In order to secure a more complete knowledge of anther and p dlen formation in tins family, 

 60 species belonging to 40 genera were studied. Brief note is made of the method of devel- 

 opment of the pollen sacs, the pollen mother cells, the "nourishing tissues" and the anther 

 walls. The reduction division forming the pollen grains is not different from that found in 

 other plant groups. — V. II. Young. 



340. Rosendahl, C. O. Variations in the flowers of Erythronium propullans Gray. 

 Torreya 19:43-47. Fig. 1-3. 1919. — The stamens in this very local species show marked 

 heteromorphism, those of the outer whorl averaging 6.32 mm. in length, of the inner 7.99 

 mm. Considerable variation in the size of the anthers is also noticed, but unrelated to the 

 filament-length. The number of perianth-segments varies from 6 to 4, of stamens from 6 to 2. 

 In the trimerous flowers the ovary is 3-celled, in the tetramerous 2-celled. The flowers are 

 smaller than in any other species of the genus, probably due to a diversion of food-supply 

 into the offshoot. — J. C. Nelson.
