ce of the" annular ring". According his examination, exine of Sequoia sem- pervirens, Glyptostrobus pensilis and Taxodium distichum becomes thin in

thickness in the annular ring as in Cryptomeria japonica.

The present specimens are identified withSequoiapollenites gracilis Kru- tzsch from the early and middle Tertiary of middle Europe.

Botancial affinity: Taxodiaceae, Sequoia.

Sequoiapollenites sp. a PI. 56, fig. 2.

Description: Small conifer pollen grain with a short ligula. Outline subcir- cular to oval in lateral view. Exine very thin, finely punctate to weakly granu- late, with secondary folds. The grain possesses no annular ring which is provided with a short ligula (2. 5 /l.m long), which is laevigate and tapers off swiftly.

Measurements: 31 X 26 /l.m in diameter.

Occurrence: Uge Member, south of Kanuka (C 31).

Remarks: A single specimen was found. This grain has no annular ring ar- ound a short ligula.

Botancial affinity: Taxodiaceae, Metasequioa.

Sequoiapollenites sp. b PI. 56, fig. 5.

Description: Small conifer pollen grain with a long ligula. Outline somewhat oval in lateral view. Exine very thin, chagrenate, with secondary folds. The grain has a clear annular ring which is smooth in exine and the long ligula8

p,m long and4 p,m wide at base, somewhat punctate near base.

Measurements: 25 X 14p,m in diameter.

Occurrence: Uge Member, south of Kanuka (C 31).

Remarks: Only one specimen was observed. This is similar toSequoiapolle- nites megaligulus Krutzsch (1971, p. 222, pI. 73, figs. 25-35)from the Oligo- Miocene of Germany, but differs by its form of the ligula and structure of the exme.

Botancial affinity: Taxodiaceae, Sequoia.

Description: SEM photomicrograph. The grain is splitting. Exine finely uneven. A small ligula is situated on the middle of grain probably with an annular ring in polar view.

Measurements: 17.6 J.lm in diameter.

Occurrence: Uge Member, south of Kanuka (C31).

Remarks: Only one specimen was observed. This is a small form with a lig-' ula.

Botancial affinity: Taxodiaceae.
