 of course, not impossible that some of the forms named above

A NEW VARIETY OF STACHYS SYLVATICA L. 



By E. M. Cutting, M.A., F.L.S. 



- In 1919 a few clumps of plants were found, in the village of 

 Shoreham, in Kent, that differed from the ordinary Stachys sylvatica 

 in a few points only. There were specimens of the ordinary type in 

 their vicinity, but no other species of Stachys; nor did the variants 

 incline, in any of their characters, towards the allied species. This 

 makes it very unlikely that the new form should be a hybrid, and 

 indeed it does not agree with the descriptions that have been given 

 for any of the Stachys hybrids. In 1920 the same spot was visited 

 and fewer of these plants were found, the evidence, as far as it went, 

 seeming to point to crossing between the new variety and the ordinary 

 specific form, with consequent swamping of the new plant. 1 have 

 succeeded in growing some of these and also some of the supposed 

 hybrids, and hope to be able sometime to give a further description of 

 them. Meanwhile, I have thought it worth while to record the 

 occurrence of the plant and to describe shortly the few points in 

 which it differs from the type-species. The most striking feature is 

 the absence or almost complete loss of the purplish streaks that 

 are so characteristic of the lower lip of the corolla of Stachys syl- 

 vatica. It has been pointed out to me by Dr. Salisbury, who kindly 

 examined fresh and pressed specimens, that there were traces of two 

 of the longitudinal marks. Since hearing from him, I have had the 

 opportunity of examining fresh flowers and find that these are con- 

 tinuous with the coloured margin of the lower lip, and show but 

 faintly. The corolla is of a brighter shade than that of the darkest 

 [lowers of the typical plant, but the intensity of colour differs much 

 in the latter. At first sight the colour also seems to be of a richer 

 tone, but this is probably due to a contrast with the large whitish 

 spot on the lower lip. This area has a pruinose appearance owing to 

 the presence of a number of peculiar hairs covered with knobs ; these 

 and the coloured undertissue modify considerably what would other-
