Yes. But I doubt it coming true from seed ; I have seen it in 
various stations, always in poor and exposed soils. — E. S. M. 
Chenopodium polyspermum, L., var. cymosum, Moq. Linden 
Drive, Evington, Leicester, Sept. 1908. — W. Bell. Very good 
cymosum. — E. S. M. Yes: good and typical, and well prepared. — 
H. J. R. 
Chenopodium opulifolium, Schrad. Orig. Aberdare, Cult. 
Llandaff, 1 908. Is this right ? I could not tell when I first 
gathered it, and so grew it from seed. — H. J. Riddelsdell. Yes : 
agrees with specimens I hold so named, except tliat the foliage 
of Mr. Riddelsdell’s plants is rather smaller. — \V. B. Yes. —

Atriplex spongiosa, F. von Mueller. This is a “ wool intro- 
duction ” found by me growing on alluvial soil at the junction of the 
Gala and the Tweed. A native of South Australia; and the first 
record for Great Britain. This is a much branched herb or under- 
shrub, with numerous ascending or erect stems, not above 9 inches 
high, more or less mealy-white, becoming glabrous when old. The 
berry-like spongy fruit of the plants found at Galafoot turned from 
pale green colour to dull red. The testa came off leaving the inner 
membrane with ripe seeds. It may be at this stage the seeds adhere 
to the wool. I am sorry not to have more specimens ; but hope 
next year to have better and more to send. — I. M. Hayward. 
Polygonum aviculare^ L.,var. microsper mum []ord.). Abundant 
at Trent Station, Derbyshire, v.-c. 57, August, 1908. — F. I.. Foord- 
Kelcey. Certainly small-seeded ; but the whole plant is evidently 
starved. Not F. ?nicrosperfnujn, Jord., I should say. — E. S. M. 
[This remark applies to the next plant, though less decidedly. — 
E. S. M.] The late Rev. W. R. Linton informed me some time ago 
that microspermum has small “included” fruit. This description 
will not suit the Trent Station plant, which comes best, I think, 
under var. arenasirum (Bor.). Corbiere makes this a form of var. 
humifusufii (Jord., Bor.), differing from it by its small oval-oblong 
leaves, which in humifusum are oblong-lanceolate. — C. E. S. 
P. microspermum, Jord. Malpas Station, Cheshire, 5th Aug. 
1908. Growing on a cinder platform, mixed with a small quantitv 
of P. agrestinum, but keeping quite distinct from it. Absolutely 
prostrate. — A. H. Wolley-Dod. 
Rumex crispus, L., var. triangulatus, Syme. Sea cliffs, near the 
Lighthouse, Langness, Isle of Man, Sept. 1908. New to the Manx 
Flora. — J. A. VVheldon. Yes; but not very strongly marked. 
The var. is not quoted in ‘ Lond. Cat.,’ Ed. X. ; it is difficult to see 
why it is omitted. — H. J. R.
