CHAPTER XVIII.

DEALERS IN CACTUSES.

The difficulty experienced by amateurs in procuring plants of many kinds of Cactus has suggested to us that a list of some of the principal dealers in these plants would prove of service to English growers.  So far as we know, there is no nurseryman in England who makes a specialty of Cactuses.  Plants of such well-known genera as Epiphyllum, Phyllocactus, and Cereus in part, may be obtained in England, but for a collection of representative kinds we must perforce apply to Continental nurserymen.  The most reliable of these for Cactuses are: 

Germany.

Messrs. Haage & Schmidt, Erfurt.

Herr F. A. Haage, Junior, Erfurt.

Messrs. MUeLLER & Sauber, Kassel, Hanover.

Herr H. Hildmann, Oranienburg, Brandenburg.

Herr Ernst Berge, Leipsic.

France.

M. Eberle, Avenue de St. Ouen, 146, Paris.

M. Jamin, Rue Lafontaine, 42, a St. Ouen, Paris.

Belgium.

M. Louis de Smet, Ledeberg, Ghent.

M. Bettes, Borgerhont, Antwerp.

M. F. VERMUELEN, Rue Van Peet, Antwerp.

America.

Mr. C. Runge, San Antonio, Texas.

Messrs. Reasoner Brothers, Florida.

SPECIES INDEX

Species are listed alphabetically according to Watson’s nomenclature.  The name(s) that is more likely to be recognised by modern readers is listed in brackets.  I have used Anderson’s book—­The Cactus Family (Timber Press, 2001)—­as my main guide.  Monographs by Craig and by Pilbeam were invaluable in identifying ‘Mamillarias’.
