Ambrosina és un gènere monotípic de fanerògames de la família de les Aràcies. Consta d'una única espècie, Ambrosina bassii, l'aràcia més petita de la Conca del Mediterrani. Generalment se la pot trobar als vessants nord dels boscos i sobre substrat d'humus que cobreix la pedra calcària. Es troba àmpliament distribuïda a Sardenya, Itàlia meridional i Algèria.
Aquesta planta arriba només als 8 cm d'alçada, i les seves fulles són ovalades de 3,5 a 6 cm de longitud i semblants a les fulles de moltes plantes de la família de les aràcies. La inflorescència mesura 2,5 cm de longitud i es troba inclinada, tenint una espata inusual. Aquesta espata té la forma d'un ou i és de color marró verdós amb punts. L'interior de l'espata amb forma d'ou es divideix en cambres, on en una es troba la flor femenina única i a les altres de 8 a 10 flors masculines. Les llavors són dispersades per les formigues que es mengen els eleosomes adjunts a les llavors.
Aquesta espècie no està emparentada amb cap altra planta, raó per la qual és bastant singular. És també l'única de la tribu Ambrosineae.
Ambrosina basii va ser descrita per Linné i publicada a Genera Filicum 6: 517. 1764.[1]

Ambrosina is a genus in the family Araceae that consists of only one species, Ambrosina bassii, and the only genus in the tribe Ambrosineae. This species is the smallest 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.[3][4][5]
Ambrosina bassii has oval leaves that are 3.5 to 6 cm long and resemble the leaves of many aroid seedlings. The inflorescence is 2.5 cm long bent over and has an unusual spathe. The spathe is shaped like an egg and is greenish brown with dots on it. Inside the egg shaped spathe is divided two chambers. In one chamber is contained a single female flower and in the other are 8 to 10 male flowers. The seeds have an elaiosome.[6] However, seeds are rarely formed, as this species exhibits a low reproductive rate.[7]
The inaperturate pollen grains are 26-50 µm big. It disperses as a single grain (monad).[8]
Ambrosina is the only representative of its genus and is quite unique. It has been shown that it has high heterozygosity, as it has an average of two loci per allele. The data represents that genetic variation attributes to differences among populations from different geographical territories. Also, the local anthropogenic fragmentation has caused no time for genetic drift or interbreeding to erode genetic variation, this eventually resulted in generating differences between populations.[9] The effective population size is low in natural populations.[7]
It is closely related to the genera Arisarum, Peltandra, and Typhonodorum. Ambrosina is the sister group to Arisarum, from which it separated about 46.1 Million years ago.[1]
The precise relationships are displayed in the following cladogram:[1]

The genus is monotypic and only consists of Ambrosina bassii.[3]
The following three varieties have been described:[3]
However, none of them are accepted.[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]
The seeds are attractive to ants, as the seed is coated in an edible elaiosome. Due to this edible coating, the ants disperse the seeds.[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. Shivas (syn. Entyloma dietelianum Bubák[14][15]). Numerous 10-16 µm large spores are embedded whithin the leaf spots. This fungal disease is specific to the family Araceae.[16][17]
The generic name Ambrosina honours the brothers Bartolomeo Ambrosini (1588-1657) and Giacinto Ambrosini (1605-1671).[18]
Despite being listed as species of leaft concern by the IUCN Red List of Threatened Species,[2] it is legally protected in France.[19][2]
