Information
 Annual herb 5-120 cm tall or long, erect or rather scrambling; stems finely hairy with more or less appressed hairs and usually also with spreading crispate hairs. Leaves opposite or alternate, elliptic or narrowly ovate, 1.2-8 cm long, 0.3-2 cm wide, base rounded or subcordate and semi-amplexicaul, margins slightly revolute with minute teeth (difficult to see but easy to feel), apex obtuse, apiculate, green and scattered-hairy above, silvery-white tomentose beneath. Capitula rather numerous in terminal and upper axillary corymbiform cymes on long stalks; stalks of individual capitula 1-5 mm long, crispate-pubescent; involucre obconic, 2-6 mm in diameter at flowering time; phyllaries 3-seriate, narrowly ovate, 1-6 mm long, acutely pungent, green in centre, pallid and fimbriate-pectinate at the margins, often purple-tinged in centre towards apex, finely crispate-pubescent, glandular. Florets ± 9 per capitulum; corolla purple or mauve, 3-5 mm long, densely hairy (especially the lobes), lobes 1.3-2.3 mm long. Achenes obovoid, 0.8-1.5 mm long, smooth, shallowly obtusely angled but not ribbed, shortly sparsely hairy or glabrous; pappus absent. Fig. 30/1-3 (p. 127).

Notes
Lisowski treats Gutenbergia leiocarpa var. longepedicellata as a separate species, G. gracilis, which he distinguishes from G. leiocarpa on the presence/absence of hairs on the achene. This last character is variable: within the T 4 area, among similar-looking plants, the achenes vary from completely glabrous to hairy all over. Based on this variation, G. gossweileri becomes untenable as a separate species: this was distinguished only on achene indument as well. It is brought into synonymy here.
