Abstract:

The names of thirty-nine species of fossil spores and pollen recognized by various palynologists, but not validly published, are validated by providing information on repository of their holotypes. Of these, 10 species are of pteridophytic spores, 2 species of gymnospermous pollen and 27 species of angiospermous pollen. The new species names are: Acanthotricolpites brevicolpus R.K. Kar, Acanthotriletes triangulatus A. Kumar & K. Takah., Assamialetes minutus A. Kumar & K. Takah., Biretisporites minimus A. Kumar, Conitricolporites triangulus R.K. Kar, Corrusporis indicus A. Kumar & K. Takah., Cycadaceaelagenella minor A. Kumar & K. Takah., Cycadaceaelagenella psilata A. Kumar & K. Takah.,Dicolpopollis psilatus A. Kumar & K. Takah., Hibisceaepollenites robustispinosus R.K. Kar, Incrotonipollis mannargudensis M. Acharya (based on “Crotonipollis mannargudensis M. Acharya”), Intertriletes reticulatus A. Kumar & K. Takah., Intrapunctosporis cacharensis A. Kumar & K. Takah., Laevigatosporites robustus A. Kumar & K. Takah., Lanagiopollis reitsmae Phadtare & B. Thakur, Lanagiopollis rugulatus Phadtare & B. Thakur, Lanagiopollis ruguloreticulatus Phadtare & B. Thakur, Meyeripollis triradiatus A. Kumar & K. Takah., Palmidites minor A. Kumar, Palmidites psilatus A. Kumar, Polyvestibulopollenites assamicus A. Kumar & K. Takah., Psilastephanocolpites elongatus A. Kumar & K. Takah., Psilastephanocolpites kumarii R.K. Saxena (“Psilastephanocolpites minutus A. Kumar & K. Takah.”), Psiloschizosporis scabratus R.K. Kar, Pteridacidites minor A. Kumar, Pteridacidites tripuraensis R.K. Kar, Racemonocolpites thanjinathensis J. Mandal, Racemonocolpites trichotomosulcatus J. Mandal, Retibrevitricolpites macroreticulatus A. Kumar & K. Takah., Retipilonapites barakensis A. Kumar & K. Takah., Retistephanocolpites assamicus A. Kumar, Scabrastephanocolpites ovatus A. Kumar & K. Takah.,Striatocolporites takahashii R.K. Saxena (“Striatocolporites minor A. Kumar & K. Takah.”), Tamilnaduapollis reticulatus M. Acharya, Tricolporopilites magnus M. Acharya, Verrualetes baculatus A. Kumar, Verrualetes excellensus M. Acharya, Verrucosisporites miocenicus A. Kumar & K. Takah., and Verrutriporites sparsiverrucatus A. Kumar & K. Takah. The genera Conitricolporites R.K. Kar (Type: C. triangulus R.K. Kar) and Tamilnaduapollis M. Acharya (Type: T. reticulatus M. Acharya) are also here validated with the validation of their respective types.
