Knowlton, Frank Hall, Fossil Flora of the John Day 

 Basin, Oregon. (U. S. Geol. Surv. Bull. CCIV. 1902. 

 p. 1 — 113. 111.) 



The report details the results of work which has been in 

 progress for several years. A large number of new species 

 are described and figured. The flora is a rieh one, as now 

 known embracing 150 forms distributed among 37 families, and 

 it is especially notable for the large number of woody plants. 

 The distribution of families would be Dicotyledons 29; Mono- 

 cotyledons 3; Pteridophytes 3 and Gymnosperms 2, from which 

 it appears that the Dicotyledons maintained an enormous pre- 

 ponderance in the Vegetation of the region from which they 

 are now largely exeluded, and where the arborescent forms 

 have been reduced to scanty numbers, being represented along 

 the higher ridges by a few pines, along the lower ridges by 

 junipers and by a scanty fringe of cottonwoods and willows 

 along the streams. So far as may be determined from the 

 individual leaves, the Betulaceae is the dominant family, being 

 represented by Carpinus , Coiylus, Betula and Alnus. The 

 plants are all of Tertiary age, the oldest being Lower Eocene, 

 thence ranging upward to the Upper Miocene.

HOOKER, Sir J. D., A Sketch of the Life and Labours of 



Sir William Jackson Hooker. (Annais of Botany. 



Vol. XVI. 1902. No.LXIV. p. IX— CCXXI. With Portrait.) 



This aecount of the life of Sir William Hooker is at the same 

 time an excellent historical sketch of British Botany during the first half 

 of the last Century. The first chapter is devoted to an aecount of the 

 early days and the first portion of the career of the eminent botanist at 

 Nor wich and Halesworth (1785—1820). This is followed by an 

 aecount of the years, spent as professor of botany at Glasgow (1S20 

 — 1840). The third chapter describes the events which led to the appoint- 

 ment of Sir W. Hooker as Director at Kew and gives a sketch of 

 his work in this capacity, terminating with an aecount of his last days 

 (1841 — 1865). The appendices, which form a large portion of the work 

 include a catalogue of Sir W. J. Hooker's works with notes and obser- 

 vations, a Classification of the more important articies, contained in the 

 botanical Journals, edited by Sir W. J. Hook er, and finally a list of 

 some of his chief correspondents (1808 — 1865). F. E. Fritsch.
