Another Mammillaria ID

Post by claytablet »

A friend asked me for the name of this Mammillaria that she has had for about 15 years.
It is approximately 20 cm tall and branched dichotomously at about 6-7 cm. The two heads have been growing steadily. It also blooms regularly, the photo was taken three days ago.
The spines are small straight and light coloured.

If not for the spines my guess would have been M. bocasana.

Does anyone have an idea?
Thanks
JB

Thanks!
I googled it those are the flowers but a lot less fluff.
Is the degree of fluffiness random or due to environmental influences?

Worth mentioning the difference between true "fluff", multiple fine hairs from the axil of the plant often not firmly attached, and spines which may be very fine and flexible but firmly attached to the tip of each tubercle. M. karwinskiana has one, M. bocasana the other.

When comparing pictures to your plant, look for the subspecies of M. karwinskiana since ssp karwinskiana itself is not usually very hairy and has quite noticeble spines. M. karwinskiana is also known for its bristles, tortuous hairs from the axils, but stronger and thicker than the fluffy hairs. In some cases the bristles are very numerous and give the impression of an extremely hairy plant like yours.
