'22 THE JOURNAL UK BOTANY. 



September we found plenty of beautiful plants in cultivated ground 

 on the Somerset peat-moors between Ashcott Station and Glaston- 

 bury. We have constantly seen the species in similar ground and on 

 a similar soil in the black "warp" land of N. Notts, N. Lines, and 

 S.E. Yorks, often associated with Erysimum cheiranihoides, just as 

 it is in this Somerset habitat. If the plant be a colonist — though 

 both it and the Erysimum have been claimed as natives of peaty land 

 — it will rank with Galium Yaillantii and Chenopodium ficifolium, 

 rare plants which are very firmly established on these peat-moors, the 

 former occurring in extraordinary abundance in every piece of 

 cultivated ground between Edington and Ashcott Stations, and the 

 latter having been known there ever since the time of Thomas Clark. 



Pinguicula vulgaris has once more turned up on the peat-moors 

 after an interval of several years. One plant was observed by Mr. 

 T. H. Green in July towards the eastern border of the moors, and 

 we saw seven in the same enclosure in September. In another 

 enclosure near by, Nitella translucens grows in masses in several 

 pools left by peat-diggers. It was first discovered for the Bristol 

 district and for Somerset by Miss Honor Perrycoste when botanising 

 with us on the peat-moors in June 1919. 



The second new Bristol plant to be mentioned is Sparganium 

 neqlectum, which; curiously enough, has never before been noted in 

 our area, though recorded for both West Gloucester and N. Somerset. 

 Search has occasionally been made, and Mr. White has always antici- 

 pated its discovery. We were very interested, therefore, to see it in 

 good condition on October 6th, growing in a pool (an old strontia 

 digging) in a field near Yate Court, W. Glos. Mr. Salmon agrees 

 to the naming, and we have suspicions that the plant also grows on 

 the Somerset side within ten miles of the city. The characters of 

 the fruit are very unlike those of S. ramoswm and its variety 

 microcarpum, but do not tally with those in Mr. Beeby's plate in 

 certain minor points. 



Not far from Yate Court, we found last May a typical bush of 

 Crataegus occyacanthoides. This had not been known on the 

 Gloucestershire side of the district until Miss Todd found it this year 

 near Hiwkesbury, and Miss Roper has since reported another bush 

 from Wick war.

LXXXIII. The Botany of the 'Herald.' 



The Botany of the Voyage of H.M.S. ' Herald ' by Berthold 

 Seernann was published during the years 1852-1 S57, as stated on 

 the title-page, but in the absence of the original wrappers, no in- 

 formation as to the dates of the various parts can be obtained from 

 the book itself. As it contains numerous new species, the dates of 

 publication are of some importance, and the following table has 

 therefore been compiled from data furnished by contemporary 

 periodicals : —
