SHORT NOTES. 57 



to both, the former the more common in Tiree, the latter much the 

 commoner in Coll, occurring locally in abundance, and sometimes 

 as a caulescent form. D. anglica Huds. was not seen. Among the 

 Tiree plants should have been mentioned Plantcujn Coroiwptis, var. 

 mantima Gren. & Godr. It is a distinct-looking plant with broad, 

 thick, Heshy leaves when growing. Mr. Arthur Bennett, on naming 

 it as above, remarked, " it is certainly the var. marithna Gren. & 

 Godr., Flore de la France, vol. ii." It has not been previously 

 recorded from Britain, I believe. 



There were 357 species and varieties noticed on the two islands; 

 of this number there were upwards of sixty limited in each case to 

 one island, but another visit will of coarse alter this relationship 

 considerably. The number of species not previously recorded for 

 the vice-county was about forty, as I am informed by Mr. Bennett, 

 to whom I am greatly indebted for having examined and named 

 several bundles of plauts sent to him in the fresh state from both 

 islands. 



The Characece gathered were Cliara fragilis Desv., and var. 

 delicatula Braun, C. aspera Willd., and var. siihinermis Kuetz., also 

 a form approaching var. curta Braun, C. contraiia Kuetz., C. hispida 

 L., C. vulgaris L., and var. papillata Wallr., Nitella translucens 

 Agardh, N. opnca Agardh, all of which are, I believe, new to the 

 vice-county, with the exception of 0. fragilis. I am indebted to 

 the Messrs. Groves for having kindly named most of the above. 



So far, it seems as if the flora of Tiree, especially, resembled 

 more that of the Outer than that of the Inner Hebrides, at least 

 of those islands from Mull to Skye. Tiree and Coll have in the 

 main the same geological formation (Lewisian gneiss) as the 

 Outer Hebrides, while the islands from Mull to Skye aie mainly 

 composed of tertiary basalts, and have their floras corresponding 

 to one another closely ; but further searching is necessary before 

 an accurate estimate can be made of the relative effects of geo- 

 logical formation and of latitude. 



Since the above was written, the following additional Characece 

 from Tiree and Coll have been kindly named for me by Messrs. 

 Groves : — Cliara fragilis, var. delicatula Braun ; C. aspera, var. 

 isubiitermis Kuetz. ; also a form approaching var. curta Braun ; C. 

 cuntraria Kuetz. ; C. hii:pida L. ; C. vulgaris, var. papillata Wallr. 



SHORT NOTES. 



New Fungal Disease of Kape. — A few weeks ago I was sent 

 some leaves of rape, extensively diseased, from near Tullamore, 

 King's Co. These leaves were covered with pallid spots, about a 

 third of an inch in diameter, but usually becoming confluent, and 

 so forming much larger patches. In these the parasite had almost 

 entirely destroyed the chlorophyll, rendering the part nearly or quite 

 transparent. Microscopic examination revealed numerous long 

 slender conidia, at once suggesting Fumularia ; but as none of the
