You can read this technical, but interesting article with this link:
http://onlinelibrary.wiley.com/doi/10.1111/j.1756-1051.2010.00974.x/pdf
Don't know if you can click on it. If not, just copy and paste.

The description of Sempervivum davisii Muirhead given by Peter J. Mitchell in The Sempervivum Society Journal Volume 5 (1974), No. 4:
"Rosette 3 to 4 cm in diameter, rosette leaves ovate to oblong-lanceolate with dense pubescence, 1.5 to 2 cm long by 1 cm broad. Flowers pale yellow. A colour plate on page 4 depicts this plant in late autumn, the rosettes are still quite small, about 1.5 cm in diameter."
