    Type
    Type: Paraguay, Apepu (Tapiraguay), Hassler 4351 (holotype G).
    Habit
    Annual or briefly perennial herb to 1 m; stems somewhat woody below, herbaceous above, erect, often simple but sometimes branched, shortly puberulent with simple and basally branched hairs, although appearing glabrous without the aid of a microscope
    Leaves
    Leaves petiolate, stipules filiform with a slightly broadened base, 3 – 4 mm long; petioles 0.8 – 1.4 cm long, densely puberulent; lamina 2 – 5 × 0.3 – 0.9 cm, oblong, apex acute, base truncate to shallowly cordate, margin prominently crenate to serrate, adaxially green, minutely puberulent, abaxially greyish, densely puberulent with brown veins
    Inflorescences
    Inflorescence of solitary, pedicellate flowers arising from the leaf axils; pedicels 2 – 3.5 cm long, articulated c. 5 mm below flower, densely puberulent; calyx 5-lobed, 7 – 10 mm long, the lobes triangular, acute to shortly acuminate with a single central vein, pale green in colour, densely puberulent; petals orange, 10 – 15 mm long, clearly exceeding the calyx, glabrous, staminal column 3 mm, pubescent, filaments 1.5 mm, styles 8 – 12, 3 mm long, whitish with a purple, capitate stigma
    Fruits
    Fruit 6 – 7 mm wide, mericarps 8 – 12, laterally compressed, reticulate-veined, 3 mm long, biaristate, the aristae 2.5 mm long, both the mericarps and aristae pubescent, seeds (immature), 1.5 × 1.5 mm, subquadrangular, smooth

    Distribution
    This little-known species has only previously been recorded from isolated populations in Paraguay (Hochreutiner1905; Hassler 1910a) and Uruguay (da Monteiro Filho 1949; Krapovickas2008).
    Ecology
    In Bolivia on shallow sandy soil overlying rock at edge of cerradão associated with Evolvulus L. spp. in zone of transition from cerrado to chaco vegetation. Locally common around from 250 to 350 m approximately.
    Conservation
    This species is apparently known from three widely dispersed populations in Uruguay, Paraguay and Bolivia extending over some 1500 km distance and over ten degrees of latitude. We have no real knowledge of the size or extent of its populations in any of the three countries where it grows. As with most other Sida species it is weedy in character and has probably been overlooked despite the relatively large size of its flowers. For the time being it should be classified as Data Deficient (DD) within the IUCN (2001) classification.
    Note
    Originally described as Sidamulticrena by Hochreutiner (1905), this species was treated under the alpha variety longearistata of subspecies camporum of Sidamontana by Hassler (1910a), who a few months later raised it to specific rank as Sidacamporum (Hassler 1910b), ignoring the fact that he was creating a surplus name for a plant already described by Hochreutiner with the same type. This was pointed out by Hochreutiner (1917), who treated Sidacamporum formally as a synonym of S. multicrena. Subsequently Sidacamporum disappeared from the literature, not being cited by Krapovickas (2008) while S. multicrena also remains a little-known species (da Monteiro Filho 1949; Krapovickas2008) with no specimens cited in Tropicos or present in the Kew herbarium. It is a relatively distinct species within this complex genus because of its prominent, comparatively large, orange petals, conspicuously serrate, oblong leaves, and acute to mucronate sepals. The laterally compressed mericarps with two prominent awns are also distinctive features.
