Arber, A., On the Structure oftheAndroeciumin Far- 

 nassia and its bearing on the affinities of the aenus. 

 (Ann. Bot. XXVII. p. 491-510. 1 pl. 4 textfig. 1913.) 



The Chief points regarding the androecium oi PaniassiahronghX 

 foward in this paper are as follows: 



1. In the course of a description of the general vascular S3^m- 

 metry of the flower of Parnassia palustris, L., it is shown that the 

 Strands destined for the stamens arise as independent bundles at a 

 Tower level in the receptacle than those destined for the staminodes. 

 The anatomical evidence thus confirms Drude's view (based on 

 developmental grounds) that the nectaries or staminodes of Par- 

 nassia form the inner whorl of the androecium. 



2. In Parjiassia palustris, L., the bündle which traverses the 

 filament is found to be accompanied b}^ centripetal xylem, and there 

 are indications of numerous phloem groups arranged round the 

 xjdem. A similar structure has also been found in the filaments oi 

 P. fimbriata, Banks. It is suggested that these peculiarities of the 

 stamen anatom}^ are due to the presence of vestigial vascular Strands 

 which indicate that each individual stamen of Parnassia is reduced 

 from an ancestral stamen-fascicle, comparable with that occurring in 

 Hypericum. Agnes Arber (Cambridge).
