Branches rough and brownish due the antrorse setiform trichomes. Scattered filiform and granular trichomes on stems. Stems armed with aculei usually 2–3 on nodes and eventually with some additional internodal aculei. Stipules persistent, 3.3–4.6 × 0.9–1.5 mm, oval–lanceolate, base truncated, apex acute, 4–6-nerved; glabrous on abaxial surface, pubescent filiform and antrorse setiform on upper face. Cylindrical petiole, (5.6–)10.3–26.3 × 0.6–0.9 mm; cylindrical spicule. Pinnae 1 pair; petiole 2.3–4.4 mm; paraphyllidia present. Rachilla 32.1–71.3 mm, interfoliar segments (1.2–)1.6–2.6(–2.9) mm. Leaflets (7–)10–26 jugate; blade 5.3–7.85 × 2.15–2.75 mm, elliptical–lanceolate, base oblique, apex either apiculate–acute or mucronate obtuse; 4–5-nerved immersed on upper face; filiform pubescent and adpressed setiform trichomes both on the faces. Synflorescence an apical pseudoraceme. Inflorescence capitula, prior to anthesis 5.6–7.1 × 4.3–4.9 mm, ellipsoid or globose; peduncle 16.65–20.5 mm; indumentum hispidulous. Flowers subsessile, tetramerous; calyx 0.35–1.1 mm, from campanulate with denticulate lobes to development paleaceous-like on one side; corolla 1.4–2.5 mm, with 1-nerved lobes, glabrous or with filiform trichomes on lobes; androecium composed by 4 stamens connate at base, tube 0.25 mm, whitish; gynoecium stipitate, obovate, with ciliate trichomes. Articulated craspedia 13.6–21.35 × 4.7–7.45(–8.5) mm, widely oblong, brownish; indumentum of the replum and articles dense hispidulous, soft the touch, rare hispid trichomes on margin; (1–)2–4 indehiscent articles. Seeds 4–5.2 × 3.5–3.9, ellipsoid–elliptic, brownish, pleurogram basal-apical.</p><p>Taxonomic notes —We considered that M. humidicola as belonging to the subser. Polycarpae, since the presence of interpinnal spicule, armed branches with infrastipular and infrapetiolar aculei and campanulate to asymmetrical paleaceous-like calyx. Mimosa humidicola, in contrast to M. polycarpa, can be identified by the lobes of corolla carmine standing out by the whitish stamens (opposite to yellowish corolla and lilac-pink stamens) and pods widely oblong (versus narrowly oblong or linear). The calyx of M. humidicola, contains in the same inflorescence some transitional morphologies, from denticulate lobes to paleaceous-like, suggesting affinity with morphology calyx of M. polycarpa var. subandina . Mimosa humidicola stands out by whitish filaments in mature stage of flowering, differing from sympatric species of the genus with lilac-pink filaments, such as M. adenocarpa Benth. (ser. Glandulosae (Benth.) Barneby), M. debilis Humb. &amp; Bonpl. ex Willd. (subser. Mimosa), M. polycarpa, M. pigra L. (ser. Habbasia DC.), M. somnians Humb. &amp; Bonpl. ex Willd. (ser. Bipinnatae DC.), M. weddelliana Benth. (ser. Habbasia) and M. xanthocentra Mart. (subser. Pudicae (Benth.) Barneby).</p><p>Distribution and habitat —At present, Mimosa humidicola was found in wetlands and temporary ponds in southern Mato Grosso, in the Parque Nacional do Pantanal Matogrossense, at northwest of Mato Grosso do Sul, from the Serra do Amolar to Passo do Lontra (fig. 4). The populations occur in Cambarazal formation (monodominant stands of Vochysia divergens Pohl), bays and temporary flooded open grasslands, following the course of the Paraguay River.</p><p>Phenology— Mimosa humidicola was collected in bloom in May to February and with fruits from July until February. The indehiscent articles having dense trichomes on surface, suggest that the diaspores have hydrochory as the dispersal syndrome.</p><p>Ecology— Mimosa humidicola has affinity with poorly-drained fields and bays of the rivers. This species colonizes and performs dense populations in these environments. The habitat of M. humidicola, combined with the ability to occupy new habitats and its persistence after seasonal flooding suggest a tolerance to hydric stress. In addition, the dense trichomes on pods, combined with the indehiscent articles, indicate the probable dispersal by floating for the course of rivers, streams and vazantes (leak way). During the flooding, according to our observations, this species serves as refuge for ants to nest, evidenced for the holes above the nodes. After fire events, in dry seasons, M. humidicola has capacity of regrow in grasslands, recruiting buds of underground structures. However, need more investigation about fire-ecology and adaptations for permanence in post-fire habitat.</p><p>Etymology —The specific epithet, humidicola, refers to wetlands habitat that the species grows in the Brazilian Pantanal.</p><p>Specimens examined — Brazil.

These species are common at Chaco, Cerrado, Pantanal and Seasonally Dry Tropical Forest ecorregion. In the Pantanal, the species of subser. Polycarpae are common in open grasslands.

Polycarpae) Barneby	<div><p>Distribution of subser. Polycarpae in South America</p><p>The subser. Polycarpae can be found in tropical and subtropical ecoregions in the South America, such as Andean, Cerrado, Gran Chaco, Pantanal and Seasonally Dry Tropical Forest, at 83–3000 m als. In the Bolivian Andes, the endemic species M. woodii can be found in Ceja de Monte Yungueña vegetation, between 2500 m and 2950 m als, nearly of the upper Río Cotacajes. The endemic Ecuadorian species, M. loxensis occurs in Andean slopes, on calcareous substrates, ca. 1600 m als.</p><p>Among the species, M. polycarpa is the most distributed, occurring in Argentina, Bolivia, Brazil and Paraguay. Composed of four varieties, each taxon has different distribution. Mimosa polycarpa var. polycarpa, endemic of Peru, occurs on rocky outcrops, sandy hillsides and stream-beds, above 2000 m als. Mimosa polycarpa var. redundans, endemic in Peru, occurring at Andean Marañón valley, in 2700–3000m. Mimosa polycarpa var. subandina is common in brushy hillsides and riverbanks around 600 m in Argentina and Bolivia. The most distributed variety, M. polycarpa var. spegazzinii, can be found in Argentina, Brazil and Paraguay, occurring in open fields like thickets and brushwoodlands at 83–1025 m als, being a common colonizer plant considered as a weed (Barneby 1991). In Brazil, M. polycarpa var. spegazzinii occurs in Cerrado biome, mainly in west-central region, and quite common in Brazilian Pantanal.</p><p>Regarding the distribution of the endemic species of this subseries, M. williamsii occurs in Peruvian and Bolivian intermontane valleys, as thickets at 350–450 m. Mimosa balansae is common in Paraguay and Uruguay river basins, across northern Argentina, Uruguay and southern Brazil. Regarding this, we increased the geographical distribution for M. balansae, by means the detection of specimens collected in Brazilian Humid Chaco, in Mato Grosso do Sul, around of Paraguay River Basin (Fig. 4; Appendix). Mimosa tenuipendula grows in valleys of Paraguay river, on calcareous outcrops, near 200m als. This species, according to Barneby (1991), can occur in south of Mato Grosso do Sul, but it has not been confirmed by us. Mimosa humidicola can be found in in humid vegetations of Pantanal, such as wetlands, bays and riverbanks of Paraguay river and tributaries, building large populations, in Mato Grosso and Mato Grosso do Sul, at 83–95 m als.</p></div>	https://treatment.plazi.org/id/906B8798FF9AFFD2FF3A80D2FEF2FE55	Public Domain	No known copyright restrictions apply.
