238 LEAFLETS, 
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 Cadionta. 
One need not know that it hasany. 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, Red 
Raspberries and Black Raspberries, 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 Flora Franciscana some fifteen years since. I wish now 
to express that opinion without reserve. 
BATIDAEA (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 Jäger, Europe. 
The North American species are many, mostly hitherto un- 
recognized.
