GLOUCESTEESHIEE NOTES 351 



always confined to tlie actual coast : I have knoAvn it flourisli in 

 Glamorgan on rocks 2 or 3 miles inland. 



Thlaspl perfoliatum L. occiu-s in such abundance in districts 1 

 (5 miles from Campden), 6, and particularly 7, that it may be 

 regarded as one of the characteristic Cotteswold plants. It happily 

 occurs usually in such out of the way places, and on such stony and 

 " useless " soil, that it is most unlikely to disap])ear. In some neio-h- 

 bourhoods, it can be found on almost every suitable-looking piece of 

 bare soil. On one occasion, I looked over a low wall into some Avet 

 ground for a chance of bog plants, and was surprised to find the 

 reverse side of the wall for some distance covered with a luxm*iant 

 growth of T. perfoliatum 4 to 6 inches high. 



CaJclJe maritima Scop. 2 h. Sharpness. 4. Sand near Beachley, 

 1863, *SV. Brodi/. 5. 1 specimen on the Bristol side of the Severn, 

 191Q, J^. JL Daij^ Evidenth' in the same case as Glaucium and 

 Eryngium maritimum : appearing rarely, and disappearing for many 

 years. All three species may possibly appear as the result of tidal 

 action. 



Sfellnria Rolostea L. A form has been sent to me by J. W. 

 Haines from Birdlip with petals shortened and more deeply cleft than 

 usual. The sepals are also sometimes shortly ciliate in their lower 

 half. I suppose this is just a step away i^-om t^'pe towards the 

 apetalous form. 



Geraniinii columbinum L. is a frequent and characteristic plant of 

 rough stony upland pastures on the Cotteswold Hills : more at home 

 there than any other species of this genus. 



Biihiis Godroni Lee. & Lam. var. clivicoJa Ley appears to be a 

 common bramble of the neighbourhood of Birdlip, usually occurring 

 at 800 to 900 feet of elevation. Too man}^ of the Buhus records for 

 v.c. 38 rest on the occurrence of a single bush or at best a single 

 clump : but much work remains to be done in the genus, as far as 

 E. Gloster is concerned. 



Pyrus scandica Aschers. This species (I believe) occurs in 

 quantity with P. Aria in a grove near the top of Haresfield Hill 

 v.c. 38. As JBetuIa is there too, both are probably introduced in the 

 locality. 



Chrysospleniu7n alternifolium L. is a species characteristic of 

 ditches and small streams in deep shade all over the Cotteswolds. 

 It is, 1 believe, even more frequent than G. oppositifolium. 



Carum Btilhocasfanum Koch has of late years been found by 

 several botanists in cornfields near Cheltenham. It is an introduced 

 plant in this locality. 



Senecio integrifolhis Clairv. has been found at different times, 

 usually in very small quantity, in three or four spots on the Cottes- 

 wold Hills : on one occasion T saw it in great quantity and luxuriance. 

 But sheep nibble it and it does not get much chance. It is not a 

 characteristic plant of the Cotteswolds, and is quite uncertain in its 

 appeai-ance. A few plants were seen on downs near Northleach 

 last year. 



Cenfaurea Scahiosa L. In August I found a clumji of this 

 species between Cheltenham and Birdlip, with the heads of fiowers
