86 FURTHER NOTES ON THE KERRY FLORA. 



Among other critical plants gathered were Thymus Chamcedrys 

 and Sparganium neglectum ; neither of these segregates appear to 

 have been recorded from Ireland before. Pumunculm Godronii, 

 TnfoUum fiUforme, Rupjna spiralis, Eriophorum latifolium, Equisetum 

 trachyodon, and E. hyemaJe were also gathered, with several new 

 stations for Rhynchospora fiisca and Isoetes echinospora. 



Mr. Arthur Bennett has very kindly looked through my Potamo- 

 getons; these include a very large form of P. ru/escens, queried 

 for var. maxiimis (Rohlz), P. nitens, with its var. citrvifolius, P. 

 Zizii, and others, on which he sent me some interesting notes, 

 especially on Syme's var. linearis of P. polyyonifolius. This plant 

 in its most extreme form produces only long capillary leaves, and 

 passes from this almost imperceptibly into P. natans, with floating 

 leaves plicate at the base. Both Mr. Bennett and Mr. Fryer say 

 that this variety must be referred to P. natans, instead of P. poly- 

 yonifolius. Dr. Tisehus, in Sweden, and Eev. T. Morong, in 

 America, agreed on this point with Mr. Bennett when he sent them 

 specimens three or four years ago. P. linearis seems a barren 

 state, and herein lies all the difficulty with this and another plant 

 which grew, quite submerged, in the midst of dense masses of 

 ''linearis,'' and is very puzzling. I marked the labels " P. j^oly- 

 yonifolius, submerged form." Mr. Fryer, who saw the plant, says, 

 " I should so name it .... Is not this form Syme's pseudo-flidtans, 

 if that name does not represent fluitans / It seems nearer to the 

 American P. Lonchites than any I have seen before from Ireland." 

 Mr. Bennett says that, with only immature specimens before him, 

 a satisfactory name is not possible. Though gathered in the middle 

 of August, there was no sign of its flowering. 



Another puzzling plant is a long, straggling, dark-leaved form 

 growing abundantly in the Eiver Laune. Mr. Fryer says it is 

 impossible to see this plant without thinking of Syme's P. Lonchites, 

 though he cannot make it agree with the Boyne Lonchites. He con- 

 siders it one of the doubtful forms of heterophylliis with amplexicaul 

 leaves. Mr. Bennett has little doubt as to its being a form of P. 

 Zizii. 1 shall hope to see more of these plants next season. 



Two interesting Kerry records which I failed to verify are 

 Sisyrinchiwn anyustifolium and Lathyrus maritimus. The Sisynn- 

 chium had been gathered near Kilcolman Abbey, Milltown, about 

 four miles east of Killorglin. Through the kindness of Lady 

 Godfrey, I was shown the spot where she had found it in 1887, and 

 again several years before that. The locality is a coarse, boggy 

 pasture, about a mile from the Abbey, and though we looked long 

 and closely in the restricted portion of the field it had occurred in, 

 our search failed to discover any trace of the plant. Very few 

 plants were noted in 1887, but whether the Sisyrinchium has become 

 extinct, or is only dormant, the next year or two will probably show. 

 I have no doubt that this is the same place where the Sisyrinchium 

 was gathered by my friend Mr. A. G. More, as recorded in Journ. 

 Bot. 1882, p. 8. LatJiyrus maritimus appears first in Smith's list of 

 104: Kerry rarities as occurring on the south point of Inch Island in 

 considerable quantities ; this would be about 1750. It was gathered
