to by Mr Druce in the New Phyt. x., Nos. 9 and 10, p. 318.— W. G. 

 Travis. " This seems the same form which M. Malinvaud calls 

 ' M. aquatica var. hirsuta, minor monocepliala, forma reducta.' See 

 Report 1897, p. 561." — C. E. Salmon. "Only, I believe, a depauperate 

 state, due to situation." — E.S.Marshall. "I put this under var. 

 minor Sole." — G. C. Druce. 



Mentha. From a cottage garden, Prestbury, N.-E. Glos., v.-c. 33, 

 Sept. 20 and 23, 1913.— C. Bailey. "This has the very small 

 corolla of x M. rubra, var. Wirtgeniana F. Schultz = M. verticillata x 

 viridis Rouy. I consider this to be x M. cardiaca Baker ; it agrees 

 very well with my specimens of that from Warwick, Surrey, and 

 Bucks." — Ed. " x gentilis L. {M. arvensis x spicata)." — A. Thel- 



LUNG. 



Mentha rubra Sm.? Marsh at edge of reservoir, nearly dry, Bare- 

 law, Midlothian, Aug. 26, 1913. — R. S. Adamson. " Certainly not 

 rubra. This is a sativa (aquatica x arvensis) form, and nearest, I 

 think, to that named paludosa Sole." — C. E. Salmon. "I think 

 it comes near M. rubra, one of the parents is doubtless the hairy form 

 of 31. aquatica, it is a new form to me."^ — G. C. Druce. "T should 

 have thought much too hairy for rubra. ; much nearer M. sativa L. 

 {M. aquatica x arvensis), var. paludosa Sole in my opinion." — Ed. 



Origanum vulgar e, var. albiflorum Lej. Craig Breidden, .Mont- 

 gomery, N. Wales, Aug. 1913. — J. C. Melvill. 



Origanum vulgar e L., c. albijiorum Lej. Dunnichen Hill, Forfar, 

 v.-c. 90, Aug. 17, 1913. This white-flowered form grows here and 

 there on the Old Red Sandstone of Forfarshire. — R. and M. Corstor- 

 phine. " Bentham in DC. Prod, says of 0. vulgare : — ' corolla . . . 

 purpurascens vel rarius alba.' This Forfar plant seems, however, 

 something more than a white-flowered state of 0. vulgare. The bracts 

 and calyx are of a clear green instead of purple, and the whole plant 

 lighter in colour ; it seems to be the sub-var. pallescens of Coss. and 

 Germ. {Fl. Env. Paris, 1861), and var. albiflorum Schur. (Enum. pi. 

 Transs. 1866)." — C. E. Salmon. " Surely not worth a varietal name." 

 - — E. S. Marshall. " The white-flowered plant proves constant in 

 culture." — G. C. Druce. 



Clinojjodium vulgare formal Chalk grassland at edge of wood, 

 Ditcham Park, Hants, Sept. 21, 1913.— R. S. Adamson. "This 

 appears to be the var. diminutum Eng. Simon in Bull. Soc. Bot. Deux- 

 Sevres 207, 1903. Plants reduit dans toutes les parties; verticilles 

 pauciflores = Satureia Cli7iopodium Caruel, var. diminuta Rouy FL 

 Fr. xi., 337, 1909."— G. C. Druce.
