Bean cites in synonymy Santolina chamaecyparissus subsp. tomentosa Arcang., an attribution that does not find support elsewhere.
Santolina pinnata is currently applied to the taxon endemic to the Apuan Alps in western Tuscany (Giacò et al. 2022), and is no longer treated as including subsp. neapolitana (Jord. & Fourr.) Guinea ex C.Jeffrey or subsp. etrusca (Lacaita) Guinea ex C.Jeffrey, both of which are now regarded as distinct species (see the brief discussion under Santolina neapolitana). Both of these subspecies were in fact validly published in Bean (1980).
Green, glabrous leaves 1 to 11⁄2 in. long; leaf-segments 1⁄8 to 3⁄16 in. long, arranged in two or four rows. Flowers dull white. Native of Italy, flowering in July, distinguished by its white flowers and its green foliage with only a slight odour. Of little ornamental value.
