208. RUBUS. 

 In this Genus, and in Rosa^ the species ran 



so much into one another, that it seems impos- 

 sible to draw a clear and definite line between 

 two species, in almost any part of the series ; 

 and yet, the various forms under which we 

 meet with them differ so widely as to prevent 

 us from uniting them aU under one head. I 

 have endeavoured in both genera to charac- 

 terize the most remarkable forms, without at- 

 tending to aU the intermediate gradations ; and 

 I recommend the student to begin by making 

 himself master of these prominent forms, and 

 rejecting all specimens which he cannot refer 

 to one or other of them. When his eye is 

 become familiarized to these, he may investi- 

 gate the subject more minutely, and with a 

 better chance of success than if he had at first 

 perplexed himseK with their endless varieties ; 

 and if he can hit upon more precise and defi- 

 nite characters to separate the species, he will 

 do an essential service to the science. 



The principal difficulties in this Genus occur 

 in the tribe which has a tendency to produce 

 digitate L. These are not always produced ; 

 but the student wOl soon find it easy to dis- 

 tinguish the plants which belong to this divi- 

 sion. One mode of growth is common to all. 

 The Root sends out a strong shoot, which 

 the next year produces flowering and other 

 branches, and, fixing itself in the ground, not 

 unfrequently takes new root. When this is 

 done, the L. near to the new root begin to 

 turn back. The description of the Stem and 

 L. is taken from the middle of a strong healthy 

 shoot of the year, and the shape of the Lt. 

 from that of the middle one. Where any other 

 part of the plant is alluded to, it is distinctly 

 mentioned.
