Leysera gnaphalodes is a perennial shrublet with radiant yellow flowers that occurs in the winter rainfall parts of South Africa and Namibia. The plant's aromatic flavours give a pleasant infusion that makes an appetizing tea.

Leysera gnaphalodes is a dwarf short-lived perennial shrub that grows up to about 1 m in height with narrow, hairy, grey to greenish leaves that are covered with stalked glands. The flower-heads are solitary on very slender stalks, and both the ray and the disc florets are bright lemon-yellow. The flowerheads have pale brown papery involucral bracts which are arranged in approximately 5 overlapping rows. The achenes (fruits, ‘seeds') are small and dry, with a feathery white pappus which probably aids in wind dispersal. Flowering time is mainly in spring, between September and November, but individual plants may be found in flower throughout the year.

Conservation status
Leysera gnaphalodes is listed as Least Concern (LC) in the Red List of South African Plants (Raimondo et al., 2009), probably due to its wide distribution range.

Distribution and habitat
This species thrives in dry areas on the sandy flats and slopes in the Namakwaland Klipkoppe, the Coastal Plain and the Knersvlakte of Namaqualand, in the Western Cape, on Eastern Cape mountains, and also in Namibia.

The genus comprises three species, of which two are endemic to southern Africa (L. gnaphalodes and L. tenella). The third species, L. leyseroides, occurs in arid parts of North Africa, southern Spain, and the Middle East).

Derivation of name and historical aspects
In October 1760 a young German botanist, Friedrich Wilhelm von Leysser, sent his new “Flora halensis” to Linnaeus (the father of modern taxonomy). Linnaeus named the genus Leysera after Leysser, who was overwhelmed by the honour and in a letter to Linnaeus, stated that he was “touched to the depths of his heart”. The name Leysera was published in 1763 in the second edition of Linnaeus' “Species plantarum” and in the sixth volume of “Amoenitates academicae” (Bremer 1978).

The name gnaphalodes means “resembling Gnaphalium ”. Gnaphalium is a genus name derived from the Greek ‘gnaphalion', which refers to a plant whose leaves are covered in fine hairs and so are used as stuffing for cushions (Trinder-Smith 2003).

In areas where this species is found in abundance, it is an indicator of disturbed veld, usually old lands. In the Namaqua National Park, the spring annual flowering display becomes less spectacular year by year as a result of disturbance, and this is reported to be mainly due to the increase in abundance of L. gnaphalodes. The species is therefore considered something of a problem plant by those who wish to cultivate showy wildflower displays in Namaqualand, as it can dominate old lands. According to a thesis done by J. K. Conradie of the University of Pretoria, Leysera gnaphalodes may colonize such areas with a relative cover exceeding 45%. This reduces the aesthetic appeal of the wildflower displays. The most effective means of control was found to be tilling or drought, as the species is resistant to induced grazing.

Uses and cultural aspects
The leaves of Leysera gnaphalodes are used to create a pleasant infusion with a blend of aromatic flavours and a sweetish taste. It is used as a tea (as suggested by the various common names) in the Cedarberg region and is also reported to be stimulating. The plant is versatile in function as it is also reported to be used as an emollient in treating catarrh (an inflammation of the throat and nose with a resultant increase in the production of mucus), coughs, as well as pulmonary tuberculosis. In some European and African regions, an infusion of the leaf and flower are used as a tonic in the loss of appetite (Watt & Breyer-Brandwijk 1962).

Both Leysera gnaphalodes and L. tenella contain a unique chemical compound known as ‘Leysseral-angelicate' (Bohlmann & Zdero 1972).

Growing Leysera gnaphalodes

There are no records of this plant being cultivated or grown. However, it should make an attractive and hardy shrub for an informal or indigenous garden where the fine, greyish foliage will provide an interesting texture contrast. Horticulturalists from Kirstenbosch National Botanical Garden advised that for optimum results, the plants should probably be grown from seed sown in early spring. Use a well-drained mixture of bark and coarse or plain river sand. Cover seed with a fine layer of sand and water well. Do not overwater but do not allow the medium to dry out completely (R. Oliver, pers. comm.).
