holosteoides ; but I see no resemblance to the plant so named by Fries. 

 He also found on the White Horse downs a form of Gentiana, which he 

 at first thought might be G. campestris, but was inclined afterwards to 

 put under G. germanica : the plant is, I think, distinct from both. 

 Dr. Trimen's herbarium of British plants is now incorporated in that 

 of the British Museum. Dr. Trimen's premature death occurred 

 in 1896. See the memoir in Journ. Bot. (1896) 489. 



Mr. J. Cosmo Melvill, the author of a Flora of Harroic, contributed Melvill. 

 a considerable number of notes of plants observed in the neighbour- 

 hood of Wargrave to Mr. Britten's list. We owe to him the following 

 additions to our county flora : Filago cqnculata, Barliarea praecox, Ruhiis 

 villicaulis, R. ' rudis ' {R. echinatus), R. Koehleri, var. pallidus ; and to him, 

 conjointly with other observers, Melilotus arvensis, Rammcidus tricho- 

 2)hynus, and Delphmhtm AJacis. From his MSS, kindly lent me recently 

 I also find that he discovered Carex elongata. 



Maemaduke Alexander Lawson, formerly Professor of Botany in Lawson, 

 the University of Oxfoi'd, was born at Seaton Carew, in co. Durham, M. A. 

 on Jan. 20, 1840 ; he took his M.A. from Trinity College, Cambi'idge, 

 in 1864, and was appointed to the Professorship at Oxford in 1868. 

 At this time he took some interest in British plants, and in conjunc- 

 tion with the Kev. H. G. Fox made a list of the Plants of Skye (see 

 Journ. Bot. (1869) io8-i 14). He also enumerated the Mosses collected by 

 Eobert Brown (Campst.) in Greenland in Trans. Bot. Soc. Edinb. ix. 452. 

 He monographed the Comhretaceae and Mxjrtaccae from the Flora of Tropical 

 Africa^ ii. 413-439 (1871), and also two or three of the orders for the Flora 

 of British India, i. 607-668 (1875). He compiled a MS. index to Jaeger's 

 Adumhratio, which is now in the Botanic Garden Library. His flowering 

 plants, chiefly from Durham and Skye, are also in the Oxford Hei-- 

 barium, but his knowledge of the British plants was not very thorough, 

 and he gradually lost his interest in the subject. Our Oxford climate 

 never seemed to suit him, and he took advantage of the opportunity 

 which was offered him of becoming Director of the Botanical Depart- 

 ment, Ootacamund, where he formed a considerable herbarium, and 

 interested himself in establishing a system by which quinine could 

 be sold at a veiy cheap rate in the villages. He was about to visit 

 England when he was seized with hepatic disease, from which he 

 died at Madras, on Feb. 14, 1896. In 187 1 he recorded in the Journal 

 of Botany, p. 16, the occurrence of Potamogeton (compressum) zosterifoUus 

 in the Thames, near Oxford. This is probably the P. compressum found 

 near Caversham by Milne and Gordon, and noticed by them in the 

 pages of Indigenous Botany. 



Mr. W. Thiselton Dyee, the present Director of Kew Gardens, Dyer, 

 graduated from Christ Church, Oxford. When in residence at Oxford Thiselto-F. 

 he paid some attention to the local flora, as may be seen fi'om the
