Morphology
Morphological comparison of the new species and known species ofSaxifraga sect. Irregulares indicates that the new species
is closely related to S.
geifolia Balf.f. and S. mengtzeana Engl. & Irmsch. The new
species
resembles S. geifolia and S. mengtzeana in leaf blade with
foliar embryo in the adaxial sinus (Figs. 1&2), which distinguish them
from other species in S. sect. Irregulares . The new
species differs from latter two species by its leaf blade abaxially
with white or virescent interveinal
streaks (vs. leaf blade abaxially with spots), involucre and bracts
conspicuous (vs. involucre obscure, bracts linear), and capsule beaks
winged when mature (vs. capsule beaks divergent) (Figs. 1&2). The
morphological comparisons are presented in Table 2.
