1424. Baker, Edmund G., and C. E. Salmon. Some segregates of Erodium cicutarium 

 L'Herit. Jour. Botany 58 : 121-127. PI. 554. 1920.— Segregates of E. cicutarium fall into two 

 groups — those confined to sand dunes or similar places along the coast, and those growing nor- 

 mally inland. Only the coastal species are treated in this paper. A review of literature is 

 given, followed by a key to the British species. Synonomy, careful descriptions, references 

 to exsiccatae, and detailed notes on distribution are given for the five species treated. The 

 following species are considered. E. glutinosum Dumort., E. dentatum Dumort., E. neglectum 

 sp. nov., E. Lebelii Jord., and E. Ballii Jord. The plate contains illustrations of E. neglectum 

 and E. Lebelii. — K. M. Wiegand.

1426. Blake, S. F. Revision of the true mahoganies (Swietenia). Jour. Washington 

 [D. C] Acad. Sci. 10:286-297. 2 pi., 2 fig. 1920.— The taxonomic history of the genus 

 Swietenia, dating from the publication in 1743 of Catesby's "Natural History of Carolina," 

 is cited, and the five known species are described, one of these being added as a new species. 

 The most important of these commercially at the present time is probably S. macrophylla; 

 this species has largely replaced in commerce S. Mahogani, which was much valued earlier. 

 But much of the "mahogany" now on the market is from other genera than Sivietenia, often, 

 indeed, from widely separated families. Five species are recognized one of which, S. cirrhata, 

 is new to science. — Helen M. Gilkey. 



1427. Britton, N. L. Two new West Indian plants. Torreya 20 : 83-84. 1920.— Two new 

 species are described: Stenophyllus Harrisii from Jamaica and Croton Fishlockii from the 

 Virgin Islands. — J. C. Nelson.
