ORGANOGRAPHY. 



BOOK I. 



VII. Et^rio, Mr6. — (" Polychorion, MjV6. ;" Volysecus, Bewaux ; Amalthea, 



Desv. ; 'ErythrosXomnm, Desvaux), fig. 162. 



Ovaries distinct ; pericarpia indeliiscent, either dry upon a dry receptacle, as 

 Ranunculus, dry upon a fleshy receptacle, as strawberry, or fleshy upon a 

 dry receptacle, as Rubus. The last is very near the syncarpium, from which 

 it diflTers in the ovaria not coalescing into a single mass. It is Desvaux's 

 Erythrostomum. This term is applied less strictly by M. Mirbel, who admits 

 into it dehiscent pericarpia, not placed upon an elevated receptacle, as Delphi- 

 nium and PsBonia ; but the fruit of these plants is better understood to be a 

 union of several foUicules within a single flower. If there is no elevated 

 receptacle, we have Desvaux's Amalthea. The parts of an Etsrio are 

 x'i.chenia. 



Examples. Ranunculus, Fragaria, Rubus. 



VIII. Syncarpium. — (Syncarpium, JJic/i. ; Asimina, Z'ew. ) 

 Ovaries cohering into a solid mass, with a slender receptacle. 

 Examples- Annona, Magnolia. 



IX. Cynarrhodum. — (Cynarrhodum, Officin. Desvaux.) 



Ovaries distinct ; pericarpia hard, indehiscent, enclosed within the fleshy 

 tube of a calyx. 



Examjiles. Rosa, Calycanthus. 



Class III. Fruit compound. SYNCARPI. 

 Ovaria compound. 



Sect. 1. Fruit superior. 

 A. Pericarpium dry. 



X. Caryopsis. — ( Cariopsis, i?jc/i. ; Curio, Mirb.) 



One celled, one-seeded, superior, indehiscent, dry, with the integuments of 

 the seed cohering inseparably with the endocarpium, so that the two are undis- 

 tinguishable ; in the ovarium state evincing its compound nature by the pre- 

 sence of two or more stigmata ; but nevertheless unilocular, and having but 

 one ovulum. 



Examples. Wheat, Barley, Maize. 



XI. — Reg-ma, Mirb. ; — (Elaterium, Rich. ; Capsula tricocca, L.) 



Three or more celled, few-seeded, superior, dry, the cells bursting from the, 

 axis with elasticity into two valves. The outer coat is frequently softer than 

 the endocarpium or inner coat, and separates from it when ripe ; such regmata 

 are drupaceous. The cells of this kind of fruit are called cocci. 



Example. Euphorbia. 



XII. Carcerulus, il/irfi. ; — (Dieresilis, il/jri. ; Csenobio, Mirb.; Synochorion, 



Mirb.; Sterigmum, Desvaux ; Microbasis, Desvaux ; Polexostylus, 

 Mirb.; Saxcoh-dsis, Dec, Desv. ; Baccaularius, Z>e5i,'.) 

 Many-celled, superior : cells dry, indehiscent, few-seeded, cohering by a 

 common style round a common axis. From this the Dieresilis of Mirbel does 

 not differ in any essential degree. The same writer calls the fruit of Labiatre 

 {fig. 162.), which Linn»us and his followers mistake for naked seeds, Caeno- 

 bio : it differs from the Carcerulus in nothing but the low insertion of the style 

 into the ovaria, and the distinctness of the latter. 

 E.ramjtlcs. Tilia, Tropaeolum, Malva.
