf not (or slightly) blue-green; hypanthium  Structure generally in the shape of a tube, cup, or bowl, derived from the fused lower portions of the perianth and stamens, from which these parts seem to arise, and to which the ovary wall is fused in an inferior ovary (to which the ovary wall is partially fused in a half-inferior ovary; from which the ovary is free in a superior ovary). ± 1.2 mm; plant nonglandular hairs of 2 types (linear, white; rod-shaped, transparent); < 10% of pollen grains 4-angled; SCoRI ..... C. benitensis 14' Leaf generally blue-green; hypanthium 1.2–2.3 mm; plant nonglandular hairs of 1 type (rod-shaped, transparent); generally > 30% of pollen grains 4-angled; widespread ..... C. contorta
