Basal, or radical. Leaves that are clustered near the ground. 



Berry. A fleshy fruit, usually small. 



Bipinnate. Twice, or doubly, pinnate. 



Bladdery. Thin-walled and much larger than the seeds (fruit 

 of the bladder-nut). 



Blistered. With elevations filled with resin (bark of fir).

 er-clusters. Winter-buds are usually scaly or protected by 

 specialized reduced leaves or their parts, but sometimes 

 naked when their outer envelopes develop into leaves in 

 the spring. Though normally one occurs in each leaf-axil, 

 this is accompanied by an accessory bud at each side (col 

 lateral) often in oak, silver maple, etc.: or several buds 

 may occur one above the other (superposed) in ash, wal- 

 nut, Kentucky coffee tree, etc., with the uppermost of the 

 series largest; or in honeysuckle, where the lowermost is 

 largest. 



Bunched. Polyadelphous or in several tufts (stamens of 

 linden). 



Bundle-traces. The broken ends as seen on the leaf-scar of 

 woody strands passing from the stem into a leaf: often 

 simple and definite in number and position (1 rhododen- 

 dron, 3 in elm) ; sometimes broken or aggregated in simi- 

 larly placed groups (buckeye, hickory), or consolidated in 

 a crescent- or U-shaped or elliptical series (ash) ; less 

 commonly numerous and irregularly scattered (oak).
