Table 2. Comparison of the main diagnostic characters of Bryoxiphium norvegicum and B. japonicum
Length of filiform awns in perichaetial/perigonial leaves, mm Bryoxiphium norvegicum 1–3(–5) Bryoxiphium japonicum (4–)5–12
Margin serration subentire to slightly crenulate serrate
Shape of basal leaf cells short rectangular, hardly differentiated subquadrate, ± differentiated
Length/width ratio of basal leaf cells 1.6–3.0:1 1–1.4:1
Dorsal lamella height, cell number (0–)1–3 3–4(–5)
Dorsal lamella length only in upper part of leaf descending far below, often to the leaf base
Shape of middle stem leaf apex obtuse, occasionally notched, mostly with short apiculus formed by excurrent costa and dorsal lamella or solely by costa, rarely with filiform awns to 0. 2 mm long obtuse, often notched, suddenly narrowed into filiform awn to 0. 4 mm long, formed by lamina, costa and dorsal lamella
Spore size, µm 14–19(–23) (17–)19–24
