GYNANDRIA. ^l 



or three feet. The column of the Stamina, which is 

 peculiarly constructed, of one of the species of this 

 Genus, Stylidum irriialile, exhibits a remarkable in- 

 stance of irritability : when touched, it throws itself 

 backward into a curved form with great quickness, 

 and in about half an hour returns to its fonner posi- 

 tion. The only specimen of this curious plant that I 

 have seen is in the garden of Messrs. Lee and Ken- 

 nedy, at Hammersmith. 



the leaves, as the stalk in theDionae muscipula, which springs 

 from the Bracieay already referred to, Class X. The Trientalis 

 and Fuchsia also afford good examples of Pedunculi. 



V. Petiolus, is a leaf stalk, and exclusively applied to that 

 meaning, of vrhich good examples are infinitely numerous : 

 the Pepper, Cherry Laurel, Meboria, &c. will serve as illustra- 

 tions. Class II. XII. XX. 



VI. Stipes, the base of a frond, or a kind rf stem 

 passing into leaves, or not distinct from the leaf; also the 

 thread, or slender stalk, which supports the pnppus^ or down, 

 connecting it with the seed : see Illustration of Class XIX. The 

 stem of a Fungus, or Mushroom, is likewise called Stipes: see 

 Class XXIV. 



VII. Frons, is the stem-leaf and fructification united, 

 that is, the flowers and seeds produced from the leaf itself, as in 

 Ferns, Polypodium, Class XXIV. : it is a term also applied to 

 Lichens, and others in vehich the whole plant is either of a 

 crustaceous or leafy substance, from which the fructification 

 immediately proceeds.
