Sansevierias: Collection Dr. Horst Pfennig                               

 

Introduction

 

Apart from his profession, my husband was interested very early in the genus Sansevieria. When he discovered that there was only very little literature about this kind of plants during the 1960’s he decided to study them more closely and to collect them.

In the beginning, he managed this by contacts to other collectors and botanical gardens (Pf 0001 – Pf 0247). From 1971 on, he travelled to East Africa (Kenya, Tanzania, Uganda und Ruanda) in order to collect these plants – as well as other succulent plants and orchids – at their original locations (Pf 1001-Pf 1743):

After my husband’s death in 1994 I continued cultivating his collection (about 270 plants from different origins), hoping I would find a Botanic Garden or a collector interested in it. Unfortunately, lack of space as well as lack of money are problems in many botanical gardens. Moreover, there is apparently only little interest in this kind of collection in German botanic research.

So it was a lucky fate that Dr Schwerdtfeger, curator of the Old Botanical Garden in Gφttingen, approached me and offered me to give them a new home in his Greenhouses. Of course, also for him it is difficult to find enough space for them. I am very glad to know that the plants are in good hands now.

Sometime ago I began to document my husband’s work by computer. This includes slides, files and his documentation from his travels to Africa. I wanted to give interested people the opportunity to access his work. I do not mean to cause any more confusion about Sansevierias, since it is already difficult enough to determine the correct species, but rather I would like sustain his work. My husband only indicated the name of a plant in his collection, if he was a hundred percent certain about it. He even questioned the names he received from botanical gardens. Upon further evaluating the documents of my husband, I will certainly find more information that needs to be included here. Thus, the current documentation will continually be updated.

In this documentation I regard all Pf-numbers, even if the corresponding plants don’t exist anymore.

In order to distinguish my own results and efforts from those of my husband I write my own texts in italics.
