*^^ SUBSTANCE, &c. OF LEAVES. 



Cticullatum,/. 102, hooded, when the edges meet in 

 ^ the lower part, and expand in the upper, as those of 

 the curious genus Sarracenia. Curt. Mag. t, 780 

 and 849, and S. adunca, Exot. Bot. t. 53.(78) 

 Appendiculatum, f. 103, furnished with an additional 

 organ for some particular purpose not essential to a 

 leaf, as Dloncea miiscipula^ Curt. Mag. t. 785, cul- 

 tivated very successfully by Mr. Salisbury, at Bromp- 

 ton^ whose leaves each terminate in a pair of toothed 

 irritable lobes, that close over and imprison insects ; 

 or Nepenthes distillatoria^ Rurnph. Amboin. v. 5. t. 

 59, yi 2, the leaf of which bears a covered pitcher, 

 full of water. Aldrovanda vesicidosa^ and our Utricu- 

 larWy Engl. Bot. t. 253, 254, have numerous blad- 

 ders attached to the leaves, which seem to secrete air, 

 and float the plants. 



Many of the preceding terms applied to leaves arc 

 occasionally combined to express a form between the 

 two, as ovato-lanceolatum^ lanceolate inclining to ovate, 

 or elliptico-lanceolatum^ as in the Privet, Engl. Bot. t. 

 764. When shape, or any other character, cannot ht 

 precisely defined, sub is prefixed to the term used, as 

 suhrotuiidum, roundish, subsessile, not quite destitute of 

 a footstalk, to which is equivalent subpetiolatum, ob- 

 scurely stalked. By the judicious use of such means, 

 all necessary precision is attained. It is to be wished 

 that authors were always uniform and consistent, at least 



(7S) [A leaf is said to be hooded, whether the edges unite so 

 as to form a perfect cavity, as in Sarracenia, or Fivesaddle flow- 

 er ; or whether they simply meet without cohering, as in Viola 

 cucullata^
