Alfred Lau described 8 forms of M. huitzilopochtli to which he gave his field numbers 066, 066a, 066b, 1495 (the brown curly spined form known as ssp. niduliformis), 1500, 1557, 1558 and 1586.
I am looking for information about the last three forms. Specifically if they are in cultivation anywhere? And fairly obviously if anyone knows of seed for sale or better still, plants. But primarily it is information at this stage.
