PHILODENDRON 



DD. Petioles glabrous. 



giganteum, Schott. Climbing: petioles 3 ft. long, 

 thick, cylindrical; blade cordate-ovate, 24-28 in. long, 

 16-20 in. wide, the basal lobes slightly introrse, semi- 

 ovate or obliquely semicircular, one-fourth as long as 

 the apical one, separated by a broad parabolic sinus; 

 spathe tube 2 in. long, oblong, purple; spadix very 

 thick. Trop. America. 



Irabe, Schott (P. Sellowianum, Kunth). Branches 

 rusty purple: petioles of young plant semicylindrical, 

 terete, sparsely brown-spotted, 1K-2 times longer than 

 the midrib; blade like parchment, cordate-oblong, the 

 oblong basal lobes one-half as long as the apical, sepa- 

 rated by a wide parabolic sinus, retrorse or sub-introrse ; 

 apical lobe cuspidate; spathe green outside, red within, 

 its broadly ovate blade dirty yellow; spadix shaped like 

 a finger. Rio de Janeiro. According to Engler, the 

 Mexican P. sanguineum has been called P. Imbe in 

 gardens. P. 8a*g*inewn differs in having more elon- 

 gated Ivs. which are red beneath. 



spectabile, Linden. Large, of vigorous habit: Ivs. 

 12-15 in. long, nearly as broad, silky or velvety green.

Andreanum, Devans. Lvs. rather large, cordate-ovate, 

 with short basal lobes, bronzy green. Colombia. R.H. 

 1886:36. Sparingly grown. Looks like a narrow-lvd. 

 Anthurium. 



P. Devansayanum, Lind., is a scandent species with rather 

 small glossy green Ivs. which, even to the petioles, are blood- 

 red when young. Peru. I.H. 42:48. P.Glazidvii, Hook, f., is a 

 climber something like P. crassinervium : Ivs. oblong-acute, 

 deep green, 12-18 in. long, 3-5 in. broad: spathe open, yellowish, 

 crimson within the tube. Brazil. B.M. 6813. P. imperidle is 

 mentioned in European trade lists. Engler accounts for only 

 one P. imperiale (of Schott) and that he makes a synonym of 

 P. asperatum, Koch. Sander & Co. advertise P. imperiale, var. 

 Laucheana: "a lovely trailing stove foliage plant, which is ad- 

 mirably adapted for growing on pillars or wire shapes. It is 

 quite distinct from and greatly superior to the well-known 

 P. imperiale. The habit is much more graceful, the heart- 

 shaped foliage smaller and more elegant. Down the center, 

 from either side of the broad light green midrib, extend irregu- 

 lar blotches of dark green, projecting into a clear glaucous 

 color, the edges of which are relieved by green blotches. The 

 bases of the petioles bear bright red and green phyllodes." P. 

 asperatum is a short-jointed climbing Brazilian species with 

 cordiite-ovate entire dull green Ivs. P. Mamei. Andre. Lvs. 

 eordste-ovate, acute, variegated with white: spathe partly open 

 above and whitish, the tube blood-red. Ecuador. R.H. 1883, p. 

 104; 1883:492: 1897, p. 573. I.H. 43:66. P. pertusum is Mon- 

 stera deliciosa. J ARED G. SMITH and G. W. OLIVER. 



PHLEBODIUM (Greek, a vein). Polijpodidcece. A 

 genus of ferns related to Polypodium and sometimes 

 united with it, but differing widely in the venation, 

 which is broken up into ample areolae, each of which 

 contain 2 or more free veinlets which bear the sori on 

 their united tips. 



aureum, R. Br. (Polypodium aureum, Linn.). Lvs. 

 2-!5 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. glaucum, var. Mayii or P. Mayii. See Phymatodes.

PHLEUM (phleos, an old Greek name for a kind of 

 reed). Graminece. 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. 



pratense, Linn. TIMOTHY. HERD'S GRASS. Figs. 

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

 either alone or in company with 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.

PHLOGACANTHUS (Greek for flame, and acanthus). 

 Acntithacece. Tall half -shrubby herbs with entire or 

 somewhat toothed Ivs.: fls. 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. 



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

 Ivs. 7x 1%, lanceolate, glabrous : fls. orange, 

 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.

PHLOMIS (old Greek name used by Dioscorides). 

 Labiate?.. 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-fid.: 

 fls. sessile; calyx 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 

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

 side and at the margins and the lateral lobes of the 

 lower lip are nearly 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.
