Baccharis linearis, the romerillo or Chilean little rosemary, is a common shrub in Central Chile. It is frequently found in old field after agriculture. Cecidia or galls caused by the fruit fly Rachiptera limbata grow as white, spongy and globose tissues on the twigs of the plant. [2] [3]

Description

This densely branched, shrubby species reaches heights of 1–3 m. The branches are erect. Young branches have a green bark, which becomes reddish brown with age. The linear, sessile, rarely dentate leaves are 0–30 mm long and 0-2.5 mm wide. Dentate leaves are observed on young plants, but this characteristic is lost in later ontogenic stages, in which only linear leaves devoid of any dentation are formed. The capitula are formed in groups. In male plants they are 3-4.5 mm wide and in female plants they are 2–3 mm wide. They are attached to the branches by 3–8 mm long peduncles. [4]

Natural hybridisation

This species is part of a homoploid hybrid swarm involving Baccharis macraei . Together both parent species form the natural hybrid Baccharis intermedia . [5]

<i>Chilopsis</i> Genus of plant with a single species

Chilopsis is a monotypic genus of flowering plants containing the single species Chilopsis linearis. It is known commonly as desert willow or desert-willow because of its willow-like leaves, but it is not a true willow – being instead a member of the catalpa family.

<i>Baccharis</i> Genus of flowering plants

Baccharis is a genus of perennials and shrubs in the aster family (Asteraceae). They are commonly known as baccharises but sometimes referred to as "brooms", because many members have small thin leaves resembling the true brooms. They are not at all related to these however, but belong to an entirely different lineage of eudicots. B. halimifolia is commonly known as "groundsel bush", however true groundsels are found in the genus Senecio.

<i>Fuchsia magellanica</i> Species of flowering plant

Fuchsia magellanica – commonly known as the hummingbird fuchsia, hardy fuchsia or chilco – is a species of flowering plant in the evening primrose family Onagraceae, native to the lower Southern Cone of southern South America.

<i>Drosera anglica</i> Species of carnivorous flowering plant in the family Droseraceae

Drosera anglica, commonly known as the English sundew or great sundew, is a carnivorous flowering plant species belonging to the sundew family Droseraceae. It is a temperate species with a circumboreal range, although it does occur as far south as Japan, southern Europe, and the island of Kauai in Hawaii, where it grows as a tropical sundew. It is thought to originate from an amphidiploid hybrid of D. rotundifolia and D. linearis, meaning that a sterile hybrid between these two species doubled its chromosomes to produce fertile progeny which stabilized into the current D. anglica.

<i>Persoonia linearis</i> Shrub in the family Proteaceae native to New South Wales and Victoria in eastern Australia

Persoonia linearis, commonly known as the narrow-leaved geebung, is a shrub native to New South Wales and Victoria in eastern Australia. It reaches 3 m (9.8 ft), or occasionally 5 m (16 ft), in height and has thick, dark grey papery bark. The leaves are, as the species name suggests, more or less linear in shape, and are up to 9 cm (3.5 in) long, and 0.1 to 0.7 cm wide. The small yellow flowers appear in summer, autumn and early winter, followed by small green fleshy fruit known as drupes. Within the genus Persoonia, it is a member of the Lanceolata group of 58 closely related species. P. linearis interbreeds with several other species where they grow together.

<i>Dicranopteris linearis</i> Species of plant

Dicranopteris linearis is a common species of fern known by many common names, including Old World forked fern, uluhe (Hawaiian), and dilim (Filipino). It is one of the most widely distributed ferns of the wet Old World tropics and adjacent regions, including Polynesia and the Pacific. In parts of the New World tropics its niche is filled by its relative, Dicranopteris pectinatus.

<i>Dudleya attenuata</i> Species of succulent

Dudleya attenuata is a species of perennial succulent plant known by the common name taper-tip liveforever, native to Baja California and a small portion of California. A rosette-forming leaf succulent, it has narrow pencil shaped leaves that can often be found covered in a white epicuticular wax. The thin, sprawling stems branch to form the clusters of rosettes, with plants creating a "clump" up to 40 cm wide. The small flowers are white or yellow, with 5 spreading petals. It is a diverse, variable species that extends from the southernmost coast of San Diego County to an area slightly north of the Vizcaino Desert, hybridizing with many other species of Dudleya in its range. Some plants with white or pinkish flowers were referred to as Orcutt's liveforever, referring to a former subspecies split on the basis of the flower color.
