Feb. 1907] PROCEEDINGS s. I. ass'n arts and sciences. 99 



This contribution may be reg-arded as supplementary to a previous 

 paper on "Affinities of Certain Cretaceous Plant Remains Commonly 

 Referred to the Genera Dammara and Brachyphyllum." reviewed in the 

 Proceedings of April 21st, igo6. Both of these papers are of special 

 interest to us, aside from their scientific value, for the reason that the 

 lig-nitic material upon which they were based was collected at Krei- 

 scherville and has been exhibited and discussed at several of our meet- 

 ing's during the past two years. 



The net results obtained by the author in his microscopic examin- 

 ation of Brachyphyllnvt are that the normal wood does not contain 

 resin canals but that traumatic resin canals, represented by amber- 

 filled interstices in the lignites, were produced as the result of wounds 

 or injury to the wood. In this respect the genus differs from the liv- 

 ing genera Dammara and Araucaria, although in other respects it has 

 a woody structure which is distinctly Araucarian. Lignites of this 

 latter type were obtained from the Drummond pit, however, which in 

 all probability belong to Araucaria or some closely allied genus.

II. Under the heading "Palaeobotanical Papers," in an unsigned 

 account of the meeting of the British Association for the Advancement 

 of Science at York, England, last summer, and published in the New 

 Phytologist, vol. v, 1906, pp. 177-188, may be found the following note, 

 on p. 186: "On Saturday morning [Aug. 4] a number of miscella- 

 neous papers were taken [before Sec. K., Botany], among which were 

 two important palaeobotanical communications." Of interest to us is 

 the fact that one of these, by Dr. E. C Jefifrey, on "The Structure and 

 Wound-Reactions of the Mesozoic Genus Brachyphyllum," in all 

 probability essentially the same as the contribution last reviewed, was 

 likewise based upon the Kreischerville material. This material aroused 

 great interest abroad and we are to be congratulated on having first 

 brought it to light and on having duplicate specimens in our museum 

 collection. 



The subject is also briefly mentioned in Nature, vol. Ixxiv, 1906, p.576.

The meeting then adjourned.
