(For a list of species in Linanthus, use the above link.) Jepson Manual glossary definitions can be seen by moving your cursor over words underlined with dots. 1. Perennial herb, subshrub; 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). lobes  1. A major expansion or bulge, such as on the margin of a leaf, sepal, or petal, or on the surface of an ovary. 2. The free tips of otherwise fused structures, such as sepals or petals; larger than teeth. sharp-tipped 2. Leaves opposite  1. Arranged in pairs along an axis - e.g., two leaves per node. 2. Occurring in the same rank, directly above or below, as 'stamens opposite petals'. 3. Located directly across from. , pinnate-3-lobed; corolla lobes 5–6; capsules  Dry fruit from compound pistil, nearly always dehiscent (irregularly or by pores, slits, or lines of separation). generally 4-valved – SnJt ..... L. jaegeri 2' Leaves generally alternate  1. Arranged singly, often spirally, along an axis - e.g., one leaf per node. 2. Occurring in different ranks, appearing to be between, not directly above or below, as 'stamens alternate petals'. , palmate- or pinnate-3–many-lobed; corolla lobes 5; capsules generally 3-valved 3.

A major expansion or bulge, such as on the margin of a leaf, sepal, or petal, or on the surface of an ovary. 2. The free tips of otherwise fused structures, such as sepals or petals; larger than teeth. 7.0–9.0 mm; corolla lobes 3.5–8 mm wide; corolla dark pink; scrub, forest, TR ..... subsp. glandulosus 6' Leaf lobes 3–5, longest lobe 4.0–6.0 mm; corolla lobes 8.0–15 mm wide; corolla pale pink; stabilized coastal dunes, s CCo, SCoRO (w edge) ..... subsp. tomentosus 1' Annual; leaf lobes not sharp-tipped 7.

Leaves alternate (opposite or ± alternate in Linanthus concinnus) 14. Leaf linear  Elongate, with nearly parallel sides; narrower than elliptic or oblong. to thread-like; corolla lobes yellow ..... L. filiformis 14' Leaf oblong  Longer than wide, with nearly parallel sides; wider than linear. , lanceolate  Narrowly elongate, widest in the basal half, often tapered to an acute tip. , or narrowly oblanceolate; corolla lobes white 15. Plant > 3 cm, stem glandular; calyx membrane not ciliate  Having generally straight, conspicuous hairs along margins or edges. ; s SNH, GB, DMoj 16. Corolla throat with 2 purple marks below lobes, tube and throat exserted  Protruding out of surrounding structure(s) (e.g., stamens exserted from corolla). from calyx ..... L. campanulatus 16' Corolla throat lacking purple marks, tube and throat included  Not protruding out of surrounding structure(s) (e.g., stamens included in corolla). in calyx ..... L. inyoensis 15' Plant < 3 cm, stem not glandular; calyx membrane ciliate; DMtns (Little San Bernardino Mtns), w DSon ..... L. maculatus 17. Corolla lobes lacking basal  At or near the base of a plant or plant part. Especially said of leaves clustered near the ground or of a placenta confined to the base of an ovary. red spot ..... subsp. emaculatus 13' Leaves opposite (or ± alternate in Linanthus concinnus) 18. Membrane ± not connecting calyx lobes; corolla tube inconspicuous 19. Stem thread-like, openly branched at base; calyx lobes with purple marks at base .....

Corolla lobes with 2 purple marks at base, 1 in each sinus  Usually pertaining to margins of leaves, sepals, petals, or other parts, an indentation between adjacent lobes or teeth ; PR, D ..... L. orcuttii 23' Corolla lobes with 1 reddish mark at base, in center of each lobe; SnBr
