Androsace (Primulaceae). The book "Androsace? by G.F. Smith and D. Lowe is devoted entirely to the genus. The only specific information on seed germination is that a low T cycle is not necessary which is not entirely in accord with the present work. The genus is divided into four sections: Pseudoprimula (P) which resemble Primula, Chamaejasme (C) which are mats of rosettes spreading by runners, Aretia (Ar) which are high alpine cushions, and Andraspis (An) which are winter annuals of lower elevation. The section is indicated for each species. Most of the data was obtained before the standardization of experiments. A. sericea germ. 40(1/8)-70(518 on 2nd d) and 70(none).
Seed Germination Theory and Practice, 2nd ed., Ch. 20, Androsace p. 93. Quoted exactly. Every value on this card comes from this record, except the difficulty rating, which is ours; the step names come from a fixed list.

How each step is done, in Deno’s words, and what Verified and Derived mean.
