CRAVEN HIERACIA. 459 
Thistles just named, though the flowers appeared to me more to 
resemble those of C. arvensis than either. The flowers were at 
the end of long branches, springing from the axils of the leaves: 
from halfway up the stem, several, but not all, two together, but 
the top of the panicle having three or four clustered together 
after the manner of C. palustris. The stem is furrowed, very 
cottony, but not winged, only that between the origin of each 
leaf a few scattered prickles appear, with an incipient but imper- 
ject border. The leaves are very similar to those of C. palustris, 
but whiter beneath, and with weaker spines. The lower leaves, 
which are very sharply pinnatifid, are lengthened into a decurrent 
base, beset with long spines, almost as weak as hairs, so that the 
plant is handled without any difficulty. I showed the plant to 
my friend Mr. Thomas Westcombe, who has a good botanic 
garden here, and has some experience with the Thistly tribe, avd 
he agreed in opinion with me that the plant gathered could be 
only C. Forstert. 
As confirmative of its probable hybridity, the plant I gathered 
grew on the confines where C. pratensis was located and not far 
from specimens of C. palustris. There were about five stems, all 
close together, and perhaps springing from the same root, but 
this I did not ascertain, leaving the root in the soil, so that I 
hope other botanists may find it next year. 
Worcester, July, 1856. 
Revised List of Craven Hieracia, after Backhouse. 
To the Editor of the ‘ Phytologist.’ 
Sir,—With your permission, I beg leave to insert a revised 
List of the Hieracia as a substitute for the former one, and for 
which I am chiefly indebted to Mr. Baker, who, with Mr. Back- 
house of York, has so diligently and successfully studied this 
genus, concerning which, it is well known, there has been for a 
long period considerable difficulty im defining and determining 
the different species. 
In the List above mentioned I also inserted (p. 349) Orobanche 
‘Hedere (if not O. rubra) as found sparingly near Settle. Mr. 
Baker has determined it to be O. rubra, and says, in a note to 
me, “ We have found O. rubra in North Yorkshire, in a precisely 
Similar station to Aldes Scar.”
