 cellular spaces through the stomata of submerged organs is 

 prevented.) 



Der Spaltoffnungsapparat im Lichte der Phylogenie. 

 xv + 196 pp., 4 pis. and 4 text-figs. Jena, 1905. 

 [Pp. 83-87 deal with the stomates of water plants and form

On the Buoyancy of the Seeds of some Britannic 

 Plants. Sci. Proc. Royal Dublin Soc., N.S., Vol. xiv.

 Annals of Bot. Vol. xxv. 1911, pp. 253-267, 2 pis. 

 and 7 text-figs. 



(A general account of H. palustris and H. inflata. The author 

 shows that the mature plant of H. palustris is not rootless as 

 generally supposed. Traces of polystely occur at the base of 

 the inflorescence axis in both species.) 



The Flora of the Cropstone Reservoir. Trans. Leic. 

 Lit. and Phil. Soc. Vol. in. 1895, pp. 430-442.

 the genus.) 



Ueber die Entstehung der Kalkincrustationen an 

 Siisswasserpflanzen. Pringsheim's Jahrb. f . wiss. Bot. 

 Bd. xix. 1888, pp. 138-154. 



(The author shows experimentally that the chalk incrustation 

 on the surface of so many fresh-water plants is due to the 

 abstraction, during the process of assimilation, of CC>2 which 

 has held the calcium carbonate in solution.)

 pp. 512-517, 2 text-figs. 



(The author's anatomical study of the seedling leads him to 

 the conclusion that the primary root is entirely unrepresented. 

 The anatomy of the hypocotyl is modified by the insertion of 

 numerous adventitious roots which are localised on the same 

 side of the axis as the large cotyledon.)
