528 GENERAL REVIEW. 



The Australian Pitcher-plant ( Cephalotus follicularis} is one 



A pitcher of Cephalotus follicularis, natural size, with two normal leaves. 



of the most singular plants in the order, and is easily propa- 

 gated by careful division or by root-cuttings. 



THE SNAPDRAGON AND LINARIA FAMILY ( Scrophulariacece). 



A group of showy-flowered annuals, herbaceous plants, 

 or shrubs, distributed nearly all over the world, from the 

 coldest regions in which the vegetation of flowering - plants 

 takes place, to the hottest places within the tropics. In 

 North America they are said to form a 36th of the flowering- 

 plants, and in the middle of Europe about a 26th. In 

 our gardens we have the following genera : Browallia, 

 Brunsfelsia, Salpiglossus, Schizanthus, Calceolaria, Verbascum, 

 Scrophularia, Celsia, Alonsoa, Linaria, Antirrhinum, Maur- 

 andia, Lophospermum, Phygelius, Paiclownia, Chelone, Pent- 

 stemon, Leucocarpus, Diplacus, Mimulus, Torenia, Sibthorpia, 

 Buddleia, Digitalis, Veronica, Gerardia, Pedicularis, Sanchezia, 

 and others. Nearly all the Figworts bear an abundance of 

 fertile seeds, and these germinate readily if sown in light 

 sandy earth. The hardy kinds, as Digitalis, Pentstemon, 

 Chelone, and others, may be best treated as biennials. 

 Phygelius, Pawlownia, Calceolaria, Sanchezia, Brnnsfelsia 

 (Franciscea), Browallia, and other shrubby or semi-shrubby 

 kinds, root freely from cuttings of the young or partly -har- 

 dened growth inserted in a close case, and these also may in
