178 THE VICTORIAN NATURALIST. 



australis (Hook.) occurs. This is also a submerged plant, rather 

 thicker and wider in the leaves than Zostera, and is frequently 

 washed on the shore after storms. The aquatic plants to which 

 I have referred are not so attractive as many flowering plants, 

 and therefore on that account they do not appear to have been so 

 carefully examined, nor their distribution in these colonies so 

 correctly recorded, as more showy species. For this reason I 

 have taken the liberty of calling attention to them. 



LICHENS FROM THE VICTORIAN ALPS. 



With Description of New Lichen, and List of Lichens New 

 TO Victoria. 

 By Rev. F. R. M. Wilson. 

 ( Read before Field Naturalists^ Club of Victoria, loth Afarch, 1890.) 

 As one of the Alpine excursionists of the Australasian Association for 

 the Advancement of Science, I report on the lichens found during 

 the excursion, 15th to i8th January, 1890. 



At Bright I collected 4 Calicia, i Cladi/m, i Usnea, 3 Farmeliee, 

 1 7/ieloscliistes, i Lecanora, i Fertussaria, i Fletej'othecium, i Lecidea, 

 I Buellia, and i Verrucaria, all of them more or less frequent in 

 the colony. In the Ovens valley, where we halted for a few 

 minutes on our way to Harrietville, I found i Usnea, i Nephtomium, 

 several Parmelice, and several Lecidece, all common species. 



When we arrived at Mount Bernard we had an hour or two of 

 daylight, which I spent in examining the itw lichens around 

 Boustead's. And in the morning, rising early, I walked over to 

 the Diamentina Springs, and half-way back to Boustead's. These 

 were the only opportunities for collecting ; and, as the mountains 

 are sandstone and very dry, and have been frequently fired, there 

 are comparatively few lichens to collect. Here and there, how- 

 ever, chiefly on the south and south-west side of the rocks at Mount 

 Blowhard, were found specimens, but neither so numerous nor so 

 vigorous as I had expected to find at 6,000 feet above sea level. 



Professor Hutton, of Christchurch, New Zealand, kindly assisted 

 me by collecting such lichens as he found. One of them was a 

 fruited specimen of Umblicaria polyphylla, f anthracina, which I 

 was not fortunate enough to find in fruit myself. Mr. C. French, 

 jun., also, by kind instruction of Baron von Mueller, collected for 

 me ; and among other plants he gave me a Lecanora which I did 

 not find myself, and which is new to me. Possibly it may be new 

 to science. 



By subsequent examination I have made out the appended Hst 

 of lichens collected on Mount Hotham. The alpine or sub- 

 alpine species are marked with an asterisk. 



The Feltige?a polydactyla was found in the crevices of rocks 

 with a southern aspect. Its crispate thallus with recurved
