Y-shaped hair on adaxial surface of E. alsinoides from Khon Kaen (d). Y-shaped hair and capitate gland of E. glomeratus (e), capitate gland on leaf surface of E. nummularius (f). Sinuous or straight to curved anticlinal walls on abaxial epidermal layer of E. alsinoides (g), E. glomeratus (h) and E. nummularius (i).
