207. ZoN, Raphael. The outlook for extending American lumber trade in Italy. Jour. 

 Forestry 18:723-730. 1920. — Prior to the European war, the Italian forests were being 

 greatly overcut in spite of heavy importation from other countries. During the war, the 

 home forests were badly depleted and injured by indiscriminate and heavy cutting. Italj' 

 now finds herself with new provinces with new sources of wood supply; but with the need 

 of recuperation in her own forest area and the increased demand, Italy will need much addi- 

 tional lumber. The price of lumber in America and the prevailing exchange rates prevent this 

 country from furnishing much of a supply; but the new countries around the Mediterranean 

 should be able to supply much of the demand. — E. N. Munns.

208. Almquist, Ernst. Studien iiber Capsella bursa-pastoris (L.). II. [Studies on 

 Capsella bursa-pastoris L. II.] Acta Horti Bergiani 7: 41-95. 16 fig. 1921. — Describes 

 200 species of Capsella bursa-pastoris based on the constancy of differentiating features when 

 grown for two or three generations in the experimental garden. Unlike the author's earlier 

 study in this genus, in which the classification was based chiefly on foliage characters, the 

 forms described in the present paper are distinguished chiefly on the basis of form and size 

 of capsules. The author notes that some natural crossing occurs, and promises a further con- 

 tribution dealing with crossing and mutation in this genus. He groups the species into twelve 

 classes, named as follows: (1) Concaviformes, (2) Scolioticae, (3) Ruhelliformes, (4) Corculatae, 

 (5) Cordatae, (6) Otites, (7) Cuneolatae, (8) Triangulares, (9) Heterocarpae, (10) Lanceolatae, 

 (11) Convezae, (12) Hiantes; but these groups are not described and the figures do not allow 

 a clear conception of their differentiating features. Capsella apeiala Opitz, C. integrifolia 

 Retzius, and C. pinnatifida Schlechtendal are found to occur associated with very diverse 

 characters belonging in different groups. These are therefore not species nor constant varie- 

 ties but mixtures of forms having different natural affinities. — Geo. H. Shull.

 peas, sun flowers, etc., and this firm is stated to have one of the largest botanical collections of 

 peas in existence. — J. M. Shull.
