Germination of Charophyllum Bulbosum. By Professor 

 KIRSCHLEGER. Flora, 1845, 401. The seeds had ger- 

 minated in spring, with two cotyledons ; however, no 

 bud existed between the cotyledons ; but at the base of 

 the plumule a tuber was developed, which, during the 

 same year, bore radical leaves, and in the following 

 year flowers and fruit. This circumstance was not un- 

 known, having been long since observed in Bunium bulbo- 

 castanum. 



An account of some Seeds buried in a Sandpit, which 

 germinated. By WILLIAM KEMP. Annals of Nat. Hist, 

 v, 13, p. 89. The layer of sand which contained the seeds 

 was nearly 25 feet (see Ann. Nat. Hist.) below the sur- 

 face. They germinated, and were found to be those of 

 Polygonum Convolvulus, and a variety of Atriplex patula, 

 with Eumex acetosella, an Atriplex, &c., only common 

 British plants. The author considers them to be of an 

 immense age, and supposes that the Tweed had flowed 

 through the valley, and deposited the seeds, before a large 

 vein of trap-rock passed through it. Probably a more 

 accurate examination would somewhat diminish the time. 



Wahlberg's remarks in the Report of the Swedish 

 Academy are more reasonable. (Vide Mora, 1845, p. 61.) 

 He sowed the seeds of several plants, foreign and Swedish. 

 The place was covered with building materials for many 

 years, and when these were removed and the soil dug up, 

 several plants sprung up which had previously flowered 

 there. 



Periods of flowering and ripening of several wild 

 and cultivated plants, , which were observed in 1843, for 

 the purpose of forming a scale of the development of 

 plants in various parts of the duchy of Nassau, in the 

 Annual Reports of the Society for the promotion of 

 Natural Science in the Duchy of Nassau, by Dr. K. 

 THOM^E. Wiesbaden, 1844. The plants were: Eibes 

 ruhrum and Grossularia, Fragaria vesca, Rosa canina, 

 Primula veris et officinalis, Sambucus nigra, Primus
