The inflorescence consists of large colourful sepallike bracts which surround three simple waxy flowers. The involucral bracts are linear to lanceolate. The husks of walnuts develop from the bracts, bracteoles, and sepals, or sepals only. An inflorescence may include specialized stems and modified leaves known as bracts. The inflorescences are monochasic and have oppositely standing, foliage-like bracts. Below the head is an involucre of glabrous green bracts long with brownish edges. Panicles of flowers with deciduous bracts arise from new growth or the axils of leaves. Each one has a pair of bracts and four stamens. Some species produce coloured bracts at the apices. Similar terms are used for other plant parts, such as petals, tepals, and bracts. The flower heads are of yellow florets with an outer row of bracts. The umbels and umbellets usually have no upper or lower bracts. Underneath the flowers is a whorl of bracts. The flowers are in groups, supported by two large foliage-like, narrow, ciliate bracts. The bracts under the umbel soon wither.
