Androecial initiation is unidirectional, with a delayed initiation of the adaxial staminode, which may not arise at all in some cases (e.g., Baillon, 1860b, 1862c; Bocquillon, 1861b; Chatin, 1873a; Endress, 1998, 1999; Payer, 1857; Singh & Jain, 1978).
In Couroupita guianensis the abaxial part of the androecial ring primordium is detached as a broad flap of tissue with numerous staminodes covering the fertile stamens like a hood.
Other evidence, especially a comparison with the lateral androecial lobes of Chloranthus (Chloranthaceae), has been used for arguing a derivation of lauralean stamens from primitively branched structures (Rohwer, 1994).
