Sea-Thrifts and Sea-Lavenders. By G. C. Dmce (Jotmi. 



Linn. Soc. p. 60 ; April 1901). — The characters and distribution of the 

 Various species are discussed, also the nomenclature. The author 

 suggests the propriety, from a priority point of view, in giving the 

 generic name of Statice to the Thrifts, and Limonium to the Sea- 

 Lavenders. — G. S. S. 



Seeds, Disease in. By G. Massee {Gard. Chron. p. 184; 

 23/3/1901).— Caused by fungi.— G. S. S. 



Seeds, Guaranteed Percentag^e (Bev. Hort. Edge, Jan. 1901).— 



M. Jules Burvenich shows that the usual basis is untrustworthy. The 

 common practice is to sow 100 seeds and to give the percentage of 

 seedlings as that "guaranteed" to buyers. In sowing 2,000 seeds of 

 stock (Matthiola annua), in lots of 100, the percentages varied from 45 to 

 92. The mean of the first ten lots was 72, while the mean of the second 

 was 73 ; so that the true percentage can only be guaranteed from such an 

 extensive experiment as the above. — G. II.

SeneciO Petasites, Dc. Coni])()slt(e, ^lexico (Rev. Hurt. Beige, 

 Jan. 1901). — After some remarks on the differences in the classification of 

 this order by German, English, and French botanists, the author notes 

 that the old term Senecio now includes some ten distinct genera. It was 

 described in Bot. Mag. vol. xxxvii. 1st ser., pi. 1536, when it first flowered 

 in Europe (1812) in Mr. Lambert's garden at Boyton. It is intermediate 

 between S. Tussilaginis and S. prcecox, hence its present name. — G. H.
