ISNARDIA PALUSTRIS. 



I am wi'ong in saying that my father discovered Isnardia palustris for 

 the second time in England, on Petersfield Heath,; I ought to have said 

 for the third time. I had forgotten or overlooked the fact, that . Mr. 

 Goodyer discov ered it in the same locality previous to 1667.; in 1827 Mr. 

 BoiTer found it in another part of Sussex, thirty miles to the east,- in Hen- 

 field, and a few years afterwards my father had the good fortune to re-dis- 

 cover it in the very same spot, probably, where it had been known nearly 200 

 years before. I am afi'aid however that at the present time Isnardia palus- 

 tris must be ranked among the "Species Defunctce." Although plentiful for 

 some years, the repeated visits of botanists quite exterminated the plant, 

 and I am not aware that it has been gathered there for many years past. 

 The Brockenhui'st locality, mentioned in the seventh edition of the British 

 Flora, I have not visited, and do not know whether this rare plant has 

 had a better fate there than on Petersfield Heath. I will not ask you to 

 insert more of this than the mere substitution of tJiird for second, which 

 common courtesy requires. 



Next, with reference to the plants I shoidd like to receive and give in 

 exchange, I should be very glad of any of the following species : — Oxytropis 

 walensis, Vicia Orobus, Lathyrus palustris, L. maritimus, Circcea alpina, 

 Gentiana verna. Arbutus alpina, Draba aizoides, Pyrola unifiora. Campa- 

 nula rapunculoides, Scroplmlaria vernalis, Oynoglossum sylvaticum, Lloydia 

 serotiua, Utricularia intermedia. 



I can offer in exchange any of the following : — Belphinium Consolida, 

 Fumaria Vaillantii, Arabis petrcea. Astragalus alpinus, Saussurea alpina. 

 Cineraria campestris, Phytemna orbiculare, Seseli Libanotis, Azalea procum- 

 bens, Epilobium. alpinum, Isnardia palustris, Saxifraga rivularis, Veronica ■ 

 saxatilis, Veronica alpina. 



Address, — John Ba rton, Chichester, Sussex. 



On the Term Stri^ (Striated). 



There is some vacillation in the application of this term. Lindley, in 

 his Glossary, defines it thus : — " Streaks ; any sort of longitudinal lines, 

 whether arising from veins or fine streaks of colour, or long channellings." 

 According to the above, stria is a synonym of furrows, and sulcate is 

 equivalent to striate. Query, would it not be more conducive to clearness 

 if strice was restricted to streaks of colour, as its more extended meaning 

 is adequately represented by furrowed or channelled, or veined, or nerved, 

 or ridged ? 



Horse Chestnut, Native Country of. 



From 'Die Botanische Zeitung,' Feb. 20, 1857. 



In several parts of Europe, especially in the south, the Horse Chestnut 



is observed growing beyond the limits of cidtivation, though it be difficult 



to determine if it be a true native of the districts where it thus grows, in
