Veil'. tUDiidula Laestad. 108. Plentiful and luxuriant in the marshes 

 near Loch Naver, Altnaharra. — C. capillaris L. 107. Near the 

 summit of Ben Griam More. 108. Limestone hills east of Durness; 

 on the dolomite near Hielam Ferry, at sea-level ; Coalbackie, and 

 other places on the coast near Tongue. — C. binervls x rifjida, 

 n.hybr. 106. South-east corrie of Ben Wyvis, with the parents, 

 at 2700 ft. or more ; a good-sized patch, but only two spikes were 

 present. Root- and stem-characters almost entirely rigida ; leaves 

 much longer, but similar in texture. Inflorescence half-way between 

 the two, quite barren ; the lowest spikelet in my specimen has a 

 peduncle 1 in. long, and is placed 2 in. below the others, which are 

 contiguous, as in rvjida. A few minutes before, Mr. Crawford had 

 discovered (at nearly 3000 ft.) an extraordinary sedge, of which I 

 have no specimen, which resembled C. ritjida in habit, with the in- 

 florescence of C. curta ; we did not observe the latter species, but 

 could feel no doubt about its being the offspring of these two. 

 Roots were sent to the Royal Botanic Garden, Edinburgh ; so that 

 further light on both plants may be expected. — C. Hornschucliiana 

 Hoppe X Oederi var. uedocarpa And. (C. sterilis Syme ; / C. fidva 

 Good.). 108. Marshes, Altnaharra. 111. Stenness, Mainland. 

 All my gatherings of this group were accepted by Herr Kiikenthal 

 as correct. — Cjiaca L. var. lepidocarpa (Tausch.i. Frequent in the 

 north, where I have never found typical //«<•«. 108. About Tongue, 

 in several stations ; Betty Hill. 109. Swampy ground near the 

 Wick River. 111. Linksness, and other places in the north part 

 of Hoy ; common. In the four specified localities it grew with 

 C. Hornschuchiana, and produced perfectly barren hybrids. C. 

 Hornschiichiana X lepidocarpa is mentioned by Dr. Focke in Beo- 

 bachtunfjen an Miscldingspjianzen (1892) as, in cultivation, never 

 expanding its male flowers; which I have found to be normally 

 the case with hybrids of C. HonischucJiiaiia. — C. Oederi Retz. 107. 

 By the loch lying at the northern base of Ben Griam More. 111. 

 South shore of Loch Stenness, easl of the hotel. 



Agrodis canina L. var. scotica Hackel. 106. Ben Wyvis, ap- 

 parently scarce. 



Deschampsia discolor R. & S. 108. West end of Loch Modsarie, 

 in small quantity. 



Avena pubesce^is Hiids. 111. Cliffs, Waulkmill Bay. — A. strigosa 

 Schreb. 108. A weed in oatfields at Tongue ; as is A. fatita L. at 

 Coalbackie. 



Koeleria cristata Pers. 111. Loch of Skaill. 



Briza media L. 109. Left bank of the Thurso River, near the 

 foot-bridge, in very small quantity ; one of the rarest northern 

 grasses. 



Glyceria plicata Fr. 111." By several small ponds between 

 Stromness and Sandwick, together with G. jiuitans R. Br. and 

 G. pedicellata Towns. By Mr. Townsend's kind permission I give 

 the following extract from a letter of his : — " I think you are right 

 in supposing G. pedicellata a hybrid. I have never found it in seed, 

 though searched for for innumerable years. The anthers never 

 expand, and the cells are divergent and yellow ; those of /iiiitans
