184 ON BRACHYCHirON POPULNEO-ACERIFOLIUS. 



trees. Brachychitons have been distributed for many years, 

 perhaps over a century. We obtain the seeds from various sources, 

 from private donation, and from our own collectors. Seed received 

 as B. acerifolius or B. popidneus would be sown under that name, 

 and nothing would be easier, in a large nursery stock, than to pass 

 over a few hybrids (obtained we do not know whence, as the 

 seeds of the same reputed species are not kept separate unless 

 there is reason for so doing), especially as the plants are young, 

 and the fact that a hybrid has been received would, by most 

 people, only be noticed when it displayed its flowers. It is in 

 the highest degree unlikely that the Mulgoa and Parramatta 

 trees were not received from the Botanic Gardens, and the same 

 remarks apply to the trees scattered through the State. Neither 

 B. acerifolius nor B. pojndneus occurs naturally in the Mulgoa 

 garden; I believe that any trees of these species in the neigh- 

 bourhood were introduced (probably from the Botanic Gardens), 

 as I believe the hybrid was.
