it does the range from Devon and Cornwall so much eastwards. 
This unexpected occurrence of such a very local western species 
led one to think it must have been introduced in recent times. 
I made a careful examination of the natural strip of wood 
in which it grows but found no other suspicious plant, and the 
wood itself was formerly united to other woods in the vicinity. 
The Physospermum grew in great quantities over a somewhat 
limited area. During the years I worked that neighbourhood it 
was extremely dense brushwood, into which I did not penetrate, 
and was closely preserved. About three years ago the undergrowth 
was cleared, and that the Physospermum has not been introduced 
since is proved by some plants appearing through the bundles of 
faggots which were then cut. Although on dry flinty soil (the 
Upper River gravels) Rhamnus Frangula grew in it with Euonymiis. 
In many ways the place reminded me of the wood at Bodmin 
where it grows. At present I am inclined to think the plant is 
indigenous there. — G. Claridge Druce. 
Apium 7 iodiflorum, Reichb. f., form or var. In moist, peaty soil, 
near Chalvey, Bucks, August 1904. This plant, although very dif- 
ferent in appearance from the coarse plant of our midland streams, 
yet cannot, I think, be referred to the var. ocreatiwi, Bab., and cer- 
tainly not to A. repens or its variety (as I place it) tongipedunculatum. 
It grew in moist, peaty soil. Our British forms of Apium would 
bear further investigation. — G. Claridge Druce. “ I have re- 
ceived, thanks to Mons. Casimir De Candolle, a photograph of the 
type of Helosciadium nodiflorum B ochreatum DC., Prod. IV. 104. 
Mr. Druce’s plant from Bucks resembles this in almost every leading 
characteristic with one exception, that is, that the umbels in the type 
of ochreatum^ DC., tend to be slightly more longly peduncled. This 
variety must not be confused with var. ocreatum, Bab.” — E. G. 
Baker. “ This goes some way towards var. ochreatum of DC. The 
outline and number of leaflets and length of peduncles fairly well 
suit DC.’s variety, in which leaflets are as in type Jiodiflorum, But 
the Chalvey plant {quoad my specimen) shows no signs of rooting in 
the upper half of the stem, whereas DC.’s type specimen (for sight 
of photograph of this I am indebted to Mr. E. G. Baker) roots at 
the nodes almost to the end : and the serration of the leaflet is 
deeper and coarser than in DC.’s plant.” — H. J. Riddelsdell. 
'rhe Rev. E. F. Linton remarks of this and the following : “ Both 
A. nodiflorum R. fil. I do not see the supposed variation from type.” 
A nodiflorwji, Reichb. var. ocreatum, Bab. Cropstone Brook, 
Leicestersh., 8th Aug. 1904. “This agrees with a specimen I have 
under the above name. The umbels are nearly or quite sessile — 
a character emphasized by Babington.”— W. Bell. “ Babington de- 
scribes the leaves of his var. ocreatiun as ‘ roundish, ovate, small, 
and bluntly toothed,’ and he quotes E. B. tab. 1431. The plant
