Primula surculosa Y.Xu & G.Hao
Section Petiolares
Type specimen: Deming He Xu Xu211011 resides at IBSC (holotype).
Epithet: Named for the Latin surculus, sucker, and suffix -osa, abundant for the remarkable stolons found in this species.
Distribution: Wenshan, Yunnan.
Compared with P. taliensis in the original description, but distinctive in the indumentum in the throat of the corolla tube and the makedly stoloniferous habit. Leaves dimorphic: outer leaves spathulate to obovate-spathulate tapering to a broadly winged petiole, inner leaves: long petiolate, blade broadly ovate to suborbicular, base rounded or cordate, margin coarsely dentate. Stolons arise from the basal rosette after anthesis, terminated in a leaf rosette. Scape 1.5-3 cm, elongating to 6cm in fruit, pilose, with an umbel of 2-8 flowers on 2-3 cm pedicels, purple-rose to purple-blue, apex 3-toothed and with a tuft of white hairs in the throat. Only known from the type location on Mt. Bozhu, Bozhu Town, Wenshan City, Yunnan. The authors of this species note that stolons has multiple origins within the Genus Primula, some species being in other sections, and so the stolon may have no phylogenetic significance.
