Morphology Reproductive morphology Flowers Florets
Florets 6 – 11, hermaphrodite, showing a single spiral of florets with marginal florets at, or post, anthesis and central florets in bud (in material studied — q.v Fig. 2B); corolla tube 4 – 5 mm long × 0.6 – 1 mm diam., green, with darker veins running entire length, tube widest at base around nectaries, lower 1/3 slightly constricted, sparsely pubescent with short, uniseriate hairs, glabrous inside, corolla lobes 5, triangular, 0.5 mm long, apex acute; anther cylinder included within corolla; stamens 5, 1.9 mm long, filaments attached to corolla tube at base, anthers 2 mm long, apical anther appendages 0.2 mm long, triangular, dark pigmented, apex blunt to acute, basal appendages lacking, filament/anther collar 0.2 mm long × 0.1 mm wide same colour as pollen sacs, pollen yellow; nectary 5-lobed and fused into a ring, 0.3 – 0.5 mm long, glabrous, elliptic, base and apex dark-pigmented; style base glabrous, lacking basal node, usually darker than style shaft, style shaft to 5 mm long, glabrous, style arms 3.5 – 6 mm long × 0.2 – 0.4 mm wide, yellow with a darker line running along centre, exserted, margins entire, apex rounded to ± blunt
Morphology Reproductive morphology Fruits
Achenes rotate or spreading at maturity (q.v Fig. 2C), 4 – 11 mm long × 0.8 – 1.5 mm wide, dark green, terete, slightly wider in upper part of basal half and narrowing towards apex and base, glabrous with a few scattered short, fine tipped setulae; carpopodium narrow, slightly excentric, constricted at top, indistinguishable from base of achene; pappus knobs (3) 4 – 6, uniseriate, at first ascending in flowering florets becoming spreading after loss of corolla and in maturity, terete, 0.6 – 1.7 mm long, drying greenish-brown, ending in a globular mass of green to pale brown, shiny glands present at flower bud stage, turning to a glutiniferous, shiny-black at maturity
Morphology Reproductive morphology Inflorescences

Morphology Stem
Stems simple, erect, fleshy, green, pilose, hairs multicellular, uniseriate, eglandular, apices acute
Note
The species is named after Gracieli da Silva Henicka, one of the co-collectors of the type collection and who went back to the type locality to secure flowering material and take additional images of the flowering plants.
