stained-leaved Hieracium ; but I possess no specimen of it, nor do I 

 clearly understand what is intended under the name of rigidum. 

 Thus, we have varieties " maculatum " of H. murorum, Lawsoni, pul- 

 monarium, sylvaticum, rigidum, and, probably, nigrescens — if this 

 latter is not the same as pulrnonarium. In Decandolle's Prodromus, 

 there is only a single "maculatum" recognized byname; and that 

 one is placed as a variety under H. murorum. — Hewett C. Watson ;

529. Note on the discovery of Leersia oryzoides in Sussex. You 

 may, if you please, insert in the next number of ' The Phytologist,' a 

 notice of the discovery of Leersia oryzoides as a British plant. I 

 have found it in three places in the Heniield level, growdng along the 

 edges of the marsh-ditches. I first observed it on the 24th of Sep- 

 tember last.— W. Borrer ; Henjield, October 8, 1844. 



530. Note on Jimcus diffusus f A plant which I had supposed 

 might be Juncus diffusus, grows plentifully within the sand-hills, on 

 the east side of Huntston, between Lynn and Wells, Norfolk. It 

 forms spreading patches of large size, mixing with J. maritimus. I 

 thinlc the same plant grows also near the river, above Lynn, but what 

 I took for it there was much injured by cattle. Juncus effusus is no- 

 ticed as Biitish, in Babington's Manual, "on the authority of W. Son- 

 der, of Hamburgh, who possesses Scottish specimens." It may be 

 distinguished from J. glaucus by having solid pith ; that of J. glaucus 

 being cellular : it is also a greener plant, and has mucronate fruit. 

 This notice may perhaps lead to further enquiry. — James Backhouse; 

 York, Uth qflOih Month, 1844. 



531. Note on Cuscuta europcea, 8fc. I lately noticed Statice spa- 

 thulata, growing in company with S. Limonium and S. reticulata, near 

 Wells, in the opening opposite Holkham ; and Cuscuta europsea, on 

 nettles, in the Bulwark-road, Earith, Huntingdonshire. C. europaea 

 is of frequent occurrence in the adjacent parts of Cambridgeshire, 

 where it is called " scald ; " it may be presumed, on account of the 

 scalded appearance which it gives to the bean- crops, to which it is 

 often injurious. Burning the bean-chaff, and keeping the hedges free 

 from nettles, have removed this pest to the farmer from some places 

 where it formerly abounded. — Id. 



532. Note on Carex teretiuscula. Your correspondent Mr, Lux- 

 ford (Phytol. 1021) has appealed to me for further information as to 

 the Carex found near Halnaby, and which I conceived at the time 

 might be a small variety of C. paniculata, A further examination has
