For a week now I have been accompanying a team from the Jardín Botánico Nacional and Kew’s Millennium Seed Bank on a field trip to collect seed of plants endemic to Hispaniola for banking at the Jardín Botánico and Kew. I have been taking advantage of this trip to collect nettles but also to learn how to harvest and bank their seeds. The Greater Antilles which includes the Dominica Republic / Hispaniola is a centre for species diversity for nettles and most of the 100 or so species found here are found nowhere else. Given obvious pressure on the island’s forests both in the Dominican Republic as well as in Haiti, banking their seeds could support their reintroduction as a last ditch attempt to prevent their extinction.
The seed bank at Kew which banks the seeds of >50,000 species currently has only 14 sp of nettle which for me seemed a little on the low side given that there are about 2,000 species Worldwide. Support from the Bentham Moxon Trust is helping me to increase this figure significantly, both by enabling me to help develop seed-collecting protocols for nettles and so encourage seed banks to collect them, but also because I am learning from them how to collect seeds, something that I can do myself on future fieldwork in collaboration with other seed banks.

I have just spent an amazing week with a team from the Jardín Botánico Nacional Dr. Rafael M. Moscoso and Kew’s Millennium Seed Bank collecting nettles in the Dominican Republic, thanks to funds from the Bentham Moxon Trust. The Dominican Republic represents half of the island of Hispaniola, the other half being Haiti. Thanks to a rich geological history, varied climate and very high mountains (to 2,760 m) the country is host to a very rich and diverse flora of over 5,500 species, many of which are only found on Hispaniola. We made some very interesting collections, the first two on the first day! One was of a genus, Rousselia that I have never before seen alive and of which few collections exist in herbaria, and which by coincidence I posted about a couple of months ago. The other was of a very unusual tuberous species of Pilea, a genus of ca 715 species of mainly succulent herbs, over 70 of which are found only on the island of Hispaniola.
