Classification Section III Digitorebutia Subsection I Pygmaeae Body up to 25mm. in diameter, simple at first but becoming caespitose with age. The epidermis bluish-green often tinged deep purple particularly during the winter. Areoles elliptical with sparse greyish-brown wool, raised in the tubercles. Spines arranged in 12 distinct ribs. Centrals absent, radials strongly pectinate and adpressed, up to 12 in number, 4mm. long, greyish- white, brownish at the base. Flowers very variable, pink to salmon often bicoloured, 25mm. long and 20mm. in diameter with a white throat. Stigma 6 lobed green, style green, filaments white or pinkish. Tube brownish-green with green scales with copious white wool. Fruit dull brownish-black, dome shaped, testa finely pitted. Seed large, 7mm. in diameter, greenish-brown covered with white wool. Type locality Yavi, Jujuy Province, N. Argentina. Map 2, No. 35. Notes This species has a very wide geographical range and a large number of minor variations occur. Many of these minor variations have been described as ‘new’ species or varieties. There are for example a very large number of flower colour variants and also spine colour variants. It is indeed possible that this species could include 90% of all the species ascribed to the subsection Pygmaeae! 47
