Cassiope fastigiata is close relative of Cassiope fujianensis, but differs from the latter in its leaf blade 4-6 mm (vs. 2.5-4 mm), 0.5-1 mm apiculate (vs. apex obtuse, not apiculate).

Phylogeny of Cassiope was inferred from two nuclear DNA regions (nrITS and GBSS-1/waxy) and one chloroplast region (trnS-G intergenic spacer) (Gillespie and Kron, 2009). Bayesian analysis of the three DNA regions resolve nearly all relationships with strong support. One clade was resolved with five Asian species (e.g. C. myosuroides, C. nana, C. pectinata). Another clade is comprised with several Asian species (e.g. C. fastigiata, C. dendrotricha) along with Russian (C. ericoides) and northwestern North American species (C. lycopodioides). A basal grade is comprised of North American taxa (C. mertensiana and C. tetragona). Dispersal-Vicariance (DIVA) analysis suggests that the ancestral distribution of the genus may be northwestern North America and/or northeastern Asia.

Shrubs 8-20 cm tall. Stems initially decumbent, ultimately much branched, fastigiate, stiff white pubescent. Leaves densely imbricate; leaf blade ovate-triangular, 4-6 mm long, 1.5-2 mm wide, leathery, abaxially deeply furrowed, furrow reaching near apex and diverging near base, furrow rim densely pubescent, adaxially concave, subglabrous, base divergent, 2-lobed, margin silvery, membranous, densely ciliolate, apex with apicule 0.5-1 mm. Flower nutant. Pedicel 3-7 mm, densely crisped-tomentose. Calyx purple; lobes oblong-ovate, 4-5 mm, margin broadly membranous. Corolla white, broadly campanulate, 6-9 mm; lobes spreading, oblong, 2-4 mm. Stamens ca. 2.5 mm; filaments glabrous; awns ca. 1 mm. Capsule 2-3 mm in diameter.
