Description. — Twigs slender, bearing dimor- 

 phic foliage. One form carries short tliick 

 appressed leaves, the other acute spreading 

 slender leaves. Male catkins ovate, single, 

 sessile on latertd shoots; scales few. Cones 

 ovate, relatively large; scales narrow, imbri- 

 cated, cuneate at the base, summits expanded, 

 semicircular, with obtusely dentate margins, 

 the dorsum more or less longitudinally costate; 

 seeds inequilateral, winged. 



Glyptostrobiis europxus is one of the most 

 interesting Tertiary plants. It was discovered 

 nearly a century ago by Brongniart and has 

 been identified from many horizons in Europe, 

 Asia, and .^Vmerica. That it was a cosmopoli- 

 tan type can not be doubted, for the present 

 distribution of the Taxodiete is in itself a suffi- 

 cient indication of this. I have given above a 

 partial synonymy, which must be used witli 

 caution, since it is very probable that several 

 closely related species are inextricably tangled 

 in it, 1)11 1 tlie problem can not bo satisfactorily 

 settled without actual specimens from a very 

 large nimiber of localities.
