ISATIS. 



Hardy annual or biennial herbs (ord. Cruciferfe) 

 of little garden value, but interesting- because of the 

 dye furnished by one species, tiuctoria. This was 

 the \Voad of the ancient Britons, and has been 

 cultivated for many years for the sake of its dye. 



Principal Species : 



glauoa, 3', Jy., Aug., yel., a good border flower. 



ISERTIA. 



Tropical American trees and shrubs (ord. TCubi- 

 Jicea3), rarely cultivated, but possessed of handsome 

 flowers. Cuttings of the side shoots may be struck 

 in sandy soil in bottom heat, at any time in spring 

 or summer. Soil, loam and peat in equal parts, 

 with sand.

ISOLEPISo 



Although this genus (ord. Cyperacese) is now 

 referred to Scirpus, the name Isolepis is well 

 known, and still kept up in gardens, and likely to 

 be for some years. The genus is chiefly represented 

 by gracilis, which is in such constant demand for 

 decorative purposes. This species is really almost

sub-aquatic in its tendencies, and will do well 

 anywhere as long as it gets plenty of water. (Soil 

 is a secondary consideration, although two parts of 

 good loam, one part of leaf mould, and one-sixth 

 of sand produce the best results. 



To work up a stock quickly, old clumps should be 

 divided up into small portions, each division being 

 potted into a small pot in sandy soil, and started

into growth in a warm propagating frame. New 

 growth is soon made. It makes little difference 

 whether the old growths be cut away or not, for 

 young ones soon start. Old plants need to be 

 occasionally cut over, or they become rather untidy. 



Whilst Isolepises are commonly regarded as 

 greenhouse plants, they will do well out of doors 

 during the summer months, and, on the other 

 hand, they may be employed for edging the stages 

 in warm houses if no better subject offers. They 

 make good room plants. 



Principal Species : 



gracilis, 6", grh. grn. (correctly Scirpus nodosus).
