From a few gatherings made from time to time on Austwick 

 Moss, we have noted the following species, none of which have 

 been previously recorded for this locality ; some are new to 

 Yorkshire, and some new to West Yorkshire. We have by no 

 means ascertained all the species occurring on the moss, the 

 list given representing the species noticed in the gather- 

 ings we examined. The moss is yet in some parts primitive, 

 and in wet seasons one has to be careful where one treads.* 



Before enumerating the algae, it will be as well to portray 

 the nature of the ground, giving a list of some of the larger 

 plants, some of which are immediate associates of the Alg?e, 

 and at the same time it ^^•ill be more interesting to the general 

 reader. The moss has been partially drained, yet a large num- 

 ber of plants which always gladden the eye of a field-botanist, 

 still linger in plenty on the moss, where it is no difficult matter 

 even now, to find wet places. Among these are : — Viola 

 pahistris, Comarum palustre, Drosera rotimdifolia, Taraxacum 

 officinale var. palustre, Andromeda poli folia, Vaccinium Oxy- 

 coccos, V. Vitis-IdcBa, Primula farinosa, Pingiiicula vulgaris, 

 Myosotis scorpioides, Pedicidaris palustris, Veronica scutellata, 

 Salix repens, S. aiirita, Myrica Gale, Triglochin palustre, Hahen- 

 aria hifolia, Orchis incarnata, fine forms of 0. maculata, Narthe- 

 ciiim ossifragum, Sckoenus nigricans, Eriophorum latifolium, 

 Carex vesicaria (with about twenty other species on the moss 

 and in its neighbourhood), Blysmus compressus, Selaginella 

 selaginoides. 



On the way to the moss from Clapham, the following among 

 others can be seen : — Nymphcea lutea. Geranium sylvaticum, 

 Poterium sanguisorba, Anagallis tenella, Campanula latifolia, 

 Potamogeton crispiis, P. densns, Scirpus lacustris, Allium Score- 

 doprasum, Cystopteris fragilis, Asplenium Trichomanes, A. Ruta- 

 muraria.

* One of U3 crosses this rich moss annually with a number of ladies' 

 who have to bs carefully piloted; the gentlemen are usually left to seek 

 their own dry path.
