When the two plants are in fruit and the capsules quite ripe, the 

 following differences may be noted : — - 



nutans. 



Carpoplwre 3-3^ mm. long. 



Capsule (including carpophore) 

 12-14 mm. long, extreme width 

 5-6 mm. ; diameter of retlexed 

 capsule-teeth 4-5 mm. 



mpe seeds greyish-black, circa 

 1 mm. long by f mm. broad, 

 covered with reticulations and 



tubercles. 



dub la. 



Carpophore circa 4 mm. long. * 

 Capsule (including carpophore) 

 16-18 mm. long, extreme width 

 7^-8^ mm. ; diameter of re- 

 flexed capsule-teeth 5-6 mm. 

 Ripe seeds ash^^-grey, circa 1:^ 

 mm. long by circa 1 ram. broad, 

 covered with reticulations and 



with minute acutely -pointed with minute bluntly-pointed 



tubercles. 



Summing up the various points it may be seen that duhia differs 

 from nutans, 1, by its narrower, more acute, less hairy leaves which 

 are of a brighter green ; 2, by its petals, with a decidedly yellowish 

 tint ; 3, by the narrow and more cylindrical calyx (unlike that figured 

 in Eng. Bot. t. 465) with longer and more acuminate cal5^x-teeth ; 

 4, the capsule and seeds are larger, the latter paler in colour and with 

 blunt tubercles. 



S. infracta W. & K., mentioned b}' Brebisson as a variety of 

 /S'. nutans (Fl. Norm. ed. 5, 60, 1879), may perhaps be discovered 

 in these islands. Griirke (PI. Europ. ii. fasc. 2, 316, 1899) gives its 

 distribution at follows : — Suec. Fenn. Gall. Germ. Helv. Bohem. 

 Morav. Hung. Transsilv. Ross. — Canar. It is evidently much more 

 glabrous than " diihia,'" and M. Corbiere, to whom I sent a Sussex 

 example of the latter, told me that it could not come under the 

 infracta of his Flora (Nouv. Fl. Norm. 91, 1894). 



Two corrections must be made in my former paper : — 1. Dr. Williams 

 tells me that the distribution quoted (op. cit. p. 128) from his account 

 in Journ. Linn. Soc. (Bot.) xxxii. 171, 1896, does not apply to 

 var. duhia, but to the species nutans as a whole ; 2. Later examina- 

 tion of further specimens from Kincardine (St. Cyrus, W. Gardiner, 

 1842 etc.) leads me to believe that they are better left under nutans. 

 Whilst thus losing this county for duhia, we may add S. Hants 

 (v.c. 11), Clement Reid, sp. ! 1911, for this plant, and Dorset 

 (v.c. 9), J. C. Mansel-Pleydell ! 1886, for S. mitans. 



Both nutans and duhia have set a good number of seeds this 

 siunmer and I shall be happy to send botanists interested in these 

 plants some of either or both, so far as the stock permits.
