TransactioTis. 49 



Plants, interesting as the sole representatives of their genus in 

 Britain, or on account of some special local reason, have been now 

 discovered as follows : — Subularia aquatica (F. R. Coles), in 

 shallow reaches of the Dee below Threave ; Teesdalia nudicauliis, 

 in the Holm Glen by M 'Andrew and at Locharbriggs by Wilson; 

 Alsine verna, mentioned in the Flora as lost since 1864, was re- 

 discovered in Col vend on an excursion of the Society in 1882 ; 

 Orobanche rubra (M 'Andrew), in Col vend; Centuncuhis minimiis 

 (Coles), in Kelton ; Malaxis paludosa (M'Andrew), in Colvend ; 

 and the rare and beautiful grass, Calainagrostis lanceolata, was 

 found undoubtedly native by M'Andrew this year (1884) for the 

 first time for Scotland ; " its most northern station known for 

 certain," says Mr Bennett, "being Cheviotland in N. Northum- 

 berland." 



The Characeo' — not included in the Flora at all — prove to be 

 fairly numerous. In two seasons Mr Coles had found the follow- 

 ing species : — Chara fragilis, Desv., near, if not quite, the typical 

 plant, rarely, in clear pools of the Glengapp water, Tongland ; 

 the variety barbata is the commonest form, being frequent in 

 small streams and sheep drains on the moors in the middle of 

 Kirkcudbright ; var. brachy-phylla, as yet noticed in only one 

 locality, close to the sea on Muckle Ross cliffs ; var. capillacea, 

 local, but very luxuriant in a mill dam in Kelton ; the var. deli- 

 catula is credited by Messrs Groves to Mr M'Andrew — locality 

 unknown. 



Chara polyacantha — This strange and very uncommon plant 

 Mr Coles found in fair quantity in a turbid peaty loch on Culdoch 

 Moor, Kirkcudbright. Nitella opaca, with one or two sub- 

 species, is fairly common in ponds and ditches, while a very 

 beautiful and characteristic form of N. translucens grows in 

 Meiklewood Loch, Tongland. 



Among Filices, Mr Coles records several new stations for 

 Hymeiiophyllum Wilsoni ; Mr Wilson for Cystopteris fragilis ; 

 Mr M'Andrew finds Lastrea spimdosa in the Glenkens woods, 

 and a very striking variety of the common bracken, having the 

 points of each pinna attenuated and then forked, sometimes quin- 

 quefidly; grows in Compstone Wood (Coles, October, 1884), 

 Kirkcudbright. 



Looking at the Flora as a whole, it was pleasant to note so 

 few actual errors, but still there were some plants admitted whose 

 identity, habitat, and distribution were all somewhat lost in
