In North America tliis spprics is recorded 

 from the husal Eocene to tlie Pliocene and from 

 tlu> present recorded occurrence hi Mississippi 

 nortliwestward thron<;h th(> Kocky Moinitain 

 refjfion, on the Pacific coast, and along the shore 

 of the i\jctic, at the mouth of Mackenzie River, 

 and also in Gn^enJand. It is certainly not 

 al)undant in tlie Wilcox and is very sparsely 

 represented by tlie ty])ical terete twigs with 

 ap])ress(>d leaves and by seeds. No cones iiavc 

 been found in association witii it in the Wilcox 

 and it is possible that this occurrence may 

 represent the twigs of the same small tree repre- 

 sented by cone scales in M'ennessee tlnit I have 

 referred to Aj'throtaxis, which lias foliage that 

 is very similar to that of ( ily))tost robus. Since, 

 however, the foliage can not be difl'erentiated 

 from the abun(hint remains of Cllyptost robus 

 found elsewhere in America and Europe, where 

 the fruiting characters are kno^\ai, I have identi- 

 fied it as Glyptostrobus. Glyptostrobus con- 

 tains only two existing species, G. ]>ni<]iiltis 

 EntOicher and (/. hdiroplnjllus Endhcher, 

 which are small trees known as wat(n' ])iiies, 

 inhabitants of the low river bottoms of certain 

 parts of China. 



A multitude of small, irregularly fusiform, 

 inecjuilateral winged seeds are distributed 

 thi-t)ugh the clays at Early Grove, Miss. They 

 are about 5 millimeters long and 1..5 mOlimetei-s 

 m maximum width and have a curved oblique 

 nucleus near the broad end. They are not espe- 

 cially well preserved, being ferrugmous replace- 

 ments, but tliey are clearly of organic origin 

 and except for their slightly smtiHer size are in 

 exact agreement with the seeds from the Oli- 

 gocene of Schonegg in St^Tia referred by Et- 

 tingshausen ' to this species. Similar but still 

 larger remains occur in the Swiss Tertiary, 

 wliich Ileer - describes as seeds of Pterosper- 

 mites but which Ettingshausen is confitlent are 

 also seeds of Glyptostrobus. 



Occurrence. — Holly Springs sand; twigs from 

 raviiK! at Oxford, Lafayette Gounty, Miss. ; and 

 seeds from Early Grove, Mai-shall County, 

 Miss, (collected by E. W. Berry).
