Felicia macrorrhiza is a small, evergreen shrub in the family Asteraceae. This species grows in the Karoo region of South Africa. It is called Aspoestertjie in Afrikaans. [2] [3]

Contents

It is more or less strongly branched, growing up to 15 cm (6 in) high. It has narrow leaves, crowded on the younger stems, which leave a dry, persistent leaf base on older branches. The flower heads lack ray florets but contain many yellow disc florets.

Description

Felicia macrorrhiza is an evergreen, more or less strongly branched dwarf shrub of up to 15 cm (6 in) high, with a strongly gnarled woody base. The branches are covered with gray brown bark and some long hairs. Older branches are densely set with persistent dry leaf bases, the younger ones with leaves. The leaves are alternately set, linear, sometimes spoon-shaped, more or less succulent, 1–212 cm long and 1–2 mm (0.039–0.079 in) wide, with up to 1 mm (0.039 in) wide, pale, ciliate margin, the inner base with long woolly hairs, evenly long-haired. [2]

The large flower heads are set individually on top sparingly hairy, towards the top more densely hairy, up to 5 cm (2.0 in) long stalks with some small leaves along their lengths. The involucre is about 112 cm in diameter and consists of about four rows of lance-shaped, green, overlapping bracts, often with the margin tinged reddish, hardly papery and ciliate towards the tip. The outer involucral bracts are about 5 mm (15 in) long and 1 mm (0.039 in) wide with long hairs, the inner bracts 14 mm (0.55 in) long and 112 mm wide with fewer long hairs. The flower heads never have ray florets. There are many disc florets with a yellow corolla of up to 8 mm (13 in) long, in the center of each of these 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. Around the base of the corolla are many yellowish white pappus bristles of two different lengths. The longer pappus bristles are about 9 mm (0.35 in) long, toothed, with a long pointy tip. The shorter pappus bristles are up to 112 mm long. Below the base of each corolla is a red-brown, dry, one-seeded, indehiscent fruit called cypsela that is about 5 mm (15 in) long and 2 mm (0.079 in) wide, inverted egg-shape in outline, with a slight ridge along the edge. The surface has few scales and long silky hairs, often with a narrow hairless zone bordering the edge. [2]

Heads without ray florets also occur from time to time in related species of the section Lignofelicia, in particular F. whitehillensis, F. filifolia subsp. bodkinii and subsp. schaeferi. [2]

Taxonomy

This species of daisy was first described in 1800 by Carl Thunberg, who named it Aster macrorrhizus. In 1836, Augustin Pyramus de Candolle assigned Thunberg's type to the genus Felicia, so creating Felicia macrorrhiza. He also described another collection in the same publication, which he called Fresenia scaposa. When Ernst Gottlieb von Steudel accepted De Candole’s name, a printing error was made, and the name Fresenia stuposa was published in 1840. In 1917, John Hutchinson distinguished Fresenia nana. In 1973, Jürke Grau considered all these names synonymous to Felicia macrorrhiza. The species is considered part of the section Lignofelicia . [2]

Conservation

The continued survival of Felicia macrorrhiza is considered to be of least concern because its population is stable. [3]

Most of the narrowly inverted egg-shaped leaves are silky hairy and in a basal rosette with no or few very narrow bracts on the stalk in the subspecies bellidioides. In the subspecies foliosa, the narrower leaves are not silky hairy but variously bristly and glandular, with more and larger bracts on the inflorescence stalk. The flowerheads sit individually on top of a long peduncle and consist of an involucre with only two worls of bracts, about twenty purplish blue ray florets, surrounding many yellow disc florets. It occurs in the Western Cape province of South Africa.

No fertile seeds have been found, so this species may solely reproduce vegetatively. The species is only known from one location in the KwaZulu-Natal Drakensberg, where it grows on damp stream banks.

It has alternately arranged leaves, and flower heads with 3–4 whorls of involucral bracts with many yellow disc florets in the centre. Very characteristic for the species are the short club-shaped hairs on its fruits. There are two subspecies. Subsp. clavipilosa has narrowly lance-shaped entire leaves with one vein and pale mauve ray florets. Subspecies transvaalensis has lance-shaped leaves with one or three veins and white ray florets. The species occurs in southern Africa, with subsp. clavipilosa having a western distribution in Zambia, Zimbabwe, Namibia, Botswana and South Africa, and subsp. transvaalensis restricted to the east, from Zimbabwe, through Botswana to South Africa. The subspecies transvaalensis is sometimes called pokkiesblom in Afrikaans.

Very characteristic for the species are also the middle-long hairs with forked tips on the surface of its fruits. It is an endemic species that is restricted to a zone along the southern coast of the Western Cape province of South Africa.

Felicia smaragdina is an annual, bristly and glandular, much branched plant of up to 40 cm high, that has been assigned to the family Asteraceae. It has seated, slightly succulent, line-shaped leaves of up to 3 cm long and about 1 mm (0.04 in) wide. Its flower heads sit individually at the tip of the branches, and contain about twenty yellow ray florets of about 8 mm long and 112 mm (0.06 in) wide, surrounding many yellow disc florets. A unique character is that when dried, the florets become greenish. The species is an endemic species of Namibia.

Felicia tenella is an annual, sometimes biennial, herbaceous plant that may be slightly woody at its base, of 5–70 cm tall, that is assigned to the family Asteraceae. The species is very variable in size and hairiness. Its branches may be erect or ascending, and the leaves are narrowly line-shaped, 2–5 cm long and about 1 mm (0.04 in) wide. The leaves have a callous tip, lack visible nerves, and are mostly rigidly ciliate. The flower heads sit individually at the tip of stalks, have an involucre of three whorls of bracts, and about thirty light blue ray florets surrounding many yellow disc florets. Four subspecies are recognised. The species naturally occurs in the Northern Cape and Western Cape provinces of South Africa.
