MIRBEL 5 S CLASSIFICATION OF FRUITS. 
Bacca , contains all the fruits of this order not found in the other 
genera. The pericarp of the currant, whortleberry, orange, bar¬ 
berry-, potato, grape, &c., are 
found here. Fig. 104, repre¬ 
sents a spherical berry, a, of 
the genus Ribes ; it is known 
by the name of wild goose¬ 
berry ; the fruit is many- 
seeded, as may be seen at 
5, which represents it as cut 
vertically ; c, is the same cut 
transversely. 
CLASS II. ANGIOCARPES. 
Fruits which are covered by a bract or foliaceous envelope. 
This class is divided into five genera, as follows; 
1st. Strobilum or cone , a collection of carcerular fruits concealed 
by scales, formed of bracts or peduncles, whose union produces a 
globular or conical body, as the juniper, pine, &c. Fig. 105, repre¬ 
sents the fruit of the pine, which is composed of woody, close, and 
indehiscent cupules. The glands are membranous, One-celled, and 
one-seeded ; a, is an entire strobilum ; 5, is the same, cut vertically; 
the placenta, extending lengthwise through the fruit, is large. The 
pine-apple, Bromelia 3 is of this genus of fruits. 
2d. Calybion ,* (from kalubion , a little cabin;) fruits of this genus 
are composed of a cupule or cup of variable forms, and of carcercu- 
lars enveloped entirely, or in part, by the cupule. The carcerculars 
of calybions are called glands. The gland of the oak is partly con¬ 
cealed in its cupule, that of the beech entirely concealed, and also 
of the yew, ( Taxus ;) in the latter are two cupules, pne enclosing 
the other; the exterior one is succulent, and of an orange red; the 
interior, which is hard and woody, encloses the fruit. 
* This includes what some writers call the gland and the nut.
