44 DESCRIPTIVE CATALOGUE 



well as iu V. 8422. The section, however, is favour- 

 ably cut, and at the apex shows the base of the 

 micropylar extension. A neighbouring seed shows 

 the inner tissues of the seed, as well as the stone and 

 outer flesh, unusually well preserved. 



V. 8426. Oblique section (6x4 cm.) through cone and the 

 surrounding bracts. Most of the tissues are thick 

 and opaque. Some of the seeds are cut very tan- 

 gentially, so that the surface-view of the stone-layer 

 appears in small tessellated patches, as Carruthera 

 figures in his pi. lix, fig. 8. 



V. 8427. Figured by Carruthers, Trans. Linn. Soc. vol. 26 (1870), 

 pi. lix, fig. 5. Approximately transverse section 

 through a cone, cutting also bracts, leaf-bases, and 

 nimeuta, all of which are well preserved. In the 

 centre of the cone- section the seed-stalks are sur- 

 rounded by well-preserved interseminal scales. The 

 vascular bundles in the leaf-base are well preserve!, 

 and show their characteristic Cycad-like mesuich 

 structure very well. Sections of the multicellular 

 ramenta are also good. 



V. 8428. Figured by Carruthers, Trans. Linn. Soc. vol. 26 (1870), 

 pi. lix, fig. 4. Oblique section (3'5x2'3 cm.) of part 

 of a cone with eeeds, seed-stalks, and surrounding 

 bracts. The tissues are all blackened and opaque and 

 not very well preserved, but the embryos in the seeds 

 show particulaily well, as is indicated in Carruther?*' 

 drawings. The embryos are cut in different directions, 

 some nearly longitudinal and some in transverse 

 section. The seed at the top of the slide shows 

 particularly well the two cotyledons cut across, and 

 the indications of the single row of vascular bundles 

 remaining in each. 



V. 8429 a. Figured by Solms-Laubach, Bot. Zeit. 1890, pi. x, 

 figs. 1-4, & Ann. Bot. 1891, pi. xxvi, figs. 1-4. A 

 much broken section similar to the above, in which 

 little but the seeds remain. In them the transversely 

 cut cotyledons of the embryos show verv well.
