spicuous by its absence. Students desiring further useful notes on 

 this genus will find helpful matter in Mr. White's admirable Flore 

 of Bristol (under Pyrus) ; in the Flore de la Suisse, by Schinz and 

 Keller; and, to go back to 1853, in the excellent Flore die Jura, 

 by Godet. Indeed, my excuse for this note is to draw the atten- 

 tion of British botanists to this little-known book, containing 

 860 pp. of good descriptions in French of all the families, genera, 

 and species of Phanerogams and Ferns found in the French and 

 Swiss Jura. A second edition with supplement w^as published in 

 two volumes in 1869. Like Mr. White's volume, the Flore du 

 Jura contains many illuminating notes and observations. Godot's 

 work preceded in 1851 by an "Enumeration"; in the finished 

 work w^e are told that much additional help was supplied by the 

 English botanist E. J. Shuttleworth. — H. S. Thompson. 



Ruscus ACULEATUS L. — This species is usually described as 

 dioecious. Hooker says of the genus, " subdioecious shrubs." A 

 note in Journ. Bot. (1870, 10) records male and female flowers on 

 some plants. In my neighbourhood the species is frequent, and 

 plentiful in some places, apparently always female. Berries are 

 scarce, and, so far, I have failed to discover either male plants or 

 male organs on female plants. Wishing to obtain a male plant to 

 fertilise the luxuriant bushes in my shrubbery, I sowed seeds in 

 the spring of 1912, but no seedling developed till the spring 

 of 1915. Do the seeds require heat to germinate? The flowering 

 period is described by Syme, E. B., as early spring. Hooker says 

 February to April. I can find flowers expanded every December, 

 and have seen them in November when I have looked for them. 

 Mr. Clement Reid told me several years ago that he had seen the 

 flowers out in November year after year. What other British 

 species bears flowers and the fruit of the previous season at the 

 same time? — E. F. Linton. 



Centaueium maritimum in Corfu. — This pretty species grew 

 on a knoll near Camone in April, 1914, with other interesting 

 species, including Linum jpuhescens Russ., Orchis co7nimUata Tod., 

 Serapias occultata Gay, and S. Lingua L. It is not included for 

 Corfu in Halacsy's Flora, but is given on the authority of Fieri 

 from Ipso in that island in the Supplement. — G. Claridge Druce.
