Description
Astrophytum myriostigma cv. Hakujo Fukuryu cristatum is a very nice crested cactus derived from the standard Astrophytum myriostigma cv. Hakujo Fukuryu. There are several crested forms mainly selected by Asian growers.
Astrophytum myriostigma cv. Hakujo Fukuryu is the result of crossbreeding between two of the most famous Japanes myriostigma cultivars Astrophytum myriostigma cv. Hakujo and Astrophytum myriostigma cv. Fukuryu (type B) nudum and shows some interesting intermediate features of both the parents. These hybrids have inherited by ‘cv. Hakujo’ the felty line between contiguous areoles so it seems like the areoles are connected with each other and by ‘cv. Fukuryu’ the many irregular (more or less prominent) “warts” between and on the ribs surface that cuts the continuity of the ribs and the plants appears decorated with a design which is raised above the surface. Apart for the white felty line on the ribs and on the larger warts the plant has a green nude epidermis.
