Gilliesieae is a tribe of herbaceous geophyte plants belonging to the subfamily Allioideae of the Amaryllis family (Amaryllidaceae). Described in 1826, it contains fifteen genera and about eighty species. It has been variously treated as a subfamily or tribe. It is native to the Southern United States, Central and South America, predominantly Chile. Of the three tribes of genera that make up the subfamily Allioideae, Gilliesieae is the largest and most variable. The tribe was divided into two tribes in 2014, Gilliesiae s.s. and Leucocoryneae, based on differences in floral symmetry and septal nectaries.
Gilliesieae are perennial herbaceous geophytes characterised by simple or prolific bulbs, sometimes with lateral rhizomes. Leaf sheaths long, tepals more or less fused and corona absent. Spathe formed from 1–2 bracts. Style more or less gynobasic. Ovary usually has two ovules per locule, side by side. There are 2–3 stamens. The commonest chromosome number is x=4. Gilliesiae is distinguished from Leucocoryneae by zygomorphic floral symmetry and the absence of septal nectaries. By contrast Leucocoryneae are zygomorphic and have septal nectaries.
