NOTES SUPPI.EMEXTAL TO THE FLORA OF BKISTOL S3 



old record in Swete's Flora (1854). The station is the only one 

 known in our Gloucestershire division. 



P. Friesii E,upr. was lamented as a loss in this district through 

 the recent destruction of the old coal canal that connected Camertoii 

 and Midford with the Avon. But fortunately' the plant survives in 

 the river, where we were ignorant of its presence until Miss lio})er 

 raked out a little (not flowering) in August last. 



P. pectinatus L. var. dijff'usiLS Hagstrom. Brackish ditcli near 

 the Channel at St. George's Wharf, S. ; H. S. Thompson. Named 

 by Mr. A. Bennett. 



Zostera marina L. var. angustifolia 11. At low water in Kew- 

 stoke Bay, S. Oct. 1916; Mrs. ISioidicitli and 2Iiss Boper. 



Cladium jamalccnse Crantz. Nothing moj'e remarkable is written 

 in the Flora than the rediscovery of the Givat Fen Sedge on Burtle 

 Moor, whence it had been appai'ently lost for more tlian a centuiy. 

 That single tussock continues to flower sparingly. A much larger 

 mass is now known to exist on another part of the moors, a locality 

 reported in 1915 by Mr. J. W. Haines of Gloucester. His directions 

 guided me to the spot at a time when the swamp was dry enough for 

 measurements to he made. The main patch was found to be over forty 

 yards long by about Ave wide, and there were three small outliers at a 

 little distance. Now, assuming that our Western botanists are not 

 more dull or blind than ave. age folk, how can they and their forerunners 

 be excused for overlooking so considerable a growth as this? We 

 seem to get a satisfactory explanation in some remarks by Mr. 1*. H. 

 Yapp in The New Fhytolocjist, 19US, jx GO. He states that in the 

 great fen districts of East Anglia — where it is the "sedge" — 

 Cladium is cut and harvested for thatching about every four years, it 

 having been found that cutting at shorter jjeriods before the plant 

 again I'eaches maturity not only leads to invasion by more rapidly 

 gi'owing species, but may even result in local extermination of the 

 sedge. On the peat moors of North Somerset the coarse, rank vege- 

 tation of the swamps is habitually mown, when practicable, for use as 

 cattle-food and bedding. So we see that whenever the Cladium is 

 cut, should it be but rarely, a long interval happens before it again 

 becomes sufliciently conspicuous to attract attention. 



Scirpus paucijlorus Lightf. Bogs in Shipham Bottom, Mendiji, 

 1915! Still ])lentiful in wet sand at Berrow, 1915! Mrs. iSandwilh. 



S. Iloloscha'nus L. After years of struggle under the rudest ill- 

 treatment the solitary clump at Berrow has latterly enlarged and has 

 flowered more freely. 



Ulysnius comprcssus l*anz. Sandy field S.W. of the railway 

 station, Weston-s.-Mare, Jul\' 191(3; Lady iJavy and the Missrs 

 Cohhf. This may conHrm an old record by St. Bi'ody in Fl. IVcs/on. 

 In his day this sandy field must have been almost if not quite as 

 near to Uphill as to the then existing little town which since has so 

 greatly expanded. 



Friophorum latifolium Hoppe. Is now known to be locally 

 plentiful on the western slope of Blackdown, ISlendip. In one bog 

 near the head of Shipham Bottom, first noticed by Miss Roper, it is
