REPORT FOR 1912. 



289 



Juncus articulatus, L. Waste ground, Askham, v.-c. 69, Aug. 9, 

 1912. Is this gaJl-influence, viviparity, monstrosity, or what? — D. 

 LuMB. This is a frequent condition of the plant in wet places and 

 is, I beheve, due to a gall which Prof. Trail tells me is Livia juncor- 

 um, an insect belonging to the Hemiptera Homoptera."— G. C. Druce. 



Juncus bulbosus, L., var. Kochii, Druce. Woolmer Forest, 

 S. Hants, June 1912. This variety differs from the type not only 

 by its six stamens (a somewhat variable character), which is occasion- 

 ally found in J. bulbosus, but by its erect tufted habit. Dr Hugo 

 Gliick tells me he considers it to be a good variety, as cultivation 

 under changed conditions does not affect its distinguishing character. 

 — G. C. Druce. "Mr Druce doubtless observed this when living as 

 to the characters." — A. Bennett. 



Juncus bulbosus, L., var. [Ref. No. 4943.] Near Omagh, Co. 

 Tyrone, July 1912. — G. C. Druce. "I should name this var. 

 uliginosus, Roth, species sub-su^nnus.'" — A. Bennett. 



Juncus tenuis, Willdenow. Amongst a number of aliens sent me 

 by Mr G. A. Holt, of Sale, near Manchester, were three fine examples 

 of this species. It occurred on the banks of the Bridge water Canal, 

 between Stretford and Sale, but on the Cheshire side of the boundary, 

 October 1912. Along with it was growing a congested variety, 

 18 inches in height. I have asked Mr Holt to procure additional 

 examples of the type, and of the variety, as members will be glad to 

 have this interesting species. — C. Bailey. 



Juncus bufonius, L., forma altissima, mihi. [Ref. No. 16.] Among 

 long grass by pond. Little Herkesley, Essex N., v.-c. 19, July 23, 1912. 

 This interesting form or state is much stouter and taller than any I 

 have ever seen. Hooker gives height, 1 to 8 inches. This varies from 

 9 to 19 inches (circa 30-50 cm.), average 14-15 inches, and I venture to 

 give it the name forma altissima, " Differt a typo in culmis altioribus 

 (circa 30-50 cm.) ramis et ramusculis longioribus attenuatis." Mr Druce 

 has seen this, and says, ' I think only a drawn up condition, but if you 

 have a set for the Club there would be no reason why you should not 

 name it as you suggest.' — G. C. Brown. " This seems to come between 

 the type and the var. foliosus, Buchenau = «/. yb^ioms, Desf., a plant 

 with stems 16 inches high and leaves 8 inches long, a native of Spain 

 and Sardinia." — A. Bennett. " Probably the var. giganteus, Aschers. 

 and Graebn. Stem erect, 3-5 dcm., stouter and less smooth than type." 

 — G. C. Druce. " J. bufonius, L., forma umbrosa, ad var leucanthum. 

 A. and G. accedens " — A. Thellung. " I have still taller examples 

 from near Blackpool, which I submitted to two well-known botanists. 

 Both thought them only 'drawn' examples." — J. A. Wheldon. 

 "Type; altered by the conditions of grov/th." — E. S. Marshall.
