recorded in Mr. Wliite's Flora as IF. amplexicaiile growing on a wall 

 in Richmond Hill, Clifton. This I found to be //. pidwoiiarioiiJes. 

 1 also noticed recently, among the latest additions in Hb. Mus. Brit., 

 a sheet of II. piflmonarioides sent to the Botanical Exchange Club 

 bv Mr. C. Bailey in 1897 from a ^vall near Saltburn, Yorkshire, 

 under the name of H. amplexicaule, and passed as such. The Cleish 

 Castle, Kinross, and the Oxford specimens that I have seen are true 

 FI. amplexicaiile L. When in Northern France last summer, visit- 

 ino; the grave of my eldest son near Arras, I observed II. palmona- 

 rioides growing on the ruins of the cathedral there and on the walls 

 of other buildings in the town destroyed in the War. The natura- 

 lisation on ruins and old walls in Britain and Northern France of 

 these two similar but perfectly distinct hawkweeds, both natives of 

 t'le Alps, is a somewhat curious fact that does not seem to admit 

 of a ready explanation. — H. W. Pugslet. 



Ceuastium hibsutum Tenore. The observations of Mr. F. N. 

 Williams on this species (Journ. Bot. 1921, 352) are rather behind 

 the times. He quotes from Nyman some remarks of mine of the 

 3^car 1884, but it seems to have escaped him that I have dealt fully 

 Avith the subject in Bullettino della Societd Botanica Italiana for 

 1912, p. 109, and have distributed in Fiori and Beguinot's Flora 

 lialica Exsiccata, nos. 1653 and 1654, specimens of the t^'pical 

 glandular form and of ray var. eglandulosiim. Till a few months 

 ago the only known stations for the species were the mountain range 

 that separates the gulfs of Naples and Salerno, where it is exceed- 

 ingly plentiful, to the exclusion of all forms of C. arvense L. or of 

 0. ColumiKB Ten. ((7. tomentosum auct.), and the slopes of Vesuvius 

 and Monte Busambra in Sicily. In July 1921 1 found it in abundance 

 on Monte Mai, due north of Salerno ; this is the first record for the 

 ranges east of the railway-line from Nocera to Salerno. Farther 

 east, north and south, it gives way to C. Columnce^ of which the 

 locus classicus is Monte Vergine. Specimens from other districts 

 are sometimes wrongly labelled C. hirsiifum : these are usually 

 C. arvense var. etruscum mihi, or C. Scara?ii Ten., which is also 

 a form of the arvense group. Similar false records — e. q. La Mongiana 

 in Calabria — occur in Italian Floras. — C. C. Lacaita.
