April, 1852. Dr. Hooker 5
In New Zealand Tasmania. Sweet Briar & Sowthistle come up most extensively where new soil turned up by side of roads. Mr Gunn believes they are subsequently smothered by aboriginal plants.
Aster very variable in every part of world, as is Salix in whole Northern hemisphere & Senecio everywhere.
Rosa, Rubus Salix the largest Europæan genera & most variable.— Rubus not variable in Himmalaya as in Europe.—
In New Z Ta New Zealand, an Epilobium (a most variable genus) has which appears distinct has vars, not to be distinguished from some British species. Hence Hooker admits with Asa Gray, that in some case, though intermediate forms are obtained, yet species may be kept distinct. These species thus vary with English plants in N. Zealand. 5
