f. atrorubens 'Akai Ryu' ('Red Dragon') - leaves, petioles, and mostly red, greener in winter or when not vigorous.

Clumping Group (Rosetted, rosette form) - plants form numerous, very distinct rosettes

'Cropped Teeth' - teeth look as if abruptly cut or truncated, fused or flat at the apex rather than sharp.

'Cross Teeth' - a curious mutation with very long cilia-like teeth. Some of these teeth overlap or cross

'Cup Trap' - another bizarre mutation with the trap fused or sealed at one end, resulting in a more round or cup-shaped trap.

f. dentata = Dentate Group

Dentate Group (f. dentata) - teeth very short, sharp, not cilia-like, variable, various clones are named

Dentate Group 'Dente' - one named clone of the group

f. atrorubens 'Dingley All Red' - as the name suggests.

'Dingley Giant' - plants 8-10 in. wide, petiole very (1.5-1.75 in.), a very large clone

'Dirk Venthan's Giant' (G14) - a very large clone

'Double Trap' - 2 traps fused lengthwise on most of the shoots. A rare but repeated mutation.

Dutch Group ('Dutch form') - a general name for some dutch plants, descriptions seem to vary and it is not well characterized yet.

f. erecta - petiole and leaves more erect, upright, often greater than 45 degrees to the soil

Dentate Group 'Fang' - very long teeth, trap is red and showy

f. filiformis - petiole is very thin, narrow, and not winged.

'Fine Tooth' - teeth very fine and narrow.

'Fused Teeth' - some teeth are fused together, sometimes giving a web-like appearance

'Giant' - very much larger in all parts, traps to 5cm long

'Green Dragon' - green trap, showy red petioles

Dentate Group 'Jaws' - large teeth, huge trap is red inside, vigorous, reliable clone

f. linearis - a listed name.

'Long Red Fingers' - teeth very long, cilia-like and reddish.

'Low form' = f. prostrata

f. prostrata 'Low Giant' - a prostrate type but larger in all parts, petioles very wide and covering into a dense mass of foliage

f. atrorubens 'Marston Red' - a good red clone

'PInk Venus' - richly tinged reddish-rose throughout, a nicer color than the dark red by some opinions. Tends to be semi-prostrate to mounded.

'Pompom' - bizarre mutant with fasciated, clustered traps which appear as bristled or dense heads (non-functional for bug catching). The true 'Double Trap' has just 2 traps and will open.

f. prostrata 'Paradisia' - low, flat plant, traps with faint pink inside

f. prostrata (low form) - leaves, petioles, and traps all lying flat on the ground, seldom erect

'Red Border' - a listed name.

Dentate Group 'Red Piranha' - long sharp teeth, mostly red throughout

Clumping Group 'Red Rosetted' - numerous dark red traps, plants form many rosettes

f. atrorubens 'Regal Red' - very dark red, but less persistant than one clone sold as 'Royal Red'

f. atrorubens 'Royal Red' - all dark red except margins of the traps

Dentate Group 'Sawtooth' -  2-4(5) times denticulate, numerous teethlets per larger tooth, often producing a fringed effect, resembling a professional multi-toothed sawblade, trap reddish

Dentate Group 'Shark's Teeth' - teeth are larger and wider than most in this group.

'Spider' - teeth are very filiform, petioles are long and narrow, it is an erect plant

'Slack's Giant' - a good named clone that is larger in all parts

'South West Giant' - another one of the large clones.

'Toothless' - lacking teeth or cilia. Probably the same mutation as 'Clamshell'(?).

'Trifid Trap' - long teeth, trap very red inside but green elsewhere

[variegated forms] - mutations with white chimera covering half or less of the plant are reported. Some shoots have entirely white traps and leaves that survive only if enough of the plant is green and photosynthetic.
 
f. viridis - mostly or entirely green. 'All Green' is an extreme clone.

f. viridis Yellow Group - a subvariant of the all green sort that is distinctly yellow-green to chartreuse. They contrast nicely with red and greener sorts.
