Scapania planifolia Hook. — Good specimens of this rare and 

 fine species were collected last April in the neighbourhood of 

 Borrowdale, Cumberland, by Dr. Carrington and myself. This is 

 the first record for England. It was originally published by 

 Dillenius, who received it from Snowdon (Dill. Hist. Muse. p. 498, 

 n. 21, 1741), "Lichenastrum auriculatum Ornithopodii minoris 

 pinnatis ciliatis." The late Prof. Lindberg, who had the oppor- 

 tunity of examining the Dillenian Herbarium, confirms the opinion 

 that fig. 71, t. 21, represents Scapania planifolia (Lindb. Hep. 

 Utvec. p. 34, 1877). Withering, in his ' Botanical Arrangement of 

 all Vegetables growing in Great Britain,' vol. ii. p. 695, 1776, 

 names it Jungermannia ornithopodoides, and Dr. Carrington says : — 

 " If it were not that one held to the opinion that it is unwise to 

 disturb a well-established name, one would not hesitate to reinstate 

 Withering's specific name." Its distribution is somewhat singular; 

 it is found on mountains in the South of Ireland and Scotland ; no 

 other station has been verified for it in Europe. The Scapania 

 planifolia Hook, of Hiiben. Hep. Germ. p. 228, described as being 

 found in different parts of Germany, belongs to a form of Scapania 

 undulata speciosa Nees (Syn. Hep. p. 66), or partly to Scapania 

 nemorosa (Nees, Eur. Leb. 11, p. 434). Fine specimens of this 

 species have been collected in the Sandwich Islands — Maui — open 

 swampy ground, 6000 ft., D. D. Baldwin, 1875 ('Plants Hawaii- 

 enses,' n. 83), and Mr. Mitten records it from the East Indies 

 (Proc. Journ. Linn. Soc. vol. v. 1861). These English specimens 

 will be distributed in the forthcoming Fasciculus of ' Hepatica3 

 Britannicaa Exsiccate.' — W. H. Pearson. 



Potamogeton falcatus. — This species has grown during the 

 present year under unusually favourable conditions, in water of 

 sufficient and fairly uniform depth. Consequently I find a remark- 

 able return of apparent varieties to the original typical form, which 

 was first found growing in a deeper part of the ditch than the 

 doubtful states of the species inhabited. Some of these states, 

 only first noticed last autumn, I had felt inclined to refer to 

 P. hetcrophyllus, and one or two seemed to approach P. varians very 

 closely. But early in the present month I found all these forms, 

 by growing in deeper water, had reverted to true P. falcatus. Many 

 of the plants were just throwing up their flower-spikes, and I was 

 more than ever struck with the resemblance this immature state 

 of the species bore to plants of P. nitens then under cultivation 

 in my garden. Anxious to obtain a further opinion on the specific 

 value of my proposed segregate, I submitted living specimens to 

 Mr. N. E. Brown, of Kew, who has most kindly sent me the
