Salicornia (Plant grey green). Amongst mud and stones, 



constantly submerged, Hayling Island, South Hants, v.-c. 11, Aug. 

 1912. — J. Comber. " A small state of >S'. europaea, L., forma striata, 

 Moss." — E. S. Marshall. 



Salicornia 1 (Plant bright green, turning red). On grass, sel- 

 dom submerged, mud flats, Walney Island, N. Lancashire, v.-c. 69, 

 Sep. 1912. — J. Comber. "Small form of S. europaea,!^." — C. E. 

 Moss. ">S'. europaea, L., iormn patula, Moss, I think. Dr Moss tells 

 me that he has occasionally seen this species turning red late in the 

 season ; usually it becomes yellowish." — E. S. Marshall. 



Salicornia europaea, L., forma stricta, Moss. Mud flats, constantly 

 submerged, Hayling Island, South Hants., v.-c. 11, Aug. 1912. — J. 

 Comber. " Of the two specimens before me one is S. europaea x 

 ramosissima ; the other may be this hybrid ; but if so it is nearer >S'. 

 europaea. This hybrid is rather common on the sliores of Hayling 

 Island." — C. E. Moss. "Yes, it abounds there." — E. S. Marshall. 



Salicornia europaea, L., forma s^ricto. Moss. (Plant bright green). 

 Mud flats, constantly submerged, Walney Island, North Lancashire, 

 V. c. 69, Sep. 1912.— J. Comber. "Yes."— C. E. Moss. 



Salicornia prostrata, Pall. On mud, seldom submerged, Walney 

 Island, N. Lancashire, v.-c. 69, Sep. 1912. — J. Comber. ">S'. europaea, 

 L., iormsi patula." — C. E. Moss. 



Salicornia disarticulata. Moss. [Ref. No. 957.] Brightlingsea 

 Creek, Essex N., v.-c. 19, Sep. 28, 1912.— C. E. Britton. "The 

 single specimen before me shows traces of S. gracillima. S. disarticu- 

 lata hybridises rarely. The other specimens I have seen which suggest 

 hybridisation are some on a sheet in Herbarium Linton. Mr Linton's 

 specimens exactly match this one of Mr Britton's. Some of the other 

 herbaceous species of Salicornia hybridise very freely." — C. E. Moss. 

 " Excellent specimens, and very typical." — E. S. Marshall. 



Polygonum lapathifolium x Persicaria. Ditch by Radyr Church, 

 v.-c. 41, Aug. 1912. Spike greenish pink; glands of perianth few; 

 perianth veins sometimes well marked ; lower ocreae more or less 

 fringed. Intermediate and probably the hybrid. The plants sent 

 are all of one stage, but others occurred of intermediate character. — 

 H. J. RiDDELSDELL. " This is a nearly eglandular state of P. lapathi- 

 folium and but for the well developed seeds it might have been 

 regarded as a cross between that and P. Persicaria. Despite the 

 strongly ciliate ochreae and the paucity of glands on the perianth, 

 I think it must go to P. lapathifolium on account of the seeds, which
