female flowers distinct and without any pistillu n ; and the seeds, 
consisting only of a naked corculum, without cotyledon or tunic. 
The genera of this order have been distinguished by Linnaeus, 
according to the following circumstance, viz. the antherse, with or 
without a calyptra,* placed on the same plant as the female floret, 
or on a distinct one ; and the female aggregate, or, single. The 
order contains eleven genera, viz. Lycopodium, Wolf’s Claw Moss, 
Perolla, Sphagnum, Bog Moss, Phascum, Splachnum, Polytnchum, 
Golden Maiden Hair, Muium, Bryum, Hypnum, Fontinalis, Water 
Moss, and Bushaumia. , , , , 
Oiidek III. ALGyE, Flags. The plants comprehended under 
this order have their root, stem, and leaf all in one. The charac- 
ters of the fructification of this order are not yet know, excepting 
the few descriptions given by Michelius. The genera are twelve, 
viz. Jungermania, Targionia, Marchantia, Blasia, Iviccia, March 
Liverwort, Anthoeeros, Lichen, Liverwort, Tremella, Fucus Wrack, 
or Sea Weed, Ulva, Laver, Conferva, and Byssus. 
Okdeu IV. FUNGI, Mushrooms. The genera of this order are 
given bv Limueus after the method of Dillenius. r Ihe fructification 
being imperfectly known, no character can he assigned tor tins 
order, farther than the title, which is familiar to every one. Ihe 
genera are ten, viz. Agaricus, Agaric, Boletus, Hydnum, Phallus, 
Stink-horns, Clatlirus, Helvetia, Peziza, Cup Mushroom, Clavana, 
Lycoperdon, and Mucor. 
Of the twenty-fifth Class. Palmas. 
Comprehending such plants as have a spadax and spatha This 
order contains nine genera, viz. Chamaerops, Dwarf Palm, or 
Palmetto, Borassus, Coryplia, Cocos, Cocoa Nut, Phoenix, Common 
Palm, or Date Palm Tree, Elais, Areca, Arica Nut, Elate, and 
Caryota. 
From this short sketch of the science of botany , it will be easily 
seen in what manner it is applied, in order to discover the genus 
aud species of any unknown plant. When, a plant is gathered m 
flower, the number of the stamina will refer to the class, and the 
pistils to the order, except in the twelve last, classes, which are 
distinguished bv other marks. When the order is found, the genus 
is next; to be discovered, which is done by observing the calyx, the 
corolla the pericarpium, and the seeds, as well as the form and 
situation of the stamina and pistils. The species are distinguished 
bv «ome specific difference of the root, the trunk, the branches, or 
the leaves, and they are called by some trivial name, expressive of 
the specific difference, or some other circumstance ; thus we find 
the vellow gentian, the lesser centuary, the rough-leaved, and the 
smooth-leaved witch elms, &c. It is evident, that in such a work
