WATSON EXCHANGE CLUB REPORT, 1916-17 111 



A. Bahingtoni Woods. Ref. No. 208. Shingle at Bracling 

 Harbour, I. of Wight, v.e. 10, Sept. 8, 1916. All from one plant. 

 The inflorescence, hardened yellowish fruit and rhomboid bracteoles 

 put this to Bahingto7ii, as against the green fruit, bracteoles ovate 

 triangular, with base campanulate, and inflorescence leafy to the tip 

 of virescetis. I have specimens from Brading which match closely 

 Mr. Beebj^'s plant in Herb. Brit. Mus. certifled as virescens by Lange 

 himself. But though extreme plants of what Mr. Wilmott in Camb. 

 Brit. Flora groups under A. glahriuseula Edm. can be put with cer- 

 tainty to var. Bahingtoni, or var. vii'escens, I have found no speci- 

 men of either variety which does not bear some fruit tending in the 

 direction of the other. I should be glad if any member would send 

 me a series of specimens showing the complete range of Atriflex in 

 any locality. To be of use for critical study it is essential that speci- 

 mens should bear ripe fruit. — W. C. Barton. 



Liparis Loeselii [A.] Rich The extension of range of this 



species to Glamorgan !, and Cannarthen ! was of much interest. The 

 specimens from these counties agree with those sent me by Drs. Focke 

 and Buchenau from the Frisian Islands, where they grow associated 

 Avith Pyrola rotundifoJia and minor, Parnassia, Carex trinerins, 

 C. (Ederi and C. Goodenowii, Jitnciis africapiUus and Hierochloe 

 horealis. The history of its discovery in Carmarthenshire is as 

 follows: Mr. J. W. Barker wrote (June"' 14, 1906), "In July 1897 a 

 friend of mine, Mr. K. Browne, brought me several plants which he 

 had picked on the Burrows near Pembrey. Amongst them were two 

 plants of a little green Orchis, which were quite new to me. I found 

 to m.y surprise they were Liparis, and I mentioned it to Dr. H. 

 Lewis (who was a member of the Botanical Record Club about 1874), 

 but he scouted the idea of its being Lij^aris. On the 22nd of June, 

 1899, I walked out to the valley, where to vay delight I found 15 to 

 20 plants of it scattered about. A few years after, Mr. Browne told 

 me that the little valley liad entirely changed its appearance, the 

 shifting sand having covered all the vegetation."- On the 9th of 

 June the same year Mr. H. H. Knight again discovered the Lijjaris, 

 and sent me specimens, which agreed with Mr. Riddelsdell's from 

 Glamorgan (Sept. 7, 1905). In Carmarthenshire the plant Avas 

 associated Avith Carex glaitca, C. Goodenoicii, C arenaria, Salix 

 rejypns, Menilia Jiirsufa, etc. Mr. Riddelsdell sent me a list of 42 

 species Avith which it grew in Glamorganshire. We have noAV records 

 of its being gathered in some 29 stations in 6-8 vice-counties. In 

 Britain it seems to occur in abundance in cycles of about 20 years,, 

 gi-adually dying out until a recurrence. At p. 622 (1904) of tlie- 

 Norf. & Norw. Trans. I made the folloAving remark : " It is what 

 Avould be called a short-lived perennial ; probably the year it occurs; 

 abundantly it seeds freely, the plants die, and the seed floats about 

 until the Avater begins to nm off tlie land in May, then the seed 

 settles down and grows. It is Avell known that at times Orchis seeds- 

 take man}^ years to germinate and come to the floAvering stage. The 

 water level is high, perliaps for some years, then there comes a diy 

 season (like 1SS3-4), and the plant is exposed to view." Even in 

 1884 the ground was so Avet that one dared not stop long in one place 

 Avithout fen-boards. There is an excellent description of its groAvth
