Di PLOSANTHER^ j this Clafs comprehends all thofe Plants vvhofe 
Chives exceed, as far as a double proportion, their Petals ; and 
takes in moft of LinnjT:us’s odl. dec. and dodecandrias. The 
hrH; order has the Arbutus, and its aflbciates j the fecond and third, 
the Lychnis’s, Alfines, and fome few of the Multifiliqua,' j all very 
tolerably. The laft order is compofed chiefly of Trees. The Poly- 
anthera: is the fame with Linn^^us’s Polyandria ; and, like that, 
has a great mixture of Plants, though the Multiflliquoe ftand well 
together. 
Cryptanther^ take in a few of the Filices, Mufci, Algae, and 
Fungi. 
Lastly, the Lithophyta the flony Plants. 
This is the difpofition of Royen. Let us fum up in a few words 
our opinion of it. He has got together many natural Clafles, and in 
his mixed ones are leveral good orders j but in doing this, he has not 
fo much followed Nature as other men’s obfervations j from hence 
proceed his faults. He has little ftudied to conned! one Clafs with 
another : his orders, and his Genus’s are too often liable to the fame 
defedl. The numerous exceptions to his general charadters have been 
mentioned before. 
Haller writ about the fame time, though his Vv’ork did not appear 
till a year after. Many of his Clafles are the fame with Ray's but 
flniflied in a very different manner, with great knowledge and a vafl; 
llorc of natural obfervations. His method is not general, anv more 
than Royen’s, but confined to the Plants of Sw i tzerl and. I can- 
not approve of the length of fome of his Clafles ; for there are two, 
the Apetala: and Ilbflemones, that include almofl half his Genera ; 
and we fhall multiply his Clafles too much, by giving that name 
to his orders, Befides, they often contain but one or two Plants. 
All this will better appear on examining his Syftem.
