Touching the sky.....

Posted by Sandy Knapp Feb 22, 2012

Well, we did make it to the puna – and all there is to say is – wow. We first climbed from 1200 m above sea level in the town of San Salvador de Jujuy up the Quebrada de Humahuaca to 4500 m at the Abra de Lipán – up an incredible road. Unlike most of the roads we have been on this trip though, this one was paved – it is the road to Chile over the puna.

Once over the pass we felt like we could touch the sky – it was amazingly clear and you could see for miles. Distances are hard to measure at these elevations – everything looks quite close. The snowy peaks we could see in the distance were in Chile! It looked as though they were right there…..

As we looked for solanums at high elevations a storm gathered…. We found our friend from Catamarca – Solanum chamaesarachidium – but this time in miniature, who could believe a plant so tiny could reproduce. That is, however, what plants and animals do; this plant has a flower and a developing fruit - amazing.

It started to rain, so on we went, heading to the tiny village of El Moreno, where Gloria had once before seen Solanum sinuatirecurvum, another high elevation speciality.

We found the plant, got very excited, climbed the fence to photograph it – but then the storms gathering all round caught us up and thunder and lightening began, accompanied by hail. Now a bit of bad weather never really deters plant collectors, but being the tallest thing for miles in a lightening storm is not a great idea – so we got in the car to wait it out.

After the storm we talked to some of the residents of El Moreno – imagine a place where water takes ages to boil, and the only fuel is wood – but there are no trees. Interestingly, the man we spoke to had a solar stove for boiling water – he said it took 25 minutes to boil 5 litres of water – using only sunlight – something there is plenty of high up in the puna.

We then began the drive back through the puna to return to the town of Purmamarca for the night, seeing more vicuñas on the way, plus several other exciting plants. The main road to Chile goes over huge salt flats (the high Andes is full of these salt pans or salares) so we took a quick detour to see them. Optical illusions abound in places like this – the far-away mountains looked as though they were floating on air.

It was a day of wonderful plants, amazing views and great fun. We spent the night in Purmamarca where we ate at a place with live music – Tiina learned to dance the chacarena – a local Jujuy dance, and the music was great. What stays with us still though, is the pure beauty of the weather in the high Andes – we were surrounded by storms all day, but never really got wet; what we saw was an ever-changing sky so close it felt like you could touch it.

Cordoba, Argentina....

Posted by Tiina Feb 8, 2012

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!
