164 SURFACE OF LEAVES. 



Glandidosian, glandular, as Jhipericum 

 montamnn, t. 371, and the Bay-leaved 

 Willow, Sallx pentandra. 

 Revohitum, revolute, when the margin is 

 turned or rolled backwards, as Andro- 

 7jieda polffoUa, ^.713, and Tetratheca 

 glandulosa, Eaot, Bot. t, 21. 



Linnaeus seems originally to have ap- 

 plied this term to the rolling of the 

 whole leaf backwards, as in Solidago 

 FiJ'gam'ea, Engl. Bof. ^.301, meaning 

 to use the expression margine revoliitinn 

 when the margin was intended ; but 

 this latter case being extremely frequent 

 and the other very rare, he fell into the 

 practice of using rcvolutum simply for 

 the margin. 

 Involutuni, involute, the reverse of the pre- 

 ceding, as in Pingiiicula, t. 70 and 

 145. 

 CondupUcatum, folded, when the margins 

 are brought together in a parallel di- 

 rection, as in Roscoea purpurea, Exot. 

 Bot. t. 108.

 face, applying equally to the leaf and to 

 the stem, have been already explained,
