- Subkingdom: Viridaeplantae
Cavalier-Smith, 1981 - Green Plants
- Phylum: Tracheophyta
Sinnott, 1935 ex Cavalier-Smith, 1998 - Vascular Plants
- Subphylum: Euphyllophytina

The Subtribe Microseridinae is further organized into finer groupings including:
- Genus (3): Agoseris · Krigia · Microseris
- Species: ZipcodeZoo has pages for 232 species, subspecies, varieties, forms, and cultivars in the Subtribe Microseridinae.
Agoseris is a small genus of liguliferous herbs in the Asteraceae or sunflower family. In general appearance they are reminiscent of dandelions and are sometimes called mountain dandelion or false dandelion. Like dandelions the plants are (mostly) stemless, the leaves being all basal and forming a rosette, contain milky sap, produce several unbranched, stem-like flower stalks (peduncles), each flower stalk bearing a single, erect flower head that contains several yellow florets, the flower head maturing into a ball-like seed head of beaked achenes, each achene with a pappus of numerous, white bristles.

Annuals or perennials, 3-75 cm; taprooted, fibrous-rooted, or (in K. dandelion) with rhizomes bearing globose tubers. Stems 1-50+, usually erect, rarely decumbent, scapiform or branched distally, glabrous or sparingly villous (proximally). glandular-villous (especially distally). Leaves mostly basal, sometimes cauline; petiolate (petioles often winged) ; blades linear to lanceolate, oblanceolate, or spatulate, margins entire, denticulate, or irregularly pinnately lobed, apices acute to obtuse (faces glabrous or glandular-villous, usually glaucous in K. dandelion and K. biflora) ; distal cauline usually slightly reduced to bractlike. Heads borne singly. Peduncles not distally inflated, ebracteate (from rosettes and from axils of cauline leaves or bracts). Calyculi 0. Involucres turbinate to campanulate, 2-12 mm diam. Phyllaries (4-) 5-18 in 1-2 series, (sometimes reflexed in fruit) linear-lanceolate to ovate, equal, herbaceous, apices acute (faces glabrous). Receptacles flat or low-convex, pitted. glabrous, epaleate. Florets 5-60; corollas yellow to orange (equaling or surpassing phyllaries). Cypselae brown or reddish brown, columnar, obconic, barrel-shaped, or fusiform, not beaked, nerves or ribs 10-20, glabrous ; pappi 0, or persistent, often fragile, usually in 2 series, distinct, outer of 5+, yellowish or brownish scales, inner of 5-45, barbellulate bristles (pappi 0 in K. cespitosa, 0 or 1 series of tiny scales in K. wrightii). x = (4) 5 (6, 9).

Microseris is a large genus of the family Asteraceae, represented on several continents. Common names include murnong, yam daisy, and silverpuffs. [more]
At least 52 species and subspecies belong to the Genus Microseris.
