This species is the smallest terrestrial aroid in the Mediterranean, growing only to 8 cm tall.

It is usually found growing in woodlands on north faces of hillsides and in humus soil that is covering limestone.

It is distributed in Sardinia, Corsica, Sicily, southern mainland Italy, Tunisia, and Algeria.

[6] However, seeds are rarely formed, as this species exhibits a low reproductive rate.

Ambrosina is the sister group to Arisarum, from which it separated about 46.1 Million years ago.

[3] Multiple species have been moved from the genus Ambrosina to Cryptocoryne: The inflorescences are visited by springtails, Embiidae, earwigs, mites of the genera Penthaleus or Bdella, and millipedes.

[7][6] Ambrosina foliage may be affected by reddish-brown, 0–1 mm large leaf spots caused by the phytopatogenic fungus Entylomaster dietelianus (Bubák) Vánky & R.G.
