 plenty of evidence tliat tlie autlioi's uncorrohorated ipi^c dixif 

 on different plants must ])e accepted witli caution, and tliat in 

 the present, as in not a few otlier instancies, we liave an 

 ohviously erroneous record. AVith the commoner plants of the 

 two westernmost counties Jones Jiad a fairly intimate ac(piaiut- 

 ance, hut his knowh^dge of tlu- rarer ones was rcsti'icted to a 

 degree. Martyn's record winy ]>e hest described as stilll)Oi'n, as 

 A tenuifolia is usually a plant of dry places, not watery hanks, as 

 he states. Unfortunately for the value of many of his records, 

 Mr. Richards has never made it a practice to press specimens. 

 Tlirough that cause his ]\uan Minor plant, wliatever it may lie, 

 must be referred to some other species tlian ^/. foiuifoVut. 

 According to " Topographical Botany," Cornwall and Devon do 

 not come within tlie range of this rather local plant. Probably 

 enough in all three cases aliove mentioned impoverished examples 

 of one of the three recognized varieties of A. Hfvpyllifol'ui were 

 gathered. 



Yicia lathy roides, Linn. For this plant my " Tentative 

 List" quotes no fewer than five Cornish records, freeing the 

 plant is not known to grow in Devon, and that I ha^-e not met 

 anyone who can show me a Cornish specimen, this is rather 

 amazing. Here again, and for reasons already given, credence 

 must be refused Jones' record for Fowey. Mr. Bastian's 

 statement that the plant is rather plentiful at Pendennis, near 

 Falmouth, is one of those puzzling records which one often 

 meets in botanical lists of bygone days, and for which no 

 satisfactory explanation can be offered. What he must have 

 examined was V . angmtifolia or its variety Bohartii, as the locality 

 has been frequently searched for V. lathyroides, and always 

 without success. (_)f AEr. Glasson's and Mr. Allen's sj^ecimens 

 if any were preserved, I can get no information, and Mr. Besley's 

 confession that he was only a beginner at botany when he 

 recorded the plant, puts his locality out of court. 



Myriophyllum Yerticillatum, Linn. When preparing 

 the material for his "Topographical Botany," Mr. H. C. Watson
