of a plant give place to others totally different 

 from them and from the natural habit of the 

 genus, as in many Mimosa of New Holland ; see 

 M. vertitillata, Curt. Mag. t. 110, and myrti- 

 Jblia, t. 302 ; also Lathyrus Nlssolia, Engl. Bot. 

 t. 112. 



Cucullatum, f. 102, hooded, when the edges meet 

 in the lower part, and expand in the upper, as 

 those of the curious genus Sarracenia. See 

 Curt. Mag. t. 780 and 849, and S. adunca, 

 Exot. Bot. t. 53. 



Appendiculatum, f. 103, furnished with an addi- 

 tional organ for some particular purpose not es-

 Mag. t. 785, cultivated very successfully by Mr.

 close over and imprison insects ; or Nepenthes 

 distillatoria, Rumph. Amboin. v. 5. t. 5$ } f. 2, 

 the leaf of which bears a covered pitcher, full of 

 water. Aldrovanda vesicutofa, and our Utricu- 

 laritf, Engl. Bot. t. 253, 254, have numerous 

 bladders attached- to the leaves, which seem to 

 secrete air, and float the plants. 

 Many of the preceding terms applied to leaves are 

 occasionally combined, to express a form between the 

 two, as oixftd-fartceolatum,}&ncol&te inclining to ovate, 

 or elfiptkO'lanceofatwn, like the Privet, Engl. Bot. 

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