APPENDIX II. 



remains straight the miciopyle is directed towards the point 

 of origin of the funicle which is adherent to the side of the 

 ovule. Vide also Ovule. 



Androecium, a collective word for all the stamens in a 

 flower. 



Annulus, a row or gronp of specially thickened cells on 

 the sporangia of many ferns. 



Anterior, the side rembte from the parent axis, the ventral 

 side. The antithesis to posterior. Unless twisting of the 

 pedicel has taken place the arterior sepal or sepals of a 

 flower in an inflorescence will be the lower sepal or sepals, 

 the upper one or ones will be called posterior and the side 

 ones lateral. 



Anther, that part of the stamen which contains the pollen. 

 In Angiosperms {vide Introduction, p. 49) it usually consists 

 of 4 cells, loculi or pollen sacs (microsporanuia), one pair on 

 each side of the anther constituting the "anther-lobes." The 

 cells or loculi often coalesce so that only 2 or even one cell 

 is present in the ripe anther. When the loculi lie their 

 whole length on the relatively broad connective, which then 

 appears as a continuation of the filament, the anther is called 

 adnate. When the filament appears to end at the base of the 

 anther, the latter is called innate. If the anther swings free- 

 ly on the top of the filament, it is called versatile. 



Apetalous, without petals or corolla. 



Apocarpous, see ovary. 



Areola, a space marked off from the rest by some line, 

 nerve, colouration. 



Aril, an envelope which grows up from the base of the 

 seed and more or less completely covers it. It is usually 

 fleshy, e.g., the flesh on the Litcni seed, the red covering on 

 the Kujri (Celastrus panic ulatus) seed. 



Arietate, awned.
