 ficance. (Torreya. XIV. p. 39—42. pl. A, B. 1914.). 



Discusses the arrested development of the terminal leaflets of 

 pinnate leaves in Rhus Powelliana Lesq., and R. Uddeni Lesq., 

 from the Dakota sandstone (Upper Cretaceous) in Negiindo triloba 

 Newb., and Sapindus membranaceits Newb., from the Fort Union 

 group (Lower Eocene), and in Saphidopsis variabilis Font., and S. 

 magnifolia Font., from the Patapsco formation (Lower Cretaceous).

 Dublin Soc. XIV. n. s. 9. p. 169—178. pl. 10—12. 1914.) 



A Psyginophyllum-Vike leaf Impression from the Upper Devonian 

 of Kiltorcan is described as Ginkgophyllurn kiltovkense, sp. n. 

 The lamina is dichotomously divided, and the venation is also di- 

 chotomous. The specimen is considered to be almost certainl}^ a 

 member of the Ginkgoales. Some associated fragments of stems may 

 belong to the same species. \V. N. Edwards.

 maria and Cone. (Sei. Proc. Roy. Dublin. Soc. XIV. n. s. 13. 

 p. 211—214. pl 14—18. 1914.) 



An Impression of Bothrodendvon kiltorkense was recently found 

 at Kiltorcan showing at one end typical leaf-scars and at the 

 other scars of Stigmarian appendages, thus proving that Stigmaria 

 was the Underground organ of Bothrodendvon as well as Lepidoden- 

 dron and Sigillavia. 



Further material shows that the cone of this species was 

 stalked, and bore megasporangia below and microsporangia above.

 sp. (Sei. Proc. Roy. Dublin. Soc. XIII. n. s. 34. p. 500-528. pl. 

 35-41. 1913.) 



The auhtor describes specimens of Bothrodendron kiltorke)ise 

 from the type locality in Ireland, with a resume of previous 

 work on the plant and on the Upper Devonian beds in which it 

 occurs. The stem was dichotomously branched and bore tufts of 

 linear leaves. The leaf scar and the external characters of the stem 

 are described in detail, and the calaraitoid appearance of some stems 

 is noticed. The strobilus and Stigmarian appendages are also described.

Knowlton, F. \\., The Jurassic Flora of Cape Lisburne, 

 Alaska. (U. S. Geol. Surv. Prof. Paper. LXXXV D. p. 39—64. 



pl, 5—8. 1914.) 



The author describes a very interesting flora of middle Jurassic 

 age from the Corwin formation of Cape Lisburne, Alaska 

 which is found in association with numerous well developed coal 

 seams. Seventeen species are described, the following genera bcing 

 represented: Conioptcvis, Cladophlehis, Eqiiisetum, Podo.zamites, Oto- 

 .'^aniites, Zamites, Phoenicopsis, Elatides, Pagiophyllum , Pitiophyl- 

 liim, Fieldenia and Ginkgo. All of these are well known Jurassic
