Lactoris jedini i monotipski rod porodice Lactoridaceae, cvjetnica iz reda Piperales, razred Magnoliopsida, divizija Tracheophyta.[1]

Jedina vrsta, Lactoris fernandeziana je endemski grm šume oblaka Masatierra - Otoka Robinson Crusoe, te sa Otoka Juan Fernandez, arhipelaga iz Čilea.

Taksonomija

Ranije je bio smješten u Aristolochiaceae, ali od pojave APG III (2009) sada je sam u porodici Lactoridaceae, red Piperales.

U vezi s klasifikacijom roda Lactoris, morfološki podaci nisu jasni, ali molekularni stavljaju ga u Aristolochiaceae.[2][3]

Opis

Lactoris fernandeziana - 1888. botanička ilustracija.

Čini se da se Lactoris fernandeziana oprašuje vjetrom. Divlja populacija od oko 1.000 biljaka ima malu genetičku raznolikost, a raste na maglovitim i kišnim padinama, obično kao podvodna biljka, ali ponekad i na potpuno osunčanim staništima.

Uzgoj sadnica uglavnom nije uspio, a reznice su bolje rasle, pa bi bolje poznavanje preferiranih uslova uzgoja moglo olakšati uzgoj.

U fosilnim zapisima pronađen je polen koji je, čini se, povezan sa današnjom vrstom roda Lactoris.
