1895. wild specimens of this hybrid are likely to be very scarce, 
I send some which, grown in light soil, are almost indistinguishable 
from the wild specimens in my possession. — E dward F. Linton. 
Ceratophylhim deinersujii, L. In fruit. Loch Derravaragh, Co. 
Westmeath, 24th July, 1895. — Cinton. I venture to .send a 
couple of sheets of this, as it is rare to find it in fruit, and some 
members may be glad of it. — W. R. Linton. “I should have said 
rudiments of fruit, rather than fruit, and from habit should have 
named this specimen C. submersimi. Unless the fruit is ripe it is 
utterly impossible to name the forms, as the change frpm young to 
ripe fruit is accompanied by corresponding changes in the spines, etc.” 
— Ar. Bennett. 
Iris foetidissima, L. var. citrina, Syme. Swanage, Dorset, 6th 
July, 1895. A well marked and apparently quite stable colour- 
variety, of a particularly clear and pure, though not a deep or 
brilliant shade of yellow. My father, the Rev. Lester Lester, 
knew three stations for it in Burbeck 30 years ago. I searched 
all three carefully this year, but failed to find it. I was fortunate 
enough, however, to discover two isolated plants this summer, 
in widely-distant stations where he had never seen it. One of 
these formed a fine strong clump, and furnished almost all the 
specimens which I send. Is this variety known from any other 
locality except the east end of the Isle of Purbeck ? — L. V. Lester. 
“ Syme (E.B. iii.) mentions it as occurring in the Isle of Wight where, 
according to Townsend’s ‘ Flora of Hampshire,’ it is found in North 
Wight (Dr. Bromfield) and South Wight (Mr. F. Stratton).”—

Simethis bicolor ^ Kunth. Branksome Park, Dorset, 28th June, 
1894 ; 28th May and 19th June, 1895. In this, its one known 
English locality, this plant is probably as abundant as it has ever 
been, though confined to a few square yards in a fir-wood of miles 
extent. — W. Moyle Rogers. 
Juncus . An intermediate between 'J. compressus and J. 
Gerardi. Damp sand on the shore of the Bristol Channel, at Berrow, 
North Somerset, August, 1887. — Jas. W, White. 
J. tenuis, Willd. Between Bridge of Weir and Kilmalcolm, Ren- 
frewshire, on roadside turf. Sept., 1895. — Somerville. 
Potamogeton sparga?iiifolius, Laestad. River Maam, Co. Galway, 
5th July, 1895. — -W. A. Shoolbred. “I doubt much this being the 
true plant of Laestadius, notwithstanding the late Prof. Babington’s 
opinion that it was (cf. ‘Journal of Botany,’ 228, 1872) so. My 
specimens, gathered by Laestadius himself, differ in many points; and 
I think we must, anyhow at present, use Syme’s name — P. Kirkii, 
until a careful study of the plants in situ is made. In his ‘ Loca. 
parallela plant.’ in a note on spargafiii/olius, Laestadius observes.
