Bearing or producing cotyledons; having cotyledons as a characteristic feature.
From cotyle + -igerous (from Latin -iger meaning 'bearing' or 'producing'). The -igerous suffix appears in 'aquiferous' (water-bearing) and 'odoriferous' (odor-producing).
The -igerous suffix is delightfully specific—it means 'bearing' in the sense of 'producing and carrying,' so cotyligerous plants are ones that actively produce and carry seed leaves, a distinction botanists sometimes need to make.
