Erigeron sp.

 
 
 

The predominant rock of the upper Slim Creek, Nichols Creek and Griswold Creek areas is granite.  The granite screes and acid soils of the lower reaches are home to a number of plants that we have not normally encountered elsewhere.  These include various ranunculus and erigeron species.  The feature plant was found only in the granite screes of the glaciers that lie above Slim Creek and Griswold Pass, in locations not far removed from the ice packs.  There are numerous other glaciers in this area and this plant might well be found throughout the region.  These erigerons are small with the flowers rising little more than 6 cm from the ground.  There is some variation in colour of the flowers when in bud but the three plants we saw all opened white.  As seen in the photographs, the flower buds are purple and woolly with white hairs.  The plant is similar to Erigeron humilis but is somewhat smaller with different shaped leaves and does not have the purple wool.  It may be allied with, or a variant of, the more northerly species, E. purpuratus, a plant that is quite similar in appearance but has purple-coloured hair covering the flower buds.  We would be pleased to hear from anyone who can identify the plant.
