. Fossil plants : for students of botany and geology . Paleobotany. 48 GESTKGOALES [CH. in China but the photographic reproduction is unfortunately too obscure to afford any indication as to the nature of the specimen. Baiera Phillipsi Nathorst. This Jurassic species^ (fig. 652) illustrates the absence of any definite dividing line between Baeira and GinJcgoites; it agrees very closely with G. sihirica and with leaves assigned to G. lepida and other 'species.' Fig. 652 is drawn frona PhilHps' type-speci- men^ which he named Sphenopteris longifolia and afterwards trans- ferred to Cydopteris; his specific name is not retained because Pomel adopted it for a type subsequently called by Heer Baiera longifolia^. Krasser records B. Phillipsi from Jurassic strata in Sardinia*. This species shades into B. gracilis and the very similar B. australis McCoy, especially resembling some leaves included by Halle^ in the latter species. Baiera Lindleyana (Schimper). Leaves of this type were first figured by Lindley and Hutton® as Solenites ? furcata and transferred by Braun to Baiera. Schimper' subsequently substituted Jeanpaulia and proposed the specific name Lindleyana on the ground that Heer had employed the designation furcata for a Rhaetic species of Baiera. Saporta included this species in Trichopitys. Baiera Lindleyana is characterised by the deep dissection of the lamina into very narrow, filiform, segments and by the presence of a long and slender petiole (fig. 653). Some forms of with rather broader segments are hardly distinguishable from Baiera Lha 652. Baiera Phillipsi. (York Musoum; * nat. size.) 1 Nathorst (80) A. p. 76. 3 Seward (00) B. p. 270.
