Abstract
A new species of Allium L. (Amaryllidaceae) from Zhejiang, eastern China, namely A. littoricola, was described and illustrated. Morphological analysis indicates this new species is similar to A. longistylum Baker, but differs in having ovoid bulb, tunic white, light-purple, membranous, leaf blades ascending, scape lateral, hollow in cross section or solid at base, perianth segments 5–6 × 2–3 mm, inner filaments base 1-toothed at each side; low altitude and coastal hillside habitat. Molecular phylogenetic analyses also support it as a new species and suggest that it is closely related to A. longistylum Baker.

Diagnosis: This new species is similar to A. longistylum Baker, but differs in having bulb ovoid (vs. cylindrically ovoid), tunic white, light purplish, membranous (vs. brown, papery), leave blades ascending (vs. curved), scape lateral, hollow in cross section, or solid at base (vs. central, solid in cross section), perianth segments 5‒6 × 2‒3 mm (vs. 3.5–4.5 × 1.8–2.3 mm), filament 6.4–8.2 mm long, outer ones entire, inner ones with 1-toothed on each side (vs. 8.0–9.5 mm long, margin entire or inner ones with 1-toothed on each side), below ...
Etymology: The specific epithet ‘littoricola’ refers to
the habitat of the new species.
