Re: Key to Plant Picture References (A,An,B1,B2,D, ...)

The letter codes associated with the plant names found in the Krib (i.e. A,
An, B1, B2, D, G, Jc, Jm, M, R, S1, S2, V, W, Y) refer to reference books
which illustrate the particular plant.

These basically represent the most recent English language aquarium plant
