 the bottoms of chairs. In South America 

 it is used for making balsas or boats, and 

 a similar use is referred to in Isaiah, xviii., 

 1, 2. There are 120 known genera and 

 upward of 2,000 species. Cyperus, Papy- 

 rus, Carex, Scirpus, Eriophorum, and 

 Gladium are examples of the order. 



Cyphelia. Collections of gonidia (which 

 see) in the form of cups; a term only 

 used of Lichens.

Cyst. The spore-case of certain Fungi; 

 also the hollow spaces in parenchyma, 

 (which see,) in which the oily matter 

 collects, as in the rind of the Orange. 



Cystidia. Salient cells accompanying the 

 basids or asci (which see) of Fungi ; by 

 some regarded as antherids, (which see.) 



Cystocarpum. A case including a great 

 many spores. The term is confined to Algce. 



Cytoblast. That elementary spherule, de-

 the Thymelaceos, 



Dasycarpos. Hairy-fruited. 



Dasycladece. A small natural order of 

 green-spored Algce, which are either 

 naked or coated with carbonate of lime, 

 and have a one-celled simple or branched

Decandria. The tenth artificial class in the 

 Linnsean system, including certain flow-

 Monoscia, Dicecia, form the orders " De- 

 candria," severally subordinate to those 

 classes. 



Decandrous. Having ten stamens. 



Decaphyllous. Having ten leaves.
