and inflorescence alone, and from this there seems to follow 

 necessarily the conceding of equal rank to what I shall call 



Callionia. Perennials with typically a solitary slender 

 stem ascending, never erect, bearing about two long-peduncled 

 flowers, one in the axil of as many middle stem leaves, the stem 

 after flowering becoming greatly elongated, trailing and sarmen- 

 tose. Calyx rotate in anthesis, the 5 bractlets equaling or often 

 quite surpassing the segments, their tips often seen projecting 

 beyond the summit of the broad rounded petals. 



Let no one wrestle with any supposed etymology of Callionia. 

 One need notknowthat it has any. Itis an euphonious designation 

 of what to me is the most charmingly modest and beautiful 

 of our potentillaceous types. The species are, at least in part,

We have, in the eastern United States, three groups of shrubs 

 which, in colloquial speech, we distinguish as Blackberries, Eed 

 Kaspberries and Black Easpberries, the latter otherwise known as 

 Blackcaps. The old ruling, that these three very natural groups 

 should be but sections of one genus, Rubus, I have long submitted 

 to with mental reservation. A hint of my real opinion was given 

 in my Elora Pranciscana some fifteen years since. I wish now 

 to express that opinion without reserve. 



Batidaba (Dumortier, as subgenus.) Stems the first season 

 erect, armed with straight prickles (usually soft and innocuous 

 in Eastern species), and clothed with pinnately 5-7-foliolate 

 leaves. Flowers inconspicuous; petals small, dull-white. Fruits 

 separating from the receptacle; drupelets rather many, soft, very 

 juicy and perishable ; pyrene reticulate, obtuse and without 

 keel on the back. Best known species Rubus Idaeus, Europe. 



The North American species are many, mostly hitherto un- 

 recognized.
