Phleg"mon*ous (?), a. [Cf. F. phlegmoneux.] Having the nature or properties of phlegmon; as, phlegmonous pneumonia. Harvey.

Phleme (?), n. (Surg. & Far.) See Fleam.

||Phle"um (?), n. [NL., fr. Gr. &?; a kind of marsh plant.] (Bot.) A ||genus of grasses, including the timothy (Phleum pratense), which is ||highly valued for hay; cat's-tail grass. Gray.

Phlo"Îm (?), n. [Gr. &?; bark.] (Bot.) That portion of fibrovascular bundles which corresponds to the inner bark; the liber tissue; -- distinguished from xylem.

Phlo*gis"tian (?), n. A believer in the existence of phlogiston.

Phlo*gis"tic (?), a. 1. (Old Chem.) Of or pertaining to phlogiston, or to belief in its existence.

2. (Med.) Inflammatory; belonging to inflammations and fevers.

Phlo*gis"tic*al (?), a. (Old Chem.) Phlogistic.

Phlo*gis"ti*cate (?), v. t. [imp. & p. p. Phlogisticated (?); p. pr. & vb. n. Phlogisticating.] (Old Chem.) To combine phlogiston with; -- usually in the form and sense of the p. p. or the adj.; as, highly phlogisticated substances.

Phlo*gis`ti*ca"tion (?), n. (Old Chem.) The act or process of combining with phlogiston.

Phlo*gis"ton (?), n. [NL., fr. Gr. &?; burnt, set on fire, fr. &?; to set on fire, to burn, fr. &?;, &?;, a flame, blaze. See Phlox.] (Old Chem.) The hypothetical principle of fire, or inflammability, regarded by Stahl as a chemical element.

This was supposed to be united with combustible (phlogisticated) bodies and to be separated from incombustible (dephlogisticated) bodies, the phenomena of flame and burning being the escape of phlogiston. Soot and sulphur were regarded as nearly pure phlogiston. The essential principle of this theory was, that combustion was a decomposition rather than the union and combination which it has since been shown to be.

Phlo"rol (?), n. [Phloretic + -ol.] (Chem.) A liquid metameric with xylenol, belonging to the class of phenols, and obtained by distilling certain salts of phloretic acid.

Phlo"rone (?), n. [Phlorol + quinone.] (Chem.) A yellow crystalline substance having a peculiar unpleasant odor, resembling the quinones, and obtained from beechwood tar and coal tar, as also by the oxidation of xylidine; -- called also xyloquinone.
