THE COLLECTIONS OY CAPTAIN W. J. S. PULLEN, R.N., CAPTAIN W. PENNY, 
AND MR. CHARLES EDE, R.N. 
Besides the collection formed during tbe voyage of H.M.S. Herald, a number of plants were 
gathered in various parts of tlie Arctic region by Captain Pullcn, Captain Penny, and Mr. Ede; 
these have been communicated to Sir William Hooker, and lists of them have been prepared by 
Mr. W. Stevens. Though none, except a few collected by Captain PuUen, belong to the flora of 
"Western Eskimaux-land, I have alluded to them in the foregoing pages, and have no hesitation to 
annex the lists. I can only regret that the other coUections formed during the Arctic Expeditions 
Iiave not come to hand, so as to enable me to offer some general remarks on them. It will be 
obscn'cd that none of the species enumerated below are new to science, but they are interesting as 
iUustrating the geographical botany of Arctic America. Those of Captain W. Penny and Mr. Ede, 
being chiefly from countries only discovered within the last few years, are very valuable. The search 
for Sir John Franklin's expedition being still continued, it is desirable that the officers employed in 
that search shoidd, as far as circumstances will permit, collect specimens. New genera or species 
they must scarcely expect to discover, but they can confer a benefit upon science, by noting the exact 
locality in which the specimens are found. In the higher latitudes every degree is of importance, 
and it is only by carefully noticing the localities that we shall be able to ascertain the northern limits 
of the different plants.
