BOTANICAL SOCIETY OF EDINBURGH XIX 



Sir DvcE Duckworth also sent for exhibition a cone 

 from the classical pine forest at Ravenna, gathered in 

 1865. After a lapse of ten years he had extracted and 

 planted some of the seeds, which all germinated and grew 

 well. They were transplanted in different parts of Berks 

 and Surrey. Those planted on chalky soil, however, died, 

 but those planted in sandy soil thrived well. One of the 

 best specimens is growing in the garden of the Duke of 

 Newcastle at Ascot, and is 18-20 feet high and in fine 

 condition. A cone from it was also shown. 



The Honorary Secretary exhibited Whytockia, a new 

 genus of the Gesneraceae, the generic name being chosen in 

 honour of the present President of the Society (see p. 338). 



A sample of German war tobacco was exhibited on 

 behalf of Colonel MacDougall. It was mostly composed 

 of beech leaves ; it also contained beech buds, beech petioles, 

 beech twigs, and pieces of petioles of a species of Nicotiana.
