PHLOX 



PHLOX 



limb ^-1 in. broad, lobes broad-obovate and often 

 abruptly pointed. P. tenuis, A. Nelson (var. tennis, 

 Gray) is small and slender, not villous, glabrous or 

 slightly pubescent : Ivs. mostly alternate, the blades thin 

 and linear or linear-lanceolate: fls. lavender, small, the 

 limb about J^in. across, lobes rhombic-ovate and acute. 

 P. aspera, A. Nelson. With short rigid hairs: Ivs. oppo- 

 site, the blades thick, narrow-lanceolate to linear: calyx 

 and pedicels glandular, the calyx-lobes awned; corolla 

 violet, the tube glandular-pubescent; lobes cuneate- 

 obovate, about ^in. long, mucronate. P. Roemeriana, 

 Scheele. Glabrate or somewhat hirsute: lys. mostly 

 alternate, spatulate-oblong or lanceolate, sessile, usually 

 acute or acuminate: fls. solitary or few, pink or rose- 

 colored; corolla-tube not surpassing the calyx (in this 

 differing from the other annual Texan phloxes) ; limb 

 of corolla less than 1 in. across, the lobes roundish 

 obovate and entire; ovules 4 or 5 in each cell. 



AA. Species perennial, of various habit, either pubescent 



or glabrous. 



B. Flowering st. erect and usually stiffish (Nos. 2-9}. 

 c. Plant mostly glabrous, at least below (exceptions in 



variety of No. 5). 



D. Infl. large and thyrse-like: plants tall. 

 2. paniculata, Linn. (P. decussata, Hort. P. acuminata, 

 Pursh. P. cordata, Ell. P. undulata, Ait.). SUMMER 

 PERENNIAL PHLOX of gardens, in many forms. Fig. 291 1 . 

 Plant stout and erect, 2-4 or 6 ft., glabrous: Ivs. thin, 

 oblong-lanceolate and mostly tapering at the base, 

 acute or acuminate: calyx-teeth awl-like. Woods, Pa., 



west and south. Summer. B.M. 1880. The parent of 

 the greater number of perennial phloxes of gardens, 

 although some of these may be hybrids with the next. 

 "Fls. pink-purple, varying to white," according to Gray. 

 In cult, varying much in color. This plant, in several

 P. maculata group.

forms, persists about old homesteads and sometimes 

 becomes naturalized. P. amplifdlia, Brit., with st. 

 villous, glandular above ; Ivs. broader, ranging from 

 Ind. to Tenn. and Mo., is considered by some to be a 

 form of P. paniculata. 



3. maculata, Linn. (P. pyramidalis, Smith. P. refiexa 

 and P. penduliflbra, Sweet). SUMMER PERENNIAL 

 PHLOX. Slenderer, and mostly less tall, usually with 

 purple-spotted st. : Ivs. very smooth and usually thicker 

 than those of the above, the upper ones usually 

 clasping: calyx-teeth short: fls. as in above. Range 

 of the last, and in cult., but less important horticul- 

 turally than P. paniculata. Summer. Var. suaveo- 

 lens, Brand (var. Candida, Michx. P. suaveolens, Ait. 

 P. tardifibra, Penny. P. longiflora, Sweet. P. alba, 

 Moench). St. glabrous, not spotted: fls. sweet-scented, 

 white. 



The foregoing treatment of the synonymy of the two 

 species entering into the origin of the summer perennial 

 phloxes is essentially that of Gray. Brand removes a 

 number of these names into a separate category com- 

 prising a range of hybrids, and accounts for other old 

 horticultural names, as follows: 



3a. paniculata x maculata, Brand. P. pyrami- 

 dalis, Smith; P. decussata, Lyon; P. reflexa, P. excelsa, 

 P. Wheeleriana, P. Sheperdii, P. penduliflbra, Sweet; 

 P. missourica, Salm-Dyck; P. omniflbra, P. atrocaulis, 

 P. Ingramiana, P. pulchella, P. Vernonidna, Hort.; 

 P. Youngii, P. Coldryana, Court.; P. speciosissima, 

 Maund; P. Bridgesii, P. Broughtonii, Marn.; P. Van 

 Houttei, P. Maridnna, Lindl.; P. insignis, De Jonghe; 

 P. Oldryana, Walp. Several other old Latin names are 

 also referable to this hybrid group. 



DD. Infl. small and loose or flat-topped: plants lower. 



4. ovata, Linn. (P. Carolina, Linn. P. triflbra, 

 Maund). A foot or two tall, the sts. erect from a short 

 decumbent base, glabrous or very nearly so: Ivs. nar- 

 row-ovate to oblong-lanceolate, the lower ones tapering 

 to base and the upper ones somewhat clasping: fls. pink 

 or light red, about 1 in. across, the straight or slightly 

 curving tube twice or more longer than the rather short 

 and broad calyx-teeth. Pa. to Ala., mostly in elevated 

 regions. B.M. 528. Gn. M. 2:168. 



5. glaberrima, Linn. Fig. 2912. Differs in somewhat 

 taller growth, linear-lanceolate to narrow-lanceolate 

 taper-pointed firm nearly veinless Ivs. which have 

 revolute margins, and in the narrow very sharp-pointed 

 calyx-teeth. Va. to Wis., and south to Fla.
