Bot. 1885: 217 . 1885 . Range: — Bolivia (SC) and Brazil . Ecology: —Rare (known from a single collection); open vegetation in lowland regions, on sandy soils of rocky areas; 400 m . Notes: —Rachises slightly flexuous, glabrous; plants ca. 5–7 cm tall, with pinnae 2–4 × 1–3 mm , articulate, rhombic or cuneate, stalked, stalks very thin (hairlike), less than 1 mm long, with the color of stalks stopping abruptly at pinna bases; pinnae glabrous on both surfaces and idioblasts lacking, terminal pinnae similar to lateral ones, sterile margins slightly lobate or cleft; sori 1 or 2 per pinna, borne distally; and indusia rounded, glabrous. This species has historically been treated as an Adiantum , but recent phylogenetic data show it is more properly placed in Adiantopsis ( Schuettpelz et al . 2014 ) . In Adiantum , the sporangia are borne on the underside of the indusia, whereas in Adiantopsis senae , the sporangia are attached at the indusial bases.
