Seeking nightshades in South America

After a fantastic couple of weeks here in Argentina tomorrow we head for Peru, and more solanum hunting. We have spent the last few days since returning from the field in the herbarium here in Córdoba - a real treasure trove. We have added some 800 new records to the Solanaceae Source database - some very old specimens, but all new to us! Field work is great for sorting some problems, but the herbarium can bring specimens together in a way so that all the variation is laid out in front of you to see and decide what to do!

 

We have solved a number of knotty problems - realised that some of the species we were confused about were in fact only variants of a single widespread species - Solanum salicifolium - that can grow just about anywhere. Feels good to have sorted that out.

 

Tiina has gone out dancing with the post-docs - Gloria and I are making sure everything is in order for our joint treatments of Solanum for the Flora of Argentina, and generally just catching up. The list of things we will leave to do "next time" just keeps getting longer; it is clear there will another field trip next year, we are hopingn to go to Patagonia. We will be sad to leave this wonderful country and out great friends, but are looking forward to Peru, where we will arrive just in time for the Museo de Historia Natural's birthday party!

 

More solanums await in Peru - first we must sort out the permits for collection in Lima..... I am sure surprises await!

Cordoba, Argentina....

Sandy:

 

I am here at last; flying over the Andes this morning from Santiago in Chile was amazing - beautifully clear and I could see all the glaciers and snow-capped peaks. Not much snow now because it is summer here....

Cordoba is a beautiful town, a brilliant mixture of old colonial and new. The University where the herbarium is located is near the centre of town, we went over there this afternoon to have a look around. They are experiencing a heat wave in Cordoba - it is approximately 30 degrees and VERY humid! I am catching up on all the adventures Tiina and Gloria have been having last week - I'll had over to her now for the update!

 

Tiina:

 

It was great to get Sandy here with us to sort out some issues with Solanum! Like Sandy says, it's extremely hot and humid, which is why we've also had some big storms this week. A few days ago it was raining ice balls - yes I mean ICE BALLS!

 

I took pictures as proof of how bad it was: we had to mop water from the floor as the roof and windows were leaking in the herbarium! It was a real mixture of ice the size of table tennis balls, and massive rain.

 

It just goes to show that it's not easy to keep up a museum in tropical countries... While we were busy mopping water from the floor, the storm knocked down a large tree just outside. The sound was tremendous! Gloria and I went out to see the damage afterwards.

The challenge of the coming days is to fit everything in. We have meetings to talk about our recent results, our work with molecular phylogenetics and taxonomy at NHM, and cytogenetic and taxonomic work here in Cordoba. It's a great chance to throw some ideas around, discuss what we have and plan future work.

 

We also have to plan the route for our longer trip in the north. We are heading to the big Andes on Friday, to the departments of Jujuy, Catamarca, Tucuman and Salta. There are many species we want to cover, and we can gather localities where to find them from the herbarium and our existing online Solanum database.

 

During the weekend we did a short 3 day trip around the departments of Cordoba and San Luis and managed to find species which were previously only known from types. The three species we found in the field can now be studied in detail together with the original descriptions to fully understand the species.

 

Now off to bed, we are gathering strength for what's ahead! Thus far 253 specimens fully databased, c. 400 identified, and more to go!
