Lee, Sang-Rae & Lee, Eun-Young, 2018, Desmarestia japonica subsp. angustifolia (Desmarestiales, Phaeophyceae), a new subspecies from Korea, Phytotaxa 365 (1), pp. 89-95 : 94

Desmarestia japonica subsp. japonica

The thallus is light olive brown in color and becomes greenish brown when exposed to air. The Korean specimens are up to 67 cm in height and have mostly three orders of branching. The main primary blades were 3.5 mm wide, although they were up to 4 mm wide in tall specimens. The secondary blades had a maximum length of 7–25 cm and maximum width of 0.3–2.9 mm. The gross morphology, with feather-like pinnate branching, was similar to that of Japanese ligulate Desmarestia species.
