CAREX PSEUDO-PARADOXA 17 



Stem thinner and more delicate. Inflorescence not paniculate, even 

 the lower spikelets short and upright. Eare. C. panictdata var. 

 pseicdo-paradoxa A. & G. Syn. ii, 2, 46 (1902). C. Pseucloparacloxa

 C. paradoxa b. pseudoparadoxa Eichter PL Eur. i, 149 (1890). C. 

 IMuiculata var. simplex Uechtritz Herb." 



As regards the variety tenuior mentioned above, the reference 

 should read " Sond. ex Grantzow " ; of this I have been unable to 

 see a type specimen, but in Herb. Brit. Mus. is an example labelled 

 " f . temiior Grantzow " (A. v. Hayek, Fl. Stir, exsicc. 15 lief., 725, 

 1909), which seems identical with Gibson's plant. 



From the above it would appear that the plant may be separated 

 from C. paniculata as a variety by the following characters : 



Var. PSEUDO-PARADOXA (S. Gibs.). Whole plant more delicate 

 and graceful, not forming immense tussocks ; stems 3|-5^ deem, 

 high; leaves narrower, 2^-3| mm. broad ; inflorescence simulating 

 that of C. teretiuscula or with short erect branches as in 

 G. paradoxa. 



Gibson {op. cit. 1044) mentions a difference in the perigynium, 

 but I have not been able to confirm this. 



EAST WILTSHIEE MOSSES. 

 By C. p. Hurst. 



Not very much is known of the bryology of Wiltshire, the 

 Tnosses of North Wiltshire having been especially neglected. Mr. 

 H. N. Dixon has published a very interesting paper, entitled 

 " The Moss Flora of the Marlborough Grey wethers " {v. The 

 Wiltshire Archaeological and Natural History Magazine, vol. 

 XXXV, p. 587-590, December, 1908), and Mr. A. B. Jackson has 

 contributed Eecords for North Wiltshire to the Census Catalogue 

 of British Mosses (1907), while Miss E. Armitage and Mr. J. 

 Saunders have supplied records for South Wiltshire to that publi- 

 cation. 



The following mosses have been collected mostly in Saver- 

 nake Forest, Marlborough, and around the border village of Great 

 Bedwyn, which lies to the south-east of Savernake Forest and 

 not very far from the county boundary between Wiltshire and 

 Berkshire. The Kennet and Avon Canal dividing Wiltshire into 

 the vice-counties of North Wiltshire (7) and South Wiltshire (8) 

 passes through Great Bedwyn. The soil is chalk, with Eocene 

 outliers consisting of Eeading Sands capped with London Clay ; 

 a bryological drawback is the absence of rocks, sarsen stones 

 being rare. The occurrence of Grimmia trichophylla, Grimmia 

 suhsquarrosa, Hediuigia ciliata, and Ortlwtrichum rupestre on 

 sarsen stones near Aldbourne is interesting ; these stones are
