seed ferns: Cycadophyta or cycads and their extinct relatives: Coniferophyta, which corre- 

 spond almost precisely with the Gymnospermae of the older students: and Angiospermo- 

 phyta which comprises the so-called flowering plants. — E. W. Berry. 



1603. Berry, E. W. Geologic history of the locust and its allies. Plant World 21: 284- 

 298. 26 fig. 1919. — A popular account of the geological history and former distribution of 

 the genera Robinia, Gleditsia, Gymnocladus and Cercis illustrated with numerous figures of 

 fossil forms. — E. W. Berry.

 ica and the adjacent regions. Geol. Soc. Amer. Bull. 29: 631-636. (1918) 1919.— Summarizes 

 our knowledge of the Tertiary floras of South America and southern North America, con- 

 cluding that the Mesozoic and early Tertiary radiation of the flowering plants was from the 

 Northern Hemisphere over well defined land connections with South America, and that 

 there was a free interchange of forms in the Oligocene, Miocene and Pleistocene. — E. W. 

 Berry. 



1605. Berry, E. W. Age of certain plantbearing beds and associated, marine formations in 

 South America. Geol. Soc. Amer. Bull. 29:637-648. (1918) 1919.— Summarizes existing 

 knowledge of the Tertiary floras of Panama, Colombia, Ecuador, Peru and Chile and pro- 

 poses tentative correlations of these with marine formations in this general region and also 

 with Patagonia and Antarctica, discussing their bearing on the geological history of the 

 western part of the continent. — E. W. Berry. 



1606. Berry, E. W. Miocene fossil plants from northern Peru. Proc. U. S. Nation. 

 Mus. 55:279-294. PI. 14-17. 1919. — Describes the geology and fossil flora found in the 

 coastal region of northern Peru south of Tumbez. The following plants are described from 

 beds of early Miocene, probably Burdigalian, age: Iriartiles tumbezensis n. gen. et sp., Steno- 

 spermation columbiense Engelhardt, Bambusium Stubeli Engel., Ficus Winslowiana n. sp., 

 Guatleria culebrensis Berry, Amona Winslou-iana n. sp., Banisteria incerta n. sp., Trigonia 

 varians Engel., Vochysia retusidolia Engel., Tapirira lanceolata Engel., Mespilodaphne tum- 

 bezensis n. sp., Persea macrophylloides Engel., Styrax lanceolata Engel., Condaminea grandi- 

 folia Engel. It is shown that in early Miocene times a tropical mesophytic flora occupied the 

 present coastal desert region, from which it is concluded that the Andes had not been ele- 

 vated at that time or that the Humboldt current did not occupy its present position. — E. 

 W. Berry.

 Paper 125: 1-9. 2 fig., pi. 1-13. 1919. — Describes a basal Eocene flora from the Barilla 

 Mountains in western Texas. Species described are Sabalites grayanvs (Lesq) Berry, Geo- 

 nomites visianii n. sp., Juglans rugosa Lesq., Asimina eocenica Lesq., Ilex barillensis n. sp., 

 and Oreodaphne pseudoguianensis Berry. — E. W. Berry. 



1608. Campbell, D. H. The derivation of the flora of Hawaii. 34 p. Stanford Univ., 

 California. 1919. — An extended discussion of the regional relationships of the Hawaiian 

 flora and summary of the faunal evidence of all the great groups so far as known. The author 

 concludes that the liverworts and filmy ferns afford especially conclusive evidence, which is 

 supported in a greater or less degree by evidence derived from other plant groups and the 

 fauna, that the bulk of the Hawaiian flora was derived from the South Pacific region, and 

 that this derivation cannot be satisfactorily explained except by the assumption of a more 

 or less direct land connection in former geologic times. — E. W. Berry.
