490 ON THE GENUS RUBUS. 
rium Filiv-foemina, var. converum. We spied some Blechnum bo- 
reale ou the other side, so large that we determined to ford the 
stream. As we were debating about the best place to cross, a 
cow, attended by her calf, as if in scorn of our counsels, dashed 
across the stream in fine style,—at the worst only wetting herself 
with clean water. Had some of us but followed her example, we 
should have been better off, and not have floundered as we did 
into a heap of boggy mud. However we went gaily on, to a 
field, where we rested, and pulled Scutellaria minor, Hypericum 
-pulchrum, H. elodes, and the rarer H. humifusum. The large 
purple bells of our Irish Heath, Menziesia polifolia, appeared in 
profusion. At the exclamation of one of our party from a swamp 
of “anew Butterwort!” I went towards her, and recognized a 
Connemara acquaintance in Pinguicula lusitanica, m company 
with Drosera longifolia, which was not in flower, though very — 
welcome to us all, and quite made amends for our fruitless search 
for Lastrea Oreopteris.

(Continued from page 446.) 
From the forms of the plant and its mode of growth, we may 
pass on to what are called its arms. And first, of the prickles. 
These are conical, on an elongated base, curved or inclined down- 
wards, sometimes nearly horizontal, but never inclined upwards, 
unless where the plant is preparimg for itself a new root, and 
varying much in size, in robustness, and in frequency. They are 
sometimes confined, or nearly confined, to the angles of the stem, 
and in that case are all usually nearly equal, or, if accompanied 
by a few aciculi, there is no gradual passage from one to the 
other. Sometimes they are scattered over the surface, nearly 
equal or unequal, passing or not passing into aciculi. In any of 
these cases they may or may not be accompanied by sete, 7.e. 
by something stronger than hairs, but which yet cannot be called 
prickles, and each tipped, when young, by a small gland. The 
aciculi differ from setee in having no gland, and their base is in a 
slight degree longitudinally expanded, but not in the manner in 
which it shows itself in the aculei. ‘There is however no very
