Stems cylindrical, striate, generally sparsely hispidulous to hispid, sometimes sparsely hispid to glabrous, rarely sparsely strigose, non-glandular, castaneous or green, internodes 4.4–14.8(–19.1) mm long.

Receptacle slightly convex, holopaleaceous; paleae 5.5–8.4(–9.2) × 0.8– 2.1 mm, usually longer than corolla disc, rarely equal, commonly narrowly oblanceolate, rarely narrowly oblong, apex long-acuminate, generally concave, sometimes conduplicate, light yellow.

It grows in high-elevation grasslands of the Atlantic Forest and is mostly found in open grasslands, anthropized areas, riverine vegetation, hillsides, rock outcrops, and in kaolin deposits; at elevations of 850–1360 m. <i>Calea subintegerrima</i> was found flowering and fruiting from November to April, mostly January to March with single collections in the other months.</p><p><b>Informal conservation status</b></p><p>Endangered (EN) B2ab(iii). <i>Calea subintegerrima</i> has an EOO of 13 512.842 km ² and an AOO that has increased by 4 km ² since Bueno & Heiden (2022a), now totaling 96 km ². As with other taxa from the states of Paraná and Santa Catarina, the estimated EOO includes extensive forest areas where the species does not occur, making the AOO a more accurate indicator of the species' range and threat status. Only 40% of the specimens were collected within protected areas (Área de Proteção Ambiental Campos do Quiriri, Reserva Florestal Passa Dois, Parque Estadual do Guartelá, and Parque Estadual do Monge). The populations are severely fragmented (B condition a), and due to the anthropic pressures common to grassland areas (Harfouche <i>et al.</i> 2019), there is a continuing decline inferred in habitat quality (B condition b). Thus, we propose that <i>C. subintegerrima</i> should be considered Endangered.</p><p><b>Remarks</b></p><p><i>Calea subintegerrima</i> is morphologically similar to <i>C. triantha</i>, and they are distinguished by subcordate to rounded leaf base (vs cordate); generally strigose peduncle, sometimes strigose to hispidulous (vs hispid to hispidulous), glandular-punctate peduncle (vs non-glandular), branched or slightly branched capitulescence (vs profusely branched), first series of phyllaries commonly glabrous, sometimes sparse strigose to glabrous (vs commonly hispidulous to glabrescent, rarely scabrid), second series of phyllaries generally panduriform, rarely oblong or widely oblong (vs generally oblanceolate, sometimes widely ovate or elliptic), 8–9 striate (vs 4–6).</p><p>When compared to <i>C. funkiana</i>, <i>C. subintegerrima</i> can be distinguished by hispidulous to hispid to glabrous (vs villose), generally glabrous or strigose, rarely sparsely hispidulous abaxial surface leaf (vs villose); strigose to sparsely hispidulous peduncle (vs villose), outermost series of phyllaries with apex rounded or obtuse (vs acute or attenuate), second series of phyllaries panduriform or oblong (vs widely elliptic or ovate to deltoid), third series of phyllaries 8–10 striate (vs 4–6), paleae commonly shorter 5.5–8.4 mm long (vs 9–10.5 mm); ray floret corolla frequently shorter 9.5–13.1 mm long (13–16 mm), and cypselae angles hirsute (vs densely pilose).</p> |
