HENDERSON'S HANDBOOK OF PLANTS. 



CHL 



nute flowers are in simple or branched 

 terminal spikes, often articulate, as in 

 Gnetum. There are but very few species, 

 all tropical, and contained in two genera, 

 Chloranthus in Asia and Hedyosmum in 

 America. 



Chloranihia.A. monstrous development of 

 the floral organs, where they become 

 more or less green, and partially assume 

 the character of leaves, as in Eoses, 

 Dahlias, etc. 



Chloro. In Greek compounds chloro 

 means green. 



Chlorochrous. Having a green skin. 



OUorophyL The green resinous coloring 

 matter of the leaves and other parts, con- 

 sisting of minute grains, lying loosely in 

 the cells of the tissue. 



Chlorosis. A disease to which plants are 

 subject, and often admitting no cure. It 

 consists in a pallid condition of the plant, 

 in which the tissues are weak and unable 

 to contend against severe changes, and 

 the cells are more or less destitute of 

 chlorophyL It is distinct from blanching, 

 as it is also from the white color in orna- 

 mental-leaved plants, of which, however, 

 it may be a modification. Plants may be 

 affected by chlorosis as soon as the cotyl- 

 edons make their appearance. The best 

 culture will not always restore such 

 plants to health. The most promising- 

 remedy is to water them with a very weak 

 solution of sulphate of iron. An example 

 of this condition is to be found in cases 

 where the variegated leaves of Pelargoni- 

 ums, etc., run to pure white without any 

 green. In all such cases death is cer- 

 tain to ensue, unless the leaves again be- 

 come more or less green. 



Chlorospermece. One of the three great di- 

 visions of Algce, characterized by the 

 green color of the spores. See 



CIL 



Chorda Pistittaris. A line of tissue reaching 

 from the stigma down to the cavity of the 

 ovary. 



Chorion. A carpel; also the pulpy matter 

 which fills the interior of a young seed 

 before impregnation. 



Choristophyllous. Separate leaved. 



Chromatidium. The coloring matter of 

 plants. 



Chromism. A preternatural coloring of 

 plants, as that of leaves when they be- 

 come red, etc. 



Chromule. The fluid coloring matter of 

 vegetation. 



Chrysaloideus. Rolled up and folded up at 

 the same time. 



Chrysanthus. Yellow flowered. 



Chryso. In Greek compounds chryso is 

 equivalent to golden yellow. 



Chrysobalanacece. A family of Dicotyledons 

 closely allied to Eosacece, or more gener- 

 ally considered as a tribe of that order 

 taken in its most extended sense. They 

 are distinguished from the other tribes 

 by a frequent irregularity in the stamens, 

 and more especially by their solitary car- 

 pels, with the style always proceeding 

 from the base, and containing two as- 

 cending ovules. The fruit is free, either 

 drupaceous or capsular. There are 

 twelve genera and nearly a hundred 

 known species. 



Chrysochrous. Having a yellow skin. 



Cicatricule. The scar formed by the sepa- 

 ration of a leaf from its stem. 



Cicatrisate, Cicatricose. Marked with scars. 



Cicatrix, Cicatrice. Any kind of scar formed 

 by the separation of one part from an- 

 other. 



Cilice. Somewhat "-stiffish hairs, which 

 form a fringe on the margin of an or- 

 gan, as those on the leaf of Semj)ervivum 

 tectorum.
