Description
The name “Mammillaria cylindricaSN|9140]]SN|13782]]” persists in cultivation when clearly the identity of the plant described is extremely vague and unreliable. Possibly it is a form of Mammillaria spinosissina with less but stronger spines reddish-brown central spines.For example
Axils
Little setose.
References
172, 1922 sayMammillaria cylindricaSN|9140]]SN|13782]] Hitchen that appeared first, published by Forbes (Journ. Hort. Tour Germ.147, 1837) but was so briefly described that it can not be identified Hunt, in Bradleya, A new review Mammillaria rnames 1128, 1983 Refers this plant of Mammillaria coronario that the name persists for a member of the Mammillaria spinosissima group, but that the plant in question was probably not a Mammillaria at all, being described as 150 cm tall. That leaves the reference to Mammillaria eriacanthaSN|13782]]SN|9140]] as the only name in popular use today.Flowers colour is magenta..
Note
This species has been referred by various authors to both Mammillaria coronario andMammillaria eriacanthaSN|13782]]SN|9140]] but it differs from both. Cactus cylindricusSN|4085]]SN|4085]] Ortega (Nov. Rar. Plant., 128, 1797) is not referable here as the radial spines count is less and it has milky sap.
