Fig. 1 in A taxonomic revision of the Othonna coronopifolia L. group (Asteraceae: Senecioneae: Othonninae)
Fig. 1. General morphology of the O. coronopifolia group. A. Habit of O. coronopifolia showing obovate to oblanceolate leaves and capitula with 7 or 8 ray florets; B. Habit of O. leptodactyla showing the linear or narrowly lanceolate leaves and capitula with 7 or 8 ray florets; C1-C2. Habit of O. pteronioides showing the small oblanceolate to elliptic leaves in axillary tufts, the divaricate branches ending in thorns and capitula on short-shoots; D. Habit of O. ramulosa showing the leaves fasciculate on short-shoots and capitula with 7 or 8 ray florets; E. Habit of O. spinescens showing the woody spinescent peduncles, the fasciculate leaves on short-shoots and an involucre with 7 or 8 ray florets; F1-F2 Habit of O. pavonia showing the pinnatisect leaves, the deep red or maroon stems, solitary inflorescence and capitula with 5 ray florets.

Fig. 2 in A taxonomic revision of the Othonna coronopifolia L. group (Asteraceae: Senecioneae: Othonninae)
Fig. 2. Vegetative variability in species of the O. coronopifolia group (A1-A3, O. coronopifolia) (A1) showing dwarf plants growing along the coast, obovate-oblong, cuspidatemucronate leaves; (A2) plants with capitula on short-shoots, the peduncle mostly 50̅150 mm long; (A3) larger plants mostly with leaves often irregularly toothed or sometimes 3- pinnatifid, often in axillary tufts and on short-shoots; (B1-B2, O. leptodactyla) showing the linear or narrowly lanceolate leaves with linear lobes; (C1-C2, O. ramulosa) (C1) showing leaves mostly fasciculate on short-shoots, oblanceolate, inflorescence terminal on stem, old peduncles ending in thorns; (C2) leaves elliptic, narrow below and petiole-like, inflorescence on short-shoots along stem; (D1-D2, O. pteronioides) showing the divaricately branched habit, tips developing into thorns, the small oblanceolate-elliptic leaves, inflorescence terminal on stems or on short-shoots; (E1-E3, O. spinecens) showing an inflorescence that is either terminal on stems and then a divaricately branched corymb the peduncles becoming woody and spinescent after flowering, or solitary sub-erect capitula terminal on short-shoots and narrowly oblanceolate leaves; (F, O. pavonia) showing the pinnatisect leaves, an inflorescence of few to several capitula in lax corymbs and deep red to maroon stems when young and 5 ray florets and involucral bracts.
