First of all, Lou indicated that the genus in question will be feminine. The epithet purianus would be used with a masculine genus, not a feminine genus. Purianus is an adjective and must agree with the noun it modifies (in this case, a feminine noun). Words of the form purii are genitive nouns, not adjectives, and thus do not have to agree with the noun with which they are associated. But here is something else to consider. What kind of name is Puro? If it is a name derived from a language derived from Latin, a language which keeps the distinction between the stem and the terminations which indicate case, then the form purii will work [except that Lou seems to want to observe the distinction sometimes made between the sort of honorifics which honor non-botanists (the adjectival forms) and honorifics which honor botanists (the genitive form)]. If this name Puro is regarded as an aboriginal name (or a name derived from a language itself not derived from Latin), I would suggest purona (puroiana would have been used in the past).
