14 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
(plus d’un metre)), couchee (nageant probablement sur Peau) : feuilles 
tres-longues, pinnules tres-larges, un peu plus profonde’ment dentees 
en scie et ca et la lobees ; ombelles plus lo'nguement pedonculees ; 
pedoncules presque toujours (ou presque tous) plus longs que les 
ombelles; involucre principal souvent mais pas toujours present.” 
. . . “J’ai recu de Londres la var. c. en deux mauvais echantillons 
(dont Pun complete pourtant l’autre), sous le nom de H. repens , Koch. 
Ils ont ete recueilles aux environs d’Edimbourg.” Schultz gives the 
following description of repens: — “ Helosciadium repens (Koch, DC., 
a l’exelusion de la var. b. de sa FI. fr.) se distingue de P H. nodiflorum 
par des tiges couchees dans toute leur longueur, ramp antes, radicantes a 
tous les nceuds, par des feuilles dressees et formant avec la tige un 
angle droit, a pinnules toujours plus larges, ovales-arrondies, inegale- 
ment dentees en scie, ou lobees, a dents aigiies a ombelles toujours 
pedonculees, dont les pedoncules sont toujours plus longs que les 
ombelles et sont avec celles-ci redressees verticalement et forment avec 
la tige un angle obtus ; involucre principal, ayant toujours des folioles , 
en meme nombre (4 a 6) que les rayons et placees tout autour en cercleP 
Prof. Babington says, “The repens of Engl. Bot., 1431, is a form 
of nodiflorum. The plant sent seems to be the repetis of Koch, 
Schultz, &c. I have it in Schultz Herb. Norm., 481 ; Billot FI. Gal. 
et Germ, exsicc., 1201 ; Wirtg. PI. Crit,, 596; and apparently Fries. 
Herb. Norm., xiii., 42. Lange also sent it from Finland, and 
Leresche from Lausanne. I do not think this is the longipeduncu- 
latum. It has the general involucre of repens, not of nodiflorum. I 
have seen repens with long flower stalks, and should call this by that 
name.” Dr. Boswell writes: “This is not the plant of Schultz, but is H. 
repens, as is shown by the well-developed involucre, while in H. 
longipedunculatum it has seldom more than two or three leaves ; but 
this character is so variable, that I do not see that it is possible to 
separate longipedunculatum from repens, even as a variety.” 
CEnanthe fluviatilis, Coleman. Mr. Bailey sends the foliage 
only of this plant, from the canal at Navan, County Meath, 15th 
September, 1879. Not recorded for District 5 in Cyb. Hibern. 
Ligusiicum scoticum, L. Some specimens sent by Mr. H. Halcro 
Johnston, who reports it as common on the sea shore at Orphir, 
Orkney, nth August, 1879. 
Meum Athamanticum, L. Mr. A. Brotherston sends as new 
to County 80, one plant of this species from dry hilly pastures, 
Howpasley, Roxburgh, 21st June, 1879. 
A Galium is sent by Mr. Bolton King from wet meadows by 
the Thames at Old Windsor, with the following note : — “ Mr. H. C. 
Watson has examined specimens of this, and thinks it may be the 
diffusum of Hooker = cinereum of Smith ; but he is very doubtful 
about it.” Prof. Babington thinks it is a form of G. erectum , while 
Dr. Boswell thinks it G. Bakeri. 
Centaurea nigra , L. radiata. Sent by Dr. Boswell from 
Peterculter, Aberdeen, September, 1879, with the following note : — 
“ Frequent on Lower Deeside. I have never seen it in the South of 
England where the radiate form belongs to var. decipiens. The 
nearest approach to radiate C. nigra genuina about London is one 
with all the florets lengthened. This form occurs in Fife, where I
