 GiERTNER has the following, with definitions annexed to 



them : — 



1. Capsula, a dry, membranous, coriaceous, or woody peri- 

 carp, sometimes valveless, but more commonly dehiscing 

 with valves. Its varieties are, — 



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



and transparent, and constantly valvular ; as in Che- 

 nopodium, Atriplex, Adonis. 



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



sule ; as Ulmus, Acer, Liriodendron. 



c. FoUiculus, 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, Cin- 

 chona, and Vinca. 



2. Nux, a hard pericarp, either indehiscent or never divid- 

 ing into more than two valves; as in Nelumbimn, Boraghiese, 

 and Anacardium. 



3. Coccum, a pericarp of dry elastic pieces or coccules, as in 

 Diosma, Dictamnus, Euphorbia. 



4. Drupa, an indehiscent pericarp with a variable rind, very 

 different in substance from the putamen, which is bony, as in 

 Lantana, Cocos, Sparganium, Gaura, &:c. 



5. Bacca, any soft pericarp, whether succulent or other- 

 wise ; provided it does not dehisce into regular valves, nor 

 contain a single stone adhering to it. Of this the following 

 are kinds : — 



a. Acinus, a soft, succulent, semi-transparent, unilocular 

 berry, with one or two hard seeds; as the grape, 

 Rivina, Rhipsalis, Rubus, Grossularia, &c.
