Czeczott (1960) has reduced the 750 entities to 216. The 
inclusions represent a uniquely restricted sample of the 
original forest, and differ from that presented by either 
a leaf ora fruit and seed flora. Unfortunately, aside from 
amber inclusions, a few ligneous remains are the only 
other indication of the amber forest. Czeczott pointed 
out that an amazing number of cryptogams are preserved. 
Five species of bacteria, a slime mold, 18 types of mush- 
rooms, two lichens, 18 hepatica, 17 mosses and two ferns 
have been described (Caspary and Klebs, 1907; Blunck, 
1929; Magdefrau, 1957). The most common inclusions 
are conifers with 88 species recognized at present. In the 
Pinaceae, there are eight species of Pinus, one of Picea 
and one of Abies. In the Taxodiaceae, there is one spe- 
cies of Glyptostrobus and three of Sequoia. There are 18 
species of five genera recognized in the Cupressaceae 
(three Widdringtonia, four Thuites— including Thyja, 
Thwyopsis and Biota—one Libocedrus, four Chamae- 
cyparis and two Juniperus). Most of the conifers were 
identified on the basis of male fructifications, a few on 
female cone, and some on needle or scale leaves. 
The angiosperms are represented by seven species in 
seven monocotyledonous genera, and 94 species in 57 
dicotyledonous genera (Plate XLII). Forty-seven per- 
cent of the angiosperm inclusions are flower or flower 
parts, and leaves also are relatively prevalent. The most 
abundant angiosperm remains are stellate hairs of oak 
which are almost as common as conifer remains. That 
extensive evidence of pollen has not been recorded seems 
rather surprising, particularly since male inflorescences 
are common. Von Duisberg (1860, 1863) was one of the 
first workers interested in the microflora, although Goep- 
pert had indicated in 1858 that pollen should be found. 
Pollen was not rare in Von Duisberg’s collection, but 
it was difficult to observe in the relatively thick sections
