What reading level is On New Plants From the Erian And Carboniferous And On the Characters And Affini book?
To quickly assess the difficulty of the text, read a short excerpt:
They have apparently three nerves, but the lateral ones may be resin-vessels.
Mr. Bain also finds at St. Peter's Island, with the bran- ches and leaves of Tylodendron, the fruits or seeds represen- ted in Fig. 6. They appear to be wedge-shaped and in fours, and an involucre similar to that in Fig. C. Accompa- nies them, and is supposed to have oelonged to them, or possibly to male flowers of the same species. Neither of these organs have been found actually attached to the bran- ches. If these ...fruits belong to Tylodendron they would in- dicate taxine affinities, and they somewhat resemble the curious coniferous fruits from the Tertiary of Australia known as Spondylostrobus.
FIG. 6. Fruit and bracts of Tylodendron. (a) Fruit- (6) single seed, (c) bracts. (Drawn by Mr. Bain. ) Stems having the markings of Tylodendron occur in the Permo-Carboniferous of Cape John in Nova Scotia, and at that place there are also obscure Yoltzia-like leaves some- what resembling those of the Prince Edward Island specimens.
