Inner tepals erect, lanceolate-muticous, without a terminal spiny arista.. Outer tepals deeply perforated with usually 6 small pits, in 2 longitudinal rows, above the rim.. Spines 1.5–2 mm. long, somewhat arcuately curved at the base and remaining a little reflexed or becoming horizontal.. Fig. 1/3, p. 2.
