HENDEKSON'S HANDBOOK OF PLANTS. 



FIL 



modifications of the vascular system in 

 conjunction with the fructification. All 

 Ferns may be referred to one of the 

 groups Ophioglossacece, Marattiaceoe, or 

 Polypodiacece, of which the first two, 

 sometimes called pseudo-Ferns, are very 

 limited, while the latter, containing the 

 true Ferns, includes the greater portion 

 of all the known species. 



Filicales. That alliance of Acrogens to 

 which the Ferns belong. 



Filiform, Filiformis. Cylindrical and slen- 

 der, like a thread. 



Filipendulous. Where tuberous swellings 

 are developed in the middle or at the 

 extremities of filiform rootlets, as in Spi- 

 rceafilipendula. 



Fimbria. A fringe. An elastic toothed 

 membrane situated beneath the opercu- 

 lum in Urn Mosses. 



Fimbriate. Fringed. 



Fimbrialo-laciniate. Having the edge cut 

 up into divisions which are fimbriated. 



Fimbrittiferous. Bearing many little fringes, 

 as the receptacle of some Composites. 



Fimetarious. Growing on or amid dung. 



Fingered. The same as digitate, which see. 



Fish Guano. See Fertilizer. 



Fissidentece.A. natural order of Mosses, 

 remarkable for their peristome being like 

 that of Dicranum, or almost rudimentary, 

 accompanied by a totally different habit, 

 due to the flat, broad-keeled, sheathing 

 leaves. The species grow in running 

 water, and one only has at present been 

 found in Europe. Drepanophyllum, a 

 magnificent Moss, is found in Cayenne. 



Fissiparous. Propagating by a sub- division 

 of the interior of a cell into two or more 

 other cells, by the production of a mem- 

 braneous partition or septum, from the 

 lining of the mother cell. 



Fissus. Divided half way, usually into a de- 



FLO 



terminate number of segments. We say, 

 bifidus, split in two; trifidus, in three, and 

 so on; or multifidus, when the segments 

 are very numerous. 



Fistular, Fistulous. This is said of a cylin- 

 drical or terete body which is hollow, 

 but closed at each end, as the leaves and 

 stem of the Onion. 



Flabdlat us, Flabelliformis. ^Fan-shaped. 



Flaccid. Feeble, weak; bending without 

 elasticity, as some peduncles under the 

 weight of flowers; wilted or relaxed in 

 consequence of the loss of moisture. 



Flagelliform. Flexible, narrow, and taper- 

 ing, like the thong of a whip, as the run- 

 ners of many plants. 



Flagellum. A twig or small branch; also a 

 runner like that of a Strawberry. 



Flammeus, Flame-colored, Very lively scar- 

 let; fiery red. 



Flavedo. YeUowness; a disease in plants 

 in which the green parts assume that 

 color. 



Flavescens, Flavidus, Flavus. Pale yellow, 

 or pure yellow diluted. 



Flavo-virens. Green, much stained with 

 yellow. 



Fleshy. When the flesh is firm and succu- 

 lent. 



Flexible. Capable of being bent, but re- 

 turning with elasticity to its original 

 state. 



Flexuose. Ziz-zag; having a wavy direc- 

 tion, gently bending alternately inward 

 and outward. 



Flocci. Woolly threads found mixed with 

 sporules in Fungi; also any wool-like 

 hairs. 



Floccose. Covered with little tufts of hair, 

 like wool. 



Flora, (the goddess of flowers.) The aggre- 

 gate of all the species of plants inhabit- 

 ing a particular country.
