1 P. pusillus. A few immature examples were obtained in 

 Clickhimmin Loch, Lerwick, but in the absence of fruit, Mr. 

 Bennett cannot determine whether referable to the above, or to 

 P. Sturrockii, which the plant somewhat resembles. 



P. pectinatus L. The only stations given by Edmonston 

 are " brackish pools," and it is therefore probable that they all 

 belong to P. filiformis. Still it may possibly occur, as it is re- 

 corded from Orkney on the authority of Dr. Boswell, and Mr. 

 Bennett mentions it from Greenland. 



Orchis latifolia L. U. Near the Loch of Cliff. N. Banks 

 near the sea, Queyfirth near Ollaberry. The only other orchids 



seen were O. maculata (common) and Habenaria viridis 



(Baltasound hills). 



Luzula pilosa Willd. X. Seen only sparingly by Eela 

 Water. 



L. maxima D.C. Here and there. * Var. gracilis, Ros- 

 trup. Confirmed by Dr. Lange. Dr. Buchenau remarks : " A 

 very interesting form, new to me." This distinct variety is abun- 

 dant on the upper slopes of Saxa Vord Hill, Unst, but flowers only 

 on the small plateau which forms the summit. On the lower 

 slopes of the hill neither form was seen, while the typical plant 

 grows on the Burrafirth cliffs, some 700-800 feet below. The two 

 forms, therefore, inhabit different stations, and they do not pass 

 into each other. The var. gracilis is a much more slender and 

 elegant plant, with short (1-3 inches) root leaves; stem only a 

 foot high, slightly drooping ; panicle simple, consisting of a single 

 large terminal head of flowers, surrounded and overtopped by 

 about 2-4 long, filiform, flexuous, or drooping peduncles, each 

 bearing a single (smaller) head of flowers. I have a dwarf state 

 of the type from Little Craigandal (leg. Rev. E. S. Marshall), but 

 it does not approach the variety in any respect, excepting in its 

 low stature. Known elsewhere only from the top of Hesto, 

 Faroes. To me it is the most interesting plant met with. 



L. campestris D.C. Everywhere common. 



+ L. multiflora Lej. Apparently scarce ; occurs (N) near 

 Ronas Voe. 



Juncus COnglomeratus L. Scarce. N. Near Ollaberry. 

 L. Clickhimmin Loch. 



J. acutiflorus Ehrh. I sought this carefully in all the districts 

 visited, but without success.
