 orifice of the tube of the corolla of the 

 Narcissus, etc. Corona xtaminea, a coro- 

 net formed from transformed stamens. 



Coronans. Situated on the top or crown 

 of anything. Thus, the limb of the calyx

 crowns the nucule (which see) of Chara, 

 etc.

 pus ligneum or lignosum signifies the mass 

 of the woody tissue of a plant, and corpus 

 medullare the mass of its cellular tissue in 

 the pith. 



Corpuscle. A small body; a particle of 

 anything. 



Corpuscules. The spore cases of certain 

 Fungi. Vermiform corpuscules are the 

 spiral vessels in a contracted, strangled, 

 or distorted condition. 



Corrugated, Corrugative. When the parts 

 are crumpled up irregularly, as the petals 

 of the Poppy or the skin of some seeds. 



Cor Seminis. An old name for the embryo. 



Cortex. The bark. Also the peridiuni 

 (which see) of certain Fungi.

Corymb, (adj. Corymbose.) A raceme whose 

 pedicels grow gradually shorter as they 

 approach the summit, so that the result 

 is a flat-headed inflorescence or flower 

 head, as in Candytuft, etc. A compound 

 corymb is a branched corymb, each of 

 whose divisions is corymbose. 



CorymbifercK. Corymb-bearing Composite 

 plants, a sub-order of the natural order 

 Qompositoe or Atteracece, containing plants 

 with numerous flowers on a common re- 

 ceptacle, forming a head surrounded by 

 a set of floral leaves or bracts called an 

 involucre. Such plants as Chamomile, 

 the Ox-eye Daisy, the Dahlia, Sunflower, 

 Cineraria, Ragwort, Groundsel, etc., be- 

 long to this sub-order. See Asteraceae. 



Corymbose. Formed or arranged after the 

 manner of a corymb, as in Lopezia coro- 

 nata. 



Corymbosely-cymose. Between a corymb 

 and a cyme. 



Corymbulose. Formed or arranged in many 

 small corymbs, as in Crassula corymbulosa. 



Corynidia. Processes sunk into the mar- 

 gin of the germinating leaf of Ferns, and 

 containing spiral threads. 



Costa. The midrib of a leaf; that part 

 which is a direct extension of the petiole, 

 and whence the veins arise ; a leaf may 

 have several costce. 



Costate. When there is only one rib, as 

 in most leaves. The term is also the 

 adjective of costa, and then means ribbed. 



Costato-venose. When the parallel side veins 

 of a feather-veined leaf are much stouter 

 than those which intervene. 



Cottony. When the pubescence is com- 

 posed of long, soft hairs, which are en- 

 tangled or interlaced, resembling raw 

 cotton in appearance.
