Apium nodiflorum, Reichb. f. Under the name Helosciadium 
nodiflorum the Rev. H. J. Riddelsdell and Mr. E. G. Baker print 
a valuable paper in ‘Journ, Bot.’ 1906, p. 185, on the puzzling 
forms of this species, of which it may be said in nature there is no 
sharp line of delimitation, although by rejecting intermediates we 
may arrange the plants into three or four groups. The authors issue 
the following clavis : — 
[Apium nodiflorum, Reichb.]^ Helosciadium nodiflorum, Koch. 
A. Involucre o or i or 2 bracts, in var. longipedunculatiim^

Var. vulgare (F. Schultz).

of the rays. 
* Roots at most of the nodes. Leaflets 5 — 7, sub- 
lanceolate. Var. ochreatuni (D. C.).
