SHOKT NOTES.

may perhaps be a cross with E. tomentosa, though I did not see that 

 near. — Edwaed S. Marshall. 



MiMULus Langsdorffii Donn in Berkshire. — The phiut recorded 

 as M. lutcHs by Eev. W. M. Rogers in this Journal for 1887, p. 342, 

 from Hampstead Norris, in Berkshire, where it was, he says, " a 

 well-established ahen," belongs to the above species; as does the 

 plant from Bognor Marsh, where it exists in very large quantity, 

 and also the plant which I gathered with Lnpatiens bijiora by the 

 Emborne Stream in 1891. In this locality it occurs in both Berk- 

 shire and Hampshire. Probably the Mimnlus luleus of most of our 

 British localities belongs to M. Lam/sdorl/ii, the North American 

 plant. Prof. E. L. Greene, of the Catholic University, Washington, 

 whose interesting paper on M. Lani/sdorjiii in this Journal for 1895, 

 pp. 4-8, suggested to me the examination of our British forms, has 

 confirmed the above name. — G. C. Druge. 



Nanomitrium tenerum Lindb. — On September 6th last I noticed 

 a considerable quantity of this little moss on Ashdown Forest, near 

 Crowborough, Sussex, where it was growing on the mud of a lai'ge 

 shallow pond, which had been left bare by the drought. It was 

 growing in rather dense tufts, and, as described by Philibert [Revue 

 Bryolocjique, 1878, p. 26), it frequently affected the cracks in the 

 mud. N. tencniw [Kphemerum tenerum of Schimper's Synopsis) does 

 not appear to have been recorded from Britain since its original 

 discovery by Mr. Mitten in 1854. Its existence must be somewhat 

 precarious, as on revisiting the locality a week later I found it almost 

 entirely submerged, and there was considerable difficulty in procuring 

 specimens. The absence of the protonema, at least when the plant 

 is mature, gives it an appearance when growing very unlike that of 

 any species of Ephcmerum ; indeed, the protonema is only to be seen 

 on looking for it very closely in the neighbourhood of quite immature 

 plants. Its identity has been confirmed by Mr. H. N, Dixon and by 

 M. Husnot, who kindly sent me French specimens for comparison. 

 — W. E. Nicholson. 



Bartsia Odontites var. littoralis Reichb. in Britain. — Last 

 July I sent Mr. Arthur Bennett fresh specimens of a Bartsia which 

 he named as above. It is the Odontites littoralis Fries. It grows 

 in some quantity, mostly on a shingly shore, on that part of the 

 west coast of Argyllshire included in v.-c. 97. It is at once notice- 

 able by its distinct habit, the stem being simple or with a few 

 straight branches. From a list of twelve European references 

 which Mr. Bennett kindly supplied me I find that it is given as a 

 species in seven cases, a subspecies in two, and a variety in three. 

 Nyman, in Consp. Fl. Eur. and in the Supp., makes it a subspecies 

 of Odontites verna (P.) Reichb. It is found on the coasts of Denmark, 

 Sweden, Norway, S.W. Finland, N. Germany, Holland, and in the 

 saline districts of E. Germany, but has not been previously recorded 

 for this country. — Symers M. Macvicar. 



West Perth Plants. — While we were staying at Callander last 

 summer, my son, F. A. Rogers, brought me a fresh specimen of 

 Lijcopudiuin inundatum that we had gathered on Ben Ledi, a species
