410 CALENDAR, 1820. 



The Lychis dioica is abundant by the road sides in Surrey, 

 and the Germander Speedwell every where blooms on the 

 braes. 



19th. Carduus marianus (sine lacteis siriis) and Hera- 

 cleum sphondylium, now in full flower. 



20th. Gladiolus communis the Corn Flag in full flower. 



21st. Weather calm and fair. 



Lychnis chalcedonica just coming into flower. Poppies 

 begin to be common ; though those sown in the spring are as 

 yet small, and only just begin to rise up in the stalk. Sweet 

 Williams and Pinks are also in bloom. 



Oenanthe crocata in flower by the road sides. 



22d. I procured and sowed some of the seeds of the Ma\v 

 Poppy, which are of a bluish grey colour. I take this to be 

 the wild P. somniferum. 



23d. I found Papaver Rhaeas, P. dubium, P. Argemone, 

 and P. hybridum, all flowering near Brighton. I likewise saw 

 the small variety of P. Argemone, which is by some persons 

 mistaken for a new species, and called Papaver maritimnn 

 In riding through Chaley, from Brighton to Hartfield, I ob- 

 served that no Poppies were found nearer than Newark, and 

 there were only a few there, perhaps one or two by accident. 

 I should consider the tract of country devoid of Poppies (of 

 which tract we may consider Crawbrough Beacon as in the 

 centre), as extending to within five miles of the sea. When 

 on the South Down Hills again, they are seen among the corn 

 and other sown fields, though by no means so numerously as 

 in parts of Surrey and Hampshire.* 



* A work exclusively on the Range and Distribution of the Habitats of 

 Plants, made out to correspond with maps of the strata, would be very 

 interesting ; and if such a work were in the contemplation of any able 

 person, I should be happy to contribute several observations which I have 

 made on this subject.
