Recent sights of Chilean geophytes

Mark Akimoff and I have just returned from 2 weeks in central Chile. The 
country is experiencing a severe drought, with associated overgrazing of 
the few sites that retain moisture, so we didn't see the range of plants 
I had seen when visiting these sites in other years. However, some 
geophytes were flowering bravely. At La Parva, a ski area above 
Santiago, many Rhodolirion (or Rhodolirium) were in full bloom. I don't 
know the current name of this species, which used to be Rhodophiala 
rhodolirion. Elsewhere we saw Rhodophiala andicola (deep pink) and R. 
montana (yellow). Alstroemeria umbellata and A. exserens appeared well 
also above Santiago, and A. aurea was frequent in the lake district to 
the south. We found Tropaeolum polyphyllum and probably T. sessilifolium 
in the Santiago ski areas, flowering in vertical crevices where the 
cattle could not get at them. Sisyrinchium spp. also were doing well. 
However, cattle and goats had eaten everything that's not spiny or 
poisonous, or too tiny to notice (e.g. Chaetanthera); I hope the 
rhizomes and bulbs survive several years of such mistreatment and emerge 
once more. A lot of Chile's many national parks and reserves are grazed, 
despite prominent signs promoting environmental consciousness. In 
addition, the ski areas, which used to be a great resource for summer 
botanizing, are now far more developed than when I began visiting them 
in the late 1990s. Another disappointment was the Termas de Chillan, 
where an earthquake a few years ago caused a massive landslide that took 
out the old spa hotel (now replaced by an ugly modern one) and rerouted 
the stream above it, where one could once see a beautiful flora. The 
formerly walkable slope that hosted a remarkably varied population of 
Alstroemeria aurea is now very steep.

At this time of year I would have expected some of these amaryllids to 
be in seed rather than in flower, particularly because we were told that 
the snow had melted in October or even September. However, we saw no 
seed capsules.
