GLOSSARY OF TERMS. $25 



Ciliate Furnished with a row of hairs along the margin, like 

 eyelashes. 



Cluster crystals Minute globes of crystals contained in leaf 

 cells ; sometimes called sphaeraphides, and usually consisting 

 of calcium oxalate. 



Concentric Having several circles inside one another. 



Conchoidal Having a fracture somewhat concave, with curved 

 lines, as in Aloes. 



Cordate Shaped like the heart on playing cards. 



Coriaceous Having a leathery texture. 



Corm A more or less globular shortened stem, having mem- 

 branous scales, but no fleshy ones, as in Colchicum and 

 Crocus. 



Corolla Applied collectively to the inner row of coloured floral 

 leaves, whether distinct or united into one piece. When the 

 calyx and corolla are similar in colour and size, the term 

 perianth is applied, as in the Lily and Hyacinth, in which 

 there are two similar rows of three pieces ; the outer row 

 alternate and overlapping the inner row at the base. 



Cortex Applied to the outer separable portion of a stem or 

 fruit. 



Corymb An arrangement of flowers in which the flowerstalks 

 are of different lengths, but all rise to a level at the top, the 

 outside flowers opening first. When the central flower 

 opens first it is called a corymbose cyme. 



Cotyledons The seed lobes as seen when splitting open a 

 nut or almond. They contain the nourishment to support the 

 young plant while the root is being developed, when albumen 

 is not present. 



Crenate Leaves having rounded, not saw-like, teeth. 



Cruciform Arranged like a Maltese cross, as in the flowers of 

 the Wallflower, and other cruciferous plants. 



Cuneate Wedge-shaped. 



Cuticle The thin outer skin coating the epidermis, but not 

 usually separable. 



Cyme This term is added to any inflorescence in which the 

 central flower of the whole, or of a branch, opens first ; thus 

 the Elder has un umbellate cyme. 



Deciduous Falling off; applied to trees which are bare of 

 leaves in winter, or to the flowers which fall when the fruit 

 forms. If the calyx falls off as the flower opens, as in the 

 Poppy, it is said to be caducous. 



Decurved Curved downwards. 



Dehiscence A term applied to the opening of fruits.
