Daftar ahli botani berdasarkan singkatan penulis

Berikut ini adalah daftar botanis berdasarkan singkatan penulis, yang didesain sebagai kutipan nama botanis atau karya yang telah mereka terbitkan. Daftar ini mengikuti daftar yang dibuat oleh Brummit & Powell (1992). Penggunaan daftar ini direkomendasikan oleh Rec. 46A Note 1 dalam International Code of Botanical Nomenclature. Daftar yang paling baru dapat dilihat di The International Plant Names Index dan Index Fungorum.

Catat bahwa dalam beberapa kasus, "singkatan penulis" terdiri atas marga penuh, sedangkan dalam hal ini, marganya disingkat dan/atau disertai dengan 1 inisial atau lebih. Tidak ada ruang antara inisial dan marga (atau singkatannya).

Daftar ini dipelihara secara ketat secara alfabetis dalam singkatan; sehingga "A.B.Jacks." muncul di bawah "A", bukannya "J", dan dicari seolah-olah karakternya adalah "ABJACKS". Kapitalisasi diabaikan dan semua karakter non-alfabet seperti "." dan spasi. Tanda diakritik juga diabaikan, jadi "ü" diperlakukan sama seperti "u".
