(For a list of species in Eschscholzia, use the above link.) Jepson Manual glossary definitions can be seen by moving your cursor over words underlined with dots. 1. Leaves all 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. , 2–3× ternate-dissected 2. Leaves > 2× ternate-dissected; receptacle barrel-shaped; petals < 7 mm, generally falling within a few hours of flower opening, often making plant inconspicuous ..... E. rhombipetala 2' Leaves 2–3× ternate-dissected; receptacle obconic; petals >= 7 mm, not falling during first day of flower opening 3. Flower buds  1.

An unopened flower, often protected by sepals. generally nodding, held well above foliage; 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). segment tips generally rounded; seed minutely pitted; D .....
