ENQUIRY INTO PLANTS, VII. ix. 2-4 



There is also much difference as to the flowers 

 between herbaceous plants and trees ; for in trees l 

 most of the flowers are white, while some are slightly 

 reddish, others are greenish or greenish-yellow, but 

 none of them 2 have distinct gay colours; while in 

 herbaceous plants the flowers shew many and various 

 colours, both simple and in combination, and further, 

 some of them are scented, others not. Again 3 trees 

 produce all their bloom at once, while some herba- 

 ceous plants have a succession of flowers, as we said 4 

 of basil ; wherefore it is in flower for a long period, 

 as are many other herbs, such as heliotropion and 

 chicory. 



There are also many differences in the roots, and, 

 in a way, the differences in these are more obvious ; 

 some are woody, some fleshy and fibrous, just as in 

 the cultivated kinds, as are those of corn and most 

 kinds of grass. Again the roots themselves exhibit 

 in each case very many differences in colour smell 

 taste and size ; some are white, some black, some red, 

 as those of alkanet and madder ; some are yellowish, 5 

 or the colour of wood. 6 Again there are roots which 

 are sweet, bitter, pungent, fragrant, evil-smelling ; 

 and some are medicinal, as has been said elsewhere. 



There are also differences between those with 

 fleshy roots ; the roots of some are round, of some 

 oblong and acorn-shaped, as those of asphodel and 

 crocus ; 7 some consist of several layers, as those of 

 purse-tassels squill and others which belong to 

 that class, onion long onion and others like
