 hairs beneath: fls. large, about 1^-2 in. across, exqui- 

 sitely fragrant, with a purple spot at base of each

 ately slender, gradually broadening into the stigma; 

 calyx glabrous without. May, June. 



15. Rosace. Hybrid of unknown origin. Lvs. lanceo- 

 late, glabrous, about 134-3J4 in. long, z /% to about 1 

 in. wide, entire, on young succulent shoots and suckers

 scented; calyx glabrous without. May, June. 



16. Perle Blanche. Shrub, to about 4% ft.: Ivs. 

 ovate, medium-sized, toothed, with small stiff scat- 

 tered hairs beneath: fls. partly double, in head-like 

 clusters, sweet-scented; calyx rather hairy without. 

 May, June. 



cc. Pistils far exceeding the stamens. 



17. Falconeri, Sarg. Fig. 2904. Shrub, to 8 ft., with 

 slender, arching branches: Ivs. ovate-lanceolate, 1^-3 

 in. long, 3^-1 in. wide, acuminate, entire or very 

 minutely mucronate-denticulate : fls. in loose racemes 

 of 1-6, fragrant, about 1^4 m. across; calyx-lobes very 

 acuminate; petals rather narrow; pistils much longer 

 than the stamens; styles separating as long slender 

 filaments; stigmas scarcely broader than the styles. 

 June. Origin unknown, probably Japanese. G.F.

BB. Calyx distinctly hairy or glabrate. 



18. pubescens, Loisel. (P. latifolius, Schrad. P. 

 grandiflorus, P. W. Wats., under which name it is often 

 met with, a name commonly also applied to varieties 

 of P. coronarius and of P. inodorus, P. nivalis, and 

 many other species or supposed species; it is also 

 wrongly called P. Gordonianus) . Shrub, to 20 ft.: bark 

 of old branches grayish, either cracking when old and 

 not peeling, or peeling in little flakes, so that shreds do 

 not remain, of younger branches generally yellowish or 

 greenish yellow: Ivs. ovate to broadly elliptic or ovate- 

 lanceolate, lM-4>3 in. long, %-3 in. wide (those of 

 young succulent shoots and suckers may attain dimen- 

 sions of 7}4 X 6% in.), acute to acuminate, almost entire 

 to more or less markedly mucronate-denticulate: fls. in 

 long leafy racemes of 5-10, usually distant, somewhat 



fragrant. June, July. Term., Ala. (last, according to 

 Rydberg). Souvenir de Billiard (also cult, under the 

 names P. BUlidrdii and P. insignis) is a horticultural 

 variety, with ovate Ivs. on the average smaller than 

 in the species, about l}4-2% in. long, erroneously 

 described as a native species. Var. intectus, A. H. 



2904. Philadelphia Falconeri. 



Moore (P. intectus, Beadle). A natural variety with 

 an externally wholly glabrous calyx, and with Ivs. 

 glabrous or nearly so. Tenn. 



19. verrucdsus, Schrad. A plant of uncertain origin: 

 if hybrid, the parentage cannot be surmised. Similar 

 to preceding, but bark of old branches purplish red or 

 chestnut-brown, often peeling in shreds, of the younger 

 generally brownish or reddish. June, July. Var. 

 pendulif olius is a garden variety with slightly droop- 

 ing branchlets. 



20. Magdalenae, Koehne. Rather lower, spreading 

 shrub, to about 5% ft. : the calyx generally with fewer 

 short stiff hairs: otherwise closely resembling the pre- 

 ceding, Ivs. inclined to be smaller. 



AA. Fls. borne singly or in clusters of 1-6 at the tips of 

 the branchlets, not in racemes, except occasionally 

 in P. mexicanus. 



B. Pedicels and, externally, the calyx glabrous or nearly 

 so: Ivs. glabrous or with few scattered hairs. 



21. inoddrus, Linn. (P. corondrius var. inodorus, 

 Martyn. Deutzia corymbdsa, Hort,). Shrub, to about 1 

 ft., much resembling P. coronarius in general appear- 

 ance: Ivs. ovate to ovate-lanceolate, about 1-6 in. long, 

 K-1M in. broad, entire or with very few, usually very 

 small, distant teeth. May, June. N. C. and Tenn. to 

 Ga. and Miss. B.M. 1478. Usually hardy N. Long in 

 cult.; inferior to P. coronarius. Var. grandifldrus, 

 Gray (P. grandiflorus, Willd. P. laxus, Lindl., also of 

 Lodd. P. Idxus var. grandiflorus, Loud.). Lvs. gen- 

 erally more elongate, more coarsely toothed, especially 

 on young succulent shoots and suckers. N. C. to Ga. 

 and Fla. (last according to Rydberg), naturalized at 

 Bushkill, Pa. 



22. laxus, Schrad. (P. grandiflorus var. Idxus, Torr. & 

 Gray. P. specidsus, Schrad. P. pubescens, Lodd.). Shrub, 

 to scarcely more than 1^ ft.: Ivs. narrowly lanceolate, 

 with rarely a few ovate-lanceolate, teeth small, evenly 

 disposed, on young succulent shoots and suckers more 

 or less ovate-lanceolate, more coarsely toothed, some- 

 times with tufts of hairs in axils of lateral veins: fls. 

 white. April, May. Szechuan Province, China. B.R.
