The ones to look out for are plants that are hairy (they are hairy for a reason), those that have resinous saps (has toxic oils), white saps (sure indication of plant alkaloids and phytotoxin), overpouring/overflowing clear saps (not indicative of poison but may contain trace elements or amino acids that are harmful or unnecessary for animal growth or else hinder it) and plants with bitter/tangy/spicy/pungent smelling & tasting saps with the exception of bulbous plants that have a rooty/earthy/aromatic/sweet smell (i.e. most members of the lily family) that are toxic if ingested.

Of course the toughness of the plant in question is also a factor as some frogs are normally found near or among toxic plants in the wild but if that plant is tough or sturdy enough then the chances of it breaking a leaf/stem and ooze out saps is virtually low
