LEAF 



Ga), involute (margins rolled inwards), revolitte (outwards), redinate 

 (apex bent down to base), com'ohde (rolled spirally, as in Musa) ; 

 conduplicate 1. overlapping younger ones thus < < > , as in Iris, 

 are called equitant. 



When a character is not accurately described by one of the terms 

 given, but is rather half-way between two, both are used; thus a 1. 

 may be linear-lanceolate or ovate-cordate. Sub-, meaning 'nearly,' is 

 often used as a prefix to adjectives, e.g. subsessile, subacute. As an 

 example of the use of these technical terms, we quote from Lindley 

 the descriptions of two leaves : 



Lilac: leaves opposite, exstipulate, roundish-cordate, very acute, 

 thin, smooth, rather longer than the linear channelled petiole. 



Garden Strawberry : leaves all radical, ternate, dark-green, some- 

 what shining, very coarsely serrated; with strong parallel oblique 

 veins, silky beneath ; leaflets nearly sessile, roundish oblong, entire 

 towards the base, shorter than the semi-cylindrical hairy petioles; 

 stipules membranous, lanceolate, acuminate, half adnate.
