There are some comments about 'Novak' under Super Dwarf Cavendish at Dave's Garden:

Novak is registered as "Super Dwarf Banana". It is not Super Dwarf Cavendish. I have read it is a mutant of Grand Nain. It rarely exceeds 4 ft., has a thick pstem & large elongated leaves. Although it is mainly grown as an ornamental, it does produce small, very sweet fruits. There is little info on the internet. Most sites lump it in with SDC.

Some of these ornamental clones have brand names such as 'Bananarama', 'Tropicana', 'Chyla Dwarf' and at least one, 'Purple Rain' with very dark leaves, is (or rather was, the protection seems to have lapsed) protected under European Plant Breeders' Rights. 'Bananarama' and 'Chyla Dwarf' are very dwarf. The most dwarf of all is probably 'Novak' a plant with an interesting and rather sad history.
'Novak' was developed as a radiation-induced mutant at the IAEA/FAO Joint Laboratories in Siebersdorf, near Vienna in Austria. The scientist in charge of the programme at the time, and a great Musa expert, was a Czech scientist, Dr Frantisek (Frank) Novak. Frank was tragically killed in a car crash while travelling in Czechoslovakia shortly after the collapse of the Iron Curtain. The plant is named for him.
There is a variant of 'Novak' derived from tissue culture and known as 'Little Prince'. This plant was erroneously marketed as a form of Musa basjoo in the UK in 2003.
