i88o] Rare Plants in Anglesea. 277 



please make your arrangements to cross by the mail on Monday evening, 

 and sleep at the New Hotel. There is a train arriving at Holyhead at 

 10 A.M. (on Tuesday), by which I suppose we shall arrive, hoping to 

 meet you on the platform. There will be Babington and myself, and 

 I hope a good local botanist from Bangor ; so that we shall have a nice 

 day, and I hope you can come. 



The " good local botanist from Bangor" was Mr. J. E. 

 Griffith, author (at a later date) of the "Flora of Anglesea 

 and Carnarvon," who on the 3ist accompanied them to 

 Holyhead. Here were gathered Helianthemum breweri* 

 and another local plant of even greater interest, the 

 " Cineraria" of Holyhead Mountain, previously supposed 

 identical with the Cineraria (or Senecio) campestris of the 

 English Chalk Downs, but not believed to have been 

 gathered or seen in situ for more than half a century, 

 and whose recent re-discovery here by Mr. Griffith soon 

 occasioned great differences of opinion among botanists 

 as to its rightful identity and rank. 



From Holyhead the party proceeded to the scene of 

 a still more interesting re-discovery due to Mr. Griffith, 

 and made an expedition to Penrhos-Lligwy. Here, in 

 a little stream, held long grown a plant not known to 

 inhabit another spot in the world the celebrated " Pota- 

 mogeton lanceolatus of Smith." Owing to the out-of-the- 

 way and "almost inaccessible " nature of the locality, this 

 pond-weed had not, Professor Babington thought, been 

 gathered by any botanist between 1832 and 1879. More- 

 over, it held rank as the only species of plant confined 

 strictly to Great Britain ; and, as a further claim to dis- 

 tinction, no one had ever discovered its fruit. 



So, hearing that Potamogeton lanceolatus had lately 

 been found by Mr. Griffith to be plentiful in its old locality 

 which a new railway also had rendered more approachable, 

 the botanists gladly resolved on going thither. Rather 

 curiously, it so happened that during the same month 

 (August 4th) Mr. Arthur Bennett found the same species 

 in the Fens of Cambridgeshire, so that already Penrhos- 

 Lligwy had been shorn of some of its eminence; but in 



* A variety of H. guttatum. The Inish-bofin plant is now referred to the 

 same form.
