and distinct stripe, than it had when it flowered in the autumn after its impor- 
tation. Its pollen appears to be quite sterile. The mule C. scabro-erubescens, 
mentioned in that article, has also flowered since, and differed from C, submer- 
sum in nothing but a red tinge upon its scape and spathe, which belongs to 
the variety of erwbescens, from which it was raised, and rather brighter stripe 
on the petals. The difference between them was less than between that 
variety of erubescens, and the one that was found in company with submersum. 
We consider the fact of C. submersum being a natural mule between C. eru- 
bescens and scabrum, generated in the wilds of Brazil, to be indubitable. 
We scarcely entertain a doubt of C. amabile and augustum having been pro- 
duced in the same manner between zeylanicum, and two different columnar 
species.  W.H. .'
