i88 ANNALS OF SCOTTISH NATURAL HISTORY 



these butterflies captured on other occasions by sundews. One 

 might well suppose they are too large to fall easy victims. On the 

 occasion referred to, I saw nothing that could explain the large 

 number captured ; nor were the insects at all more numerous than 

 usual on the moor, either at the spot or elsewhere. ID. 



New Scottish Hawkweeds. In a paper on "British Hawk- 

 weeds " by Messrs. E. F. and W. R. Linton, of which two instalments 

 have appeared in the Journal of Botany (May and June), several 

 new "species" and "varieties" are named and described, and 

 numerous additions are made to previous county records. Almost 

 all the plants noticed in the paper are from Scotland. The new 

 forms are : H. graniticohun, n. sp., from Corrie Etchachan, under 

 Ben Muic Dhui ; If. dorense, n. sp., fairly abundant in Clova from 500 

 to 2000 feet above the sea, also in Canness and at Cairnwell ; 

 If. bifid UM, Kit., var. nov. siiutatum, W. R. Linton, near the fall of 

 Unich Water, above Loch Lee in Forfarshire ; H. Pictorum, Linton, 

 var. nov. dasythrix, from Corrie Ardran, in Mid-Perth ; H. Boswellii, 

 n. sp., from near Kirkwall in Orkney, the Strath of Dunbeath in 

 Caithness, several localities in Skye, and Meall-nan-Tarmachan and 

 near Killin in Mid-Perth ; H. ccesiuin, Fr., var. nov. petrocharis, from 

 the Breadalbane Hills ; H. euprepes, Hanbury, var. nov. glabratum, 

 from Clova district, and from three localities in Mid-Perth; H. 

 ste/wphyes, n. sp., from Bettyhill in Sutherland, from Mid-Perth, from 

 Dumbarton, and from near Moffat. 



Experimental researches on the Life-history of Uredinese. 



Dr. Plowright has published in " Grevillea " (June) the results of 

 experiments on certain forms of heteroecismal fungi, of some of 

 which a brief account has already appeared in the " Gardener's 

 Chronicle." He finds that ^-Ecidiitm Periclymeni, Schum., on honey- 

 suckle produces a Puccinia on Festuca ovina and on F. duriuscula, 

 but not on other grasses, and that, conversely, the spores of this 

 Puccinia produce only sEcidiuin Periclymeni. He describes the 

 cycle under the name Puccinia Festuctz. He has worked out similar 

 relations between sEcidium Aqiiilegice, Pers., and a Puccinia on 

 Agrostis alba, and A. vulgaris, and describes the cycle under the 

 name Puccinia Agrostidis. 



He has established a similar cycle between Uromyces lineolatus, 

 Desmaz., on Scirpus maritimus and sEcidiitm Glands on Glaux 

 maritiina. 



Uredineae in Scotland. In reference to Dr. Plowright's results 

 as stated in the above paragraph, it may be of interest to mention 

 that sEcidium Periclymeni is common in many localities in Scotland, 

 and that sEc. Aquilegice has been found near Ballater. I have also 

 examples of Festuca ovina and of Agrostis alba, both bearing uredo 

 and teleutospores of Puccinia, found by myself in Aberdeenshire,
