This author has recently described a specimen from Jurassic rocks in Transbaikalia as Pin- ites [Pityofhyllum) cf. P. kobukensis^. Similar though smaller specimens Re- 777. Pityodadus kobuken- of Abietineous short shoots are de- scribed by Nathorst* as Pinites (Pityo- dadus) spp. a and b from Upper Jurassic beds in Spitzbergen, and compared by him with Pityites Solmsi. PITYOFHYLLUM. Nathorst. This name^ is applied to detached leaves of needle-like form like those of recent Pines or to long linear leaves broader and flatter than the needles of Pinus. Some of the specimens referred to this genus are very similar to the leaves of Keteleeria. In a few cases (fig. 775) the leaves are still attached to a short shoot but usually they occur as detached specimens (fig. 776). The genus is met with in Rhaetic strata but is specially abundant in Jurassic floras and persists through Cretaceous and Tertiary rocks. The leaves generally described under this generic term are broader and flatter than such leaves as those of Pityites Solmsi^ and recent 1 Ettingshauspn (52) B. PI.
