Hi there Diane, John Watson was not specific about locations, only describing collections areas in 2001. The ones covering Alstromerias were notated as A & B, where A - Chilean Northern Pacific Coastal and Inland Desert Climate - High subtropical latitude. Hot in summer, mild winters. Usually low to extremely low (near zero) rainfalls, but with exceptionally heavy rains at approx 5-10 year intervals during El Nino events. Inland diurnal temperatures are more extreme: nights can be very cold, including freezing, and atmosphere is low in humidity. Proximity to Pacific reduces diurnal and annual temperature extremes (frost free) and generally increases ambient humidity, in particular as a result of many days of damp sea fogs throughout the year. Above average precipitation and fogs increase progressively over ca 100m on the 2000m plus coastal hills. In partiuclar the high range behind Taltal and Paposo attract significant regular annual rainfall and mists, creating a high oasis which flowers more or less well virtually every year. Terrain. Dry, more or less bare, rocky hillslopes and coastal plain. Coastal shores and immediate hinterlands often consist of pure sandfields or semi-stable dunes. Altitude. 1-1300m Vegetation. Mostly concentrated in valleys, hollows, etc where any precipitation runs or collects. Also in sandy places and summit regions. Basically xeric and succulent shrubs, cacti, annuals and geophytes. B - Chilean coastal pacific mediterranean zone - Climate.Hot dry summers, partially modified by regular sea fogs; Winters and spring mild, with very variable but regular significant rainfalls, peaking at 5-10 year intervals by el Nino. Virtually frost free. Terrain. Low coastal hills, plains and valleys, cliffs and clifftop plateaux. Altitude. 1-500m Vegetation. Rich and overall. Mostly open littoral shrublands, beach and dune communities and annual-grass dominated meadows. Shrubs (often semi-xeric), cacti and succulents, perennials, annuals, grasses (mainly fairly ephemeral), geophytes and occasional trees. >9531 magnifica ssp maxima - B, inland 200-300m >9582 diluta ssp chrysantha (yellow) - B - coastal >9558 diluta ssp chrysantha (pink) - A coastal >9575 hookeri ssp cumingiana - B inland 300-500m >9578 hookeri ssp maculata - B coastal, a spot endemic >9580 magenta - B somewhat inland 400m >9604 pulchra v pulchra - B littoral >Not yet germinated: >9507 and 9551 crispata - A inland 1000m >10300 pseudospathulata - This one was from 2002, conditions V Climate. Mediterranean alpine type. Long summers, mainly hot and dry, but somewhat shorter and marginally cooler than further north in the central temperate cordilleras and punctuated by more frequent unsettled periods and mountain mists. winters are correspondingly longer than further north. Locally, summer nights are milder than for the main Talca cordillera due east. Terrain. (for this one) upper crumbled white granite fields and meadows at treeling. Altitude. 1000-2000m Vegetation upper flattened nothofagus, bunch grass and Andean flora. Hope that helps. Best regards, David Victor
