Lepidium ruderale, L. Abundantly in waste ground near a farm- 

 yard at Keyhaven, S. Hants, July 26, 1912. — J. C. Melvill. 

 " Correct." — J. Cryer and A. Thellung. 



Reseda '? Eastfield, Rugby, July 1912. A casual single plant 



which appeared in my garden here. Tlie plant differs in character 

 from our native Resedae, and has produced no fertile capsules. There 

 are on the sheets a number of specimens left on the plant till Sept. 20 

 on the chance of maturing fruit, but none appeared The first flowers 

 have a very faint odour of mignonette. If a hybrid it is difficult to 

 guess its origin, as neither R. lutea nor R. Luteola occurs within 

 several miles. — L. Gumming, "i?. luteal — J. A. Wheldon and A. 

 Thellung. 



Helianthemum polifoUitm^ Mill. Limestone crags facing sea, 

 Daddy Hole Plain, S. Devon, v.-c. 3, April 17, 1912. — C. Waterfall. 



Viola sylvestris, Kit., (?) var. punctata^ Gregory. Roadside, 

 Wenvoe, v.-c. 41, April 18, 1912. This is a form very well known to me, 

 one which I long supposed to be extreme V. sylvestris, type ; but it 

 appears (by the description) to be this variety. — H. J. Riddelsdell. 

 "Yes, vsLV. punctata of V. silvestris, Lam." — E. S. Gregory. "The 

 variety dates from Hayward's Pocket Book^ 24, 1909." — G. C. Druce. 



Viola Riviniana x sylvestris ("?) Roadside, Monmouth to Staun- 

 ton, v.-c. 35, April 24, 1911. Flower shape is that of Riviniana ; 

 spur-colour that of sylvestris. But the form, though decidedly inter- 

 mediate, may not be the hybrid. Both the 'parents ' were present. — 

 H. J. Riddelsdell. "Possibly; though nearest to V. Riviriiana.^^ — 

 E. S. Gregory. " I cannot see any trace of V. sylvestris in my two 

 examples ; the foliage, calyx-appendages, and spur are all character- 

 istic of V. Riviniana"— 'Et. S. Marshall. 



Viola Riviniana, Reichb., var. Jtavicornis, Forster. Damp turf, 

 Tiptree Heath, Essex N., v.-c. 19, May 9, 1912. Identified as above 

 by Dr Gilbert (of Tunbridge Wells) in 1910.— G. C. Brown. " No ; 

 the shape of leaves and stipules only sparsely fringed, point to V. 

 canina^ var. ericetorum ( V.flavicornis, Smith, in part)." — E. S. Gregory. 



V. Riviniana, Reichb., forma minor. St. Lythan's Down, v.-c. 41, 

 April 19, 1912.— H. J. Riddelsdell. " Yes."— E. S. Gregory. 

 " Right, I think ; the rather large flowers are against its being var. 

 diver sa, Gregory." — E. S. Marshall. 



Viola canina, L. Wood at 400 feet, Tidenham, v.-c. 34, May 9, 

 1912. It also grows on the chase, in open ground, at 600 feet. —
