'''Brief summary'''
 
*Large robust rings that become amoeboid during later development
*Red cells become increasingly enlarged and distorted
*Schüffner's dots present in appropriately stained samples
*All forms tend to circulate with large schizont and gametocyte forms

'''Brief summary'''
 
*Large robust rings often retained in late trophozoite stage
*Red cells enlarged with oval shape and characteristic fimbriation
*Schüffner's dots seen in well stained samples
*All forms tend to circulate, parasites large but smaller than for ''P.vivax''

[[File:PMcombi.jpg|right|400px|link=PLASMODIUM MALARIAE]]
 
 
'''Brief summary'''
 
*Small rings (less delicate than ''P.falciparum''); becoming elongated or solid
*Red cells often small remaining round with no added dots
*All forms tend to circulate, characteristic "daisy" schizonts and small round gametocytes''
*Parasite number is often low

'''''Plasmodium knowlesi'''''
[[File:PKcombi.jpg|right|400px|link=]]
 
 
'''Brief Summary'''
 
*Very limited geographical distribution
*Small fine ring forms resemble ''P.falciparum''
*Later rings are more solid or elongated similar to ''P.malariae''
*Faint dots (Sinton or Mulligan's stippling) appear at later stages
*Schizonts & gametocytes resemble ''P.malariae'' but are less "neat"
*Characteristically red cell size is unaffected, although distortion may be seen
