XLV] ARAUCAEITES ' 259 



Pleydelli from the Inferior Oolite of Dorsetshire, A. sphaericus 

 (Carr.)2, originally referred to Cycadeostrobus, and other species. 



Araucarites pippingfordensis (Ung.)* is a Wealden species first 

 described by Fitton and named by Unger Zamiostrobus pipping- 

 fordensis but recognised by Carruthers as a cone closely allied to A. 

 sphaerocarpus. Detached scales which may belong to this species 

 have recently been figured from the Wealden beds on the Sussex 

 coast. The cone described as Araucarites {Conites) sp. from the 

 same locality is possibly identical with A. pippingfordensis. 

 Araucarites Brodiei Carruthers. 



The specimens from the Stonesfield slate* on which this species 

 was founded are rather larger than the scales of A. Phillipsi : the 

 scale shown in fig. 740, 4, is 3 cm. long and 1-7 cm. broad; a raised 

 edge just beyond the single seed no doubt corresponds to the so- 

 called ligule on an Araucarian scale and the distal spinous process 

 is another feature shared with recent types. 



Araucarites (Sarcostrobus) Paulini (Fliche). 



A specimen described by Fliche ^ from Lower Cretaceous rocks 

 in the Haute-Marne, France, is made the type of a new genus 

 Sarcostrobus on the ground that the seeds are not so completely 

 covered by the tissues of the scales as in recent Araucarias. The 

 elliptical cone is 5-5 cm. long and 3-8 cm. in diameter; in form, 

 in the stout axis, and in the shape of the single-seeded cone-scales 

 it closely resembles the megastrobili of Araucaria excelsa and 

 Jurassic species such as Araucarites ooliticus (Carr.) (fig. 738) : 

 the small seeds are sunk in a cavity at the proximal end of the 

 scale, but Fliche states that they are not covered on their upper 

 side by the substance of the scale. He is no doubt correct in 

 assigning the cone to the Araucarineae, but the slight differences 

 between the relation of seeds to scales referred to by Fliche do not 

 appear to be sufficiently important to justify the creation of a 

 distinctive generic name ; moreover the preservation of the speci- 

 mens renders accurate description of details very difficult.
