Spore-cell 



OF BOTANICAL TERMS. 



Sporophyl 



restricted sense, proposed by 

 Sachs, the term spore is ap- 

 plied to reproductive bodies 

 which arise either directly or 

 indirectly as the result of fer- 

 tilization, in distinction from 

 gonidium, which is applied to 

 those produced asexually. 

 Spores in this restricted sense 

 are by De Bary termed carpo- 

 spores. See vEcidiospore, 

 Mackospoke, Oospore, Pko- 

 tospore, Teleutospore, Te- 



TRASPORE, UrEDOSPORE, ZOO- 

 SPORE, Zygospore, etc. 



SPORE-CASE, see Sporangium. 



SPORE-CELL, a spore, or a cell 

 which gives rise to a spore. 



SPORE - GROUP, see Compound 

 Spore. 



SPO'RlD, see Sporidium. 



SPORLDESM, see Compound 

 Spore. 



SPORiD'tUM (pi. Sporid'ia), a 

 spore produced upon a pro- 

 mycelium; germ-cell; second- 

 ary spore. Formerly applied 

 to any spore, especially if very 

 small, and still improperly 

 used for Ascospore. 



SPORlF'EROtJS, spore-bearing. 



SPO'ROCARP, a group of spores 

 resulting from fertilization, to- 

 gether with enclosing or attend- 

 ant parts. It is thus the fruc- 

 tification developed from an 

 archicarp or procarp in fungi 

 and Rhodophyceae ; also the 

 sporogonium in mosses. The 

 term is also used for the body 

 enclosing the sporangia in het- 

 erosporous Filicinese. Com- 

 pare Sporogonium. 



SPOROCAR'PlUM, see Sporo- 

 carp. 



SPOROCLA'DlUM, a spore-bear- 

 ing branch, as a stichidium in 

 Floridese. 



SPO'ROCYST, the mother-cell of 

 a spore; sporocyte: occasion- 

 ally also applied to certain 

 sporangia in algse. 



SPO'ROCYTE (Goebel), see Spo- 



ROCYST. 



SPO'RODERM, the coat or cover- 

 ing of a spore, including exo- 

 spore and endospoxe. Com- 

 pare Spermoderm. 



SPORODO'CHltJM (pi. Sporodo'- 

 ■ehia), a spore-bearing or spore- 

 holding apparatus. Applied 

 mainly to the sporiferous 

 mass, including the spores, in 

 the Tuhercularieae. 



SPO'ROGEN, a plant which pro- 

 duces spores; cryptogam. 

 Compare Spermophyte. 



SPO'ROGONE, see Sporogonium. 



SPOROGONIUM (pi. Sporogo'nia). 

 the whole product of the sexual 

 act in the higher c^ptogams; 

 asexual generation; sporo- 

 phore; sporophyte; oophyte. 

 In ferns it is the segment or 

 stage in the life-cycle which 

 we see as the ordinary fern- 

 plant. Compare Prothallus. 



SPO'ROID, spore-like. 



SPO'ROPHORE, a stalk support- 

 ing one or more spores; any 

 spore-bearing apparatus or re- 

 ceptacle, such as a gonidio- 

 phore, sporangiophore, or 

 ascophore; particularly the 

 second or asexual generation 

 in plants having a distinct 

 alternation of generations, 

 such as ferns and mosses 

 (sporogonium). Compare 06- 

 phore. See Simple Sporo- 

 phore, Compound Sporo- 

 phore, and Basidium. 



SPOROPHYL, the same as Spo- 

 rophyll or Sporophyllum and 

 a spelling now in frequent use. 



SPO'ROPHYLL, see Sporophyl- 

 lum.
