212 BERRY— LOWER EOCENE FLORA OF [April 25, 



European, with a single species on the east coast of Asia (Sachalin) 

 and two species in Colorado, one of them especially well marked. 

 There are several Pliocene species in southern Europe. 



Two somewhat different species of sterculiaceous capsular fruits 

 from the Wilcox are referred to a new genus, Sterculiocarpus. The 

 larger of these, S. eocenicus, seems referable to the subfamily Buett- 

 nerie?e, while the smaller, S. sezannelloides, is referable to the Lasio- 

 petaleae or Helictere?e. Both are very similar to the fruits from the 

 I'aleocene of Sezanne referred to the genus Sczannclla. The latter 

 genus with two species was described by Yiguier from casts of 

 wonderfully preserved flowers as well as fruits from the celebrated 

 Travertins of Sezanne and referred with great certainty to the 

 Lasiopetaleae. 



The tribe Dombeyea? with seven genera and about 75 existing 

 species is almost entirely confined to Africa and the adjoining 

 islands, five or six species of the genus Melhania Forsk, only, rang- 

 ing from Arabia to farther India. This tribe is represented in fossil 

 floras by the genus Dombcyopsis Unger named from its supposed 

 affinity with the modern genus Dombcya Cav. which has 40 African, 

 mostly Madagascar, species. About 30 species have been referred to 

 Dombcyopsis. They are liable to be confused with Luhca, Grewia 

 and other forms of the allied family Tiliacea?. There are three 

 species in the Laramie Cretaceous, two in the Denver formation, 

 twelve (according to Massalongo) in the Upper Eocene of Monte 

 Bolca in Italy, five in the European Oligocene and six in the Miocene 

 of Iceland, France, Switzerland, Prussia, Silesia and Styria. A 

 Pliocene species is recorded from central France. Fossil wood 

 described as Dombeyoxylon is recorded by Schenk from the late 

 Tertiary near Cairo, Egypt. 



The Buettnerieae are represented by a doubtful species described 

 from the Miocene of Colorado, and probably by some of the fossil 

 forms referred to other genera, e. ,'/.. some of the palmately veined 

 Ficus-like forms such as Ficus occidentalis and Ficus Schimperi both 

 of which are present in the Wilcox flora. Flowers of Buettneria 

 were reported from Sezanne by Solms-Laubach but this probably 

 refers to the subsequently described genus Sesannella, mentioned in 

 a preceding paragraph.
