FOSSIL FAUNA AND FLORA OF THE FLORISSANT SHALES 169 



SPERMATOPHYTA 



DicoTYLEDONES (about 1 25 specics) 



Compositor ( I species) 

 A thistle, Carduus florissantensis Ckll., has been described from a specimen 

 collected by Judge Henderson and Dr. Ramaley. 



CoHvolvulacccB (2 species?) 



Two "scariose calyxes" are described by Lesquereux as belonging to the genus 

 Parana, which has several species in the European Miocene, and one in the John 

 Day Miocene of Oregon. 



Apocynacece (i species?) 



Apocynophyllum scudderi Lx., was described from the Green River beds of 

 Wyoming; but Kirchner lists it from Florissant, on the strength of a specimen in 

 the collection of Dr. Hambach. No particulars are given, and I think the occur- 

 rence of the species at Florissant needs confirmation. 



OleacecB (8 species) 



No less than seven species of Fraxinus are described by Lesquereux; but of 

 one it is said that it may be a Myrica. Two are uniigured. The leaves described 

 as Fraxinus libbeyi are curiously similar to those of Ulnius braunii. In addition 

 to the new species, F. prddida Heer is reported, but on the basis of a very unsatis- 

 factory fragment. This species is also said to occur in the Denver beds at Golden. 

 Osmanthiis prcsniissa {Oka prcBmissa Lx.) is represented by a beautiful specimen, 

 showing leaves and flowers. 



Ebenacece (2 or more species?) 



Two species represented by leaves, and referred to Diosypros brachysepala 

 Al. Br. (originally described from Europe) and D. copeana Lx. The first of these 

 appears to be more especially a Laramie species, while the second originally came 

 from the Green River beds in Nevada, and is not cited by Knowlton from any 

 other place. The recognition of these species in the Florissant flora must doubtless 

 be considered wholly provisional. Two other species, Diospyros cuspidata Kirch- 

 ner, and Macreighiia crassa Lx., are based on calyces. Their value as evidence is 

 clearly very slight, and they possibly represent different interpretations of the same 

 thing. 



SapotacecB (i species) 



Bumelia florissanti Lx., is described. 



MyrsinacccB (i species) 

 Myrsine latijolia Lx., is based on a fragmentary leaf. 



EricacecB (r or 2 species) 

 Andromeda rhomboidalis Lx. is described but not figured. Another leaf is 

 referred, quite hypothetically, to Vaccinium reticulatuni Al. Br.
