GLOSSARY. 



Abjoint. A spore is said to be abjointed when it is developed from the 

 end of a mycehal hypha or from a cell, from which it is first cut 

 off by a septum ; the lower part of the cell is then termed the 

 stalk-cell. 



Abstriction, the separation of a spore by the contraction of the spore- 

 forming hypha below it without the previous production of a 

 septum, as the promycelial spores, Uredine spermatia. 



Acropetal, proceeding in the direction of the apex from below upwards. 



^cidiospore^ those spores of the Uredineas which arise from the pro- 

 mycelium produced by a promycelial spore, in basipetal series. 



A[,cidiuin, the generic name formerly applied to the a^cidiospores. 



Amphigenoiis, growing on both the upper and lower surfaces of the 

 leaves, 



Anasto)nosi7ig, uniting into a network by cross branches.

 cious. 



Base^ the lower end of a spore, that which is nearest its attachment. 



BasidmfH, the cell or hypha from the apex of which spores are 

 abjointed or abstricted. 



Basipetal, proceeding in the direction of the base from above down- 

 wards. 



Bullate, swollen in the form of a blister. 



Capitate, having a head, as when the end of an erect hypha is abruptly 



enlarged in a spherical manner. See Hooded. 

 Carpogottijon, the female cell, which is fertilized by the pollinodium. 

 Circinate, arranged in a circular manner. 

 Clavate, club-shaped. 

 Concatenate, united in a continuous series, like the links of a chain
