1. Philadelphus inodórus L. A shrub 2-3 m. high, the bark of the shoots brown, 
exfoliating. Leaf-blades ovate, broadly ovate or oval, acute at the apex, rounded or 
slightly narrowed at the base, 3-10 cm. long, 1.5-5 cm. broad, glabrate or with short ap- 
pressed hairs either scattered or more copious, especially on the lower surface, prominently 
3-nerved, entire or with minute distant teeth : sepals acute : corolla 3-4 em. wide. 
On banks of streams and moist woods, North Carolina to Mississippi and Tennessee. Spring.—A 
form, possibly specifically distinct, P. inodorus strigósus Beadle, may be recognized by the thick covering 
id "ns rather stiff hairs on the lower surface of the leaves and frequently on the exterior of 
e sepals. 
2. Philadelphus grandifldrus Willd. A shrub 2-3 m. tall, the bark of the shoots 
brown, exfoliating. Leaf-blades ovate-lanceolate or elliptic, acuminate, sharply dentate, 
either rounded or narrowed at the base, 4-12 em. long, 1.5-4 cm. broad, glabrate or with 
short appressed pubescence, 3-nerved : sepals acuminate: corolla 4-5 cm. wide: capsule 
attenuate to the pedicel. 
_ On banks of streams and moist rocky slopes, Virginia to Florida, mainly along the mountains. 
Spring.—P. lazus Schrad., similar to the last, but with much narrower leaf-blades more densely 
appressed pubescent on the lower surface, and smaller and usually solitary flowers, is unknown to the 
writer in a wild state, although apparently of eastern American origin. 
3. Philadelphus gloridsus Beadle. A shrub 2-3 m. high, the bark of the previous 
season's growth dark brown, exfoliating. Leaf-blades ovate or elliptic, acute at the apex, 
either rounded or narrowed at the base, 4-10 cm. long, 1.5-5 em. broad, glabrate or with 
short appressed hairs, remotely dentate, 3-nerved : hypanthium and sepals glabrous: corolla 
3-4 em. broad: stigmas distinct : capsules abruptly contracted at the base, about 1 cm. long. 
On roeky banks of the Coosa River, northwestern Georgia. Spring. 
4. Philadelphus fldridus Beadle. A shrub 2-3 m. high, the bark of last year's 
shoots dark brown, exfoliating. Leaf-blades oval or elliptic, acute, remotely toothed, 
either rounded or narrowed at the base, 4-10 cm. long, 2-5 cm. broad, sparsely pubescent 
on the lower surface, glabrate above, prominently 3-nerved : pedicels, hypanthium and exte- 
rior surface of the acuminate sepals appressed pubescent : corolla 3-4 cm. broad: stigmas 
not united. 
On rocky slopes and banks of streams, Floyd County, Georgia. Spring. 
5. Philadelphus latifdlius Schrad. A shrub 2-3 m. high, the bark of the shoots 
gray or yellowish, not exfoliating. Leaf-blades broadly ovate or elliptic, acute at the 
apex, rounded or contracted at the base, 3-10 cm. long, 2-7 cm. wide, mostly dentate, 
softly and densely pubescent on the lower surface, glabrate or glabrous above, 3-5-nerved : 
owers racemose, the lower pair axillary : pedicels, hypanthium and exterior of the sepals 
pubescent : corolla 3-4 cm. wide: stigmas not united. 
On rocky banks of streams, especially near Nashville, Tennessee. Spring.— JP. pubescens Loisel., 
E the last but with brown bark and more numerous flowers, the lower two or three pairs of 
Which are axillary, is unknown in a wild state, but usually regarded of eastern American origin. 
6. Philadelphus intéctus Beadle. A shrub 2-3 m. tall, the bark of the shoots gray 
or ochre-color, not exfoliating. Leaf-blades ovate, oval or elliptic, acute or acuminate at 
the apex, either rounded or narrowed at the base, 3-12 em. long, 1-5 cm. broad, glabrous 
or glabrate on both surfaces, prominently 3-nerved, either entire or remotely dentate : 
owers racemose, the lower pair axillary : pedicels, hypanthium and exterior of the sepals 
glabrous : corolla 3-4 cm. wide: stigmas distinct. 
On bluffs of the Cumberland River, below Nashville, Tennessee. Spring. 
7. Philadelphus hirsütus Nutt. A shrub 1-2.5 m. tall, the bark of the previous 
season's growth brown, exfoliating. Leaf-blades ovate or ovate-acuminate, either rounded
