The great Benthamiella hunt  - Patagonia Day 3

Posted by Sandy Knapp on Jan 22, 2013 12:52:51 PM

This was the day when the plants were to begin – again though we began by driving a very long way! Our destination was the Pampa del Castillo where three species of the Solanaceae genus Benthamiella had been collected - old collections, but these plants are very rare and we are trying to hit every locality in the hopes of finding at least some of them. Benthamiella is a genus that is endemic to Patagonia, with 12 species in Argentina and Chile. These are tiny cushion plants of the steppes, hard to find!

As we drove south the landscape became more and more desert-like, the plants lower and lower and drier and drier. We began to see guanacos along the road, grazing in the weeds, and also in the native vegetation. These camelids are the wild ancestors of the “cultivated” llamas and alpacas of the Andes and are absolutely beautiful – they look like proper wild animals, sleek and beautifully colored.  Petrol stations are few and far between in Patagonia, so every time one appears everyone tries to fill up, there are always queues!

Petrol queues in the middle of nowhere!

 

We turned off for Pampa del Castillo, and began to search the steppe for Benthamiella. We found lots of interesting things, and it was very hot!, but no luck. The sight of four botanists, heads down looking at the ground must have looked absolutely crazy! The only creatures that would have seen us were rheas though – the area was absolutely deserted.

You can just make out Juan, Franco and Gloria heads down searching the steppes for Benthamiella!!

Rheas - the epitome of avian elegance, and not the slightest bit interested in us....

 

We drove and collected and drove – all the way to what was on maps as the town of Holdich – abandoned long ago. It must have been so difficult living in this dry exposed area – today it is a large oilfield, full of “grasshoppers” extracting black gold…..

This abandoned house had a deep basement and was full of beautiful old tiles - it must have been quite some residence at one time.

 

In a last attempt, we stopped at the last locality – not hoping for much – but success at last! Two species of Benthamiella! The flowers were less than 4 mm long, and dried up and almost falling off – we wondered if we had just walked by these plants earlier. Once you get your eye in for a plant, it appears everywhere – let’s see if we can find Benthamiella more efficiently tomorrow!!
