Which of these crypts is smallest?

[kb46]

Cryptocoryne sp.

lutea
beckettii
petchii
walkeri
wendtii

Are lutea and walkeri the same or is lutea a variety of walkeri?

[freshfish]

It's not C. wendtii for sure.

I think it's C. parva, though that's not on your list?

[kb46]

Yes, parva is probably the smallest crypt but I just want to know which is the smallest from that list of five. I've done plenty of searches and get different information everywhere - typical internet!!!

I think the problem is that they'll grow differently depending on the conditions in the tank... they'll even grow differently on different sides of the same tank...

[Renegade545]

It depends on the richness of the substrate but IME lutea is small. I have it growing in 4 different tanks, with the leaves averaging around 3-3.5 inches. Although some are staying smaller, and others are extending close to 5 inches.

I am going to say, from that list, C.lutea.
