Rosa tomentosa, Sm., var. b. suhglohosa. " I know of two localities 

 for this, one by roadside near Woolmer Green, on gravel, and another 

 on chalk dug out of the tunnels near Welwyn, Herts." — T. B. Blow. 

 "St. Stephens, E, Cornwall, July and September, 1875." Remarkable 

 for the soft texture of its densely hairy leaflets, which have few or no 

 glands on either surface. The Cornish plant has shorter peduncles 

 than the Welwyn one, in this respect answering the better to Smith's 

 description in his " English Flora." — T. R. A. B. 



Rosa micrantha, ^m.., var. pedimculo nudo. "Hedge between 

 Efford and Egg Buckland village, S. Devon, 1875." This naked- 

 peduncled variety of micrantha is put with R. tomentella, Leman, by 

 M. Desegiise, an arrangement which I cannot adopt. It differs from 

 the type only in having naked peduncles and sepals with few or no 

 glands on the back. The var. Briggsii, Baker, is simply a luxuriant 

 form of this. The naked-peduncled plant has been recently recorded 

 by Dr. Christ from " Vallee de Cianzo," near Santa Anna, on the 

 Maritime Alps.— T. R. A. B. 



Rosa stylosa, Desv., var. a. systyla. East. "Hedge near Adisham, 

 Kent, September, 1875." — T. B. Blow. "Near Saltram, S. Devon ; 

 Hay Lane, between Torpoint and Antony, &c., E. Cornwall." This is 

 undoubtedly the systyla of the Continental botanists, as received from 

 M. Desegiise ; and specimens from the neighbourhood of Plymouth 

 have been so named by him. Here it is quite a common Rose and 

 widely distributed.— T. R. A. B. 



? var. leucochroa^ Desv. " Hedge, Cutmere, St. Germans, E. Corn- 

 wall, July, 1875. Between St. Johns and Whitsand Bay, E. 

 Cornwall, September, 1875." This has a much stiffer habit than true 

 systyla, shorter peduncles, a less prominent disc when in fruit, and 

 styles commonly not so much agglutinated, or quite free. The petals 

 are white, though of a creamy tint when expanding. M. De'seglise 

 has had specimens from several places in Devon and Cornwall, and 

 has pronounced them to be leucochroa. I used to regard this Rose as 

 the collina of Jacquin, but am now satisfied that it is not that. It 

 seems to be nearer to systyla, Bastard, than to any other of our Roses. 

 It is abundant about Plymouth. — T. R. A. B. 



Rosa arvensis, Huds., h. bihracteata. "Hedge between Latch- 

 brook and Notter ; " also " Sheviocke, E. Cornwall, 1875." This luxu- 

 riant variety of arvensis proves to be widely distributed about 

 Plymouth, occurring both in Devon and Cornwall. Mr. Bagnall has 

 sent a number of specimens from " Butler's Hill, near Tardebig, 

 Warwickshire." The calyx-tube of this last is broader when in fruit 

 than in the Plymouth examples, but the long-pointed and very 

 sharply-cut leaves, together with the luxuriant habit of the plant, are 

 quite characteristic of bihracteata. — T. R. A. B. 



Callitriche Lachii, Warren MS. " Tabley Moat, Cheshire, 

 September, 1868. It seems possible that this may prove an un- 

 described Callitriche. I regard it as intermediate between hamulata 

 and obtusangula. It has nearly the fruit of the latter, with remarkably 

 long persistent styles. But its upper leaves are nearly linear, and the 

 general habit of the plant, except the topmoi^jt rosette, is nearer coarse 

 hamulata. Dr. Boswell will remember I sifnt him portions of this 

 specimen last year. This year in July (in company with Mr. Webb)
