showing stolons. John Torrey * describes U. perfoliata as hav- 
ing “root a tuft of fleshy fibres,” and Kuntht says merely 
“Rhizoma repens ” as a character for the whole genus, and we find 
the same in Darlington’s{ and Chapman’s Manuals§. A more 
complete description has been given, however, in the sixth edition 
of Gray’s Manual, where Uvularia has been characterized as hav- 
ing a ‘‘ short rootstock with fleshy roots,” while “a slender, creep- 
ing rootstock’’ has been attributed to the genus Oakesia. 
But the fact that Vvudaria possesses long, subterranean stolons, 
seems certainly hitherto to have been overlooked. 
In Uvularia perfoliata, the main rhizome of the full-grown and 
flowering plant is hardly one line long, and is entirely concealed 
by the roots. These are whitish, fleshy and cylindrical, thickest 
at their upper extremity and then taper gradually towards the 
end; their length is from two to three inches on full- grown speci- 
mens, and they are but sparingly branched. Besides this part, 
the main rhizome, there are regularly two stolons to be observed, 
one on each side of the base of the flowering stem. Plate CXI, Fig. 
1 illustrates the rhizome of an old plant, and we see here the two 
stolons each with its prophyllum at the very base. This prophyl- 
lum is about three lines long, triangular, but sheathing for half of 
its length. The stolons are covered with long, scale-like leaves, 
more than an inch in length, which form closed sheaths around 
the internodes. The apex of these leaves is free, triangular and a 
little curved. The stolons do not run in a straight line under the 
surface of the ground, but are slightly bent at each internode. 
The end of the stolons may strike root and the bud will then de- 
velop a new plant, while the other part is entirely destitute of 
roots and fades away early in the spring. At that time the young 
plant has been provided sufficiently with roots, similar to those 
described above, and does not need any longer to be in connec- 
tion with the old individual from which it has been formed. 
Oakesta sessilifolia, The rhizome of this plant is entirely dif- 
ferent from that of the preceding. It is relatively long, about six
