Analog)]: resemblance in certain re- 

 spects. As distinguished from af- 

 Jinity it means resemblance in cer- 

 tain respects only, not in the whole 

 plan of structure. Thus a Ranun- 

 culus is analogous to a Potentilla, 

 but there is no near affinity or re- 

 lationship between the two. And 

 the tendril of a Pea, that of a Smi- 

 lax, and that of the Grape- Vine are 

 analogues, i. e. arc analogous organs, 

 but are not homologues ; for the first 

 answers to a leaf, the second to 

 stipules, and the third to a stem. 

 The spur of a Larkspur (fig. 398) 

 is analogous to one of the five spurs 

 of Columbine {fig. 646), but not 

 homologous with it, for the first is 

 a sepal, and the second a petal.

 veins of animals, and the so-called 

 veins of reticulated leaves, 49, 54.

 299, fig. 529.

Andrdgynons : bearing both stamens and 

 pistils in separate flowers of the 

 , same inflorescence. 



Androphore: a column of united stamens,

 of unequal size. 



Anisosiemonoas : when the number of 



the stamens is different from that 

 of the petals.

 one season, 83. 



Annular : in the form of a ring. 



Annular duels, 46. 



Annulate : marked with rings or circu- 

 , lar transverse lines. 



Annulus : the ring of the spore-case of 

 true Fems, 501, flg. 1289 : that of 

 the mouth of the spore-case or cap- 

 sule of Mosses, 503, fig. 1304. 



AnonaccEe, 382. 



Anophytes (top-growing plants, of tlie 

 same meaningas Acrogens'!), 370, 

 502. 



Anteposition, 248. 



Anterior: as to position in the flow- 

 er, on the side next the bract, 237. 



Anther : the pollen-bearing part of a sta- 

 men, 223, 281. 



Antheridium (plural, antheridia), 334, 

 502. 



Antherlferous : anther-bearing.

 and performs its functions, or the

 like that of the spore-case of Siflach- 

 num and some other Mosses, 503.
