water condensing-dam of a cotton-mill below Halifax) appears 

 not to have been made in time to be included in the London 

 Catalogue. The cotton-brought waif is welcome to Yorkshire 

 waterways, along which it will doubtless spread, if not 

 anacharistically. Eriophoriini a ngiisti folium, has a new var.^ 

 triquetrum, Fr. added ; but the genus Carex is not greatly 

 altered. C. ligerica, Gay is deleted as dubious, a new var. 

 remota, Marss (1770, b.) taking the place of i66i,b. in the 9th 

 Edn. The Druce List, however, includes it with his ' angle- 

 bracket ' sign of doubtful-ascription affixed. The ' new names ' 

 are C. chordorhiza, L. fil — his first appearance in the British 

 arena apparently. C. spiculosa, Fr. var. hehridensis, A. Bennett, 

 represents a species with only one station as yet known. C. 

 frigida of the 9th Edn. drops out : Sadler's plant so determined 

 for a while being considered by Linton to be alp-modified 

 binervis and so dubbed ' Sadleri ' (1819, b.). Carex infiata x 

 riparia (Beckmanniana , Figg.) is given in Oxford List, sith 2564, 

 but is wanting in L. C. loth. Among the Gramineae are a dozen 

 Additions, viz : Agrostis verticillata, Vill (Sarnian, and ' Wool 

 Alien), A. scahra, Willd. (Oxford List) ; Phalaris minor, Retz. ; 

 Milium vernale, Bieb. {scabrum, Merl.), Sarnian too ; Koeleria 

 vallesiana, Asch., and K. brita^tnica, Domin (O. L.) ; Glyceria 

 festuciformis, Heyn. (N.E. L-ish littoral, and ballast alien ! ) ; 

 Festuca unilateralis [F. ciliata, Danthonii maritima, L.), which 

 assurged so strangely by roadsides on arid Cornbrash about 

 Carlby in S. Lincoln a few years back ; Poa cenisia, All. b. 

 flexuosa, Wahl, queried ' i ' vice-county as if incerte ; Glyceria 

 Foucaudii, Hackel, perhaps another species-in-making, or a 

 split off Ct. maritima ; like Festuca dumetorum, L. (given for 

 Skegness, Line, Hackel in litt, Oxford List, No. 2786) is off 

 Festuca rubra, but which the loth Edn. omits to place at all ; 

 Agropyron cristatum, Gaertn. (wool-alien, Yorks ! ) in the Druce 

 Catalogue onlv ; and, in like case, the Loliums, L. siculum. 

 Pari and L. rigidum, Gaud., not so very infrequent along with 

 Leptiirus incurvus, L. (also wanting in loth Ed. list), where 

 fleeces have been lime-treated, and the scourings cast out : 

 all three are strange-looking livid and rigid-stalked grasses. 

 The only really new Fern is the No. 2026, London Catalogue, 

 not in Oxford List — Botrychium lanceolatum, Angstrom, about 

 which T have no information. 



What more that m.ay be of use to Yorkshire field botanists ? 

 Three inclusions of Mr. Druce's have local applications — five,
