from which it has hitherto been recor.lecl. Its appearance in Surrey 

 can hardly hi considered anything but sporadic, and it is remarkable 

 that it should be fruiting in what one would think so uncomfortable a 

 situation for a moss which ts at home in the crevices of mountain 

 rocks, and perhaps most common in the Arctic regions. Koth states 

 that it occasionally descends to the plains, as " bei Seeheim in der 

 Bergstrasse, Hessen." The adaptability thus displayed is perhaps the 

 reason why it has attained so wide a geographical distribution ; it is 

 found from 11,000 ft. alt. to near sea-level (in the present case), and 

 from very high latitudes in the Arctic to Algiers and Ab^^ssinia; 

 it rano-es'over nearly the whole of the North Temperate Zone, and 

 also occurs in New Zealand. Its appearance in Surrey is very note- 

 worthy. — H. N. Dixox. 



VERONrcA POLTTA Fr. (Nov. Fl. Suec. p. 2, 1814). In the 

 London Catalogue, ed. 10, and in Mr. Druce's List, this name is 

 replaced by V. cUcli/ma Ten. (1811). In his Mantissa III, p. 169, 

 Fries strongly protested against that identification : — " My plant is 

 absolutely V. agrestis Tenore ; as is proved by specimens from his 

 own hand, and from Professor Wahlberg, who gathered it in Tenore's 

 company. The description of V. agrestis Tenore v.c. [vidi cultum ?] 

 in Fl. Med. Univ. so clearly exhibits all the marks of V. j^olita, that 

 not even the slightest doubt can be fairly raised about its being a 

 synonym. Wiiat V. didyma Tenore may be, I cannot so fully show 

 (his cultivated specimens seen by me belong to V. opaca, as lieichen- 

 bach has already pointed out) ; but, as it is diagnosed by " calyces 

 leaf-like, toothed, much larger than the corolla," it can by no means 

 be referred to V. poVita, but, word for word, exactly tallies with 

 r. a(/restis var. cahjcida, Nov. 1. c. [p. 2] {V. calycida being wrongly 

 indicated as having been put forward by me as a species) : and, as 

 the latter is more like V. polita than V. agrestis in its ovate shining 

 leaves, and has often been sent by the most acute botanists for 

 T. poJita (Reichenbach, too, separates it fi-om V. agrestis, and refers 

 it to V. polita), no doubt, to my mind, reiiiains that the name of 

 V. didyma has been transferred to V. polita by a similar confusion" 

 [translated from the Latin]. In face of such a detailed refutation, it 

 seems uriadvisable to displace V. polita Fr., about which there is no 

 uncertainty. — Edward S. Marshall.
