TRUE LAUREL AND BUTTER WORT FAMILIES. 361 



It does not appear to be sufficiently well known that all the 

 choice and comparatively tender varieties of fme-foliaged 

 Coleus may be grafted on rooted cuttings of C. Verschaffeltii 

 as a stock. Side-grafting in heat is the best method, and the 

 grafts should be surrounded by a bit of oiled silk, and then 

 tied with soft budding cotton. A bit of bladder will do as well 

 as the silk, but something is needed to prevent the tie cutting 

 the succulent base of the grafted cutting or scion. 



TRUE LAUREL FAMILY (Lauracece). 



A group of trees or shrubs inhabiting the cooler parts of the 

 tropics, North America, and represented in Europe by the true 

 Laurel of the poets (Laurus nobilis). Nearly all the plants of 

 this order contain fragrant oil, and the camphor of commerce 

 is obtained from the wood and leaves of Camphora qfficinarum, 

 the main supply being obtained in Formosa, whence it is sent 

 to Canton for sale to foreign markets. Cinnamon of the shops 

 is the produce of Cinnamomum zeylanicum and other allied 

 species. The plants in' this group are propagated by seeds, 

 which germinate readily in a moist bottom-heat of 65 to 75, 

 and cuttings of the young or partially-hardened growth are also 

 successful in a close case. Cuttings of the roots are found 

 useful in increasing many species which are cultivated in the 

 tropics, and layering is a sure method which rarely fails. In 

 the case of the true Laurel, hillock-layering is most successful, 

 although a fair proportion of cuttings may be rooted on a north 

 border if inserted in October, or even earlier. Seeds may also 

 be employed wherever obtainable. In the south and south- 

 western counties the Laurel fruits very freely ; and at Battle 

 Abbey the plant is thoroughly naturalised, and reproduces 

 itself from self-sown berries every year. 



THE BUTTERWORT FAMILY (Lentibulariaceoe). 



A small group of insect-catching plants, represented in our 

 gardens by Utrictilaria and Pinguicula, natives of bogs, 

 marshes, or rivulets, in nearly all parts of the world, but prin- 

 cipally in the tropics. Both the genera above cited are repre- 

 sented in the English flora. Utricularia alpina bears very 

 showy white flowers, the closed lips and long spur of which 

 remind one of some Linarias. Pinguicula grandiflora is a very 

 beautiful plant found near Killarney. The Utricularias are
