Felicia amoena
"Felicia amoena" is a variably hairy, sometimes glandular, biennial or perennial plant, of about high, that is assigned to the daisy family. It is somewhat woody at its base, roots at the nodes if these contact the soil, and has ascending branches. The leaves are oppositely arranged along the stems at and just above a branching fork, further up the leaves alternate. The flower heads sit individually on up to long stalks. They are in diameter and consist of about twelve to twenty five heavenly blue ray florets that surround many yellow disc florets. Three subspecies have been  recognised, that differ in width of the leaves and the involucral bracts, the size of the heads and number of ray florets and in having glandular hairs. These can be found in coastal sands and inland areas in the Western Cape and Eastern Cape provinces of South Africa. Flower heads can be found from June till October. Description. "Felicia amoena" subsp. "amoena" is an upright, up to high, biennial, possibly sometimes perennial, sometimes near its base a bit woody herb, that mostly branches copiously. The branches are often crowded near the plants foot, while the nodes that rest on the  ground easily develop roots, the more distant parts of the side branches ascend. The arrangement of the leaves on the stem changes from opposite to alternating. At the foot the leaves are in several opposite leaf pairs, and further upwards the leaves alternate, but after each branching, the lower one or two pairs are again opposite. The size of the leaves varies greatly, depending on the circumstances, and may be up to long and 2 mm (0.1 in) wide, linear to lance-shaped, bristly hairy, sometimes hairless with age, thick, with curled-down margins. The flower heads sit individually on , up to long, near the top densely felty hairy, stalks, and emerge mostly with three together at the top of the branches. The involucre is up to in diameter and consists of a double row of bracts. The involucral bracts are line- to lance-shaped, about long and adorned with a brush-like tuft of hairs at their tips. The outer bracts are wide and carry arched bristles. The inner bracts are wide, slightly bristly and have a prominent midrib. The flower heads have up to twenty five dark blue, female ray florets with straps of about long and wide . These surround many bisexual disc florets with a yellow corolla up to long. In the center of each corolla are five anthers merged into a tube, through which the style grows when the floret opens, hoovering up the pollen on its shaft. At the tip of both style branches is a triangular appendage. Surrounding the base of the corolla are many, white, serrated pappus bristles of about long. The eventually dark brown, dry, one-seeded, indehiscent fruits called cypselae are inverted egg-shaped, about long and wide, with a prominent ridge along the margin, with some scales on its surface  and short, forked hairs. "Felicia amoena" subsp. "latifolia" is a diploid having eight sets of homologue chromosomes (2n=16). Differences between the subspecies. "Felicia amoena" and its three subspecies are among the most variable taxa in the genus. Subsp. "amoena" is mostly a biennial, has linear to lance-shaped leaves of up to long and 2 mm (0.1 in) wide, with a blunt or slightly pointy tip. Its involucres are relatively large, about in diameter and bracts of about long and wide. It has up to twenty five ray florets of about 12 mm long and 2 mm wide surrounding yellow  disc florets. Subsp. "latifolia" has broader leaves, that are lance-shaped to inverted egg-shaped, 4–1 cm long and 4–10 mm wide. It also has wider involucral bracts at about 5 mm long and wide. The disc florets often turn dark red with age. Subsp. "stricta" is always a perennial with a woody base, slightly sticky because it has glandular hairs, and has small and narrow, pointy leaves of 1–1 cm long and wide, almost all of which are opposite. Its involucres are relatively small, about in diameter, with bracts only long, with only about twelve ray florets of 8  mm long and 1 mm wide. Taxonomy and naming. As far as known, the first specimen of this daisy species was collected in 1826, where the road from the Potberg crosses the Breede River, by Cape Town organ player Ludwig Beil. It is now assigned to the subspecies "latifolia". A plant collected by Johann Franz Drège at Riebeek-Kasteel, was described by Augustin Pyramus de Candolle in 1836, who called it "Agathaea stricta", is now assigned to subsp. "stricta". The first specimen now assigned to subspecies "amoena" was collected from Hout Bay on the west coast of the Cape Peninsula  by Christian Ferdinand Friedrich Krauss in 1838. It was described in 1843 by Carl Heinrich 'Bipontinus' Schultz, who named it "Agathaea amoena". In 1865, William Henry Harvey, who was a lumper, sunk "Agataea" in "Aster", creating the combination "Aster amoenus". He distinguished a slightly different specimen, that had been collected by Karl Wilhelm Ludwig Pappe, and named it after him "Aster pappei". Harvey further distinguished "Aster elongatus" var. "spathulaefolius" in the same publication. Finally Harvey regarded De Candolle's specimen as a variety that should be placed under Christian Friedrich Lessing's species "Aster adfinis" (now "Felicia dubia"), creating the  combination "Aster adfinis" var. "stricta". In 1948, the eminent South African botanist Margaret Levyns created the combination "Felicia amoena", that is still in use today. In his 1973 "Revision of the genus Felicia (Asteraceae)", Jürke Grau distinguished three subspecies: "F. amoena" subsp. "amoena", "F. amoena" subsp. "stricta", and his new taxon "F. amoena" subsp. "latifolia". The species is considered to be part of the section Neodetris. The species epithet "amoena" means "beautiful" or "pleasing" and is said to refer to the attractive flower heads. Distribution, habitat and ecology. "Felicia amoena" subsp. "amoena" has the smaller distribution of the three subspecies . It is restricted to the sandy soils around the Cape Peninsula and near Gordons Bay. Subsp. "latifolia" has the largest area and occurs along the coast from the Cape Peninsula in the very west to the mouth of the Sundays River in the east. An isolated population also occurs in the southern Cedarberg. Subsp. "stricta" can be found inland, from the Cedarberg in the north, via the Piketberg along the western edge, around Ceres, near Worcester and Swellendam on the eastern edge to Bredasdorp in the south. Conservation. The continued survival of all three subspecies of "Felicia amoena" is considered  to be of least concern because their populations are stable.
