CWR and medicinal species in botanic gardens
Suzanne Sharrock of Botanic Gardens Conservation International (BGCI) has left a very interesting comment on our post a couple of day ago about the overlap between wild medicinal plants and wild crop relatives. Rather than letting it languish in obscurity, I’m reproducing it below:
At BGCI we have developed a list of around 3,000 plant species that are used for medicinal purposes. Of these, we know that 1,802 are in cultivation in botanic gardens and this list can be easily extracted from our PlantSearch database. Simply select “medicinal plants” and the list of medicinal plants that are in cultivation in botanic gardens is displayed. On this list, plants that are also CWR are marked (according to a list of CWR genera). If you download the list, it can be easily be manipulated in excel so you can extract those species (164 species) that are both medicinal plants and crop wild relatives and are in cultivation in botanic gardens.
If anyone is interested, we could provide the full list of plants that are on both our medicinal and CWR lists — not just those in cultivation in botanic gardens.
Mine’s a decaff
We’re always on the look-out for examples of the financial value of germplasm collections which don’t involve some obscure and faraway disease, however nasty. So it was really nice to come across a great story about the search for naturally low-caffeine coffee, and in the Wall Street Journal no less. Coincidentally, there was also a blog post yesterday about the wild coffees of Madagascar. 1 Some of the many species found on that island are known to have low caffeine levels, but “[a]ttempts to transfer the caffeine-free property from wild coffee species of Madagascar, which produce an inferior beverage, to C. arabica have failed owing to a strong genetic barrier.”
LATER: I wonder if the recent Korean “land-grab” in Madagascar will have an effect on wild coffees and other interesting endemics.
