340 MR. R. A. ROLFE ON THE SELAGINEJE 
The following brief outline will give some idea of the scope of 
the present paper, with a reference to the latest revision, namely 
that in De Candolle's * Prodromus, vol. xii., to show the altera- 
tions which I propose. 
A. Species described by Linneus prior to Bergius. 
Of the seven species of Globularia, six are unchanged at the 
present time, and the seventh is identical with one of these. Of 
eight species of Selago, four belong to the genus, a fifth is a spe- 
cies of Agathelpis, while three are excluded from the order, viz. a 
Lyperia, a Manulea, and a Stilbe. The two species of Hebenstreitia 
described are both kept up. My only alteration is the redue- 
tion of the four species of Selago to two, the reinstation of the 
second species of Hebenstreita to specific rank, and the determi- 
nation of one species of Globularia. 
B. Species described by Bergius. 
Of five additional species described by Bergius, all belong to the 
Order; one, called Eranthemum, belongs to Agathelpis, one, He- 
benstreitia, to Dischisma; and of the three species of Selago, two 
are correct, the third being a species of Microdon. His three 
Linnæan plants are correctly determined; but one is the afore- 
mentioned species of Stilbe. 
C. Species described by Linneus, after Bergius. 
Of four new species of Selago described by Linneus, one is a 
Stilbe, and three belong to the genus, though one is a plant of 
Bergius under a new name ; aspecies referred to Lippia belongs 
to Microdon; one of Hebenstreitia is correct; and two referred 
to Eranthemum belong to Agathelpis ; but one of them is the plant 
of Bergius under a changed name, which Linnzeus had not seen ; 
and both probably represent the same species. Of the species of 
Bergius enumerated by Linneus, one is wrongly determined in 
the herbarium of the latter, while the true plant, though present, 
is entirely overlooked. 
D. Species described by the younger Linneus. 
A new species referred to Bartsia belongs to this Order, and 
is made up of two species of Lagotis; eleven of Selago represent 
ten species of this genus and one of Microdon; and the two of 
Hebenstreitia represent the same number of Dischisma.
