Summer rambles on the Orme'shead, 

 Llandudno. 

 No. I. 

 Tliis headland is formed of the 

 carboniferous limestone, which here 

 crops out from a chain of submer- 

 ged rock, that trends from the -north- 

 ern coast of Flint, in a westerly di- 

 rection, towards Puffin Island, and 

 the Isle of Anglesey. The Flora 

 will consequently be found to contain 

 such plants as delight in the moun- 

 tain limestone ; some being of con- 

 siderable rarity, and strictly local 

 distribution. 



We will begin with the Notting- 

 ham Catchfly, Sllene mdans, one of 

 the Caryophyllacese, that abounds on 

 the upper ledges of the rock, and 

 may be readily recognised by its 

 white drooping flowers, which are 

 sweetest in the evening. The cap- 

 sules of tliis plant feed the rare 

 Dlanthxecia cdhimacida, which has 

 not been taken in Britain since 18 IG. 

 It is possible it may yet turn up at 

 Llandudno. A case-bearer, Coleo- 

 X>liora leuco2)ennella, feeds also on 

 the seeds of Silene nutans on the 

 Contment, as was mentioned by Mr. 

 Stainton, inr a paper read before tho
