^S. Both at the upper end of Tingwall Loch. The latter plant, 

 of which only the var. curvifolius was gathered in 1886, was 

 possibly scarce, as only a single specimen was gathered ; Mr. 

 Bennett speaks confidently as to its name. 



% P. praelongus Wulf. U. Loch of Watlee. S. Tingwall 

 Loch. Abundant in bot h.Can this be the P. lucens of Edmond- 

 ston's Flora, which I have not yet been able to find ? I did not, 

 however, see P. praelongus in the Loch of Cliff, which is one of 

 the stations given by him for lucens. 



% P. pectinatus L. S. Asta and Tingwall Lochs. Unfor- 

 tunately I found only barren examples. Mr. Bennett reports" I 

 suppose will be right no fruit." 



X Zannichelliapolycarpa Nolte (t. Ar. Bennett). U. Loch 

 of Watlee. 



Zostera marina L. The only form seen is the var. 

 angustifolia Fries. 



i Luzula maxima D. C. var. gracilis Rostrup, I remarked 

 last year that this plant was barren on the upper slopes of Saxa 

 Vord Hill, flowering only on the summit. On the Hill of Her- 

 maness, opposite Saxa Vord, the plant occurs in profusion, but I 

 could not find a single flower-stem ; but then, Hermaness only 

 reaches the altitude of 650 feet. I again found the variety flower- 

 ing in the island of Foula, on the Hammerfeld (1000-1100 feet) 

 and the Sneug (c. 1400 feet). 



Juncus triglumis L U. Hill of Colvadale, abundant in wet 

 tony ground at the low elevation of 200-300 feet. The only 

 pther record is Ronas Hill (T. Edmondston). My last visit enabled 

 Eie to see that J. lamprocarpus is much more common than 

 I had supposed. I did not detect J. alpinus, which is likely to 

 occur. On a dwarf form from stony ground by the east side of 

 Tingwall Loch, Dr. Buchenau reports " Planta pusilla, dubia. 

 J. alpinus vel J. lamprocarpus" 



Scirpus pauciflorus appears to be common and generally 

 distributed. 



* Oarex csespitosa L. (Fr.) U. West side of the Loch of 

 Cliff. I did not visit this side of the Loch in 1886, when, how- 

 ever, I walked round the other side without seeing it. I don't 

 suppose that it will prove to be common. Dr. Lange reports 

 " is, as I think, rightly named." 



fulva Good. (C. Hornschuchiana). U. Hill of Colvadale.
