370 Glossary 



Fissured. Torn lengthwise, as applied to bark, or to pith, 

 for which the more general term spongy is used. 



Fistulous. Hollow, with excavated pith (honeysuckle stem). 



Flaking. Shredding, but with short fragments. 



Fleshy, or succulent. Not hard and woody (stem) ; not dry 

 (fruit, bud-scales). 



Floriferous, florigerous. Flower-bearing, or producing flowers. 



Fluted. Corrugated or ridged lengthwise. 



Foliage. Collectively, the leaves of a plant: the green ex- 

 panded organs in which carbon from the air is combined 

 into organic compounds. 



Foliage-sprays. Twigs that finally fall away carrying the 

 small leaves with them, sometimes at end of the first 

 season (tamarisk), sometimes after several years (arbor 

 vitae). 



Foliar-gaps or lacunae. Breaks between the vascular bundles 

 of the stem which run continuously from one internode 

 into another. Through these breaks certain bundles of 

 the stem pass out into the leaves to constitute the net- 

 work of veins through which these organs are supplied 

 with water absorbed by the root and conducted to them 

 through the stem. An admirable illustrated paper on the 

 anatomy of the node as an aid in the classification of 

 angiosperms is published by Sinnott in The American 

 Journal of Botany for July 1914. 



Follicle. A small dry fruit opening down one edge (nine- 

 bark). 



Fragmented. Not continuous, as applied to bundle-traces. 



Fringed. Ciliate with glands or scales rather than fine hairs, 

 as here used. 



Fusiform. Spindle-shaped (buds of beach). 



Gametes. Sex-cells: egg and sperm. 



Gamophyllous. Of united leaves; gamopetalous when these 

 are petals, gamosepalous when they are sepals.
