hausia) fQ3tida are stated on ray authority to grow at Purfleet, in 

 Essex, whereas, in fact, neither of them has been found there. At 

 the time of the publication of that work, it must be remembered that 

 Barkhausia taraxacifolia and Crepis foetida were not distinguished, 

 the plant, therefore, called Crepis biennis is now Barkhausia taraxaci- 

 folia. The Crepis fcetida was inserted in consequence of the cele- 

 brated William Curtis, author of the ' Flora Londinensis,' &c,, hav- 

 ing so pronounced a specimen in ray herbarium, owing, doubtless, to 

 the fruit being beaked, by which it will appear that this eminent bo- 

 tanist was better acquainted with the true Crepis biennis than with 

 the more common Barkhausia taraxacifolia. The siaecimen is bad as 

 to foliage, and it was simply from the fruit that Curtis conceived it to 

 be C. fcEtida. Having searched many times since and found no trace 

 of this species, I am well convinced that there is only Barkhausia ta- 

 raxacifolia to be found there. Here I shall take the opportunity of 

 saying that 1 differ from ray friend Babington in referring to ^Eng- 

 lish Botany,' f. 149, for Crepis biennis, ^^ except the fruit''' It ap- 

 pears to me that both figure and description belong to Barkhausia ta- 

 raxacifolia, more especially as nothing is said about the fruit being 

 added from another specimen. 1 had much pleasure, not long since, 

 in being shown by Mr. G. S. Gibson and Mr. Joshua Clarke, the 

 Crepis biennis at Littlebury, near Saffron Walden. I rather think I 

 once found it at Harlow, but my specimen is not far enough advanced 

 to judge. 



I am also quoted for Lathy rus hirsutus, " near the shore above 

 South End ; " this ought to have been Vicia bithynica ; Lathyrus 

 hirsutus grows at Hadley Castle sparingly, and at Rawreth in abun- 

 dance. 



Having given you my own erroneous habitats of Essex plants, I 

 will now notice those of others. Mr. Cooper, in the ' Flora Metropo- 

 litana,' inserts Lepidium Smithii, Winch. This, I suspect, T ought to 

 have put among ray own blunders ; for I once fancied I had found 

 Lepidium Smithii at Walthamstow, but T fear it was only L. campes- 

 tre with a somewhat persistent style. This I probably showed to ray 

 late friend Winch, as I do not believe he ever was at Waltharastow 

 except with me. 



Centmirea Calcitrapa. — " G. P., Woodford." If ever there, I sus- 

 pect it was planted by Warner. It grows wild abundantly in the 

 marshes near Plaistow. " G. P." does not mean " Great Pond," as 

 stated by Mr. Cooper, but Gravel-pit Pond. It is on the Forest, 

 nearly opposite Hart, the house in which the author of the ' Plants? 

 Woodfordienscs ' lived, and is still called Warner's Pond.
