Spiniferous Areoles

Coryphantha areoles are always sterile and never floriferous. The position of the areole is located close to or on the tubercle tip. Usually, areoles are covered by white wool in youth, but this disappears with age. The areole is bordered by the thickened bases of the radial spines in a more or less pectinate manner. The measurements given in the text relate to the diameter, and to the length and breadth within this boundary. The shapes of the areoles can be round or oval. In certain species the shape of the areole is dependent on whether a central spine is produced or not. Without a central spine the areole is oval, whereas with a central spine present, it is round.
