Haworthia attenuata var. attenuata

Taxonomic status:Accepted

Occurrence status:Extinct

Establishment means:Introduced

Stemless rosetted herbs c. 30 cm high, suckering to form dense clumps. Leaves spreading, lanceolate-deltoid, to 13 cm long and 15 mm wide, attenuate, tuberculate. Inflorescence sparsely branched, to 21 cm tall. Bracts membranous, 3 mm long, acute, keeled. Flowers white, to 15 mm long; pedicle erect, c. 5 mm long; perianth tube funnel shaped, 4 mm diam., curved or straight; stamens subequal, included; ovary 4 mm long.   

Native to South Africa. Widely cultivated. Sparingly established in Victoria, known only from a single population near Barwon Heads which has since been eradicated.

A variable species, although only 2 varieties are recognised. Variety attenuata is distinguished from var. radula (Jacq.) M.B.Bayer by its larger, sparser tubercules. Haworthia attenuata is sometimes confused with Haworthia fasciata (Willd.) Haw. which is distinguished from H. attenuata by the lack of tubercules on the upper leaf surface.
