They will grow lower if you have more light, less shaded, same is true for a
number of plants. If you had say 4 watts a gallon or so in a 18inch deep
tank they would stay fairly short, perhaps 4 inches high. The redder "micro"
even less. It seems to get about 4 max at lower lighting but the other does
get tall. The micro is not commercially available so this is seldom seen so
far. A number plant folks have it here in the USA. I think Neil brought some
back from Japan.

Tips of the leaves are different also. Sags are/tend to be more blunt.

See Neil's article in PAM. It gives a good overview of these groups and

If it's the real C x willisii is only 2 inches or so tall. The C x willisii
lucens is about 2 times bigger but very close.

Doesn't sound anything like it.
Some very slight color in high light but I doubt this is the case here. I'd
go with your wendtii or perhaps walkeri grouping. C x willisii stays green.
Put it out in good light and see if it colors up.
