In the "scapose
inflorescence" complex, it belongs to the " leprosum subcomplex ", because their leaves neither form a rosette at anthesis (due to the early elongation of the stem and scape), nor can be distinguished from the scape bracts.
Alternatively, Tilman (1988) predicts that intense disturbances should favor small scapose
plants with high relative growth rates in nutrient-poor habitats.
Herbs perennial, scapose
or caulescent, with simple to few branched stems.
The two new species proposed here are members of the "subcomplex mello-barretoi" of the "complex with scapose
inflorescence", which was originally conceived with two species, (Leme 2004), i.
Herbs perennial, acaulescent, scapose
. Leaves rosulate; sessile to pseudopetiolate; blades entire to lyrate, lanceolate, elliptical, obovate to spathulate, pinnately veined, margin entire to runcinate, glabrous to glabrescent above, densely pubescent beneath.
