less or more normal mode of sexual reproduction as illustrated by partheno- 
genesis and that kind of dimorphism in whic i nd clo 
flowers are self-fertile, as in Leersia, Eranthemwm, ete. Giving due weight 
to these several relations, it is evident that the argument founded by. 
I. von Mohl and others on the occurrence of minute, closed, and per- 
fectly self-fertile flowers, in no way weakens Mr. Darwin’s doctrine that 
no species is self-fertilized. 
NOTES ON BRITISH GENTIANACEZ.

and authentic specimens has enabled me to clear up, in my own mind at 
least, many of the difficulties which I had previously experienced, to correct 
several published errors of name, and to add some further facts with re- 
ference to the distribution of the plants, which may be of use to students 
of our native species. : 
Erythrea littoralis, Fr. Mr. Watson (Comp. Cyb. Brit. 248) queer 
Moray for this species, and Dr. Boswell Syme states that he has “not 
seen specimens” (Eng. Bot. ed. 3, vi. 66). I have examined specimens 
from the following localities on the shores of the Moray Firth :—“ Seaside 
near Brodie House,” Elgin, distributed by G. Don in his Herb. Brit. 
Fasc. i., under the name of Chironia pulchella [see Hook. Fl. Scot., p 
322], and salt-marsh, near Campbellton, Inverness" (Gardiner), which 
Kew., others from the ‘ South shore of the Moray Firth, between Burg- 
head and Findhorn (Rev. G. Gordon)", and from the ‘Solway coast. . 
The two forms figured. in Eng. Bot. ed. 3, are well represented in lies 
Mus. Brit., where there isa remarkably fine set of the British species 0 
the genus. In the useful but unfortunately incomplete ‘ Flora of Liver 
pool District,’ issued in 1866-68 with the ‘Liverpool Naturalists’ Journa 
is the following note upon th varying habit of this species

E. latifolia, Sm. The “ Erythrea latifolia, L.," of Mr. Hemsley * 
Sussex list (Journ, Bot. vi. 264), given on the authority of specimens in 
Herb. Borrer, is that form of E. Centaurium which is frequently misca d 
latifolia, as in Mr. Keys’ ‘Devon and Cornwall Flora," and which was figure 
as such in E. B.S. t.2719. The true Æ. latifolia is not represented ys
