opps... Phrag troiae if named after either the mother or daughter. Phrag
troiarum if named after both women. Phrag troianum if the adjectival case
is used. Although I still don't know why you would chose substantival vs
adjectival and there MUST be a rule guiding that decission.

Okay, so the name is Phrag Troieae not Phrag Troyae. But I've changed my
mind, and I haven't published yet, (newsgroups don't count, do they?) and
I want to name this new Phrag species after all the woman in the Troi
clan, even the less pushy ones, so it must be Phrag Troiiarum, or is it?
