36 A Bryological Excursion to Ben Lawers. [Sess, 
last showing fruit. The plant itself is rare, being only found 
on very high mountains, but to find it in fruit is still more 
rare. Hypnum sulcatum was also found here. We saw, 
besides, Thymus Chamedrys in bloom, a small Veronica, a 
Myosotis, Polygala vulgaris, Campanula rotundifolia, and Sax- 
ifraga cernua, Salix herbacea was growing on the highest 
peak: a plant of it I gathered, which might have been twenty 
or even fifty years of age, was so small that it could be covered 
by a penny piece, and there were male catkins on it. I forgot 
to say that we gathered a small plant of Loiseleuria procum- 
bens, or native azalea, on our way up. These were not all 
the plants on the top of the mountain, but it did not occur to 
me to make a list. 
About 8 p.m. after an hour on the top, we retraced our 
steps. On the way we gathered Tofieldia palustris, but very 
few mosses. We reached our camp about 10 p.m., kindled a 
fire, and made supper. While our kettle was boiling we 
arranged our collection, and in due time lay down and enjoyed 
a fairly good night’s rest. I awoke at five o’clock next morn- 
ing with my back nearly roasted by a large fire which Mr 
Scott had replenished about an hour previously. After break- 
fast we again secured our stores against any stray wanderer, 
and started up the Lawers burn, our destination being the 
glen and small loch (Lochan-a-Chait) at its source, a fine view 
of which we had from the summit the previous evening. We 
thought it a good hunting-ground, and it proved to be so. It 
looked quite near, and we expected to reach it in about an 
hour, or an hour and a half at most. But after getting to 
the loch we found we had been five hours on the way. We 
had not, of course, been idle, and up the burn side we found 
many fine specimens, including Weissia trichoides, Bryum 
elongatum, B. filiforme, Hypnum ochraceum, H. sarmentosum, 
H. fluitans—this in fruit—and many others. About two 
miles up the burn I got what I consider my best find, Bux- 
baumia aphylla—a moss I had never before seen, although I 
had looked long and often for it. But it was not for this I 
was looking when the small and curious capsules caught my 
eye. I thought it a strange-looking fungus, and resolved to 
take a few home to Dr Watson. While taking out a tube to 
carry it in, I stooped down to get a better look at it. The 
next moment I was up, and with hat in hand was cheering at
