REPORT FOR 1914 OF THE BOTANICAL EXCHANGE CLUB 91 



petalorum lobis late ovatis.' There are specimens like this in 

 the British Museum from one or two Enghsh localities, and also 

 from the Continent." — A. B. Jackson. " This must be an arvense 

 form, and it has the uppermost stem-leaves broad-based, one of 

 the characters, according to Rouy and Foucaud (Fl. Fr.) of var. 

 latifolium Fenzl, but I have no authentic examples to compare. 

 I have never seen this beautiful luxuriant form in Surrey." — C. E. 

 Salmon. "Ripe fruit is not available in these examples, but 

 C. arvense L., var. latifolium Fenzl. [G. grandifiorum Gilib.) is like 

 this, a tall form with broad leaves and large flowers, but I have 

 seen no example." — J. A. Wheldon. "This is a rather notable 

 form of C. arvense Linn., and appears to agree very well with the 

 description of C. arvense L., var. latifolium Fenzl, in Rouy and 

 Foucaud, Fl. de France iii, p. 203. The description given of this 

 var. is as follows : — " Feuilles cauHnaires, surtout les superieures 

 a base large, ovales-oblongues ou sub-lanceolees celles des 

 fascicules et des rameaux etroitement lanceolees, toutes pube- 

 scentes ou poilues sur les deux pages ; tiges assez elevees ; 

 petales {\ lobes ovales." — C. E. Britton. " An extraordinary 

 plant, wdiich I think comes under C. arvense L. It comes nearest, 

 of the vars. given in Rouy and Foucaud, to their e. latifolium 

 Fenzl, but the stems, pedicels, and calyces are densely glandular." 

 — E. S. Marshall. 



Lotus tenuis Waldst & Kit. Rough pasture, clay washing on 

 chalk, under " Eagle's Nest," Offley Hill, Hitchin, Herts, v.-c. 20, 

 August 10th, 1914. L. tenuis in N. Herts occurs (1) on heavy 

 boulder clay ; (2) on the chalk scarp, in poor soil with a washing 

 of marl or of clay from the caps on the hills. It generally occurs 

 with L. corniculatus, and there appear to be intermediate forms. 

 At Pagham, W. Sussex, v.-c. 13, it occurs on the sea bank in 

 apparently drier situations, though perhaps moisture soaks up 

 from below. — J. E. Little. 



Senecio lautus Forst. Banks of Tweed, Selkirk, v.-c. 79, 

 September, 1914. Native of Australia. Growing in this neigh- 

 bourhood it does not increase by its own fruits, but by rooting all 

 along its old wood. On a plant of tw^o years' growth I counted 

 70 old stems, and the branches shooting from them each bearing 

 on an average 190 blossoms. — I. M. Hayward. 



Cnicus oleraceus L. Marshy meadow at Limehaugh, E. Perth, 

 August 11th, 1914. This thistle appeared first in 1911 in a marshy 

 meadow close by the River Tay, which in very high floods is liable 

 to be inundated. It has appeared every summer since to the 

 number of 60 or 70 flowering heads. As the meadow is cut about 

 the end of August, it is doubtful if the plant produces ripe seed so 

 as to give it the chance of becoming thoroughly naturalised. 

 Although not a native of Britain it is common in Central Europe 

 and in Scandinavia. — W. Barclay 



Chenoyodium murale L. Trent Meadows, Nottingham, October 

 7th, 1914. This species was growing in fair abundance on waste 

 ground adjacent to the site of the abortive Nottingham Exhibition 

 of 1913. In the same field Crocus nudifiorus is abundant, and
