Horticultural & Botanical History

‘This very beautiful species of Echinocactus was first described by Dr. Lehmann, (to whom our Glasgow Garden is indebted for the possession of the plant,) and afterwards was well represented in Link and Otto’s excellent publication on the plants of the Berlin Garden.  It is a native of Brazil: and like all its tribe should be cultivated in a warm and dry stove, and the pots kept well drained from moisture.  It blossomed with us in July, 1831.’  [BM t.3107/1831].
