The Irish Naturalist, 
April, 
H. INUNDATUM, Koch. 
A variety which I do not find in EngUsh manuals is var. 
fliiitans, Fr., Novit. Fl. Suec, p. 182 (1832-42). It is 
simply the type plant with all its leaves divided into capillary 
segments. There is a specimen in the British Museum 
named by Fries himself, and I have therefore no hesitation 
in placing to this variety plants from E. and W. Gloster 
(Canal at Sapperton and Cirencester), and Isle of Wight 
(Hb. Bailey) ; from Connor Hill, Kerry (1853, coll. D. 
Ohver); R. Maam, Galway (Hb. W. A. Shoolbred), R. Clare, 
at Tuam, Galwa^^ (Hb. Praeger). Mr. Bailey has also 
specimens from Cumberland and Connemara which must 
be placed under the variety. As however, intermediates 
occur in Gloster between the type and the variety, it may 
be doubtful whether var. fluitans, Fr., is really anything 
better than a " state." 
Resuming the conclusions of my paper on Helosciadium 
Moorei (Irish Nat., Jan., 1914), I venture to rearrange the 
British forms of Helosciadium on the following lines : — 
Helosciadium nodiflorum, Koch, 
f. vulgare. 
/. ochreatum. 
/. pseudo-repens. 
var. longipedunculatum, F, Schultz, 
f. simulans. 
H. repens, Koch. 
X H. Moorei Riddelsdell (inundatum x nodiflorum). 
/. subnodiflorum (f. quae potius H. nodiflorum 
simulat quam H. inundatum, foliolis minus tenuiter 
dissectis). 
/. subinundatum (forma plerumque elatior, 
foliolis inferior ibus tenuiter dissectis, caule teneri, 
etc. ; simulans H. inundatum). 
H. inundatum, Koch. 
var. fluitans, Fr. 
As Helosciadium is usually grouped in this country under 
Apium, it is as well to publish the same list under that
