The other kinds of splitting fruits 

 named above require but little de-

 illustrations will help to fix their 

 distinctive features in the memorj-. 

 Fig. 622 shows a tripartite, and 

 fig. 620 a quadripartite schizocarp 

 the former of the Garden Nastur- 

 tium (Tropceolum majus], the latter 

 of the Black Horehound (Ballota 

 nigra). Two quinquepartite schizocarps are depicted in fig. 623 one of 

 them in the act of splitting. They are fruits of the Bloody Cranesbill 

 (Geranium sanguineum). Fig. 621 is a multipartite 

 schizocarp of the Common Mallow (Malva sylves- 

 tris). 



Like the Touch-me-not Balsam (Impatiens 

 noli-me-tangere), of which we have already given 

 some account (p. 476), the fruits of the Bloody 

 Cranesbill are sling-fruits. " If you would wish 



to catch

 summer's morning before the dew

 By degrees the fruits will dry, and 

 if you watch them, you will be 

 surprised by some of them, on a

 and you may see first one and then 

 another of the carpels quickly

 of the style, opening at the same 



time by their face, so as to let this
