a good intermediate in all respects ilati/oUa is very scarce in this 

 station). M. Schulze only mentions the hybrid as having been 

 found once in Russia and once near Jena, in Germany ; but Focke 

 (Pflamenmischliiif/e, p. 380) says that it " occurs not uncommonly 

 with the parents, and has been represented as a transition-form, 

 which was supposed to prove the specific identity of the two species." 

 In Britain they very seldom grow together. 



Orchis mascula L. 108. Plentiful on the limestone near Durness, 

 at Ardskinid, and about Betty Hill ; the leaves were always un- 

 spotted. — 0. inccmmta L. 107.''' About Forsinard. 111. Abundant 

 in a swamp at Orgill, Hoy, with very pale flowers ; also seen in two 

 or three spots on Mainland. — 0. latij'olia L. var. brecifolia Reichb. 

 109.-'' Swampy pasture about a mile north of Bilbster Station ; just 

 like the plant of South-east Ireland, the leaves being faintly ring- 

 spotted, and the flowers dingy purple. — 0. latifoUa x maculata ? 

 108. Scullomie. 109. Near Bilbster. 111. Near Stromness. I 

 believe this identification to be correct, but am not quite free from 

 doubt. — O. )iiaculata L. subsp. 0. ericetunini Linton li^V. Bournemouth, 

 p. 208). Evidently very common throughout North Scotland; Mr. 

 Linton has confirmed the name in all the cases submitted to him. 

 We observed it as follows : — 107. Forsinard. 108. Tongue, Scul- 

 lomie, Skerray, Betty Hill. 109. Wick, Bilbster. 111. Hoy and 

 Mainland, passim. 



Habeiiaria conopsca Benth. 108. A form with flesh-coloured 

 blossoms grows about Tongue ; this is probably the G-ijmnadenia 

 conopsea ^ paUidijIora Lange, tlaandh. i den danske Flora. — 

 H. coiwpsea X Orchis )naculata (subsp. ericetorum). 108." Coast- 

 slopes near Scullomie ; discovered by Mr. Shoolbred. We only 

 obtained two specimens ; roughly speaking, they were like H. co- 

 nopsea with a spotted broader lip, rather shortened spur, and paler 

 flowers. I have seen a Kentish specimen in Mr. Hanbury's col- 

 lection, which is very similar, though larger. — H. albida x conopsea. 

 108.-'^ Two specimens in a hilly pasture at Tongue ; one at Scul- 

 lomie. In this neighbourhood the parents are both abundant, and 

 grow together in many places ; but I had great difiiculty in finding 

 the hybrids between them. Probably they are fertilized, as a rule, 

 by difterent insects, as one would expect from the great difterence 

 in the length of the spur. One specimen was just intermediate, 

 another towards albida ; the third, though also an evident hybrid, 

 had the spur hardly at all shorter than in conopsea. I saw one of 

 the West Inverness plants so named by Mr. Rolfe in a fresh state, 

 two or three years ago, which closely resembled these. 



Iris Pseudacorus L. 111. The prevailing form is var. acoriformis 

 (Boreau); we only found the type at the north-west end of Loch 

 Stenness. 



J uncus supinus Moench, var. Kochii Bab. 108. Plentiful about 

 Loch Deerie, near Tongue. 



Lnzula erecta Desv. 106. At 3000 ft. on Ben Wyvis occurs a 

 form which is probably var. sudetica of Lond. Cat. ed, 9 (L. nifjricans 

 DC, L. inultijiora y niyricans Koch); it scarcely differs from plants 

 which I have gathered near the Eggisch-horn, Upper Valais.
