CCM/AOS

Certificate of Cultural Merit Awarded to the exhibitor of a well-flowered specimen plant of robust health. The plant must score more between 80 and 89 points inclusive on a 100-point scale.

CHC

Coconut Husk Chips. Washed chips made from coconut husks, used as a potting medium. CHC hold water and release it evenly as the mix dries out, similar to a sponge. Due to processing they may contain high amounts of salt which should be leached out with several soakings and rinsing. Also see Coir.

CHM/AOS

Certificate of Horticultural Merit Awarded to a well-grown and well-flowered species or natural hybrid with characteristics that contribute to the horticultural aspects of orchidology, such as aesthetic appeal. This award is granted provisionally and filed with the judging center Chair pending taxonomic verification supplied by the exhibitor.

CITES

Convention on International Trade in Endangered Species. The multinational agreement that lists which plant and animal Species are considered endangered and the rules by which their trade is governed. http://www.cites.org/

Clone

(KLOHN) The vegetative propagation of an individual plant, produced through such methods as Division, Meristem propagation, Keiki, stem propagation, etc. Individuals will be genetically identical.

Coir

(Koi-er) Coir is the term given to a range of natural products manufactured from coconut husks. It is used a potting media or supplement in a potting mix. Various forms exist, including coir fiber, coir chips and chunks. It is a renewable resource and a natural by-product of the brown fiber industry of tropical countries such as India, Indonesia, Philippines and Sri Lanka. Also see CHC

Colchicine

(KOHL-chuh-seen) A toxic natural product and secondary metabolite, originally extracted from plants of the genus Colchicum (autumn crocus, Colchicum autumnale, also known as "meadow saffron"). Used for inducing polyploidy in plant cells during cellular division by inhibiting chromosome segregation during meiosis; half the resulting gametes therefore contain no chromosomes, while the other half contain double the usual number of chromosomes (i.e., diploid instead of haploid as gametes usually are), and lead to embryos with double the usual number of chromosomes (i.e. tetraploid instead of diploid). While this would be fatal in animal cells, in plant cells it is usually well tolerated, frquently resulting in plants which are larger, hardier, faster growing, and in general more desirable than the normally diploid parents. For this reason, this type of genetic manipulation is frequently used in breeding plants commercially. When a tetraploid plant is crossed with a diploid plant, the triploid offspring will be sterile.

A color type often used to describe paphiopedilum orchids which display richly colored flowers of white, green and burgundy.

The progeny which result when primary hybrids are crossed with different species or hybrids.

Crown

The central part of the leaves, from which new growth arises. Typically the growing point of an orchid with monopodial growth habit.

Cultivar

A plant variety maintained in cultivation by vegetative propagation. The word “cultivar” derives from “cultivated variety.” Cultivars have particular, desirable qualities that distinguish them from common, unselected seedlings. A Cultivar name is enclosed in single quotation marks. Example: C. percivaliana ‘Summit’ FCC/AOS - 'Summit' is the cultivar name. Blc. Mem. Crispin Rosales 'Carmela' AM/AOS - 'Carmela' is the cultivar name.

Cuticle

The thick, waxy, protective covering secreted by leaves that reduces the rate of water loss through Transpiration.

Dimorphic

As in Dimorphic flowers. Having male and female flowers produced by the same orchid plant. Dimorphic flowers may enhance pollination by attracting pollinators at different times of the day and night or cause an adversion to only the male flowers once pollinia has been deposited on the pollinator.

Diploid

Cells have two copies of each chromosome.

Division

(di-VIZH-un) Propagation by means of separating the root system or Rhizome into parts. Ths technique of propagating plants by cutting or breaking apart the pseudobulbs or stems at the rhizome; a single propagation derived in that manner.

Epiphyte

A plant that grows above the ground attached to a branch or tree trunk; it derives no nutrients from its host, instead absorbing nutrients from the moisture and debris that collect on them.

Epseudobulbous

(e-soo-do-BUL-bus) Without pseudobulbs.
