that the irritability of the stamens of Berberis is a 

 contrivance for cross-fertilisation rather than for 

 self -fertilisation. 



Of the Polygonacece, he enumerates all the Docks 

 that are found in the district, except the following 

 two, which are very rare and probably not native. 

 Rumex Hydrolapathum has perhaps been introduced 

 both at Woodhall and Corehouse; and R. pulchevy 

 given in our lists on the authority of Patrick as 

 found "between Barncluith and Hamilton Wood," 

 no longer grows there, and is undoubtedly not 

 native in this part of Britain. Of the genus Poly- 

 gonum he gives all the recorded species about 

 Glasgow, except P. minus, which is retained on our 

 lists as occurring on the gravelly banks of the Black 

 Loch. There is a Polygonum common on these 

 banks— a peculiar stunted form of P. Hydropiper 

 which has perhaps been mistaken for P. minus. 



Alisma ranunculoides, given as "rare," is stated- to 

 occur "in the marsh beyond Possil." It has quite 

 disappeared from that station, but is still found 

 abundantly in moist places in the Clyde islands. 



All the species of Epilohium and Erica found here 

 are given. Andromeda poli folia had not then been dis- 

 covered in the neighbourhood. It appears, however, 

 to be undoubtedly native, and probably occurs more 

 frequently than is supposed, as it is not very easily 

 seen, owing to its prostrate habit and the situations 

 in which it grows. 



For the Herb Paris (Paris qicadri folia), he gives 

 two stations: "Banks a little above Calderwood, 

 Ure. Banks of the Cart opposite the mill. Dr. 

 Brown." Hennedy considers this plant "a doubtful 

 native"; but it grows in wild places here and there 

 about Clydesdale, and there is nothing to indicate 

 that it has been introduced. Though it may be 

 called rare in the West of Scotland as a whole, it 

 usually grows abundantly in the stations where it is 

 found. It is in no sense a weed, but an inhabitant 

 of woods. On these grounds I think there can be
