Haworthia koelmaniorum var. macmurtryi (C.L. Scott) M.B. Bayer 
Quite a bit different looking with a lot of leaf texture, when compared to its twin DEM 254-A. Haworthia koelmaniorum var. macmurtryi gets my vote as the slowest growing Haworthia. At 6 years old, this little guy is just starting to grow. The stones in this photo are about 1/4" (6mm) in diameter. I hope to see this as a mature plant sometime before I die!
