Abstract. Zygotes released from female receptacles can be recruited in large quantities unto artificial substrates and within 24 h produce multicellular embryos characterized by multiple bundles of rhizoids, and after 48–72 h elongated into germlings.

In light of our findings, we propose to consider several new synonymies for S. aquifolium, S. ilicifolium, S. polycystum, and S. polyphyllum. S. baccularia was clearly separated out from S. polycystum and S. stolonifolium using primer OPA13. p 23–41. Actual farming of seaweeds in the Philippines is limited only to three commercial species, e.g., Eucheuma alvarezii (commercially known as the "cottonii type"), E. denticulatum (the "spinosum type") and Caulerpa lentil-lifera.
