Hordeum pratense. Not now to be found in the district; some 

 fine specimens occurred to Dr. Neill in the King's Park many years 

 since. 



Junciis ohtusiflorus. Pentland Hills. A curious viviparous variety 

 of J. supinus (J. uliginosus), with half-prostrate stems from a foot to 

 two and a half feet long, occurs with the preceding in the marshes 

 near Collinton. 



Lamium Galeohdolon and rugosum. Dalkeith Park. L. album, 

 Linn., L. maculatum, Linn., and L. rugosum, Ait., appear to be cor- 

 rectly referred by some authors to states of the same species. 



Leontodon palustre. Very abundant on the Pentland Hills and 

 elsewhere near Edinburgh. From several years' observation of this 

 plant in Shetland and elsevrhere, I am inclined to think it is a good 

 species, although now generally sunk into a variety of L. Taraxacum. 

 The characters drawn from the involucre appear to be constant in all 

 the specimens I have seen; and it is by no means improbable that 

 small specimens of L. Taraxacum have been confounded with palus- 

 tre, for I have seen them growing together, and each preserving its 

 distinctive characters. 



Leontodon autumnale. Specimens of a curious variety of this plant 

 having a very stout scape, and covered with a very dense, long, and 

 silky pubescence, occur near Collinton. It is exactly similar to some 

 specimens brought from the Outer Hebrides by Dr. Balfour and Mr. 

 Babington last year, and exhibited at the Botanical Society. 



Polygala vulgaris. I have observed some curious variations in the 

 size of the leaves and sepals, and in the habit, of some Polygalas on 

 Arthur's Seat, Braid, Blackford and Corstorphine hills, &c., and Mr. 

 E. Forbes has registered the same. Whether these differences may 

 prove sufficiently constant to constitute species, I must leave to fu- 

 ture observers. 



Potamogeton. Great numbers of this intricate genus are to be met 

 with around Edinburgh, and, I have little doubt, forms (or species) dif- 

 ferent from those described, but I confess myself perfectly unable to 

 distinguish many of the puzzling fonns ; and I do think that minute 

 differences in the shape of the fruit are not always to be depended on. 



Primula veris, a. Lin. (P. veris of authors), 0. Lin. (P. vulgaris) and 

 y. Lin. (P. elatior of British botanists, P. acaulis, ^. caulescens, Bal- 

 four and Babington). All these forms (for it seems now fully proved 

 that they are no more) are common about Edinburgh. 

 Sedum rejlexum. St. David's, Fife.
