cus campestris, Linn. * Herba Luziola vulgo ;" and the reason, as 
Gerard informs us, is, that the heads of the flowers shine in the 
night; ** wherefore in Italy they call it Luciola quia noctu lu- 
cet." Tabernæmontanus and Ruppius call the family Cyperella ; 
Scheuchzer, Haller, and Micheli, Juncoides; Willdenow (Hort. Be- 
rol.), Lamarck and Decandolle (Flor. Franc.), and Désvaux, have 
established the genus under the name of Luzula. The last-named 
botanist has published a paper on the subject in the Journal de 
Botanique, vol. i. p. 131; and the alteration has been recognised by 
our own learned and indefatigable countryman, Mr. Brown, in his 
Prodromus Flore Nove Hollandie. The different habit and striking 
character of the two families would have been enough to have 
caused their separation; but, sanctioned by these weighty autho- 
rities at home and abroad, it can no longer be a subject of doubt. 
In distinguishing the species of Luzule, I have derived great 
assistance from observing the shape of the seeds, and of what I 
have ventured to call the Coruncula, attached to them; the figure 
of which, if well observed, will set at rest any hesitation that may 
exist about the British species. The same appendage is incident 
to many of the real Junci, and may be particularly remarked in 
J. acutus, maritimus, triglumis, castaneus; and in the foreign 
J. grandiflorus, Linn., now made a new genus by Desvaux, on 
account of this striking character, under the name of Marsippo- 
spermum. The seeds of Narthecium ossifragum, which is nearly 
allied to the plants under discussion, have an integument of the 
same nature. 
Besides the attempt to adopt a new genus into the British 
Flora, I have given in the following pages what I conceive to be : 
amended characters of all the species of Juncus and Luzula yet 
discovered in Great Britain; and have added some few new 
ones, which were either imperfectly known, or regarded only as 
varieties.
