 Such fruits as those of Labiates, Borage- 

 worts, etc., which consist of several dis- 

 tinct lobes, not terminated by a style or 

 stigma. 



Central Placenta. A column in the center of 

 fruits to which the seeds are attached. 



Centrifugal. A term applied to those kinds 

 of inflorescence which, like the cyme, 

 (which see,) flower first at the point or 

 center, and last at the base or circumfer- 

 ence. 



Centripetal. A term applied to those kinds 

 of inflorescence which, like the spike or 

 capitulum, (which see,) flower first at the 

 base or circumference, and last at the 

 point or center. 



Gentron or Centrum. In Greek compounds 

 equivalent to calcar, a spur. 



Cephalanthum.The capitulum or flower 

 head of Compositea 



Cephalium. A peculiar woolly enlargement 

 of the apex of the stem of Melocactus, 

 among whose hairs the flowers appear. 



Cephalodium. A knob-like shield, such as 

 occurs in the genus Scyphophorus. Also, 

 the capitulum or flower heads of Com-

Cephalophorum.A. term employed among 

 Fungi, sometimes to denote their recep- 

 tacle, sometimes their stipe. 



Cephalotacece. The Australian Pitcher 

 Plant, Cephalotus follicularis, a very curi- 

 ous herb, with radical leaves mingled 

 with pitchers, is a plant of very doubtful 

 affinity. It has been considered provis- 



CHA 



ionally as a distinct family, bearing the 

 name Cephalotaceae. It has been com- 

 pared with Rosacece, Crassulacece, and Ra- 

 nunculacece ; but, according to the latest 

 authorities, (Benthani and Hooker,) it is 

 now classed with the Saxifragacece. 



Cephalum. In Greek compounds equiva- 

 lent to the head or terminal mass, or 

 thickened end of anything.

Chaff. Small membraneous scales, the de-

Chailletiacece. A family of Dicotyledons 

 belonging to Lindley's Khamnal Alliance, 

 differing from Celastracece in their usually 

 notched petals, in the five distinct glands 

 which take the place of the perigynous 

 (which see) disk, and generally in the 

 want of albumen to the seeds. They are 

 remarkable also for the great tendency of 

 the peduncles to combine with the peti- 

 oles, so that the flowers, which are really 

 axillary, appear to spring from the leaf 

 itself at the summit of the petiole. The 

 flowers are small, in paniculate cymes or 

 compact clusters. There are usually five
