complete restoration may be made. Ginkgo pusilla and Sequoia 

 langsdorfii were previously known to this horizon through 

 their foliage and fruit, but they are now found in the Upper 

 Cretaceous in the form of stem fragments in which the structure 

 is well preserved. Sequoia langsdorfii is of special value, 

 inasmuch as it serves to give a more important means of com- 

 parison with the existing 6". sempervirens with which it has 

 always been connected. The wood shows that there is no 

 essential distinction between the two, and the one must be 

 regarded as the fossil form of the other. 



The plants from the Red Deer River embrace several well 

 known forms including Sequoia nordenskioldi and 6 1 . couttsiae ; 

 Taxodium distichum miocenum and Giyptostrobus europaeus ; 

 and a few new species. Among these latter are Majanthemo- 

 phyllum grandifolium, represented by a leaf of unusual size 

 but strikingly like that of Maianthemum bifolium ; Clintonia 

 oblongifolia and Viburnum ovatum. The evidence of the flora 

 confirms the opinion expressed by Tyrrell, that the Paska- 

 poo series is of Eocene age. 



Only a few specimens were obtained from the Horse-Fly 

 River, but they include an important representation of Coni- 

 ferous plants. Giyptostrobus europaeus, Taxodium distichum 

 miocenum and Sequoia langsdorfii are represented by foliage 

 and fruit. Pseudotsuga is for the first time found in a fossil 

 state, and it is here represented by well preserved wood which 

 is strikingly like that of the modern P. douglassi which it 

 may eventually prove to be. Pinus trunculus, described by 

 Sir William Dawson in 1890, once more appears in 

 characteristic form. The formation appears to be Miocene.

PENHALLOW, D. P«, Osmundites skidegatensis. (Trans. R. 

 Soc. Canada. VIII, IV. 1902. p. 3—30.) 



Describes a new species of Osmunda from the Lower 

 Cretaceous of Skidegate Inlet, Queen Charlotte Islands. 

 The material presented was in the form of exceptionally well 

 preserved and calcified stems, and a few fragments of fronds. 

 Comparisons are made with existing Osmunda s and with Todea 

 barbara. While approaching the latter in a few structural 

 features, it is most like the true Osmunda's, and the charactcr 

 of the foliage seems to make it most nearly like O. clay- 

 toniana. It" appears to have been about eight times larger 

 than any existing species, but with the habit of a true 

 Osmunda. D. P. Penhallow.

(U. S. Bureau of Forestry Bull. XXXVII. p. 1—58. 1902.) 



Part. 1, by Mr. Hall, treats of the cultural characteristics of the 

 catalpa. Of the trees used for commercial planting none other has been 

 more extensively planted in the Middle West. The studies were made
