Alocasia tandurusa Prameswara & A.Hay, A new (bi)pinnatifid-leaved species from Sulawesi [Araceae, tribe Alocasieae (Schott) A.Hay], with notes on tribal classification for the paraphyletic grade of ‘Old World Colocasioids

 

Alistair Hay & Prameswara

 

ABSTRACT

A new species of Alocasia from Sulawesi, Indonesia, already in horticultural circulation internationally for some years, is described and illustrated. It is ascribed, in view of years of molecular-phylogenetic consensus on relationships amongst the old world elements of Engler’s Colocasioideae (now viewed as a paraphyletic basal grade of the Pistia–Dracunculus Clade), to the tribe Alocasieae (Schott) A.Hay, a taxon newly raised to tribal level here. The tribal classification of the genera involved is outlined, and the new tribe Englerareae A.Hay is also established. Key words: Sulawesi, Bolaang Mongondow Regency, Pisteae, Protareae, Englerareae, Colocasieae, Alocasieae.
