elegantissima affinis S. acauli, L., et S. ewscape, All, et quasi inter-

wonder) guamvis certissime characteribus bonis et constantibus distincte 
Sint." . . . “Jam vero queritur, num S. dryoidea propria sit species 
an non. A Silene enim acauli non differt nisi calyce non umbilicato 
(limbo petalorum integro, capsula latiore et breviore omnibusque par- 
tibus, exceptis foliis, majoribus"—almost imperceptible distinctions) ; 
* Silene autem exscapa non nisi floribus subsessilibus duplo minoribus 
et capsula ovali calyce subinclusa ab ea distincta est. Jam quum S. 
éryoidea in consortio Silenes acaulis et exscapse crescat, hanc stirpem 
nil nisi formam inter illas duas species hybridam esse, valde probabile 
mihi videtur."—Surely a subject hardly meriting an imperial-quarto 
plate and a page and a half of descriptive matter ! 
The Alsinee follow in the work next after Silenee. Malachium ca- 
lycinum, Wilk., very nearly approaches M. (Stellaria) aguaticum, Fr. 
Five species of Cerastium are figured, and a Conspectus of species is 
given, twenty in number. Tab. 60 B. represents a new Menchia, M. 
octandra (Malachium octandrum, Gren., Cerastium cceruleum, Boiss.). 
Two species of Mehringia are figured, and six recorded. The Stellarie 
of Austro-occidental Europe are, all of them, British. The ninth fas- 
ciculus closes with the tenth species of the genus Arenaria, viz. "A. ser- 
pyllifolia, L. All are well executed plates, with ample diagnoses. 
FLonA Unrversatis in colorirten Abbildungen. Ein Kupferwerk zu den 
Schriften Linné’s, Willdenow's, De Candolle's, Sprengel's, Rómer's, - 
Schultes’s u. A. Herausgegeben von Dr. Davip Dietricn. Small 
folio. Jena. Fasc. 8. Ten Plates. 
Of this new work, now in the course of publication, as it would 
appear, at Jena, we have seen only one fasciculus (the eighth, issued in- 
August, 1855), which has been addressed to us by Dr. Sonder. It is 
unfortunately unaccompanied by any notice or prospectus, beyond what — 
is learned from the title. Judging by that and the contents of the _ 
present number, the object of the work is to give coloured representa- _ 
tions of new plants, or of such as have not been figured previously, 
with dissections. This fasciculus is accompanied by a page of letter- 
press, confined to the name of each, a reference to the author who has 
described it, and an explanation of the dissections of the flowers, etc.
