244 REPORT — 1886. 



Coniferfe and Cycadece would be quite beyond our province, and it is only 

 those of the Cretaceous, as the last discoverable ancestors in our area of 

 the Eocene flora, that are of immediate interest. These belong, excluding- 

 Cycads, chiefly to the newest section of the Coniferfe, the Pine family. 

 "We are able to make the following contribution to our knowledge of 

 these : — 



Pinites Andrcei, Coemans. ' Flore fossile du Terrain Cretace du 

 Hainault,' 1866, p. 13, pi. v. fig. 1. Gault, Folkestone, fig. 1. 



This specimen measures 5 centimetres in length and nearly 3c. in 

 breadth, though something should be perhaps deducted for the compres- 

 sion undergone. When perfect it was probably composed of 50 to 60 

 imbricated leathery scales, about half that number being visible on the 

 exposed face. The substance of the scale seems to have been consider- 

 able, though the edges are thin ; they are smooth even without striae, and 

 with the upper margin round to obtusely pointed. They are apparently 

 variable in size. 



The cone is of the same general type as P. Andrcei, Coem., from the 

 Gault of La Louviere, Hainault, though somewhat shorter, more oval, 

 and with thinner and rounder scales. The form and general consistence 

 of the scales, as well as their size, the number composing each whorl,, 

 and their disposition are, however, so similar that we think it better, in 

 the case of so imperfect a specimen, to unite it rather than claim specific 

 rank on account of distinctions that might largely disappear with more 

 perfect specimens. If the assimilation is correct the apex of the cone, as 

 well as the base, would have been somewhat pointed. The cones are 

 very abundant at La Louviere, more than 100 specimens having been 

 collected ; and they are stated to have been frequently curved and highly 

 resinous. The specimen from Folkestone was found by us, being Tiniqu& 

 from that locality, and is now in the British Museum. 



Pinites Valdensis, sp. nov. figs. 4 and 5. Wealden, Brook Point, Isle 

 of Wight. 



This fragment shows the presence in the Wealden flora of a Pine of the 

 section Strobus with a cone composed of scales as numerous and thin as 

 in any recent species. The cone was long, cylindrical, and tapering, the- 

 scales very numerous, permanent, imbricated, leathery, pointed, and 

 lightly thickened at the apex, with entire margin, striated, and slightly 

 keeled. It somewhat resembles P. Dunkeri, Carr., also of the Wealden,. 

 but is probably a distinct species. The specimen, fig. 5, is from the 

 Tork Museum, and 4, in which all the scales are mutilated, from the 

 Woodwardian Museum. Both these, with several others, are frona the 

 Wealden of Brook, so that it appears to be by no means rare there. It 

 is associated with Cycadostrohus elegans, Carr., ^ a representation of which 

 is given for comparison in fig. 8. 



Pinites CaiTuthersi, sp. nov. Fig. 6. Wealden, Brook Point, Isle of 

 Wight. 



The fi-agment figured represents another long cylindrical cone with 

 very numerous persistent leathery imbricated scales. It tapers like the 

 one last described towards the base, the scales being much thicker, though 

 thin at the edge, smooth, without keel, and with entire rounded margins. 

 It resembles the Gault species P. Andrcei in texture, but there were at 

 least twice as many scales in each whorl, and these are much more 

 imbricated. It also is quite distinct from P. Dunheri, Carr.
