 GARTNER has the following, with definitions annexed to 



them : 



1. Capsula, a dry, membranous, coriaceous, or woody pericarp, 



sometimes valveless, but more commonly dehiscing with 

 valves. Its varieties are, 



a. Utriculus, a unilocular one-seeded capsule, very thin and 



transparent, and constantly valvular; as in Cheno- 

 podium, Atriplex, Adonis. 



b. Samara, an indehiscent, winged, one- or two-celled cap- 



sule ; as Ulmus, Acer, Liriodendron. 



c. Folliculus, a double one-celled, one-valved, membranous, 



coriaceous capsule, dehiscing on the inside, and either 

 bearing the seed on each margin of its suture, or on a 

 receptacle common to both margins; as Asclepias, 

 Cinchona, and Vinca. 



2. Nux, a hard pericarp, either indehiscent or never dividing 



into more than two valves ; as in Nelumbium, Boragi- 

 neae, and Anacardium.
