TYPE. A single, large, petrified trunk which was early 

 broken up and distributed (see p. 40). The following numbers 

 in the Geological Department of the Museum are all parts of 

 it --(slides) V. 13205, 6, V. 8398, V. 8:399, V. 8400, V. 8401, 

 V. 8406, V. 8410, V. 8422, V. 8425, V. 8426, V. 8427, V. 8428, 

 V. 8429 a-6, 41338 a-4 1388 c ; (blocks) V. 6140, V. 6137, 

 V. 5706, 41388, V. 13203 4. 



There are also three pieces, one finely polished, in the 

 Botanical Department of the Museum. Other pieces are at 

 Kew. 



Dr. D. H. Scott has in his collection slides 350-55 and 

 357-364, cut from the type block at Kew, and Count Solms- 

 Laubach has a similar set cut at the same time from the 

 same piece *. 



Dr. Wielandhas some sections of the seeds of the typo which 

 he has cut himself, and there are p.^.siblv other portions of the 

 type-specimen in private hands.

DESCRIPTION. The trunk ruthers (1^7<>) 



as having been S ins. lonir, but incomplete at both ends. 11 

 is somewhat' compressed, the transverse section being oval, 

 measuring 11 x 0'5 ins. The fructifications were approximately 

 ripe at the time of petrifaction and may be described as fruits 

 rather than " flowers." 



The pith is 1 in. in diameter according to Carruthers ( 1>7<>, 

 p. 700). This is oval, and in the surface of the block now 

 available measures 1<> x 2--~> em. Carruthers describes it as being 

 " composed of large subspherical cellular tissue, free from sepa- 

 rate -woody bundles, hut penetrated everywhere with gum 

 canals.'' F/xcept near the edge o!' the pith, where it is pene- 

 trated by the protoxylem groups, the cells are largely macerated 

 and disorganised, so that a brownish mulch, penetrated by large 

 and irregular gum-canals, is all that can be seen in some sections. 



* Count Solms-Lauhach ha* a second specimen (see p. 40) found by 

 Dr. Leeson. ai:d from this sections were cut from a part given to Dr. Scotl 

 in 1001 (Scott Coll. nos. 159!)-1611). This is not a part of the type- 

 specimen, nor is it a co-type, but it is oi' interest because of the rarity of 

 the form.
