lower ground from central Colorado and Utah to the borders of Texas 
and Mexico. It is the ©. alba var. gunnisoni of Torrey, the Q. 
douglasii var. gambelii of A. DeCandolle, and the Q. undulata var, 
gambelii of Engelmann. 
Of the remaining species the most notable are Q. chrysolepis Leib- 
mann and Q. densiflora Hook. and Arnott, the latter evidently re- 
lated to the chestnut (Castanea), both in foliage and fruit. The former 
enjoys the distinction of being ‘‘ the most valuable oak of the Pacific 
forests." Like many other western species, it has passed under several 
other names, viz., Q. pulvescens Kellogg, and Q. erassipocu/a Torrey. 
The second part of the work contains plates of ten species and 
varieties never before figured. It is a supplement to the work of the 
lamented Kellogg, and is most fittingly added to it. The newly-figured 
species are: Q. palmeri Engelm., Q. Zurbinella Greene, Q. tomentella 
Engelm., Q. macdonaldi Greene, and its variety elegantula Greene, 
Q. fendieri Leibmann, Q. jacobi R. Brown Campst., ©. gilberti 
Greene, Q. venustula Greene, Q. dumosa forma polycarpa Greene.—

The Flora of Nebraska.—Nebraska has an interesting flora. 
Its geographical position, stretching from the mountains on the west 
across the arid plains to the rich prairies on the east, and a midway 
latitude between north and south, is strong indication of the fact. 
The well-known catalogue of Nebraska plants by Samuel Aughey, 
published fifteen years ago, upon data now known to have been sadly 
defective, contained such a wealth of plant names that it has led 
botanists ever since to believe in the superior richness of the flora. 
The really earnest and careful study of the State flora dates from 
the connection of Professor C. E. Bessey with the State University at 
Lincoln. Upon his entrance into the State the collection of a repre- 
sentative herbarium was begun, together with a study of the economic 
features of the vegetation. Valuable papers upon different portions of 
the work have been published from time to time, the latest of which is 
given in the Annual Report of Nebraska State Board of Agriculture 
for 1889, recently issued. 
This paper is the official report of the botanist to the board, and 
covers 160 pages. The first part is an account of the grasses and 
forage plants of Nebraska, in which many practical suggestions and 
comments are introduced. So far 106 native species are known within 
the State, and 22 kinds that have been introduced as weeds. The
