NOTICES OF BOOKS AND MEMOIES. 



P. liicens. The serrated margins of the leaves and the small spikes 

 separate it from P. decipiens. — J. T. Boswell. 



ZannichelUa 2>ohjcarpa, Nolte. Brackish marsh near Belfast, 

 Ireland. — S. A. Stewart. The plant I send to the Clnh was 

 collected by me as Z. brachijstemon, though the very short style 

 and narrow carpels should have enlightened me ; it is abundant 

 in the brackish ditches of the ground reclaimed from the sea, 

 adjoining the People's Park, Belfast. There were few flowers 

 at the time, but the following I find on my notes : "Anther fila- 

 ments about one-eighth mchlong." Little attention seems to have 

 been given to the Ii-ish ZcmnicheUiw. Here, in my district, they 

 are rare. — S. A. Stewart. This is Z. polycarpa, Nolte, apparently 

 the true plant, of which I have been favoured with a specimen from 

 Mr. H. C. Watson, collected by Prof. Keichenbach atNolte's station, 

 Heiligenbavn, Schleswig, which is a stouter plant, with more con- 

 nivent, longer, smoother, and more sausage-like carpels with 

 shorter styles than in the Orkney plant, which is no doubt var. 

 tenuissima, Fries. — J. T. Boswell. 



Hahenaria vindis, Brown. Elevated rough pasture between 

 Plympton and Dartmoor, S. Devon. July 15, 1876. Previously 

 found this vear on the border of Dartmoor, near Tavistock, by Mr. 

 Francis Brent, of Plymouth.— T. R. A. B. 



Trichonema Columna, Reich. — Still abundant on Dawlish Warren 

 in April, 1876. I looked for it there in vain on March 23rd, the 

 season being late. On April 26tli, it was just opening into flower 

 in two widely- separated parts of the warren, not a single specimen 

 (that I could find) yet fruiting. By May 24th the plant had almost 

 w^holly disaiDpeared, Mr. Briggs and I on that day havuig to search 

 for an hoiu* or more before we came on a few withered specimens 

 (in fruit.) — W. Moyle Rogers. 



Carex Bcenninghauseniana, Weihe. Eskalt, near Whitehaven. 

 Found by Mr. Hodgson, and sent to me by Rev. R. Wood, of 

 Westward, who thought it nearer "axillaris.'' After carefully 

 examining the specimens, it seemed to me to be Boenninghauseniana. 

 I sent a specimen to Mr. H. C. Watson, with the query, ' Axillaris 

 or Boenninghauseniana !' His reply was, ' The Carex is Buenning- 

 hauseniana.' — A. Bennett.

The following is a summary of the author's exhaustive study 

 of the development of the capsule of Phascum cuapidatiun. We 

 may, however, omit the first steps, since the observations of 

 Hofmeister regardmg them are found to be in the main correct, 

 except that, after the formation of quadi-ant cells, each of these 

 latter divides, by means of an anticlinal wall, into an inner (seen
