THE BACCA. 283 



V/ilvcs, containing one or more Seeds, enve- 

 loped with pulp. It becomes more juicy in- 

 ternally as it advances to maturity, quite 

 contrary to the nature of a Capsule, though 

 the dilFerence between these two unripe 

 fruits may not be discernible, and though 

 some true Berries, Mhen fully ripe, finally 

 become of a dry and spongy texture ; but 

 they never open by valves or any regular 

 orifice. Examples of a Bacca are seen in 

 Atropa Belladonna^ Engl. Bot, t. 592, 

 and Ribes, t. 1289—92. The same part 

 in Heckra, f, 1267, is of a more mealy 

 substance. In Cuciibalus, t. 1577, the 

 coat only is pulpy. In TrientaUs^ t. 15, 

 the coat becomes very dry and brittle as 

 soon as ripe, and the cavity of the fruit is 

 nearly filled by a globular columella. See 

 Giertner, t, 50. 



Bacca co?jiposita, f. 186, a Compound 

 Berry, consists of several single ones, each 

 containing a seed, united together, as in 

 Rt/hus, the Raspberry, Bramble, &c., Engl, 

 Bot. ^ 715, 716, 826, 827- Each of the 

 separate parts is denominated an Acinus^ 

 pr Grain, which term Gaartner extends to,
