Lithops - Au Cactus Francophone

This volume would never have seen the light of day if it had not
been for the support the author had received from various quarters. First
and foremost, I must express my warmest thanks to the curators of “Het Jan
Marais Nationale Fonds” for the generous financial aid they have given me
not only in contributing to the cost of preparing the coloured drawings but
also towards the publication of this book. My especial thanks are due to the
Hon. Minister of Education, who on the recommendation of the Research
Grant Board, has contributed very substantially towards the cost of publica
tion. Needless to say, I appreciate the support of the Research Grant Board
in this matter.
I wish to express my very hearty acknowledgment for the help of the
following:
Mr. Ernst Rusch, Lichtenstein, Windhoek, for valuable information and
live material.
Herr Wilhelm Triebner, Windhoek, has placed his unique knowledge of
the flora of South West Africa and material at my disposal. His information
about the distribution and habitats of the species was very valuable.
Mnr. Roux, Keimoes, for detailed accounts of the species growing in
his neighbourhood.
Dr. Henrici, Fauresmith, for information about and a photo of L.
salicola.
Herr Eberlanz, Lüderitzbucht for the loan of photos and collecting rare
material in his vicinity.
Mr. Minnaar, Vryburg, for information about L. Aucampiae.
Mr. P. van Heerden for collecting rare species from Namaqualand.
Herr and Frau Goltze, Urikos, Maltahöhe, for a photo and material of
the rare species, L. Urikosensis.
Mr. M. Otzen for material.
Dr. A. L. Geyer for valuable information and live material.
Mr. W. Giess for preparing drawings.
To Mrs. Evelyn Krämer, Knysna, I owe the deepest sense of gratitude
for the trouble and I might say love with which she attempted to place on
record the elusive colours and forms of these beautiful plants and also for
the way she responded to my wishes. The beautiful coloured drawings are
reproductions of her art.
I also wish to take this opportunity of expressing my thanks to the
University of Stellenbosch for financial aid and for publishing this volume.
