long, sericeous adaxially, glabrous abaxially, sporangia two, sometimes the upper ones present, 
tiny and fused with the lower ones, glands 0.6 mm long, above filament base, sericeous 
adaxially, staminodes ca. 1.4 mm long, filaments sericeous adaxially, glabrous or glabrescent 
abaxially, head ca. 1 mm long triangular acuminate in outline, sericeous adaxially, mostly along 
median section, glabrous abaxially, hypanthium ca. 0.4 mm deep, glabrous ouside, pistil 2.2 - 2.4 
mm long, glabrous, ovary ca. 1.1 mm long, 0.9 - 1.2 mm wide; fruit not known. 
Flowers in August - September. Vegetation type: probably campo cerrado or campo 
rupestre. So far only known for a couple of collections in Goias, central Brazil. 
C. taubertianum is a very distinctive species and, in spite of being poorly known, is 
maintained here for the characters it presents. The whole lower surface of leaves concealed by 
hairs, coupled with the leaf shape and smooth (not conspicuous) appearance of most secondary 
and all tertiary veins, separate this species from C. sellowianum, a close morphological relative. 
Typification of C. taubertianum is not solved. Ule and Sena collections are missing, and 
to date there is only one specimen available that is annotated as collected by Glaziou (Glaziou 
20455a) near Ouro Preto, in Minas Gerais. However, a duplicate photographed at B (distributed 
as phototype) has Glaziou's number crossed out, and also a note written by Taubert saying that 
plant is a duplicate of the type then at his herbarium. The duplicate of Glaziou 20455a at P 
actually matches perfectly the original description for the species, so the name is still maintained. 
Specimens examined. BRAZIL. Minas Gerais. Gamba, near Ouro Preto, A. Glaziou 
20455a (P).
