BOTANISTS ON THE PENNINES. 
G. CLARIDGE DRUCE, M.A., F.L.S. 
Tue International Phyto-geographical Excursion through the 
British Isles, which has been so skilfully organised by Mr. 
A. G. Tansley of Cambridge, after visiting the Norfolk Broads 
and the Derbyshire Dales, paid a. visit to Crowden on August 
8th, under the guidance of Dr. Moss. 
The party, which included Prof. Drude of Dresden, Prof. 
Graebner of Berlin, Prof. Massart of Brussels, Prof. Ostenfeld 
of Copenhagen, Prof. Schroeter of Zurich, Dr. Lindman of 
Stockholm, Prof. Cowles of Chicago, Prof. Clements of 
Minnesota, etc., walked up Crowden Great Clough where 
Orchis maculata L. var. precox Webster was found in flower, 
while the form of Juncus effusus with condensed inflorescences 
was common, a plant often recorded as J. conglomeratus ; 
the smooth stem of the former, however, ‘easily distinguishes 
it from the latter which has ribbed stems. 
On the Black Chew Head Moors the abundance of Rubus 
chamemorus was a special feature of the peat deposits. On 
the way down Chewbrook Clough the true Rumex Acetosella L. 
was noticed, the common British form being Rk. angiocarpus 
Murbech, and near Greenfield was Alchemilla vulgaris var. 
minor Huds. 
The company was entertained at dinner in the evening at 
the Midland Hotel, Manchester, by Prof. Weiss and Dr. Lang 
of Manchester. 
On Wednesday the gth, the members drove from Greenfield 
Station in motor-cars, kindly lent by members of the ‘ Cave’ 
Club of Huddersfield, under the guidance of Dr. T. W. Wood- 
head, to Saddleworth Moors. At Wessenden Head a new 
variety to Britain of the heather Calluna vulgaris var. Erikat 
was pointed out by Dr. Graebner, a variety named after his 
wife by Prof. Ascherson of Berlin. On Honley Moor Ulex 
Gallit was noticed in fine flower. 
At Honley the members were entertained by Miss Siddon 
to a lunch, after which they motored to Honley Old 
Woods, where Melampyrum pratense var. hians Druce, and 
a hybrid Birch between alba and tomentosa, were observed. 
West Wood and Heywood were visited by kind permission ~ 
of the Earl of Dartmouth. Near the latter place a new variety 
of Polygonum aviculare was pointed out by Dr. Lindman. 
Woodsome Woods and the interesting Hall were also 
inspected. In the woods the alien Geranium endressi was 
noticed, with a splendid display of the fern Dryopteris cristata 
Druce. 
The Party then motored to Huddersfield, where they were 
entertained at dinner by the ‘ Cave’ Club. at the George Hotel.
