growth-centres which are equally balanced in strength : and this 

 is the simplest form of „fasciation". 



The author compares „fasciation" v/ith the psychological 

 phenomen of „multiple personality" ; and just as in the 

 human being this phenomen causes a complete upset of the 

 normal equilibrium of the organism inducing a reversion to 

 earlier states of consciousness, the same is true of plants under 

 the influenae of „fasciation" which the author regards as a 

 reversion to the dichotomous branching of primitive 

 plants. 



„As to the third c) or physiological sub-division of the 

 etiology of „fasciation": it is probably a pathologica! condition", 

 and is probably due in many, but not all, cases to superabun- 

 dant nutrltion. 



Some of the examples of „fasciation" cited as abnormal 

 phenomena are: the multiple flov/ers of Campamila media 

 and Narcissus poeticus; the large „peloric", terminal flower of 

 Digitalis; twin flower-spikes of Plantago; forked leaves of 

 Lonicera Periclymenum ; strap-shaped inflorescence of Raniin- 

 ciiliis acris and of Celosia ; strap-shaped shoots of Cam- 

 pamila; multiply - forked shoot of Rheiim moorcroftianum ; 

 flattened, dichotomous roots of liedera Helix and Aerides 

 aispum. 



A normal case of „fasciation" is seen in the staminal 

 groups of Hypericaceae, Tiliaceae, Malvaceae.

GOLA, G., Sulla respirazione intramoleculare nelle 



plante palustri. Nota preventiva. (Atti Acc. Reale 



delle Scienze di Torino. Vol. XL. 1905. 7 pp.) 



L'auteur a etudie les graines de Trapa natans et les rhizomes de 

 Niiphar luteum et Nymphaea alba dans la periode de la quiescence et 

 de la germination et a pu constater la presence de i'alcool dans les 

 tissus de reserve. Puisque la vie de ces organes^ submerges dans la 

 vase des marais, a lieu dans des conditions tres defavorables pour la 

 respiration, l'auteur pense que la production d'alcool est l'effet de la 

 respiration anaerobie des tissus naturellement asphyctiques.

Auf den Einfluss, welchen verschiedene Salze und sonstige 

 chemische Substanzen auf die Orientirungsbewegungen der 

 Chlorophyllkörner haben, ist neuerdings von Senn hinge- 

 wiesen. Verf. hat einige ähnliche Versuche angestellt. An ver- 

 schiedenen Meeresalgen lassen sich die Orientirungsbewegungen 

 der Chromatophoren bequem studiren. Verbringt man Dic- 

 tyota- oder /^ßr//«« - Species in Meerwasser erhöhter Con- 

 centration (-j- P/o NaCl), so streben die Chromatophoren den
