TABLE 1. Detailed comparison of Allium sikkimense, A. kansuense and A. brevipedicellatum.

Morphological characters	A. sikkimense	A. kansuense	A. brevipedicellatum
...continued on the next page
Bulb coat	The outer layer dark brown, splitting into fibrous strands, becoming nearly reticulate (net-like) at the base, occasionally breaking into linear fragments.	The outer layer later develops into a finely reticulated fibrous texture.	The outer layer is yellowish-brown, breaking into fibrous strands.
Leaf	Flattened, shorter than the scape, 2–5 mm wide.	Gradually tapering to a flattened linear apex, 2–5 mm wide.	Narrowly linear, flat, and 1 mm wide.
Scape	Cylindrical, with a drooping apex.	Cylindrical, with a distinctly nodding apex.	Cylindrical, erect.
Inflorescence	The umbel is hemispherical, with numerous densely clustered flowers, typically exceeding 10 in number.	The umbel is hemispherical, often multi-flowered.	The umbel is hemispherical, bearing 5–15 flowers (rarely more).
Pedicel	Nearly equal in length, 6–10 mm long,	Subequal in length and shorter than 8–9 mm long.	Subequal in length, very short, measuring 1–2 mm long.
Flower color	Sky blue	Vivid blue	Purplish-red
Tepal	6–10 mm long, 3–4.5 mm wide; ovate or ovate-oblong; apex obtuse; inner tepals usually slightly longer and wider than the outer ones.	8–9 mm long; oblong-elliptic; apex obtuse; outer tepals slightly shorter than the inner ones.	4–6 mm long, 2–4 mm wide; outer tepals oblong with acuminate apex, inner tepals longer than the outer ones, oblong-ovate with obtuse apex.
Filament	About half to two-thirds the length of the tepals; equal in length; blue; shorter than the pistil.	The outer whorl filaments have a basal width twice that of the inner whorl; dilated at the base and abruptly contracted into a filiform form; blue.	Slightly shorter than the tepals; subequal in length; the inner whorl filaments are expanded into an ovate form at the base; white; nearly equal to the pistil in length.
