LINNEAN CLASSES. 37 
anna II, Dianpria (dv, twice), with two stamens to each

IIT, Trianprta (tes, thrice), with three stamens. 
IV, Terranpria (tetge, four times), with four stamens. 
V, Pentanparia (7772, five), with five stamens. 
VI, Hexanpria (é6, six), with six stamens. 
VII, HepranpRia (é2te, seven), with seven stamens. 
VITI, Octranpria (oxtw, eight), with eight stamens.

2d. Position. The next two classes depend upon the posi-

XII, Icosanpria (éz00v; twenty), cludes those genera 
of plants which have twenty or more stamens to 
the flower, seated on the calyx (perigynous). 
XIII, Potyanpria (zo4vc, many), twenty or more stamens, 
seated on the receptacle (hypogynous). 
3d. Relative length. 'The two following classes are founded 
upon the relative length of the stamens, together with their 
number. : 
XIV, Dipynamia (01s, twice, duw, two, vyue, a filament), 
meludes plants with four stamens, of which two 
are long, and two are short. 
XV, TeTrrapyNnamia (tét9e, four times, duw, vyue), with six 
stamens, of which four are long, and two are short. 
4th: Connection. 'The five succeeding classes depend upon 
the connection of the stamens, in various ways. | 
XVI, MonavEtpuHia (wovos, adelgos, a brother), includes 
plants with the filaments united into one set or 
fraternity. 
XVII, DiapEtputa (dum, adelgos), into two sets or fraternities. 
XVIII, Poryapetputa (zolvs, adedgoc), into many sets or fra- 
ternities. 
XIX, Syneenesia, (ovr, together, yeveors, origin), stamens 
united by their anthers, into a tube.
