FLO 



Floral. Of or belonging to the flower. 

 Floral envelopes, the calyx and corolla, 

 one or both. 



Florets. When many small flowers are col- 

 lected in clusters or heads, each flower is 

 called a floret. The florets of the disk 

 are those which occupy the center of the 

 head of a Composite; while florets of the 

 ray occupy the circumference. 



Florifer. Flower bearing. 



Floriparous. Producing flowers. 



Florist's Flowers. "Flowers which, by their 

 beauty or fragrance, power to produce 

 permanent varieties, and facility of culti- 

 vation, are so largely in demand as to 

 render them especially worthy of cultiva- 

 tion as an article of comm erce. " The term 

 is most generally applied to flowers that 

 have " broke " from the original species 

 into varieties, such as the Dahlia, Ver- 

 bena, Pelargonium, Gladiolus, etc., in 

 distinction from such plants as still hold to 

 their natural condition without variation. 



Florus. In composition is equivalent to 

 flowered; thus, uniflorusis one-flowered; 

 biflorus, two-flowered; triflorus, three- 

 flowered; multiflorus, many-flowered. 



Flos. A flower. 



Flosculi, (adj. Flosculose.) The same as 

 florets, which see. 



Flower. That assemblage of organs in a 

 plant, of which the stamens or pistils, or 

 both, form part. 



Flues, single and double. See Heating. 



Fluitans. Floating on the surface of water. 



Fluvial, Fluviatile. Of or belonging to the 

 water. 



Fwmineus. Female, bearing pistils only. 



Foliaceous. Having the form of leaves. 



Foliage Plants. A popular term, though an 

 incorrect one, given to distinguish such 

 plants as are used for decorative pur- 

 poses, for the beauty of their foliage 



FOV 



rather than for the beauty of their flowers. 

 It is more particularly used for such 

 plants as are used for massing in color; 

 for example, the Achyranthes, Centau- 

 reas, (Dusty Millers,) Pyrethrum aureum, 

 (Golden Feather,) Coleus, and plants of 

 that class used in " ribbon line " bed- 

 ding, are called " foliage " plants; though, 

 among plants for inside decoration, the 

 Crotons, Dracaenas, Pandanus, Fancy 

 Caladiums, etc., are sometimes so named; 

 but the proper designation for all such 

 plants, whether used for outside or in- 

 side decoration, is " Ornamental-leaved 

 Plants," or " Ornamental-foliaged Plants." 



Foliar. Inserted upon, or proceeding from, 

 the leaf; thus a cirrhusfoliaris is a ten- 

 dril growing from a leaf. 



Foliate. Clothed with leaves. 



Foliation. The act of leafing; the period 

 when the buds begin to expand. 



Foliiparous. Producing leaves only, as leaf 

 buds. 



Foliole, (adj. Foliolate.)A. leaflet; the sec- 

 ondary divisions of a compound leaf. 



Foliose. Covered closely with leaves. 



Follicle. An inflated seed-vessel; as that 

 of the Colutea. 



Foramen. An aperture. The foramen of 

 an ovule is an aperture through the in- 

 teguments, allowing the passage of the 

 pollen tubes to the nucleus. 



Foraminule. The ostiolum (which see) of 

 certain Fungi. 



Forcipate. Forked, like a pair of pincers. 



Forked. Separating into distinct branches, 

 more or less apart. 



Fornix. Little arched scales in the orifice 

 of some flowers. 



Fovea, (adj. Foveate, dim. Foveolate.) A 

 small excavation or pit; hence pitted. 



Foveole. The perithecium (which see) of 

 certain Fungi.
