180 GLOSSARY. 



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). 



Bract. A modified leaf of the inflorescence. Several bracts form 

 an involucre. The seed-scales of cones in Pinaceae are in the 

 axils of bracts. 



Branch. One of the coarser divisions of a trunk or main stem : 

 loosely, any division of the stem. 



Bristly. With stiff hairs.

Bud. The undeveloped end or branch of a stem; usually referring 

 to the stage in which the growing tips pass the winter or dry 

 season ; also applied to undeveloped flowers or flower-clusters. 

 Winter-buds are usually scaly or protected by specialized re- 

 duced 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 (collateral) often in oak, silver 

 maple, etc. : or several buds may occur one above the other 

 (superposed) in ash, walnut, 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 (i in rhododendron, 3 in 

 elm) ; sometimes broken or aggregated in similarly placed 

 groups (buckeye, hickory), or consolidated in a crescent- or 

 U-shaped or elliptical series (ash) ; less commonly numerous 

 and irregularly scattered (oak). 



Calyx. The outer set of leaves of a flower. 



Canescent. Ash-colored, with fine close hairs. 



Capsule. A dry dehiscent fruit (rose-of-Sharon, mock-orange). 



Carpel. A simple pistil, or one member of a compound pistil.
