 author inclines to consider a modified sporangial annulus.

Heer's original description of the Bove}' Tracey lignite placed 

 the deposit in the Upper Oligocene or Lower Miocene, but this was 

 doubted by Starkie Gardner, who placed the beds in the Middle 

 Eocene, and this latter view has been generally accepted and 

 incorporated in the text books. The authors have visited the district 

 and collected much material of the seeds and other plant remains, 

 and have concluded that Heer's and not the later views, are more 

 nearl}^ correct. The foUowing species are described ordiscussed: 

 Magnolin atteniiata Weber (seeds), Vitis hookeri Heer (seeds), V. lud- 

 wigi AI. Br. (one seed), V. teiitonica (AI. Br.) (seeds), Cornus? mas- 

 tixia, n. sp. (fruits), Nyssa eiiropaea Unger (seeds), N. laevigata 

 Heer is considered a doubtful species, N. microsperma Heer, N. 

 obovata O. Weber (seeds), N. ornithohroma Unger (seeds), N. strio- 

 lata Heer, N. Verturnni Unger, Ruliiis tnicrospernins nov. sp., Cal- 

 varinus reticidatus nov. gen. et sp. Taxodmm distichum L. C. Rieh 

 (cone Scale), Seqiioia couttsiae Heer (cones etc.) Taxus haccata Linn. 

 (seed), T.? nüens (Heer) (seed), Stratiotes websteri (A. Brongn.), 

 Palmacites daemonorops (Unger) (fruits etc.), Calla cf. palustris Linn. 

 fseeds), Sagittaria n. sp. (carpel), Potamogeton temncarpus n. sp. 

 (fruits and germinated embryos). The lignites of Bovey show close 

 relationship with those of Wetterau, and if so, fiU a gap in the 

 geological sequence of Britain, for recent opinion has held that the 

 whole of the strata between Middle Oligocene and Lower Pliocene 

 were missing. The Bovey plants represent the top of the Oligocene, 

 and are also of interest for they show the gradual dying out of the 

 tropical Clements of the flora and incoming of a few northern genera.

Scott, D. H., Sporangia attributed to Botryopteris antiqtia 

 Kids ton. (Annais Bot. XXIV. p. 819-820. textfig. 1910.) 



In the lower Carboniferous sandstone flora of Pettycur, small 

 sporangia are commonly found associated with petioles of ßo^ryo/)^^n5 

 antiqua. Actual continuity between the petioles and the sporangia 

 has not yet been observed, but in the present note Dr. Scott figures 

 a group of four such sporangia and a petiole so closely associated 

 in such a manner that the whole arrangement appears unlikely to 

 be accidental. The sporangia have the characteristic multiseriate 

 annulus conspicuously well preserved, and are füll of spores. This 

 specimen heightens the probability that these sporangia, of Osmun- 

 daceous type, reall}'- belong to B. antiqua. M. C. Stopes.
