Note on the TVJiite-Jlowered variety of Orchis latifolia, Sfc. 

 By Charles Prentice, Esq. 



In the * Phy tologist ' of this month there is a note fi-om Mr. Ogil- 

 vie, concerning the occurrence of the white-flowered variety of Orchis 

 latifolia in the Highlands of Scotland. This variety is far from being 

 so rare as he seems to consider it, for it occurs in considerable abun- 

 dance on Roydon Green, near Diss, in Suffolk, together with the 

 usual reddish, pink-coloured plant, though the white variety is rather 

 the more fi-equent of the two. Lipavis Loeselii, Utricularia niinor 

 and Cladium Mariscus are found on the same fen. 



With regard to Mr. Townsend's remarks on the occurrence of 

 Phleum arenarium inland, I can state from personal observation it 

 grows sparingly on Waltham Lyng, near Diss, in Suffolk. I once 

 gathered a single plant of Littorella lacustris, on a wet part of the 

 same heath, which is singularly barren and stony. I need not say it 

 is quite inland. Carex arenaria does not occur there. Liparis Loe- 

 selii is, I fear, fast being extirpated, as it is sure to be gathered with 

 its roots, which, from the sandy, soft, boggy soil in which they grow 

 are easily eradicated. The destruction of Gamlingay Heath has 

 also taken away one of the best localities for this curious and rare 

 plant, as well as for several others.

[I do not consider the white variety of Orchis latifolia as a plant 

 of uncommon occurrence. I have seen it plentifully near Loch Fyne, 

 in Scotland, and near the Black Mountain, in Wales, besides occa- 

 sionally in other localities. The white varieties of some Orchideaj
