Common Name: SUNFLOWER FAMILY Habit: Annual to tree. Leaf: basal and/or cauline, alternate, opposite, rarely whorled, simple to 2+ × compound. Inflorescence: 1° inflorescence a head, resembling a flower, of several types (see below), 1--many in generally +- cyme-like cluster; each head generally with +- calyx-like involucre of 1--many series of phyllaries (involucre bracts); receptacle of head flat to conic or columnar, paleate (bearing paleae = receptacle bracts) or epaleate; flowers 1--many per head. Flower: bisexual, unisexual, or sterile, +- small, of several types (see below); calyx 0 or modified into +- persistent pappus of bristles, scales, and/or awns; corolla radial or bilateral (0), lobes generally (0)3--5; stamens 4--5, filaments generally free, generally fused to corolla at tube/throat junction, anthers generally fused into cylinder around style, anther base generally rounded or cordate (deeply sagittate or with tail-like appendages), tip (= flattened appendage) generally projecting beyond pollen sac; pistil 1, 2-carpeled, ovary inferior, 1-chambered, 1-seeded, placenta basal, style 1, tip generally +- 2-branched (except in some staminate disk flowers), branch tips truncate or generally bearing +- brush-like appendages; stigmas 2, generally on adaxial faces of style branches. Fruit: achene (also called a cypsela) (drupe in Chrysanthemoides), cylindric to ovoid, sometimes compressed, generally deciduous with pappus attached. Genera In Family: +- 1500 genera, 23000 species: worldwide, many habitats. Note: Flower and head types differ in form and sexual condition. A disk flower has a generally radial corolla, with a cylindric tube, expanded throat, and generally 5 lobes. Disk flowers are generally bisexual and fertile but occasionally staminate with reduced ovaries. Discoid heads comprise only disk flowers. A radiant head is a variant of a discoid head, with peripheral disk flower corollas expanded, often bilateral. A ray flower corolla is bilateral, generally with a slender tube and flattened petal-like ray (single lip composed of generally 3 lobes). Ray flowers are generally pistillate or sterile (occasionally lacking styles). Radiate heads have peripheral ray flowers and central disk flowers. Disciform heads superficially resemble discoid heads, with pistillate or sterile flowers that lack rays, together with or separate from disk flowers. A ligulate flower is bisexual, with a bilateral, generally ephemeral corolla and 5-lobed ligule. Liguliflorous heads comprise only ligulate flowers.

Common Name: MUGWORT, SAGEBRUSH, SAGEWORT Habit: Annual to shrub, generally aromatic. Leaf: entire to +- lobed, glabrous to densely hairy; hairs glandular (resin-filled) or T-shaped, hollow. Inflorescence: heads discoid or disciform, in spike-, raceme-, or generally panicle-like clusters; involucre ovoid to hemispheric, generally concealing flowers; phyllaries in 1--several series, persistent, margins scarious; receptacle hemispheric to conic, generally epaleate, generally glabrous. Pistillate Flower: 0--many; corolla generally <= 2 mm, tubular, rarely short ray-like extension present. Disk Flower: 3--many, generally bisexual, sometimes staminate (ovary vestigial, style branches remaining erect or style unbranched, tip expanded, tack-shaped); corolla <= 2.5 mm, +- pale yellow, tube < throat, lobes short-triangular; anther tip acute-ovate to awl-shaped; style tips flat, truncate, hair-fringed. Fruit: < 2 mm, obovoid or fusiform, sometimes ribbed, glabrous, hairy, or resin-gland-dotted; pappus generally 0 or minute crown. Etymology: (Greek: Artemis, goddess of the hunt, noted herbalist, Queen of Anatolia) Note: Reports of Artemisia campestris L. subsp. pacifica (Nutt.) H.M. Hall & Clem. for California unconfirmed. Artemisia arbuscula var. thermopola Beetle not in California. Artemisia absinthium L. often cultivated, may persist, perhaps naturalizing in northeastern California. Recent studies place Sphaeromeria in the Artemisia clade (Garcia et al. 2011 Amer J Bot). eFlora Treatment Author: Leila M.

2. County and Jepson Region polygons can be turned off and on using the check boxes.
(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
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.
