REPORT FOR 1913.

Juncus maritimus Lam., var. Salt marsh, St Mary's, Isles 

 of Scilly, Sept. and Oct. 1913. Leg. J. W. White and 

 E. A. Stideford. I gathered a few specimens early in September 

 when the rush had not reached its full development. In October 

 a correspondent obligingly forwarded a further supply by post. But 

 in the meantime, unfortunately, two great gales had raged at Scilly, 

 sadly buffeting and damaging the stems ; in some instances breaking 

 off the sharp pointed bract, and thus obscuring a main feature of the 

 variety. It will be seen that the lower bract in this plant (when 

 uninjured) always falls short of the inflorescence, and is often not 

 more than a sixth or a quarter its length ; while in the ordinary form 

 of the species the bract resembles a prolongation of the stem to about 

 twice the panicle-length or even more. The Scilly plant has a weak 

 stem, to the height of four feet or so, and a remarkably diffuse 

 decompound panicle. Its abundance is such that the crop was this 

 year mown for the repair of a cottage chatch. So far as I can learn, 

 the only varieties of Juncus maritimus hitherto described are J. 

 rigidus Desf., a Southern plant stated to be " forte rigide," and J. 

 ponticus Stev., from the Taurus This latter, according to Aschers. 

 and Graebn. Syn. Mittel europ. Fl. (kindly quoted to me by Mr C. E. 

 Salmon), has the following characters : — " Unteres Hiillblatt den 

 Bliithenstand weit iiberragend. Kapsel mehr eiformig," and so can 

 have little in common with the plant under notice. — J. W. White. 

 " Prof. Lindman thought my specimen was rather a monstrosity than 

 a variety." — G. C. Druce. "This seems scarcely a valid variety, 

 rather a luxuriant form." — R. S. Adamson. 



Juncus halticus Willd. Southport, Lancashire, Oct. 4, 1913. 

 This is sent as a record. I am afraid the specimens are rather 

 scrappy and were gathered too late in the season. — R. S. Adamson. 

 "Yery interesting; new to England." — G. C. Druce. See Journ. 

 Bot., 1913, p. 350. 



Juncus subfiodulosus Schrank. [Ref. No. 372.] Near coast, 

 Roose, v.-c. 69 b., Sept. 12, 1913. These represent the normal form 

 in N. Lanes. The fruit does not develop. Frequent in lowland 

 marshes and always with J. sylvaticus. So intimately are they 

 associated that I have frequently had to dig up whole tufts to assure 

 myself that the species were separate. Is tlie plant a smirch or near 

 its climatic and latitudinal limits here ^ The fact that there is only 

 one previous record for 69 suggests that Baker's plant differed from 

 this. — W. H. Pearsall. " Yes, rather starved specimens."— R. S. 

 Adamson. " I thought this might be a hybrid at first sight, but on 

 my specimens (Sept. 14, 1913) I find there are fruits, though these are 

 shorter than ordinary, and there is no doubt a greater part of the 

 fruits are abortive. I have noted this before in other species. In 

 looking up good fruited specimens from Carmarthen, there is no doubt
