these institutions, we have the best opportunity to know
what needs conservation, where the plants grow (geographic
and environmental data), and where one may find may samples
of the plant material, if these exist in some conservation
program. Larger botanical gardens frequently maintain and
propagate plants which they are willing to distribute to
other institutions upon request. Lists of these are index
semina.
There are other sources of plant material that frequently
are not recognized as genetic resource conservation but still
provide a broad range of plant material that would otherwise
not be generally available. These are the commercial seed
companies. Throughout the U.S., these companies provide
many vegetables, fruits, flowering plants and curiosities
raised for some particular interest, such as the sensitive
plant (Mimosa pudica), the telegraph plant (Desmodium gyrans),
the Venus fly trap (Dionaea muscipula), and many others. The
seed companies are not interested in long-term conservation
of genetic resources themselves, because their market demands
new cultivars with differing qualities from time to time.
They usually do not store viable seeds of those cultivars
that are no longer popular. However, these institutions may
maintain certain breeding stock which contains much of the
