Leaves

The leaves of Taraxacum ceratophorum are primarily basal, with a patent or erect orientation. They are alternate in arrangement and die annually. Petioles may or may not be present, ranging from 0 to 40 (or occasionally up to 70) mm in length. These petioles can be winged, either broadly or narrowly, and are typically glabrous. The leaf blades of this species are simple in structure, with attenuate bases. They measure 50 to 120 mm in length and 7 to 30 mm in width, displaying an oblanceolate shape. The blades are flat and appear to have a single vein or pinnate veins. The adaxial surface of the blade is glabrous, as is the abaxial surface. The blades can be broadly or narrowly lobed, with runcinate and dentate margins. The degree of incision can range from 5% to 95%, and the apices of the lobes are acute. The blade margins may exhibit between 1 and 8 (or occasionally up to 11) teeth on each side, counting both the dentations and tips of the runcinate lobes. These teeth are located toward the apex of the blade.^[3]

Flower

Taraxacum ceratophorum bears flowers on stems that lack leaves. The flowering stems are hairy, with simple hairs that are longer than the diameter of the stem. These hairs are white or translucent and become floccose near the inflorescence. The flowers are arranged in solitary heads, which are approximately 15 to 30 mm deep when viewed from the side and 30 to 40 mm wide. Only ligulate florets are present in the heads, and there are no pedicels. Involucral bracts are present, with 2 to 3 rows. The outer involucral bracts are predominantly dark green, lying adjacent to the flowers. They are ovate or lanceolate, tapering toward a narrow apex and measuring 5.5 to 11 mm in height and 1 to 3.5 mm in width (noticeably longer than wide and proportionately narrow). These bracts are glabrous. The inner involucral bracts are lanceolate, ranging from 12 to 20 mm in height and 2.5 to 3 mm in width. Their margins are narrow and scarious, occupying less than one-quarter of the bract, and their apices are prominently horned or callosed.^[3]

Each inflorescence of Taraxacum ceratophorum typically contains 40 to 60 bilaterally symmetrical (zygomorphic) flowers. The sepals are represented by a pappus, which consists of a single row of whitish hairs. The ligulate florets possess a pappus that measures 6 to 8 mm in length. The petals of the species are conventional, fused, and yellow, sometimes exhibiting a cream color when pressed, and with a greyish stripe in the outer petals. Fresh flowers may lack contrasting markings, but these markings may appear as greyish tinges upon drying. The corolla is flat and strap-like, and the limb of the ray florets is 1.5 to 2.5 mm wide. The limb of the ligulate florets measures 40 to 60 mm in length and 10 to 14 mm in width. Taraxacum ceratophorum has five stamens with yellow anthers measuring 2.8 to 4.2 mm in length. The ovary is inferior, comprising two syncarpous carpels. It features a single style that is 7 to 8 mm long (noticeably shorter than the petals). Each ovary has two stigmas, and the placentation is basal. There is one ovule per ovary.^[3]

Fruit and seeds

The fruit of Taraxacum ceratophorum are sessile cypselas with a persisting calyx. They are dry, obovate, and typically a pale reddish brown or brick red colour. The cypselas measure 4 to 5 mm in length and 0.9 to 1.2 mm in width, appearing glabrous and exhibiting ribbed surface venation. They are indehiscent, and the slender beak of the cypselas often exceeds the length of the body. The upper half of the cypselas' surface is spinulose. Each cypselae possesses a single seed.^[3] The seeds utilize wind dispersal. The pappus of each seed helps amplify drag, which increases the chance that wind will carry it away and prolongs its descent.^[4]

Roots

Taraxacum ceratophorum possesses a taproot. The taproot is robust, supporting the growth and stability of the plant. Additionally, the species exhibits a caudex with a diameter of approximately 5 to 10 mm. The caudex serves as a transition zone between the taproot and the basal leaves.^[3]
