Within these few years several very able botanists have undertaken a new arrangement of the plants belonging
to the natural order Umbelliferee, the difficulties attending the study of which are known to every one who is in the
slightest degree conversant with Botany. Hoffmann and Sprengel have both introduced many and very important
improvements: but Smith, in the second volume of his inestimable English Flora, has, we think, with more success
than any other, arranged and characterized the umbelliferous plants; that is, those which are natives of the British
islands. His character we have adopted, therefore, for our Tordylium, and we shall continue to follow those of the
same learned author for the different individuals of the family that we may figure in this work.
We have just received another most elaborate arrangement of the umbelliferous plants, published, as a memoir,
in the 12th volume of the Acta Acad. C. L . C. Natures Curiosorum, p. 56, by Dr. W. D. J . Koch. The great
importance of the fruit is here, as by preceding writers, strongly dwelt upon, and the characters are principally
taken from it. The memoir is illustrated by many well executed lithographic plates, by which the various terms
employed are rendered perfectly intelligible. From what we have as yet seen of this memoir, the species appear
to be grouped with great attention to their natural affinities.
Of the genus Tordylium there are but two species mentioned as native of Britain, and those are of considerable
rarity. The T. officinale, indeed, Sir J . E. Smith suspects has never been seen at all in England, the present species
having been mistaken for it, which latter has only been found about London (Morison); under the hedge on
the north side of the parks, Oxford (Dr. Sibthorpe and Mr.Woodward); and in a hedge about half a mile from
Eton (Mr. R. Gotobed). From the Oxfordshire habitat our specimen was kindly communicated by our valued
friend J. E. Bicheno, Esq. with the remark that it is “ perhaps not an indigenous station.”
Tordylium officinale differs from T. maximum in its shorter ovate leaflets and its white conspicuously radiant
flowers. The genus is remarkable for its depressed and margined seed-vessels.
