Lodiculae
The lodiculae (sing. Lodicula) or erectile tissue are small scales or scales in the flowers of most sweet grasses (Poaceae), which swell as so-called cavernous bodies when they absorb water at the time of flowering and ultimately cause the grass flowers to open . They are usually found in twos, rarely in threes (e.g. Bambusoideae ) on one side of the ovary above the cover and palea . In some species they are completely reduced (e.g. Alopecurus , Spartina ). They stand free from each other; only rarely are they fused at the edges, for example in the swaths ( glyceria ). They vary in shape and can be lanceolate, elliptical, elongated, entire or toothed. Developing genetic findings indicate that the Schwellkörperchen as a part of Perianths from inner bloom cladding are formed.
