OF LOWER GliKKNSAM) I'LAXTS. 4") 



V. 8429 b. A much blackened and opaque section of a leaf-base 

 and part of a cone (5 x 2*5 cm.). 



41388 a. A much blackened and partly disintegrated section 

 (Trf) x 3'5 cm.) of an oblique cut through part of two 

 cones, bracts, etc. 



41388 b. A section of part of a cone and bracts (5 g 5x2 cm.). 

 The testa and bract tissues are well preserved ; 

 one of the seeds is cut in nearly median longitudinal 

 section, and shows both the basal vascular strand and 

 the micropylar regions remarkably well. 



41388 C. A section of opaque fragments (2 x 3 cm.) with two 

 poor seed-sections at one side. 



41388 d. A small section with a few seeds in which the em- 

 bryonic and seed- coat tissues arc well preserved. 



The last four slides cut from four small pieces numbered 

 41388. 



V. 13205, 13206. Two large sections, 11x7 cm. in area, showing 

 the wood etc. of the main axis and several leaf-bases, 

 ramenta, etc. The tissues are well preserved and the 

 sections thin. Cut from block V. 13203. 



All the above series of slides are from the type-specimen 

 of B. Gibsonianus, and have been transferred from the Botanical 

 Dept. from time to time without special histories. 



The following blocks have had sections cut from them : 

 V. 6140. A small slice (3 - 5 x 2 cm.) from the middle of a cone. 



V. 6317. Two larger and three very small scraps of leaf-bases 

 and seeds. 



V. 5708. A small irregular piece of leaf-base and obliquely cut 

 cone, from which slide V. 8410 was cut. 



41388. Two larger and two very small irregular fragments, 

 from which slides 41 338 -d were cut.
