✨Hệ thống APG IV

Hệ thống phân loại thực vật có hoa APG IV là phiên bản thứ tư của hệ thống phân loại thực vật hiện đại, chủ yếu dựa trên phân tử, dành cho thực vật có hoa (thực vật hạt kín) được phát triển bởi Angiosperm Phylogeny Group (APG). Hệ thống phân loại này xuất bản vào năm 2016, bảy năm sau khi hệ thống APG III tiền nhiệm được xuất bản vào năm 2009 và 18 năm sau khi hệ thống APG đầu tiên được xuất bản vào năm 1998. Phiên bản APG IV này được tham chiếu chéo với phiên bản năm 2009.

So với hệ thống APG III, hệ thống APG IV công nhận 5 bộ mới (Boraginales, Dilleniales, Icacinales, Metteniusales và Vahliales), cùng với một số họ mới, tạo nên tổng số 64 bộ thực vật hạt kín và 416 họ.
