236 ANNALS OF SCOTTISH NATURAL HISTORY 



Habenaria Conopsea, Benth., H. bifolia, R. Br. As they still 

 grow on moors in the adjoining parishes so these occurred in 

 Aberdeen in suitable habitats ; but they seem to have become 

 extinct here when Stocket Moor was cultivated. 



H. viridis, R. Br. In short dry pasture on dunes near the Don, 

 never common, and not observed since I saw one there in 

 1902. It is common on Balgownie Links just across the Don. 



Iris Pseudacorus, L. In the early part of last century this was 

 plentiful by the Canal (from near Aberdeen Harbour to 

 Inverurie), and also in sluggish streams by the Links. The 

 Canal was dried and used for a railway before 1860, and altera- 

 tions in the streams led to the disappearance of the Iris. 



Narthedum Ossifragiim, L. This has shared the fate of other 



species formerly plentiful on wet moors and in swamps in 

 Aberdeen, having become extinct locally when Stocket Moor 



was cultivated. 

 AKsma Plantago-aquatica, L. Abundant early last century in 



Gilcomston Dam, this, for some unknown reason, had almost 



disappeared from there before 1900, when the pond was filled 



up. It seems to be extinct locally. 

 Potamogeton heterophyllus, Schreb. This formerly grew in the Canal, 



but disappeared from Aberdeen when the Canal was dried. 

 P. crispus, L. Formerly in the Canal and in Gilcomston Dam. 



It was plentiful in the ponds of Rubislaw Bleach-works, but in 



1908 it perished when the ponds were emptied, in consequence 



of the works being moved elsewhere. 

 Ruppia rostellata, Koch. Discovered in pools by the estuary of the 



Dee in 1849. The estuary was practically done away with 



by the changes made in the channel before 1870. Ruppia 



has been extinct locally for years. 

 Stir pus fluitans, L. " In a pool near Hilton, abundantly " (Harvey, 



before 1830) ; but apparently extinct locally long ago. 

 S. rufiis, Schrad. Formerly on the Old Aberdeen Links, but not 



observed there since 1870 ; possibly choked by sand. 

 Eriophoriim angustifolium, Roth. ) Both must have been common 

 Carex dioica, L. ) in wet places on the moors in 



Aberdeen ; but neither is now known to exist there. 

 C. incurva, Lightf. On Old Aberdeen Links, first noted by Beattie 



in a letter to Smith in 1800. It grew in one or two localities, 



not plentifully ; but appears to have been last observed there 



about 1870. 

 C. vulpina, L. Recorded by Skene "in the Old Town Links" 



before 1770. It has long ceased to grow there, though not 



uncommon on the north shore of the Don.
