Small garlic: The bulb is nearly spherical, 0.7-1.5 (-2) cm thick, often with small bulbs at the base (not commonly seen on specimens due to their easy shedding); the outer skin of the bulb is black, papery or membranous, does not rupture, but on specimens, only the white inner skin remains due to shedding. There are 3-5 leaves, semi-cylindrical, or triangular semi-cylindrical due to well-developed longitudinal ridges on the back, hollow, with grooves on the upper side, shorter than the flower stem. The flower stem is cylindrical, 30-70 cm tall, 1/4-1/3 covered by leaf sheaths; the bracts are 2-lobed, shorter than the inflorescence; the umbel inflorescence is hemispherical to spherical, with many densely packed flowers, sometimes with bulbils in between or all bulbils; the pedicels are nearly equal in length, 3-5 times longer than the tepals, with small bracts at the base; the bulbils are dark purple, with small bracts at the base; the flowers are pale purple or light red; the tepals are rectangular-ovate to rectangular-lanceolate, 4-5.5 mm long, 1.2-2 mm wide, with the inner whorl often narrower; the stamens are equal in length, slightly longer than the tepals up to 1/3 longer, connate and adnate to the tepals at the base, the base of the separated part widens into a narrow triangle, tapering upwards into a cone, the base of the inner whorl is about 1.5 times wider than the base of the outer whorl; the ovary is nearly spherical, with a nectariferous pit at the base of the ventral suture; the style extends beyond the tepals. The flowering and fruiting period is from May to July. Allium: Several bulbs clustered, narrowly ovoid, 1-1.5 (-2) cm thick; the outer skin of the bulb is white or reddish, membranous, does not rupture. There are 2-5 leaves, cylindrical with 3-5 ridges, hollow, nearly as long as the flower stem, 1-3 mm thick. The flower stem is lateral, cylindrical, 20-40 cm tall, covered by leaf sheaths at the base; the bracts are 2-lobed, shorter than the umbel inflorescence; the umbel inflorescence is nearly hemispherical, relatively loose; the pedicels are nearly equal in length, 1-4 times longer than the tepals, with small bracts at the base; the flowers are pale purple to dark purple; the tepals are broadly elliptic to nearly circular, bluntly rounded at the tip, 4-6 mm long, 3-4 mm wide, slightly longer in the inner whorl; the stamens are equal in length, about 1.5 times the length of the tepals, connate and adnate to the tepals only at the base, the base of the inner whorl expands, with a tooth on each side, the outer whorl is toothless, conical; the ovary is inversely ovoid, with a nectariferous pit at the base of the ventral suture; the style extends beyond the tepals.
