ENQUIRY INTO PLANTS, I. v. 1-2 



of special differences between individual kinds ; and 

 after that we must t^ike a wider range, making as it 

 were a fresh survey.^ 



Some plants grow straight up and have tall stems, 

 as silver-fir fir cypress ; some are by comparison 

 crooked and have short stems, as willow fig pome- 

 granate ; and there are like differences as to degree 

 of thickness. Again some have a single stem, others 

 many stems ; and this difference corresponds - more 

 or less to that between those which have side- 

 growths and those which have none, or that between 

 those which have many branches and those wliich 

 have few, such as the date-palm. And in these 

 very instances we have also differences in strength 

 thickness and the like. Again some have thin 

 Ijark, such as bay and lime ; others have a thick 

 Ijark, such as the oak. And again some have 

 smooth bark, as apple and fig ; others rough bark, 

 as 'wild oak' (Valonia oak) cork-oak and date-palm. 

 However all plants when young have smoother 

 bark, which gets rougher ^ as they get older; and- 

 some have cracked bark,* as the vine ; and in some 

 <;ases it readily drops off, as in andrachne apple ^ 

 and arbutus. And again of some the bark is fleshy, 

 as in cork-oak oak poplar ; while in others it is 

 fibrous and not fleshy ; and this applies alike to trees 

 shrubs and annual plants, for instance to vines 

 reeds and wheat. Again in some the bark has more 

 than one layer, as in lime silver-fir vine Spanish 

 broom <* onions " ; while in some it consists of only
