networks were further contributory factors.
The remainder of the surviving material, including the Willdenow
Herbarium, the fern herbarium, the private herbarium of
Joseph Bornmüller, purchased in 1938 but still in Weimar, as well
as the newly acquired Gross Herbarium, provided the basis for a
new start. From 1953, with the resumption of the publication of
the institution’s own journal and a monographic series, the international
publications exchange programme began once again
to play an important role in the acquisition of periodicals. In the
following years pre-existing collections and libraries tended to be
acquired in preference to the undertaking of collecting trips.
By the 1970s, when expeditions to Togo, and later to the eastern
Mediterranean, to Yemen and to Cuba built on old traditions,
the political, ecological and scientific parameters of collecting had
changed. Many blank spots on the botanical map had in the meantime
disappeared, and international agreements increasingly
guaranteed the claims of countries of origin.
Nowadays plants are collected in the context of co-operative
undertakings with the institutions of the originating countries.
These activities are strongly project-based and always in clearly
circumscribed areas. At the same time, in an ever more targeted
and thereby more sparing way, only those samples are taken that
appear necessary for the particular research project and the particular
enquiry at hand.

It is certainly the case that today’s holdings of books and journals
as well as of living plants exceed pre-1943 levels, whether
this also applies to the herbarium, which currently numbers 3.5
million specimens, remains doubtful. HWL
