158 HISTORY OF BRITISH ZOOPHYTES. 
** New buds and bulbs the living fabric shoots, 
On lengthening branches, and protruding roots. 
Or on the father’s side from bursting glands, 
Th’ adhering young its nascent form expands ; 
In branching lines the parent trunk adorns, 
And parts, ere long, like plumage, hairs, or horns.”
