NOMENCLATURE OF THE FLOWER. 85 



d. Cells are the spaces between the partitions and valves. 



e. Central column is the filament which unites the partitions, 

 and to which the seeds are generally attached. 



42. Capsules are said to differ with respect to their 

 number of valves, the number of cells, the number of 

 seeds contained, and also with regard to their figure and 

 substance. 



a. Number of valves maybe two, as in the celandine ; three, 

 as in the violet; four, as in the ludwigia, and so on. 



b. Number of cells may be one, as in the primrose ; two as in 

 the thorn-apple ; or many, as in different kinds of water-lily. 



c. Number of seeds may be one, two, three, or many as in 

 the poppy. 



d. Figure may be oblong, round, cylindrical, ovate, cornered, 

 and so on. 



e. Substance may be membranous, woody, elastic, fleshy, &c. 



SILIOUE AND SILICLE. 



43, The most common varieties of these species of 

 seed-vessels, are the round, compressed, articulated, 

 tortulose, rostrate, and drupaceous. 



a. Round as with the silique of the yellow fumitory, and sili- 

 cle of the penny cress. 



b. Compressed with level valves, as with the silique of the 

 cheiranthus annuus 



c. Articulated intercepted with joints, as with the silique of the 

 wild radish. 



d. Tortulose having swellings or knob.s here and there, as with 

 the silique of the garden radish. 



e. Rostrate having the partition very prominent at the apex, as 

 with the silique of the white mustard. 



f. Drupaceoxis-ifthe membrane is double, soft externally, and 

 hard within.
