154 JOIRNAL OF THE ARNOLD ARBORETUM [vol. ii 



This points to the possibiHty that dilTercntly colored plates of the original 

 issue exist and that Drapiez's plant was copied from one which had gray 

 branches. I therefore consider P. pvhescens Loisel. the oldest name for 

 P. latifolius Schrad., particularly as the identity of these names is ac- 

 knowledged by Schrader himself, and keep P. verrucosus as the name 

 for the plant described below. 



Since all the descriptions published so far are based on cultivated 

 plants and are comparatively short, I give below a full description of 

 this species based on Mr. Palmer's specimens:

Upright shrub to 3 m. tall, with upright or somewhat recurved branches; 

 young branchlets glabrous or sometimes very sparingly pilose, yellowish 

 or reddish yellow at first, becoming red-brown at the end of the season, 

 red-brown or grayish brown with close bark the second year, the bark 

 tardily exfoliating the third year. Winter-buds minute, enclosed in the 

 base of the petiole. Leaves of the flowering branchlets elliptic-ovate or 

 elliptic to ovate-lanceolate, acute or acuminate, broadly cuneatc or some- 

 times nearly rounded at the base, 4-7 cm. long, sparingly denticulate to 

 entire or nearly so, bright green and glabrous above, lighter green and 

 strigose pubescent beneath on the whole under surface or rather densely 

 villose-strigose, the leaves of the shoots ovate or elliptic-ovate, 5-11 cm. 

 long and 3-7 cm. broad, rounded at l)ase, with 5-7 coarse triangular 

 teeth on each side, 3-nerved, with the pair of prominent veins some dis- 

 tance above the base; petioles 2 5 mm. long, on the leaves of the shoots 

 up to 7 mm. long, slightly hairy or nearly glabrous. Flowers white, 

 about 2.5-3 cm. across, in 5-7-flowercd racemes on short lateral shoots 

 with usually two pairs of leaves below the racemes and the lowest or 

 the two lower pairs of flowers in the axils of foliage leaves; internodes 

 of the raceme 1-2.5 cm.; pedicels 3-5 mm. long, strlgose-pubescent; 

 calyx-lobes ovate-oblong, short-acuminate, 6-7 mm. long, inside villose 

 near margin and apex, rather densely strigose-pubescent outside like the 

 turbinate calyx-tube; petals oval, about 1.2 cm. long and 7-8 mm. wide; 

 stamens 40-45, unequal, the longest about one-third shorter than the 

 petals; anthers ovate, 1.5 mm. long, cordate at base, pointed at apex; 

 style glabrous, about as long as stamens, divided at the apex \i ov }/^ oi 

 its length; stigmas narrower than the anthers; ovary partly superior.
