4624F0A8AB9E5DFAB952DDDAFD0DDBDB.taxon	diagnosis	Diagnosis. D. paposanum is distinctive from most species of the genus because of its lack of tomentose or lanate hairs on its vegetative parts, including the adaxial side of the leaves. Additionally, D. paposanum has glandular succulent leaves, and short branches with leaves that are glabrate or scarcely puberulous in the apical section of long shoots.	en	Ibanez, Sergio T., Munoz-Schick, Melica, Scherson, Rosa A., Moreira-Munoz, Andres (2022): A new species of Diplostephium (Asteraceae, Astereae) from the Atacama Desert, Chile.

4624F0A8AB9E5DFAB952DDDAFD0DDBDB.taxon	description	Description. Shrub up to 70 cm tall, subglobose, resinous, generally glabrate but puberulous with hairs mixed with stipitated glands in younger twigs, with ramified erect, indeterminate, ascending, long branches, and shorter, rarely ramified, ascending lateral branches of up to 10 cm borning mostly near the apex of long branches, base of long branches naked, covered with leaves scars. Leaves alternate or fasciculate, densely covering the upper part of the branches and decreasing downward, (1 -) 2 - 5 (- 8) x 0.3 - 0.8 mm, succulent, lamina strongly revolute, hence clavate to terete, sessile, covered with sunken glands, younger leaves in plantlets laminar, linear-oblong, with 1 - 2 teeth at each side of the lamina. Capitula solitary or rarely in pairs, terminal in short lateral branches, heterogamous, radiate. Peduncles (1.5 -) 2.8 - 3.9 (- 5.5) mm long, often with peduncular bracts 1.0 - 2.3 x 0.3 - 0.8 mm, similar to leaves but subulate and base swollen. Involucre 4.1 - 6.1 x 3.0 - 4.5 mm, cylindrical; phyllaries arranged in 3 - 4 series, acute to obtuse, margin hyaline, central rib visible on both sides; outer phyllaries 1.3 - 2.6 x 0.5 - 0.8 mm, subulate to deltoid; middle phyllaries 2.4 - 3.8 x 0.6 - 0.9 mm, subulate to lanceolate, with or without distal purple spot; inner phyllaries 3.7 - 4.2 x 0.8 - 1 mm wide, linear-lanceolate with a distal purple spot; receptacle 1.0 - 1.5 mm diameter, convex, alveolate, epaleate. Ray florets 7 - 10, pistillate; corolla white, tube 2.3 - 4.2 x 0.3 - 0.4 mm, limb 4.2 - 7.1 mm x 1.6 - 2.2 mm, elliptic, minutely 3 - lobed; style glabrous, 2.8 - 4.4 x 0.1 - 0.2 mm, linear, style branches 0.8 - 1.7 x 0.1 - 0.2 mm, linear, flat, with a purple marked line on the middle. Pappus composed of 17 - 36 bristles of two lengths, short bristles 1.2 - 2.1 mm, long bristles 3 - 7.3 mm, scabrid becoming barbellate towards apex. Cypselae of ray florets 1.4 - 2.9 x 0.4 - 0.8 mm, shape as in disk florets; carpopodium 1.4 - 1.9 x 0.4 - 0.8 mm. Disk florets 10 - 20, bisexual; corolla yellow, tube 4.3 - 6.0 x (0.5 -) 1.0 - 1.2 mm, narrowly infundibuliform, linear at the base, limb of 5 lobules, each 0.6 - 1.1 x 0.3 - 0.6 mm, deltoid; anthers 2.4 - 3.5 x 0.2 - 0.3 mm, ecaudate, cuneate, apical appendage deltoid, filaments 1.2 - 1.8 x 0.05 - 0.1 mm; style 6.3 - 7.1 x 0.2 mm, linear, style branches 1.7 - 2.3 x 0.2 mm, lanceolate, apex acute, distal end straight. Pappus as in disk florets. Cypselae of disk florets 1.7 - 3.4 x 0.4 - 0.8 mm, fusiform, slightly compressed, ribbed, villous; carpopodium present, 0.1 x 0.2 mm.	en	Ibanez, Sergio T., Munoz-Schick, Melica, Scherson, Rosa A., Moreira-Munoz, Andres (2022): A new species of Diplostephium (Asteraceae, Astereae) from the Atacama Desert, Chile.
