not already on record. The Hop (fruiting - ) and the CEnanthe 

 fistulosa, Conium, Rosa spinosissima, Reseda luted, Asperula 

 cy?ia?ichica , and Carex acuta were noted, all in their Flora 

 stations, still undiminished though not increased. The Scirpus 

 acic atari's of the Ing\s brook appeared to have vanished ; Salvia 

 verbenaca seemed nearly 'done for' by the field wall near the 

 Union-house, although not so its close neighbour Verbena y for it 

 can bear trampling upon by many feet. The curious form of 

 the Perfoliate Pondweed (Potamogeiou perfoliatus var. Jacksoni) 

 (1596 x c. Lond. Cat. Edn. 9th) discovered in a' pool at Linton 

 by Mr. John Jackson in 1881, would seem to have disappeared, 

 too, owing to alterations ; but as it has one other locality in the 

 fens, and has been determined by Mr. A. Fryer to be a hybrid, 

 pollinated by the crimped-leaf Pondweed (P. crispus) with which 

 it so often grows, it is almost sure to reward special search 

 for it under Linton Bridg'e. Many of these things are not really 

 rare — one has only to ' go ' for them with serious alertitude ; 

 and lo ! after the initial maze of tangle has been secerned and 

 sorted — three or four 'species' at one haul — there it is, the 

 nameable, differentiated article — and the collector is satisfied 

 and happy ! This is a parable. 



Near the head of the alluvial Ings level, the North African 

 Lyciuni barbarian, 'False Tea-tree,' a good 'quickset' for 

 hedges, introduced because it will bear maltreatment and form 

 a good fence, has established itself, probably bird-sown, and 

 acquired the rights of a wilding; whilst a much older 'simple,' 

 or potherb, in use by the Norman — the Sand Leek {Allium 

 arenarium or Scorodaprasum) has very greatly increased during 

 the last twenty years by the banks of Wharfe on the west or 

 northern side. Very handsome its rose umbels and capitula of 

 purple bulbils, topping its broad leaves, showed ; in clumps 

 about winter-flood mark, where year after year, in this creek or 

 by that backwash bank they had been Nature planted ! It is 

 one of the plants that, like the other Alliums, Schcenoprasum 

 and Babi?igtonii, may be either indigenous, or a very, very old 

 introduction. About Abbeys, Norman earthworks, like Rouge- 

 mont near Weeton, eight miles higher up the Wharfe, on its 

 north bank, too, and the site of Harewood's first castle, such 

 plants as this Garleek, Goutweed, etc., are commonly found to 

 persist and, more than that - the significant factor- to increase 

 in frequency and quantity lower down the nearest waterway. 



'With this exception, a river-borne influx, there might never 

 be any natural change in the character of the flora to keep in
