ADDITIONS TO THE WYCOMBE FLORA. 155 
The very curious variety of the Water-cress (Nasturtium 
officinale) known as JV. sizfolium, has been seen by the stream in 
the Rye. This form has leaves resembling those of the Marshwort 
(Helosciadium nodiflorum), very thick, erect stems, and small 
flowers with a pinkish tinge. It is well worthy of notice, 
differing widely in appearance from the typical form ; so much so 
indeed, that in the neighbourhood of Buckingham, where it is 
abundant, it is called ‘‘ Brooklime,” and considered as quite dis- 
tinct from the ordinary Water-cress. 
The Barberry (Berberis vulgaris) has been observed near 
Fingest by Mr. Daniel Avery, who also found the Columbine 
(Aquilegia vulgaris) in a wood near Lane End, in flower; it 
seldom blossoms with us in a wild state. The Great Dodder 
( Cuscuta ewropea) was found by Miss Chandler growing plentifully 
on nettles near Hughenden Park. The Mezereon (Daphne 
Mezereum) was again observed in its former localities: the Bog 
Pimpernel (Anagallis tenella) and Lady’s Tresses (Spiranthes 
autumnalis) on Lane End Common. The beautiful Snowflake 
(Leucojum estivum) I had the pleasure of gathering, on May 8th, 
from the meadows by the Thames near Harleyford, in company 
with the Large Bitter-cress (Cardamine amara); this locality, 
however, is beyond our district. The Stinking Iris (Jris 
Jetidissima) I found in a small wood near Flackwell Heath ; it is 
very remarkable that it has not been observed in any wood in 
our own immediate neighbourhood, as the locality would appear 
conducive to its growth. The Good King Henry (Chenopodium 
Bonus-Henricus) was gathered, late in the season, at Forty Green, 
near Penn; it has only one other station in the county. 
Thus, as each year comes round, it introduces fresh objects to 
our notice: season by season, the naturalist finds something to 
engage his attention. Natural History is the one study which 
we can never exhaust, for the more we advance in our knowledge, 
_ the more plainly we see how much we have yet to learn.
