The leaves of Leucadendron galpinii grow scattered, moderately to sparsely spaced, ascending up the often reddish stems.
The leaf is oblanceolate to linear in shape, ending in a rounded to square, even notched tip where one yellowish or red cartilaginous tooth, sometimes broad, is found. Whether the leaf has a petiole is debatable; it tapers slowly to a fairly narrow base.
The smooth, dull green to deep green or grey-green blades show faint to no signs of a midrib. The leaves sometimes twist, even in unison at a stem-tip below a cone, giving the impression of revolving (Bond and Goldblatt, 1984; iNaturalist).
