on our local flora by Mr. Norman Taylor, a work likely to 
prove of exceptional interest and value among local floras. 
Besides these complete works, many papers have been 
contributed in the publications of the Torrey Botanical Club 
and elsewhere. 
The most important exploration of the year was one of 
some three months’ duration, made in the West Indies by 
our Director-in-Chief, compel by Mrs. Britton and 
Mr. J. A. Shafer. Dr. Britton, accompanied by Mr. 
Stewardson Brown, also spent some time in Bermuda. 
These two expeditions were conducted with a view to closing 
up certain gaps which existed in our knowledge of the flora 
of the regions visited. For a similar purpose, Dr. Small 
made two visits to Florida. 
In this connection, reference should be made to a visit 
of Dr. Murrill to European herbaria for studies necessary in 
the preparation of his portion of the Norra AMERICAN 
LORA. 
Laboratory and culture work by and under the direction 
of Dr. Stout has been in the general direction of heredity and 
variation in plants, and has been very actively pursued. 
Special studies have been made in bud-variation, as illus- 
trated in Coleus, biotypes in Hibiscus, the influence of 
repeated crossings in Verbascum, and variations in inherit- 
ance in chicory. 
Twenty-two students have pursued regular lines of work 
in the Laboratory. Although this work covers a variety of 
subjects, it has a strong general bearing on Dr. Stout’s 
individual studies. The following are the more important 
of these subjects: Heredity in Phaseolus, Aquilegia and 
Phlox, fertilization in a lupine, the relation of the shapes of 
cells to that of the organ containing them, the mosaic 
disease of tobacco, the genera Bryum, Marasmius, Digitalis, 
and Vernonia, plant pathology and paleobotany. Mr. 
Gleason’s paper on Vernonia is worthy of special mention. 
Not only does it contribute knowledge of many new species 
but it also places the general nature of this large and difficult 
genus before us in a better light.
