258 BOTANICAL GAZETTE [MARCH 
Fodder and pasture plants.—At times it is difficult for the student of agri- 
culture to obtain at once adequate botanical descriptions and cultural data of 
plants commonly used for fodder and pasture purposes, while the farmer is 
frequently poorly informed upon either phase of knowledge relating to the 
plants he is constantly growing. A recent volume by CLARK and MALTE: 
seems to be particularly well fitted to meet the needs of both student and farmer. 
Its botanical descriptions of the grasses and clovers usually cultivated are 
accurate but non-technical, while in addition it furnishes abundant data upon 
the geographical distribution, cultural conditions, habits of growth, and agri- 
cultural value of the plants discussed. Perhaps the best feature of the volume 
is the admirable series of colored plates depicting the species described with 
such accuracy that any one, even without botanical training, can have no 
difficulty in at once recognizing them. In this respect the volume is uniform 
with the Farm weeds of Canada previously noticed in this journal,‘ and it will 
form a valuable addition to the equipment of the teacher of agriculture as well 
as a convenient book of reference for the farmer—Gero. D. FULLER. 
Ferns of Washington.—Under this title Frye and Jacksons have pub- 
lished a small book which is a boon to those who wish to become familiar with 
the ferns of Washington. It includes the true ferns, water ferns, adders- 
tongues, grape ferns, horse tails, scouring rushes, club mosses, moss ferns, and 
quillworts. The writers find 66 species of pteridophytes in the state, of which 
30 are Polypodiaceae. These species belong to 24 genera, of which 16 are 
Polypodiaceae. The work has a key to families, and keys to the genera and 
species. The families, genera, and species are all described. The habitat and 
the range of each species is given. In a state comprising such a diversity of 
regions as does Washington, the distribution within the state would add to 
the usefulness of the work. It is illustrated with 20 plates made from draw- 
ings and photographs, illustrating the principal species treated in the work. 
This publication will undoubtedly add greatly to the interest in the ferns and 
their allies in the Northwest.—GrorGE B. Rice
