and colour o£ the ripe berry, which, however, is plum-violet rather 

 than dark blue. The hybrid fruits much less freely than either 

 parent, and its flowers ai-e roughly intermediate in size and shape ; it 

 would be of interest to know which is the male and which the female 

 parent. In the paper mentioned above, Mr. Brown states that the 

 discoverer of the plant sent specimens to Darwin, who suggested that 

 the seeds would show infertility. So far as we are aware, no one has 

 since investigated this point : we have collected and distributed a 

 considerable amount of seed for experimental sowing, and hope to 

 make a definite statement at some future date. 



SHORT NOTES, 



Uthicularia. The size of the species of this genus as given in 

 our books is far too small. Syme (Eng. Bot. ed. 3, vii. 126, 1867) 

 gives for U. vulgaris " 6-18 inches long," and for Z7. intermedia 

 *' 6 inches." Messrs. Burrell & Clarke (Trans. Norf. & Nor. Nat. 

 Soc. ix. 266, 1911) give U. vulgaris as occm-ring on East Buston 

 Common " 6 feet long " and on Foulden Common Avith flower-stalks 

 *' 15 inches long." I have Z7. major 24 Inches long gathered by the 

 late George Nicholson at Staines, Middlesex. XT. minor often occurs 

 in Norfolk 9-10 inches and U. intet^media 12-15 inches long. —

 (Krit. Fl. Schlesv.- Hoist, ii. 103 (1890) ; B.. inundatum ^SiV.fluitans 

 Fries, Bot. Not. et Mant. iii. 182 (1842), Herb. Norm. 8, n. 18 

 (1842) — " caule elongato ramoso fluitante, foliis omnibus capillaceo- 

 multifidis." Mr. A. H. Evans sends this from near Holyhead, 

 Anglesea, " growing in water 3 feet deep, and flowering under water." 

 The leaves on the lower part of the stem have the common stalk 

 shortened to about half an inch, thence the leaves are dissected like a 

 Batrachian Banunculus, and the rest of the stalk is suppressed. —

JuNCUS PTGMiKUS Bicli. In Davej^'s Flora of Cornwall (1909) 

 this interesting Bush is described as occurring in several localities, 

 near together, in the Lizard district ; I am not aAvare that it has 

 been reported elsewhere. In June of this j^ear I found it in con- 

 siderable quantity in damp places on cliffs about two miles west of 

 St. Ives, Cornwall, in the Land's End District (District 8), perhaps 

 25 miles from the Lizard locality. — H. Downes.
