THE PAGE-HEADING OF PERIODICALS 291 



before it can be ascertained to what the species belong. Thus in the 

 vokime before me, thirteen pages are occupied by the names, in three 

 columns, of species of Deadrohmm ; the name of the genus appears 

 only in the first column. The tjqDOgraphical arrangement of the 

 columns also differs inconveniently from the ordinary j)ractice by 

 which s^monyms are in italic and accepted names in roman : in Das 

 Pflnnzenreich all are in roman, accepted names being indicated by an 

 asterisk.

SHOET NOTES. 



Aplozia EiyuLARis Schiifner ix S. Lancashire (Y. C. 59). 

 Mr. H. C. Broome and I visited Bamford Wood, Ashworth Valley, 

 in July to find Nardia ohovata, discovered many years ago by 

 Mr. G. A. Holt, and were fortunate in meeting with a little of it. 

 On the damp shaley rocks by the side of the stream Mr. Broome col- 

 lected a small Aplozia that proved to be the paroicous A. rivalaris 

 Schiffner which is new to the county. Possibly the Aplozia riparia 

 (Tayl.) recorded in the Flora of Asliton-icnder-Lyne from Bamford 

 Wood may be the same, as probably the species growing on shaley 

 rocks as A. riparia will prove to be A. rivularis : specimens col- 

 lected near Ha3^field, Derbyshire, on similar rock as A. riparia are 

 A. rivularis. A. p)iomila (With.), of which A. rivularis is regarded 

 by some authorities as a variety, has a much narrower perianth and 

 other features- which to my thinking separate it from that species, 

 although it agrees with it in its paroicous inflorescence. Even when 

 neither subaquatic or aquatic A. rivularis retains, more the character 

 of A. riparia. — W. H. Pearson. 



Deteuxta neglecta Kunth. Mr. Lillie of Caithness has sent me 

 specimens of this from Loch Watten, which are very different in 

 appearance from the ordinary type, and answer well to the Arundo 

 sericea {A. stricta Timm.) var. angustata of Wahlenberg (Fl. Lappon. 

 1812, 28) which is described as " panicula elongata lineari, floribus 

 linearibus " ; I have also var. viridis (Torges in Asch. & Graebn. 

 Syn. Fl. Mitteleur, ii. i. 208: 1899) from West Norfolk, sent by Mr. F. 

 Kobinson. The flowers vary greatly, even in the same panicle. The 

 character drawn from the relative length of the hairs at the base of 

 the florets as half or three-fourths is apt to mislead : Anderson more 

 carefully says (yGraminece Scandinavice, 88) "flosculus glumis parum 

 brevior," which covers nearh' every state of the British j^lant. In the 

 detailed description in English Botany (ed. 3, xi. 56 : 1872) the 

 structure of the stems is not noticed. It is like a fluted column 

 (about 20 flutes) each flute having reversed stiff hairs ; these however 

 are caducous. In American Floras, the stems are described as 

 " glabrous," smooth throughout " ; but this is not so in the early 

 stages, the stems being quite rough, at least in British specimens. 

 The nomenclatm-e is also by no means settled, as correspondence with 

 Mr. A. J. Wilmott and Dr. Stapf shows. The latter remarks that 

 " it is by no means certain our species corresponds with the Central 

 European, or the Scandinavian plant. In fact the whole genus wants
