BOTANY OF THE AZORES. 
I then took only two small lateral branches, under 
the expectation of returning to the locality at a 
later season ; though in this I was disappointed. 
It is a very large species, probably exceeding

Raised in my garden, from the seeds brought 
home, the plants are altogether so intermediate 
between P. maritimum and P. Raii (Bab. in Linn. 
Trans. Vol. 18, p. 458 and Eng. Bot. Supp. 2805) 
that, if their descent were unknown, it would be 
bighly difficult to refer them to either with cer- 
tainty. This seems almost to establish the 
specific identity of P. maritimum and P. Raii, 
different as these plants undoubtedly appear in 
the absence of the intermediate forms.
