c. Spectahiles. Aculei caulis plus minusve inse- 

 quales; setae et aciculi breves perpauci, pili ssepe den-

It is an exception to the rule for brambles belonging to 

 the Sylvatici to have setse and aciculi : but the rule is for the 

 Spectahiles to possess them. M. Miiller, who formed these 

 groups, has failed in pointing out any good and constant 

 distinctions between them, nor have I been more successful. 

 Nevertheless the groups seem to be natural.
