Description
The species of ''Tecticornia'' grow as annual or perennial herbs, subshrubs or small shrubs. Stems are branched, glabrous and appear jointed. The opposite leaves are fleshy, glabrous, connate in the lower part and cup-like or collar-like stem-clasping, with minute (0–3 mm long) two-lobed to triangular leaf blades.inflorescence
An inflorescence is a group or cluster of flowers arranged on a Plant stem, stem that is composed of a main branch or a complicated arrangement of branches. Morphology (biology), Morphologically, it is the modified part of the shoot of sperma ...
s consist of opposite bracts, mostly connate and stem-clasping, free in some species. Their blades are cup- or collar-like or deltoid to semi-circular scales. In the axil of each bract, there are three to five (rarely one or seven) flowers, free or sometimes fused to each other, to the bract, and to the inflorescence axis. The flowers are hermaphrodite, rarely unisexual. They consist of a 2-3-lobed perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla ( petals) or tepals when ...
