Goodenia subg. Monochila sect. Tetrathylax G.Don, Gen. hist. 3: 725. 1834 

Tetrathylax  (G.Don) de Vriese, Natuurk. Verh. Holl. Maatsch. Wetensch. Haarlem ser. 2, 10: 164. 1854 (as ' Tetraphylax  ') - Type: T. quadrilocularis  (R.Br.) Vriese ≡ Goodenia quadrilocularis  R.Br.

= Goodenia sect. Goodenia ser. Racemosae  Benth., Fl. Austral. 4: 51, 57 (1868) - Type (designated by Carolin in George (ed.), Fl. Australia 35: 331. 1992): G. decurrens  R.Br.

Description.

Subshrubs or herbs. Leaves basal or if cauline usually narrower and smaller. Flowers in thyrse-like panicles, racemes or spikes with bracteose bracts; bracteoles present. Sepals equal. Corolla bilabiate, yellow, lemon or rarely orange, hairs in throat, enations present; scarcely auriculate to auriculate. Ovary 2-locular with 15-65 ovules in two rows in each locule. Fruit a capsule, valves usually + bifid or rarely entire. Seeds 1-1.8 mm long, wing c. 0.1 mm wide and mucilaginous or with a rim.

Number of taxa and distribution.

A section of nine species present in coastal and highland areas including the Blue Mountains in eastern Australia and G. quadrilocularis  from near Cape le Grand in south-west Western Australia.

Included species.

G. bellidifolia  Sm., G. bellidifolia subsp. argentea  Carolin, G. bellidifolia Sm. subsp. bellidifolia  , G. decurrens  R.Br., G. dimorpha  Maiden & Betche, G. dimorpha var. angustifolia  Maiden & Betche, G. dimorpha Maiden & Betche var. dimorpha  , G. glomerata  Maiden & Betche, G. lineata  J.H.Willis, G. quadrilocularis  R.Br., G. racemosa  F.Muell., G. racemosa var. latifolia  Carolin, G. racemosa F.Muell. var. racemosa  , G. rostrivalvis  Domin, G. stelligera  R.Br.

Note.

Don (1834) recognised the section Tetrathylax  (meaning four - pouch) to include G. quadrilocularis  . The name was formed providing the Greek and Latin translations for tetras (four-fold) and thylax (a cell) in recognition of the 4-celled condition of the capsule. de Vriese treated the section at generic rank with the incorrect spelling ' Tetraphylax  ', which was followed by subsequent authors until corrected by Carolin (1992e).
