SHORT NOTES. 



Chara fragilis and C. delicatula. In Braun's account of the 

 Characeae in Cobn's Krypt. Flor. Schles. (1876) Chara delicatula 

 Agardli was treated as a species apart from C fragilis Desv., 

 of which it had previously been generally regarded as a variety. 

 In Braun and Nordstedt's Fragmente einer Monographie der 

 Characeen (1882) it was treated as a subspecies, and this latter 

 course was followed in the ninth edition of Babington's Manual. We 

 have lately been examining a considerable number of specimens of 

 the two plants, and the characters which separate them appear to us 

 sufficiently important to warrant their being treated as distinct species. 

 C. fragilis, using the name in the restricted sense, has only rudi- 

 mentary stipulodes, the primary and secondary cortical-cells of equal 

 size, and no apparent spine cells : C. delicatula has well-developed 

 stipulodes of one or both series, the primary cortical-cells distinctly 

 larger than, often twice the diameter of, the secondary cells, and 

 spine-cells clearly discernible though usually only papilliform. It 

 was not until some years after an attempt to work out the distribu- 

 tion of the British Charophytes was begun, that the difference 

 between the two sections of C. fragilis (sens, lat.) was appreciated; 

 hence a number of the earlier records cannot be apportioned to either, 

 and their separate distribution is therefore only imperfectly known. 

 We shall be glad if British and Irish botanists will collect and 

 examine specimens of any of these plants they may come across, wdth 

 a view to comj^leting the record of their respective comital distri- 

 butions. — J. Groa^es and G. R. Bullock- Webster. 



Impatiens glandulifera Boyle. This is not recorded in Prof. A. 

 H. Trow's Flora of Glamorgan. It grows abundantly in the meadows 

 on either side of the river Ely for a distance of two miles west from 

 the village of Peterston. A specimen from that locality has been 

 added to the National Herbarium at the Cardiff Museum. — P. Blount 



MOTT. 



JuNCUS EFEUSUS SPIRALIS (J. Bot. 1918, 358). This form is 

 exceedingly abundant in Orkney — about every third effusus one comes 

 across in the valleys of the mainland is spiralis. In 1906 I sent 

 specimens to Prof. Balfour, at whose suggestion I wrote a note which 

 is published in Trans. Bot. Soc. Edinb. xxiii. 233. — Magnus Spence.

Although bearing date 1917, copies of this volume only reached 

 England towards the end of last year. The title is in some respects 

 a misnomer, inasmuch as some of the omitted species have hitherto 

 been recorded onl}" from the Kimberley District or the country to the
