BALLSII
Collected by E.K. Balls in 1937 and described in the Kew Bulletin 1940 page 141; details were also published in the Quart. Bull. Alp. Gard. Soc. Vol. 8 page 204 (1940). The type plant is the form collected from the Greek Epirus. Mount Tschumba Petzi, Grammos range (typus in Herb. Kew). In 1937 plants were also found in three other localities in north-west Greece. The following description is of the type form: Rosettes quite densely-leaved, about 3 cm in diameter, sub-globular, inner leaves closed with the outer leaves more open and erect, glabrous at maturity except for a few marginal cilia. The rosette-colouring is a uniform green with a bronze to red tinge on the outer leaves. The new offsets are produced on short, stout stems. The flowers are dull pink, filaments crimson. An easy species to grow but not too free in the production of rosettes.
S. ballsii from Tschumba Petzi. (described above).
S. ballsii from Skrutsch. The rosettes of this form assume a light chocolate colour in summer.
S. ballsii from Smolika. Has slightly flatter rosettes than the type with rather more ciliate hair on the rosette leaves.
