248 PECULIARITY IN PITH OF CUCURBIT. [ Sess. LEXI. 
As far as I could see, there was no appearance of any 
wound on the surtace of the stem. There was no disarrange- 
ment of the vascular bundles, nor any other irregularity in 
the appearance of the stem or distribution of the tissues. 
The material which I examined was among that which 
had been suppled from the Edinburgh Royal Botanic 
Garden for the use of students in the winter class of 
Botany. It consisted of short pieces of the stems of several 
cucurbits. I was able to find three or four short pieces, 
probably cut from the same plant, which contained this hair 
cavity, and in one I was able to trace its origin as above 
described. 
It extended for several inches along the stem, but I was 
unable to follow it to an end. It was difficult to say to what 
species of cucurbit the little piece of stem belonged, but 
aiter examining the large number of cucurbits which are 
grown in the Royal Botanic Garden I have come to the 
conclusion that it was very probably Benincasa cerifera. 
Dr. BorTHwick exhibited a series of lantern slides illus- 
trating the natural regeneration of coniferous woods under 
shelter trees as practised on dry, chalky soil in Bavaria. 
Mr. H. F. Tace, F.LS., exhibited a specimen of Hyoseya- 
mus niger, Linn., var, pallidus, Waldst. et Kit. The plant was 
sent to the Royal Botanic Garden, Edinburgh, in September 
1906, by Mr. Lumley, gardener at Culross Abbey, and was 
identified by Mr. J. F. Jeffrey as the Hyoscyamus pallidus ot 
Waldstein and Kitaibel. Mr. Lumley, in a communication 
accompanying the specimen, stated that the plant was found 
growing upon an embankment, the soil forming which was 
taken from below the Abbey during excavations carried out 
in 1905, and that the appearance of a plant, not hitherto 
observed in the district, in such a situation had given rise to 
much conjecture regarding its origin. 
Another specimen of the same variety, found by Mr. 
Jeffrey among the specimens in the herbarium of the Royal 
Botanic Garden, was also exhibited. The label on the plant 
ran as follows:—C. E. Parker, 1874, Teignmouth, Devon. 
Mr. Tage pointed out that the published records of the 
occurrence of the variety in Britain were very few, and
