PHLEBODIUM (Greek, a vein). Poh/podidcew. A 

 genus of ferns related to Polypodium and sometimes 

 united with it, but differing widely in the venation, 

 which is broken up into ample areolffi, each of which 

 contain 2 or more free veinlets which bear the sori on 

 their united tips. 



aiireum, R. Br. (PolypAdium aiireum, Linn.). Lvs. 

 2-3 ft. long rising from large, scaly wide-creeping root- 

 stocks ; divisions 5-9 in. long, nearly an inch wide, with 

 copious, large, bright yellow sori. A rich ornamental 

 species from tropical America, with glaucous green 

 leaves. In Florida it grows on palmettos. 



P. glaHcum, var. Maun or P. ilayii. See Phymatodes.

PHLfiUH {phleos, an old Greek name for a kind of 

 reed). Gmminem. A genus of 10 species in temperate 

 zones. Spikelets 1-fld., in a close cylindrical spike-like 

 panicle : empty glumes 2, persistent, keeled, short- 

 awned : fl. -glume shorter, delicate, awnless. Perennials. 



prat6nse, Linn. Timothy. Herd's Grass. Figs. 

 1756, 1757. Commonly cult, for hay and for pastures, 

 either alone or in company -ndth red clover or other 

 grasses. It was introduced into Maryland about 1720, 

 from Europe, where it is native, by Timothy Hanson, and 

 hence called Timothy. The other name is said to come 

 from a man by the name of Herd, who found it growing 

 in New Hampshire and began its cultivation. It is bet- 

 ter adapted for hay than for pasture, and for the latter 

 is suited to temporary rather than permanent pasture.

PHLOMIS 1305 



PHLOGACANTHUS (Greek for flame, and acanthus). 

 AcanlhdceiE. Tall half-shrubby herbs with entire or 

 somewhat toothed lvs. : lis. white, red or greenish in 

 long terminal or short lateral spikes; calyx 5-parted, 

 segments linear, awnlike, acuminate; corolla-tube long, 

 broad, curved, limb 2-lipped, upper lip 

 erect, entire or2-lobed; lower lip 3-parted; 

 perfect stamens 2, inserted on the lower 

 part of the tube, anthers with 2 parallel 

 cells; ovary many- ovuled; capsule round or 

 obtusely 4-angled. 



Used like the others of the family as deco- 

 rative pot-plants in the greenhouse. They 

 require a rather warm, damp atmosphere 

 and a soil rich in humus. Propagated by 

 cuttings or seeds. 



thyrsifldnis, Nees. Shrub, 3-7 ft. high: 



lvs. 7 X 1% , lanceolate, glabrous : fls. orange, 



P in long, dense, villous thryses ; corolla % 



in. wide, tubular, 2-lipped. India. Cult, in 



S. Fla. Native to India. 



No description is available of P. cardinalis, 

 advertised 1893 by Saul, nor of P. Drummondii, 

 recently offered by Childs.

PHLdMlS (old Greek name used by Dioscorides). 

 Labidtm. Jerusalem Sage. About 50 species of herbs 

 and shrubs native to the Mediterranean region with 

 dense axillary whorls of rather large yellow, purple or 

 white fls. Perhaps a dozen species have been cult., but 

 they are rather coarse plants except for wild gardening 

 and among shrubbery. They are of the easiest culture. 

 The genus is placed by Bentham and Hooker next to 

 Leonotis (Lion's Ear), which, however, has an exces- 

 sively long upper lip. Phlomis plants are more or less 

 woolly, and some of the species not cult, in America are 

 conspicuously white-woolly. Lvs. all alike, or the up- 

 permost reduced to bracts: whorls many- or few-fld. : 

 fls. sessile; calj'x usually plicate, truncate or with 5 equal 

 teeth; upper lip of the corolla (galea) broad and com- 

 pressed or strongly concave, rarely narrow and falcate; 

 stamens 4, didynamous. The first three species described 

 below belong to the section Euphlomis, in which the 

 galea (upper lip of the corolla) is only shortly bearded 

 and the lateral lobes of the lower lip are small and 

 appendaged ; the last species belongs to the section 

 Phloraidopsis, in which the galea is long-bearded in- 

 side and at the margins and the lateral lobes of the 

 lower lip are nearlv as large as the middle one. P. 

 tuberosa has run wild sparingly in the East. It is a 

 vigorous and hardy species, propagating by subter- 

 ranean tubers.
