28 PICTURE OF ORGANIZED NATURE. 



11. Of the Order of Flower- de- Luce (Irides), the 

 common one (Iris pseudacorus) is a native of Lap- 

 land ; and some species of the Saffron Genus (Cro- 

 cus) are inhabitants of lofty mountains. The Corn- 

 Flag (Gladiolus communis) occurs in the middle of 

 the Temperate Zone. But most species, and the 

 handsomest of the kind, become common in those 

 regions which lie in the 30th degree of latitude, 

 passing from hence into the Warm Zone. This is 

 the case especially, with the Genus Ixia, Morcea, 

 Antholyza, Wachendorfia, Dilatris. 



12. The Hydrocharides are natives of the Tempe- 

 rate Zone. But the Water-Lilies (Nymphcea alba 

 and lutea), which are of this Order, occur also in 

 Lapland. 



13. The Rushes (Junci) first display themselves in 

 flowers without colour, and in the shape of Grasses, 

 in the neighbourhood of the snow line. They bear 

 coloured flowers in the Water-Plantain (Alisma), and 

 the Flowering-Rush (Butomus) : in which manner 

 they pass into the Torrid Zone, of which place the 

 greater number and finer sorts are natives; for 

 instance, the Commelinas. 



14. The Order of the Cyperoidete is closely related 

 to the Grasses. They all bear a strong resemblance, 

 in their growth and flowers, to the Grasses ; among
