satisfactorily represent this rare Labiate in any herbarium. Surely it 

 would have been wiser, in view of the plant's scarcity, to have allowed 

 such roots to remain undisturbed until they produced acceptable 

 specimens later on." 



Mr. Marshall sends from his garden at West Monkton an unnamed 

 Betula, with the following note : — '* Root from boggy, peaty ground, 

 at about 2800 feet, descending from the Lochnagar tableland towards 

 the Dhu Loch, S. Aberdeen, v.c. 92, July 1906. In the wild state 

 this was a very small shrub, only a few inches high, with hairy 

 leaves, strongly suggesting a cross between JB. nana and B. puhescens 

 (I have never found the latter so high up). It has now grown into 

 a good-sized bush, nearly six feet in height, but has never produced 

 catkins. The leaf -outline has become much less crenate, and it mio-ht 

 well pass for B. puhescens, var. microphylla ; but I still think that 

 it may be a per-puhescens form of X B. alpestris Fr." 



The notes on Orchis relate to specimens collected at Mildenhall, 

 W. Suffolk, by Mr. W. C. Barton, who writes : '* All [are] from one 

 marshy field, where, in addition to those now sent, O. Fuchsii Druce 

 {inaculata auctt.) occurred. The plants were sorted fresh, when the 

 characters were easily distinguished. All forms varied much in size 

 and in width of leaf (a character which I believe to be of no dia- 

 gnostic value), and it is noticeable that all were gathered on the same 

 day." They include a form of O. incarnata, which, according to 

 Mr. Pugsley, " seems to show a somewhat greater foliar development 

 and slightly broader lip than obtains in the extreme form of O. incar- 

 nata occurring in the Scotch Highlands, the flowers of which, in my 

 experience, may be either purple or salmon-pink in colour in different 

 localities" : a plant named by Mr. Barton, who is "convinced it is 

 a good species," O. prcetermissa Druce, of which Mr. Pugsle}^ says : 

 '* This appears to be the plant which I understand to be O. prcster- 

 missa Druce, and if so it is, I believe, the common marsh Orchis of 

 the south of England, and the only form I have seen in Surre3^ 

 Though its flowers are usually purple, they are occasionally flesh- 

 coloured, and there were formerly a few plants with these pale 

 flowers among the common purple-flowered form on Wimbledon 

 Common": and a hybrid — O. Fuchsii X prcetermissa — the leaves of 

 which " when fresh were distinctly spotted," on which Mr. Pugsley 

 writes : — " If the leaves of this were spotted, and the plant was 

 growing with the reputed parents, the identification is probably'- 

 correct. The spur, however, simulates that of 0. latifolia, and it 

 seems possible that the plant belongs to a form with narrow, spotted 

 leaves, occurring in the south of England, which has been referred to 

 that species, but which may really be the above-mentioned hybrid. 

 But in the example sent I can see no traces of the dark variegation 

 of the lip which characterises most, if not all, the forms of O. lati- 

 foliar 



Mr. C. E. Salmon has the following note on Alopecurus geni- 

 culatus Xpratensis=A. hyhridus Wimm. : — " This grass attracted the 

 attention of Mr. L. B. Hall and myself when botanizing along the 

 side of one of the numerous dykes of Amberley Wild Brooks. It was 

 growing in plenty in close proximity to A. geniculatus, and formed
