Fam: Asteraceae (Compositae)
Genus: Senecio L.
Species: Senecio vernalis Waldst. & Kit.
English Name: Eastern groundsel
An annual plant. Stems one or more (up to over 20), (5) 10 - 40 (70) cm high, unbranched or branched at the top; branches more or less straight; young stems and leaves are usually densely cobwebby fibrous, but in aging bare to varying degrees. Basal leaves (1) 3 - 8 cm long, 0.5 - 2.5 cm wide, oblong to elliptically lance, usually feathery-like divided, with broad, toothed rachis and toothed shares located on a petiole; middle and upper stem leaves oblong to ovate, sessile, stem-covering, with serrated ears at the base. Baskets numerous, rarely one or several, in flowering 20 - 25 mm in diameter, collected in a loose, almost thyroid inflorescence. The shell (5) 6 - 8 mm long, 4 - 6 mm wide, widely cylindrical. Inflorescence petals 5 - 15 (20), up to 1.5 - 2.5 mm long, 0.3 - 0.5 mm wide, linear to acuminate, usually with a black spot on the tip, covering the shell to about 1/4 of its length. Enveloping leaflets 18 - 22, 3 - 8 mm long, about 1 mm wide, lance, glabrous, completely green or with a black spot on top. The tongue flowers are about 5 - 9 (13), 5 - 10 (12) mm long, 2 - 3 mm wide, yellow. Fruits 2 - 3 mm long, gray-brown, more or less densely fitted fibrous between the ribs. The kite 4 - 7 mm, white.
Note. In some literature sources S. gallicus Chaix is reported for Bulgaria for the following floristic regions: Fore-Balkans (Vratsa, Veliko Tarnovo - Urum., 1901, 1935; Belogradchik - Velen, 1891), Western Stara Planina (village of Gintsi - Velen). , 1891), Sofia region (Sofia region, Kostinbrod, Dragovishtitsa, Vitosha - Velen., 1891; Urum., 1909, 1930), Znepol region (Dragoman - Velen, 1891), Thracian lowland (Chirpan - Haskovo - Urum., 1909) . Probably in most places or everywhere it is incorrectly mentioned instead of S. vernalis. It differs from the latter in the presence of 2 - 5 (6) green at the apex bracts and spaced and directed to the side, linearly elongated sections of feathery-like incised leaves. The species is distributed in Southern Europe and the Mediterranean, and is naturalized in some parts of Central Europe. Inhabits dry grassy and sandy places, uncultivated and weedy terrain. His finding in Bulgaria needs confirmation.

Senecio vernalis is one of the European species of Senecio, an annual that is also known as eastern groundsel. While it has been long classified as Senecio vernalis, this species has more recently been described as a subspecies of Senecio leucanthemifolius and is now included by some in that species.
Eastern groundsel is a "lovely yellow-flowering weed found by the roadside and on the edges of fields" that can be sometimes confused with S. eboracensis
Stems and leaves
Leaves usually wavey, dissected, with lateral lobes that are about as long as width of central undivided portion, usually conspicuously covered with fine hairs. The edges are serrated. Leaves alternate one leaf per node along the stem.
The oldest collection of seeds recorded was 16 years; average germination change for these was from 100% to 82.5%, with a mean storage period 13 years.
A Senecio and a diploid, Senecio vernalis is part of a species group along with S. flavus, S. gallicus, S. squalidus and S. glaucus who are widespread geographically and interesting for the study of genecology (the study of genetic differences in relation to the environment) and plant evolution.
