The mature embryos of Cuscuta japonica, C. australis and C. chinensis are of structures of yellow cylinder, tapering toward the apex and spirally coiled. They bear a few plumular scales but no cotyledon. Lacking in the opposite leaves, the phyllotaxis of seedlings is distichous from the first and it gradually changes to spiral. Such a phyllotaxis should be called “Cuscuta-type”.
