Identifying crypts has to be the one of the hardest tasks that there is. I just have to rant about my confusion after trying to figure what crypt I have. There seems to be so much variety within the species that it is almost impossible to identify without the flower. Natural hybrids cause even more confusion to this.
I am sure that the crypt in the picture is either Blassi, Beckettii or Wendtii- would anyone be able to narrow it down from the picture? The leaves seem to vary on the plant but it looks like the cordate leaf base and the narrow lanceolate shape are the dominant features. When I bought it, the plant had very light green leaves and now the leaves are a very dark green. The underside can be purpleish red though all that remains is just the red veins because of it being in 20g with no care for a year.
I have tried using Kasselmann's book but the descriptions for Beckettii and Wendtii are very similar. I have placed one of the bigger plants into a terrarium just to see if it flowers in a few months.
When I bought the plant, I remember seeing Cryptocoryne Usteriana labeled on the tank with the miscellaneous plants. Now I wish I bought Usteriana(gorgeous plant) instead of this!
