CLIMBING SHRUBS

THE HERBACEOUS ELEMENT 
Always continuing the comparisons with the British Elota, the 
herbaceous element demands little comment. Generally speaking* 
the herbaceous plants of Simla are showier than the British species-. 
The principal and most striking diversity in the herbaceous 
vegetation of the two countries is due to the presence in Simla of 
a number of genera of the leading Natural Orders^ — Leguminosae* 
Compositae and Gramineae — which are altogether unrepresented in 
Britain. The same may be said of the Scrophulariaceae, Acam 
thaceae, Labiatae, Amarantaceae, Urticaceae and Araceae. On the 
whole, the petaloid monocotyledons of Simla are more conspicuous 
than those of Britain ; yet none probably is so effective as the 
bluebell ( S cilia nutans ) of British woods and meadows. Pro- 
minent among them is Lilium poly phy llum, the subject of the 
Frontispiece. 
THE FERNS OF SIMLA 
The ferns of Simla are so numerous that the late Sir Henry 
Collett never intended to include them in the present work, but he 
contemplated publishing an account of them in a separate volume. 
He collected material for this purpose, and I have before me a list 
of seventy-one species collected by him during one season. As 
may be seen from the Bibliography at p. lxvii several other persons 
have made a special 3 tudy of this class of plants* and Colonel
