H. CANNELL & SONS’ LIST OF CACTI

MAMILLARIA. 
It would be very difficult to find any plant in the whole vegetable kingdom so 
symmetrically beautiful as the Mamillaria. Strangely beautiful indeed are most of the 
varieties with their neat rosettes or stars of spines and the rosy yellow and white flowers, 
which are generally followed by small berry-like coral-coloured fruit, it is not surprising 
that they have become great favourites with cultivators of Cacti.
