 quite correctly, to the plants now called 

 Dicotyledons. 



Exosporium. — The outer coat of the spore. 



Exserted. — Protruding, as stamens from 

 the throat of a corolla. 



Exstipulate. — Not possessing stipules.

 grain.

Farinose. — Covered with a mealy deposit. 



Fascicle. — A bundle. Applied to a com- 

 pact cyme, or to a compact cluster of 

 leaves. 



Fascicular. — Belonging to a bundle. The

 leaves, roots, etc. 



Fenestrate. — With large window-like per- 

 forations. 



Fertilization. — The form of sexual repro- 

 duction which consists essentially in the 

 union of two cells different in size and 

 appearance. 



Fibro-vascular Bundles. — The bundles 

 of stringy, vascular tissues of plants. 



Fibrous Tissue. — Elongated, thick-walled 

 and taper-pointed cells or cell derivatives, 

 found mainly in the fibro-vascular bun- 

 dles. The tissue includes bast cells, 

 wood cells and wood tracheids. 



Filament. — Literally, a thread. The term 

 applied to the stalk which supports the 

 anther. 



Filiform. — Thread-like. 



Filiform -apparatus. — The longitudinally 

 striated upper ends of the synergidae 

 which form a kind of cap projecting 

 through the upper end of the embryo-sac 

 in many plants. 



Fimbriate. — Fringed. Applied to certain 

 leaves, petals, etc., whose margins have 

 fine, fringe-like teeth. 



Fimbrillate. — Finely fringed. 



Fission. — That mode of cell division in 

 which the cell separates into two equal 

 or nearly equal portions. 



Flabellate, or Flabelliform. — Fan- 

 shaped ; applied to leaves, etc. 



Flagellate. — Producing slender runners. 



Flagellum. — A whip-like protoplasmic pro- 

 cess or large cilium which is attached to 

 some cells and serves as an organ of 

 locomotion. 



Fluviatile. — Belonging to, or growing in, 

 running water. 



Foliaceous. — Leaf-like. Applied to floral 

 organs, etc. 



Foliose. — Leaf-bearing. 



Follicle. — A monocarpellary pod that de- 

 hisces along the ventral suture only. 



Foramen. — The orifice in the coats of the 

 ovule through which the pollen-tube pene- 

 trates. Also applied to the corresponding 

 part in the seed. Same as Micropyle. 



Fovilla. — The contents of the pollen-tube. 



Frond. — A thallus, or organ in which the 

 functions of leaf and stem are not fully 

 differentiated. 



Frondose. — Thalloid, or like a thallus. 



Fructification. — The production of fruits 

 of whatever sort. 



Frumentaceous. — Belonging to grain. 



Fruticose, or Fruticous. — Shrubby. 



Fugacious.— Soon falling off. Applied to 

 certain sepals, petals, etc. 



Fuliginous. — Sooty-brown in color. 



Fulvous.— Having a tawny yellow color. 



Fundamental Tissues. — Those tissues of 

 the plant through which the fibro- vascular 

 bundles are distributed; they include all 

 the tissues, interior to the epidermis, not 

 included in the fibro-vascular bundles. 



Funiculus. — The same as pcdosperm. The 

 stalk of the ovule. 



Furcate. — Forked; divided into two equal 

 branches. 



Fuscous. — Grayish-brown. 



Fusiform. — Spindle-shaped; larger in the 

 middle and diminishing in diameter to- 

 ward either end. 



/"■ALBULUS. — A succulent, berry-like 

 cone, as the fruit of the Juniper. 



Galeate. — Shaped like a helmet. 



Gamete — ■ A sexual reproductive body, 

 either motile or non-motile, which by union 

 with another reproductive body, either 

 similar or dissimilar to it, produces a cell 

 which sooner or later develops into a new 

 organism. 



Gamogenesis. — A term applied to the pro- 

 cess of sexual reproduction.
