sulted, as in the case of Plukenet’s plants. The sign ! indicates 
that I have seen an authentic specimen. The references to later 
authors are generally E. Meyer and Choisy, the former of whom 
described Drége’s plants, publishing forty-four new species, of 
which authentic specimens of thirty-three exist ın the Kew Her- 
barium. Choisy twice monographed the order, first, in 1823, in 
the ‘ Mémoires de la Société de Physique et d'Histoire Naturelle 
de Genéve,’ and later, in 1848, in the twelfth volume of De Can- 
dolle’s ‘Prodromus? By “ Choisy” this latter monograph is 
always intended (unless specified to the contrary) as the latest 
revision of the order. Names intended to be kept up (the oldest 
unappropriated name under each genus) are printed in small 
capitals; synonyms, or species mentioned incidentally, in italics. 
The genus Globularia, a separate order in De Candolle’s 
* Prodromus, but much better included in Selagine:, is included 
here for the sake of completeness and because one of the species 
of Linneus, to this day undetermined in books, I have been able 
to identify with G. vulgaris, L., by consulting Plukenet’s type on 
which it was founded. 
To the following gentlemen I offer my best thanks for material 
assistance in various ways, without which it would have been im- 
possible to unravel the intricate synonymy and to present this 
paper in its present form :—to W. Carruthers, F.R.S., of the 
British Museum, for the opportunity of consulting some of the 
types on which the Linnean species were based, as those of 
Plukenet, Linnsus's ‘Hortus Cliffortianus,’ &c.; to Dr. Murie, 
for the opportunity of consulting the herbarium of Linneeus ; 
to Prof. Warming, of Stockholm, for the loan of the Selagineæ 
of the herbarium of Bergius; to Prof. Elias Fries, of Upsala, 
for the loan of the Selagine; of the herbarium of Thunberg, con- 
taining, with one exception, the types of the younger Linnzus 
also (this latter I have found in the Linnsean Herbarium); to 
Prof. Eichler for the loan of the Selagines of the herbarium of 
the Royal Botanie Gardens at Berlin, containing a large number 
of Choisy's types, as it was worked up by him for his last mono- 
graph in De Candolle's * Prodromus ;’ also the types of Link and 
Jarosz ; and, finally, to Sir J. D. Hooker, K.C.S.I., and to Prof. 
Oliver, F.R.S., for their services in obtaining for me the above- 
mentioned herbaria; also to the same gentlemen and to Mr. N. 
E. Brown, for their opinions on a few difficult points in nomen- 
elature.
