TRIGLOCHIN. POTAMOGETON. 201 



37. Triglochin maritimum. Abundant on marshy spots on 

 all our coast, and at the sides of the Tweed within the influence of 

 the tide. Summer. 



38. T. PALUSTRE, Bogs and marshy places. Aug. — When 

 bruised the plant has a foetid taste and smell, similar to that of 

 Sinapis tenuifolia. "What Mr. Wilson says of the root (Hooker Brit. 

 Fl. p. 153) is in accordance with our own observations. It is diffi- 

 cult to conceive in what way the stigmas are fertilized unless the 

 pollen is discharged by some elastic force of the bursting anthers, for 

 these are so short and so situated as to make a contact between them 

 and the pistils impossible. 



39. Typha latifolia. jacftf iB,acc : ?3IacMjca^<ftJ ICatJtJifsi. 

 Once common, but now its localities are not many. B. In the mill- 

 pond of Grange-burn ; and of Foulden Newtown. Greenwood moss, 

 parish of Coldingham, G. Henderson. In an old marl-pit at Craig's 

 walls ; in a pond near Crumstane ; Lithtillum loch ; in the Eden, 

 &c. It once gave a character, from the extent of surface it covered, 

 to Billymire, where it is scarcely now to be found, for the mire, 

 which was about six miles in length, is converted into arable land. 

 There is an account of the mire in Carr's Coldingham, p. 31. — D. 

 In the low at Goswick ; and in the ditch along the line of the rail- 

 waj' below Haggerston. Jnl3\ — Children carry the flowered plant 

 in processions ; and burn the dried catkins for tapers. 



40. Sparganium ramostjm. Common in ditches and ponds. 

 July, Aug. — This, as well as the Yellow Iris, is called the ^fggt ; 

 a name given with more propriety to some of the larger Carices. 



41. S. SIMPLEX. B. In the stream below Chatterton ford, on the 

 farm of Crunkly, G. Henderson. — R. Pond in Fleurs' park, F. 

 Douglas. — D. Holy Island, at the margin of the lough. — N. In 

 Spindlestone pond. July, Aug. 



42. S. NATANS. Linn. Fl. Lap. 280. B. In thefoss at the head 

 of Coldingham loch : Northfield mill-pond. Old peat pits and ponds 

 on the Lammermuirs, J. Hardy. In the Eden, near Greenknowe,

 of the glen below Heathpool linn. 



43. Arum maculatum. Cucfeoo^pint. B. Grows in great pro- 

 fusion in the woods at Blanerne, and evidently wild, W. Dunlop. 

 Stitchell, F. Douglas. Near Netherbyres, Rev. A. Baird. May. 



44. Lemna trisulca. Ponds, occasionally. 



45. L. MINOR. J^ucfeiurcb. Ponds and ditches, often covering 

 the surface to a large extent, — the " nuiddy vesture of decay." 



46. Potamogeton natans. ^iffetrfll^OTcftf. Ponds and still 

 waters, common. July. — It is a mystery which the herdboys in our 

 muirlands puzzle themselves to explain, that leaves of this plant will 

 not wet. They float flat on the surface of the water, and afl*ord a 

 grateful shelter to many mollusks and insects.
