nation it would be necessary to know wbether the plant grows in 

 company with its putative parents. Mr. Jackson has promised to 

 investigate this point, but I may mention that 1 have seen C. (jer- 

 manica Willd. from the locality. (See Ilcport for 1892, p. 379.) —

Potamor/eton spcmjanUfulixis Laestad. River Maam, Co. Galway, 

 5th July, 1895. — W. A. Shoolbeed. " I doubt much this being the 

 true plant of Laestadius, notwithstanding the late Prof. Babington's 

 opinion that it was so (cf. Journ. Bat. 1872, 228). My specimens, 

 gathered by Laestadius himself, differ in many points ; and I think 

 we must, anyhow at present, use Syme's name — P. Kirkii — until a 

 careful study of the plants in .situ is made. In his ' Loca parallela 

 plant.,' in a note on sjutrf/anHfolius, Laestadius observes, ' Sparr/anio 

 natanti e longinquo simillimus. Folia natantia sfepe desuut, tumque 

 nemo sane divinaret, tarn propinquum esse P. natanti, ut dubium 

 sit an ex illo tuto separari possit' (p. 242 (1839))." — Ar. Bennett. 

 "This resembles the Scandinavian plant in the submerged leaves, 

 but differs in the branched stem and in the shape and areolation of 

 the floating leaves; it might be placed under P.jixdtans as a variety, 

 but I would prefer to name it P. Kirkii Syme. Possibly it may be 

 poli/r/oni/olius x natans.'" — A. Fryer. 



Potamogeton nndulatus Wolf. = P. perfoUatus X crispiis. Sixmile 

 River, above Templepatrick, Co. Antrim, 10th Aug. 1894. Grows 

 in dense masses in the deeper parts of the river, with abundant 

 ffuiting spikes, but no fertile drupes. In shallows of a tributary 

 stream it creeps amongst stones, but in that situation produces only 

 leaves. — S. A. Stewart. "There is a considerable degree of un- 

 certainty as to the precise form which Wolfgang described as 

 P. undulatiis. On such evidence as I have been able to obtain it 

 seems probable that original specimens gathered and named by him 

 are in part P. pralonyns x crispus, and in part P. crispus x per- 

 foUatus. M. J. Baagoe has examined the typical specimens in the 

 St. Petersburg Herbarium, and assures me that this is crispus x 

 praloncjus ; a specimen in my herbarium, gathered by Wolfgang, 

 seems to me to be the same as the Stirling plant collected by Messrs. 

 Bidston and Stirling, which is certainly crispus x perfoUatus. Mr. 

 Baggoe inclines to think that none of our British specimens equal 

 Woltgang's plant, and has sent me drawings of stem-sections of the 

 type and of my var. Cooperi, and of the supposed parents of the two 

 forms, which strongly support his views. I think Mr. Stewart's 

 plant is equal to my var. Cooperi, and perhaps had better be named 

 Potamotjeton X Cooperi = crispus X pierfoUatus." — A. Fryer. 



Alnpecurus vtriculatiis Pars. Meadow, near Oxford, 13th July, 

 1895. This grass was growing in fair quantity in a meadow in the 

 neighbourhood of Oxford, in May, 1895. It was not an isolated 

 patch, but thinly scattered about over a space of about 150 yards, 

 and apparently well established. On inquiry from the farmer who 

 occupies the land it proved that he had used a great deal of foreign 

 hay in the year 1893, when the English hay-crop almost entirely 

 failed owing to the drought. The seeds which became separated in
