Dear Dinesh sir, There is one technical issue here. You cant write, "Hibiscus hispidissimus (syn. H. furcatus, H. aculeatus)".
Why? Because, the reprint and your link uses some words like "non Willd." and "non Walter". So it means these two names (H. furcatus & H. aculeatus) are being given by Walter and Willdenow for other taxa and they are being validly used. So your writing this way means you have merged three different species in one, which is not the case here. So now we have three names here. The above plant being: Hibiscus hispidissimus Griff., Not. Pl. Asiat. 4: 521 (1854). Synonyms: Hibiscus aculeatus Roxb., Fl. Ind. 3: 206 (1832) (non Walter 1788) (nom. illeg.) Hibiscus furcatus Roxb. ex DC., Prodr. 1: 448 (1824) (non Willdenow) (nom. illeg.) nom. illeg. means name is illegitimate according to the ICBN's Priority of Publication (Article 11), i.e., wrong, because, there are other two plants accepted with the same two names but given by two different authors. Those names are as follows: Hibiscus furcatus Willd., Enum. Pl. [Willdenow] 2: 736 (1809). Hibiscus aculeatus Walter, Fl. Carol. [Walter] 177 (1788). So the solution: If you dont wish to write the original citation like most of the taxonomists do, then, in the simplest way it can be written as: Hibiscus hispidissimus [syn. H. furcatus (not the originally described), H. aculeatus (not the originally described)]. or Hibiscus hispidissimus [syn. H. furcatus (non Willdenow), H. aculeatus (non Walter)] Hope this is understandable.
