BOTANY. 



Rubia peregrina L. and Tragopogon porrifolius L. on 



Lambay. 



Behind the cottages at the harbour on 27th June I noted a colony of 

 Salsify {Tragopogon porrifolius) which is possibly of garden origin, but 

 which will probabl}^ succeed in establishing itself on Lambay, 



Although frequent on the railways about Belfast, this alien does not 

 seem to have been noted in Co. Dublin. 



The Wild Madder {Rubia peregrina) being, unlike the Salsify, a native 

 plant, there is more satisfaction in recording it also from the island, where 

 I found it growing in some quantity on the clay cliffs between Carnoon Bay 

 and Talbot's Bay. In Cybele II. this plant is stated to be very rare in 

 eastern Ireland, and it has not, I believe hitherto been recorded from any 

 station N. of Howth. That it should have escaped detection during the 

 v'arious surveys that have been made of the flora of Lambay is just one 

 more example of those curious puzzles that naturalists are constantly 

 encountering.

The Golden Samphire near Rush, Co. Dublin. 



On i6th June last, while examining the coast north of Rush with Miss 

 M. C. Knowles, we found a single fine" clump of this plant. Inula crith- 

 moides, on the cliffs in the first bay north of Rush harbour. 



It does not appear hitherto to have been observed in or recorded from 

 Colgan's division 2 of Co. Dublin. Moreover, this station is a little to the 

 north of Lambay, long known as its most northern habitat in Ireland. 

 As the sea has made considerable inroads in recent years close to where 

 the plant grows at Rush, it may be that this is the last surviving member 

 of a colony. On the other hand it may be derived from a sea-borne seed 

 from Lambay or Howth.
