Stamens usually 5-8, opposite the perianth-segments. Ovary 1-celled, free, compressed or trigenous, ovule 1. Fruit a nut, enclosed in the perianth.”

“Simultaneously with the seed of the self-pollinated F₂ plants, seed of the self-pollinated F₁ plants was again sown; the trigenous segregation was here hardly to be observed. The figures of both segregations are given in the following table.”

“Calyx much longer than the corolla, both rose-violet or rarely white; leaves 1.5-2.5 mm long, scalelike, trigenous, sagittate at base, sessile, imbricated in 4 series ... 1108. Calluna Salisb.”

“The inner surface of the seed coat is more smooth that the outer one. The wings are papery, light green and brittle when dried. The trigenous kernel is creamish coloured when young. The embryo is small and situated at one end of the cotyledons. The average weight of a single seed (ten seeds weighed separately) is 0.12g and the range of variation is 0.07 to 0.17g.”
