and the megasporophyll. The sporange is relatively large, with a 

 Short cylindrical pedicel, which closed in the ligular groove. These 

 microsporophylls are compared and distinguished from those in 

 Bothrodendroii tniniduni. 



The affinities of Miadesmia are discussed with the conclusion 

 that it belongs to the ligulate Lycopodineae. Is is compared with 

 Lepidocarpo)i and Isoetes especially in regard to the velum. Miadesmia 

 is regarded as unique among the Lycopodineae, so far known, in 

 retaining an absolutely cr3^ptogamic type of microsporophyll. while 

 it has advanced to a high degree of elaboration of the megasporo- 

 phyll, Analogous cases are found among the Pteridosperms and in 

 all Phanerogams. The aggregate of characters corroborates Ber- 

 trand's view that Miadesmia is nearly allied to Selaginella.

Berry, E. W., A Mid-Cretaceous Species of Torreya. (Amer. 

 Jour. Sei. (IV) XXV. p. 382-386. f. 1—3. 1908.) 



The author describes a new species of Torreya, Tiimion caro- 

 liniamim., from the Cretaceous BladenJ formation of the coastal piain 

 of North Carolina. The material, in addition to its great resem- 

 blance to the modern species of Tiimion in general appearance and 

 characters, shows the two ventral stomatal bands which characterize 

 that genus. The distribution of the living and fossil forms is dis- 

 cussed and the conclusion isj reached that Tiimion is a type of relati- 

 vely great antiquity, with a primitive structure and that a few cen- 

 turies will probably see its extinction. Berry. 



Berry, E. W., Some Araucarian remains from the Atlantic 

 coastal piain. (Bull. Torrey. bot. Club. XXXV. p. 249—260. 

 pl. 11- 16. 1908.) 



This paper illustrates the unexpected abundance of the Araii- 

 carieae during the Cretaceous in Eastern North America. A large 

 cone, Araucarites Zeilleri, is described Ifrom the Magothy formation 

 of New Jersey. From the South Atlantic coastal piain two species 

 are described. One of these, Araucaria hladenensis , is based on 

 foliage which is very similar to the modern Araucaria Bidwilli and 

 occurs at no less than fourteen localities in North Carolina, one 

 in South Carolina and one in Alabama. The other, Araucaria 

 Jeffreyi, is based on large single-seeded cone-scales which are verj'^ 

 abundant in the same strata which contain the twigs of Araucaria 

 bladenensis and while not so widespread as the latter are recorded 

 from no less than live different localities in North Carolina. 



The distribution of the Araiicarieae both in the Cretaceous and 

 and Modern floras is discussed and graphically illustrated by small 

 maps. Berr)'. 



Cockerell, T. D. A., Descriptions of Tertiary Plants. (Amer. 

 Jour. Sei. (IV). XXVI. p. 65-68. f. 2. 1908.) 



In continuation of the author's previous studies brief descriptions 

 are given of the following new species from the shales at Floris- 

 sant, Colorado: Lininohium ohliteratum , Acer perditiin^ and 

 florigerum , Phaca wilmattae , Hydrangea florissautia. 



The age of these beds, usuall}^ regarded as Oligocene, is stated 

 to be Miocene. Berry.
