regard to Antipodean plants which have 
long been introduced into this country, such as the 
New Zealand Todeas superba and pellucida, they 
have fully adapted themselves to our climate, and 
rise in our early spring at precisely the time when 
at home their growth would be ceasing. How long, 
however, such a change takes to т we do 
not know. Amongst our native ns we have

plants in native habitats. They often, indeed, show 
no trace of starting under glass until July or even 
August, and this with perfectly cold culture, so that 
the lateness of their starting is not to be attributed 
to growth unnaturally maintained by warmth long 
after the normal dormant period should begin. 
This case is unique in our experience, culture under 
glass inducing, as a rule, and as one would expect, 
а somewhat earlier development than out-of-doors.
